Summary: The article passes the analysis of pair of products plan processes, the design course that offers whole product is a design process that faces a function. From the function definition and function analyse hand, gave out the course that the function builds a model. Undertake on the foundation that the function analyses the function builds a model, deciding plethoric function and useful function, inadequate function, harmful function is the base that undertakes the function cuts out. On the foundation that analysing the product innovation that is based on TRIZ academic function to cut out to devise common measure, to side of inclined guide pillar the orgnaization that smoke core undertook the function builds model and function to cut out, built improve functional model, it is a foundation in order to improve functional model, to side of inclined guide pillar the orgnaization that smoke core undertook innovating designing, the product innovation that applied example says to palpability is based on TRIZ theory function to cut out designs methodological effectiveness. The evolution of foreword technology system is a foundation with raising its ideal to spend, the ultimate goal that product innovation designs also is to raise its ideal to spend in order to get used to human demand rise ceaselessly. The function cuts out is the method that the problem of a kind of analysis in TRIZ theory and technical system improve, adopt models of pair of technical system function build and analyse, purify is put in the functional component of the problem, undertake cutting out, delete this function, the system that implements a product then is improved. Pass the technical system after cutting out, its structure more simplify, manufacturing cost is lower, and changeless or it is better that function maintains, make product more tend ideal is solved. The function cuts out is one kind raises product ideal to spend, implement the effective method that product innovation devises. The article was discussing TRIZ academic function to cut out on methodological foundation, basis function cuts out methodological flow undertook side direction of injection mould inclined guide pillar draws the innovation design of core orgnaization. The process of products plan of 1 function analysis is a complex process, overall for can include 4 level such as design of demand analysis, concept, technology design and detailed design. The design process of the product also is the process that realizes a series of functions, demand analyses level to be a target in order to satisfy the demand function of the user: Notional design phase structure of function of demand function translate into; Technical design and detailed design phase implemented the functional orgnaization change to physical structure, realize the function of the product finally. The design process of whole product is a design process that faces a function. Functional analysis is right the system undertakes the function is decomposed, decide plethoric function and useful function of the system, inadequate function, harmful function, in order to help the mutual connection between each the architect's more lucid component in understanding a system and interaction, find the problem that the system exists then. It is a foundation in order to have a product, pass functional analysis, build the functional model of the product, the innovation design that can be a product provides strong safeguard. Functional model is a kind of description of pair of system functions, its build a process to be as follows: The 1st pace: The component of definite system, goods and exceed a system relevantly with the system; The 2nd pace: Affirmatory component, goods and super- the action between the system concerns and functional sex language is stated; The 3rd pace: Define functional kind; The 4th pace: With all sorts of function symbols expressive component, goods is mixed exceed system and functional type to join model of scale system function. The 5th pace: Pass an analysis, definite system puts the issue that be in. The component of systematic function model, goods, expression that transcends system and functional genre is shown 1 times like the graph. Modular procedure is established in systematic function in, can decide according to common sense or experience to simple system each function component, goods is mixed exceed a system; To complex system, the method such as the much screen method that can use TRIZ theory, goldfish law and retrorse fishbone graph builds functional model of the system. Graph sketch map of model of 1 system function the effective method of the problem that 2 functions cut out cutting out is to solve the system that analyses discovery by the function to exist, also be a kind of method that improves innovation to the system. Of the insufficient action that carries pair of system existence, superfluous action and ill effect function cut out, with decrease or eliminating systematic defect, improved whole function model, the ideal that improves a system is spent. After the course cuts out the functional component existence problem is deleted, the method that the function that so this component place provides can adopt TRIZ theory to offer comes true, basically have the following kinds of methods. Of principle of