Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid contact structure is used for mounting internal components, then fixation strength is improved, but damage probability during drop or collision increases
Solution Approach 1:
The mounting member is designed with specific deformation amount parameters (0.015mm to 9.30mm) to transform the rigid structure into a controlled elastic structure. This parameter change allows the mounting member to absorb impact energy through elastic deformation while maintaining adequate fixation strength, thereby reducing damage probability during drops or collisions.
Solution Approach 2:
The mounting member is pre-designed with elastic buffering capability through its material selection and structural configuration. Before any drop or collision occurs, the mounting member is already configured to provide elastic cushioning, converting potential rigid contact damage into elastic buffer protection, thus preventing component damage in advance.
2Reliability
If elastic buffer contact is used to reduce stress, then damage probability is reduced, but fixation stability may worsen
Solution Approach 1:
By precisely controlling the deformation amount parameters of the mounting member within the range of 0.015mm to 9.30mm, the invention achieves an optimal balance between elastic buffering and fixation stability. The parameter optimization ensures that the mounting member provides sufficient elastic cushioning to reduce damage probability while maintaining adequate fixation stability for component mounting.
