I. Overview
With the deepening of lean production, higher and higher requirements are put forward for lean design. Statistics show that 70% of the product cost is determined in the design stage. Without lean design, the achievement space of lean production will be more and more limited. How to go further in lean design is a problem that the design department has been thinking about. The application and promotion of TRIZ innovation method in enterprises not only effectively solved the practical problems encountered in technological innovation and product research and development, but also formed a number of products with independent intellectual property rights, which promoted the application of TRIZ theory in enterprises and formed a demonstration and leading role.
Second, the promotion and analysis of enterprise innovation methods
1, function analysis
In order to successfully promote the application of innovative methods in enterprises, it is necessary to clarify the purpose and function of innovative methods in combination with the actual situation and needs of enterprises, so as to use innovative methods in design activities and create value for enterprises.
According to TRIZ theory, function should be analyzed and defined first. It should be noted that innovative methods are an important part of lean R&D system. Only by clearly understanding the relationship between innovative methods and R&D system can we effectively determine its role and position in enterprise application. But TRIZ theory is aimed at technical system, and management system can also be analyzed by TRIZ theory.
TRIZ theory is a complete set of theories, including evolution law, innovation principle, contradiction matrix, separation principle, material field analysis and other innovative tools, which can be regarded as a subsystem of TRIZ theory, while innovation associations, innovation groups and other organizational forms can be regarded as a supersystem of TRIZ theory. With the system diagram, we can use TRIZ's "nine-screen method" to establish an analysis model, that is, analyze the past, present and future of systems, supersystems and subsystems, and determine the system functions of innovative methods applied in enterprises.
2. Determination of ideal solution
TRIZ theory holds that the ideal state of a technical system is to keep the advantages of the original system and overcome its disadvantages, without making the new system more complicated or showing new defects, and to realize continuous system evolution. TRIZ theory's "law of improving the ideal degree of technical system" points out: "The most ideal product should be this: the product does not exist as an entity, but its useful functions can still be realized. We call the product in this case the most ideal product; The design scheme in this case is called the idealized final result ","In fact, the most ideal product or technical system (also called ideal system) does not exist in practice. But the final result of idealization is an effort direction of product design and a process of technical system evolving to the most ideal system. " The "idealized end result" can also be called "the final ideal solution (IFR)". In the system where enterprises apply innovative methods, the final ideal solution can also be introduced to find the evolution direction of the system.
The system has the following final ideal solution:
① Hypersystem
Innovative methods are integrated into all aspects of enterprises and become an important part of corporate culture. In the process of enterprise action, we can consciously promote innovative methods and constantly improve their functions.
② System
Innovative methods are integrated into R&D system and become an inseparable part of R&D system. In R&D activities, consciously use innovative methods to solve problems and protect intellectual property rights.
③ subsystem
It has formed a complete learning and application environment for innovative tools, and designers can easily get learning opportunities and practice at any time.
The determination of the final ideal scheme also determines the direction and ultimate goal of the enterprise to apply innovative methods.