innovation of 1) basis TRIZ multi-purpose sexual principle, the function that original component realizes by other component or exceed systematic implementation; Of principle of innovation of 2) basis TRIZ serve a principle oneself, the function that original component realizes by suffer action him element to come true; 3) if the function is not necessary, the function that deletes original component implementation and original component realize action other people of the function; The detached method that theory of 4) application TRIZ solves physics to contradict will solve the physics that needs a function not to need this function again already contradictory problem. The innovation design that should have a product with the method that the function cuts out basically is to be aimed at existing product, cut out problem function component, to the new issue of generation, the tool such as solution of knowledge base of the invention principle that can apply TRIZ theory, effect, standard will solve. Its are main move is as follows: The 1st pace: Study a target certainly; The 2nd pace: Undertake to studying object system the function is analysed, build functional model: The 3rd pace: Plethoric function and the harmful function that exists in affirmatory function model, insufficient function, undertake the function cuts out; The 4th pace: Analyse the problem that after cutting out, appears, the settlement that uses TRIZ theory invents the tool of the problem to solve a problem; The 5th pace: Function of the system after cutting out builds a model; The 6th pace: Produce new innovation to devise plan. 3 case are analysed to shape model the side direction opening that attend or side direction groove, the side direction component that middling of injection mould structure uses formula of inclined guide pillar with the orgnaization that smoke core. Its structure included side direction to shape component, motion component, transmission component, locking component and spacing component, if pursue,2 are shown. In process flying a model, the mould flies a model along cent face, movable mould moves backward, below the drive of inclined guide pillar, side slide block drives side core to finish side to smoke core, at the same time side slide block by spacing of orgnaization of spacing of bedspring pull rod, add up to the accurate restoration of modular process in order to assure; When combining a model, inclined guide pillar inserts slide block of side of drive of inclined feed hole to drive side core restoration, wedge tightens an effect that has locking side slide block, whole orgnaization asks the action is accurate, credible. Nextpage pursues side of 2 inclined guide pillar takes core machine composition of a picture side direction of inclined guide pillar divides the 2 injection mould that carry a lid for some company product model with the orgnaization that smoke core, this orgnaization has side to take core power bigger, productivity achieves the advantage such as automation production high, easily, but there also is mould structure in using a process relatively complex, inclined guide pillar changes easily inconvenience of form, maintenance and maintenance cost are advanced problem, cannot satisfy an enterprise to produce demand, put in the difference with particular move with good solution, need undertakes innovating designing. 3. Side of 1 inclined guide pillar smokes core orgnaization function to analyse side of existing inclined guide pillar to smoke what core orgnaization uses is motor-driven side direction cent with the orgnaization that smoke core, when flying a model, the master piece flying a model that relies on inject machine is motivation, shape strength effect at side direction through inclined guide pillar the spare parts makes its side smokes core, when combining a model by rely on it to make side direction shapes spare parts restoration. Undertake to having an orgnaization structure and movement are analysed so, the functional model that builds a product decides an issue. Above all, smoke core orgnaization to have input and output concern with side of inclined guide pillar certainly each exceed a system: Decide pattern plate, movable mould board and inject machine; Next, the goods of definite system is model; Next, decide each function component and its action, type and the functional model that side of scale inclined guide pillar smokes core orgnaization, if pursue,3 are shown. Graph side of 3 inclined guide pillar smokes model of core orgnaization function the goods that this function model conveyed side of inclined guide pillar to smoke core orgnaization with graphical means, component and exceed the correlation between system and them. Pass the analysis that concerns to these, from side of inclined guide pillar side of the orgnaization that smoke core takes the point of view of core system function, can discover the problem that existing orgnaization exists, if inclined guide pillar uses meeting generation for long to be out of shape, formed the action of useful inadequacy to side slide block; Bedspring is used for long, power is insufficient and same the action that is a kind of useful inadequacy to the spacing of side slide block, perfecting these functions is the jumping-off place that undertakes product innovation is designed. 3.
