Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If panels are directly fastened to the substrate layer through adhesive, then the structure is simple and easy to manufacture, but the silencing function is poor and hitting sound is large
Solution Approach 1:
The patent introduces a silencing layer as an intermediary component between the panel and the substrate layer. This silencing layer absorbs impact energy and reduces hitting sound, while still allowing for adhesive fastening. The intermediary layer resolves the contradiction by maintaining manufacturing simplicity while eliminating the harmful noise effect.
Solution Approach 2:
The patent uses a composite structure consisting of the substrate layer, silencing layer, and panel layered together. This composite material approach combines the structural integrity of the substrate with the sound-absorbing properties of the silencing layer and the surface properties of the panel, resolving the contradiction between simple construction and noise reduction.
2Device complexity
If panels are directly fastened to the substrate layer through adhesive, then the structure is simple, but the silencing function is poor and user experience is reduced
Solution Approach 1:
The silencing layer serves as a mediator that improves the silencing function without significantly increasing device complexity. It is integrated into the existing layered structure and fastened using the same adhesive method, thus maintaining simplicity while enhancing noise reduction performance.
Solution Approach 2:
The silencing layer utilizes porous material properties to absorb impact energy and reduce noise. The porous structure effectively dissipates sound waves and vibrations, improving the silencing function while maintaining a relatively simple overall device structure.
3Use of energy by moving object
If through holes are added to reduce wind resistance, then wind resistance is reduced and user effort is saved, but the device complexity increases
Solution Approach 1:
The through holes create a porous structure in the racket body that reduces wind resistance during movement. This allows air to pass through the racket, decreasing drag and the physical effort required by the user. The porous design achieves aerodynamic improvement without adding complex mechanical components.
Solution Approach 2:
The through holes utilize pneumatic principles by allowing air flow through the racket body. This reduces aerodynamic resistance and improves the efficiency of racket movement, saving user energy while maintaining a simple structural design.
