Information principle: The information in the design process mainly includes market information, scientific and technological information, technical test information and processing technology information. Designers should master all kinds of information related to design comprehensively, correctly and reliably. Use this information to correctly guide product planning, scheme design and detailed design, so that the design can be continuously improved.
Principle of innovation: The bold innovation of designers is conducive to breaking through the shackles of various traditional concepts and practices and creating and inventing various mechanical products with unique principles and novel structures.
System principle: every mechanical product can be regarded as a technical system to be determined. Designing a product is to find the functional structure system with the method of system theory, and make the product achieve comprehensive optimization through analysis, synthesis and evaluation.
Convergence principle: in order to seek a brand-new product, divergent thinking is adopted when designing the functional principle scheme; In order to get a new product, we must synthesize all kinds of information and practice convergent thinking. Convergent thinking on the basis of divergent thinking will usually achieve good results.
Optimization principle: this belongs to generalized optimization, including scheme optimization, design parameter optimization and overall scheme optimization. That is, finish the design task efficiently, with high quality and economically.
Inheritance principle: critically absorb the achievements of predecessors, bring forth the new, carry forward and use for us. This is the principle of inheritance. Designers can master the inheritance principle wisely, carry out innovative design with twice the result with half the effort, and concentrate on solving the main problems in design.
Benefit principle: design must emphasize benefit, and both technical, economic and social benefits should be considered.
Time principle: speed up the design and development time and seize the market opportunity. At the same time, when designing, it is necessary to predict the possible changes of similar products in the product development stage to ensure that the designed products will not be outdated after they are put into the market.
Quantitative principle: scientific quantitative methods should be adopted as far as possible in scheme selection, modeling technology aesthetics, product technical performance and economic benefit evaluation.
Principle of simplification: under the premise of ensuring the function of the product, simplify the designed product as much as possible to reduce the product cost and ensure the quality. This basic principle is especially applicable to the preliminary design stage and improved design stage of products.
Audit principle: In order to realize efficient, high-quality and economical design, we must audit the information of each design step at any time to ensure that each step is correct and strive to improve the quality of product design.