Side of 2 inclined guide pillar smokes core orgnaization function to cut out through the analysis above, press the principle that TRIZ academic function cuts out, the functional element that has a problem, namely the bedspring in inclined guide pillar and orgnaization of spacing of bedspring pull rod cuts out, after the bedspring in orgnaization of spacing of bedspring pull rod is cut out, spacing orgnaization cannot realize spacing function, because this can consider orgnaization of spacing of pull rod of will whole bedspring,cut out. Through afore-mentioned cutting out, its produced two new issues as a result: Use what kind of drive means: Use what kind of spacing means. What kind of to using drive means problem, the effect in can applying TRIZ will offer the train of thought that solves a problem. In adopting pair of effect knowledge bases " mobile solid matter " the function undertakes inquiring, can get the effect related to this problem, if heat expands, inertial, Archimedes's principle, bedspring is out of shape and magnetism sends systole to wait. Couple is real circumstance, to make drive construction of system simple, operate convenient, cost to reduce, can choose bedspring to be out of shape effect, the generation below the action that makes side slide block regains power in bedspring moves, smoke core in order to realize side direction. What kind of to using spacing means problem, after TRIZ function cuts out the problem component cuts out, the function that so this component place provides lost the offer person of its function, the settlement that TRIZ theory offers the method of this problem is: The function that place of the component that be deleted realizes by other component or suffer action him element to come true, in this method and 40 innovation principle multi-purpose sexual principle and answer relatively from service principle. Basis TRIZ theory solves the function after cutting out to lack the method that misses an issue, the function of former inclined guide pillar is to open slide block of side of the drive when the model to undertake side smokes core, add up to restoration of slide block of side of the drive when the model, will inclined now guide pillar cuts out, the flexibility of usable bedspring is out of shape will realize modular side to take core function, function of restoration combining a model is tightened by wedge piece will come true, make former wedge close piece by do not move become movable; After orgnaization of former bedspring pull rod is cut out, its function can come true by spacing bolt, in order to assure the fixed position of a slide block of the side after the model. Will movable wedge is close piece with spacing bolt union rises, to side of inclined guide pillar the orgnaization that smoke core undertakes improvement innovating, if the graph is shown 4 times,the side after improving smokes the functional model of core orgnaization. Graph the 4 side after improving smoke model of core orgnaization function 3.
Program of design of 3 final innovation cuts out through TRIZ function to side of inclined guide pillar the orgnaization that smoke core undertakes innovating, designed side of wedge slide block to smoke core orgnaization, if pursue,5 are shown. This orgnaization basically included wedge slide block, guide the component such as slide block of bolt of chute, spacing, bedspring, side and side core. Inject shapes after finishing, the mould flies a model along cent face, side slide block 5 strength effect restores to fall to move up in bedspring implementation side smokes core, after smoking core to finish, realize fixed position by spacing bolt. In process combining a model, below effect of strength combining a model, calm pattern plate drives wedge slide block 1 move right, force side slide block 5 be down athletic restoration. This orgnaization movement is accurate, reliable, contented business demand. Graph side of 5 wedge slide block smokes core orgnaization 4 last words take the side that improves around core orgnaization system to undertake contrast, the structure after improving decreased than improving the structural component amount before 40% , action is not worth a function to be eliminated entirely, number of the interaction between component decreased near 31% , useful function number increased 15% , make an appointment with of useful function number and component number than increasing 41% , construction of system got bigger simplify, systematic ideal is spent rise apparently. With the function to the system the analysis is a foundation, apply TRIZ to cut out theoretically method, it is the efficient way that raises technical system ideal to spend. From the point of the angle of systematic performance, the function in using TRIZ theory cuts out the method undertakes injection mould side draws the innovation design of core orgnaization, with side of wedge slide block the orgnaization that smoke core replaces side of inclined guide pillar to smoke the injection mould of the orgnaization, its structure is compact, machine handy, movement reliable, maintenance is convenient, once component wears away hind, the adjustment that can pass spacing bolt undertakes the correction after wearing away, reduced the cost of injection mould mould.
