Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid support structure is used to firmly hold the substrate, then positioning stability is improved, but the risk of damage during attachment and detachment increases
Solution Approach 1:
The support member is designed with elastic deformation capability, transitioning from a static rigid structure to a dynamic flexible one. The support member elastically deforms during attachment to accommodate positioning variations, then maintains stable support through its restoring force, reducing damage risk while ensuring positioning stability.
Solution Approach 2:
The elastic support member acts as a cushioning element that absorbs mechanical shocks and stresses during attachment and detachment operations. By deforming elastically, it protects the fragile substrate and connection electrodes from sudden impact forces, preventing damage before it occurs.
2Manufacturing precision
If a complex positioning mechanism is used to ensure precise substrate alignment, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The support member performs multiple functions automatically through its elastic deformation characteristic. It simultaneously achieves positioning, alignment, and securement of the substrate without requiring separate positioning mechanisms. The elastic deformation enables the support member to self-adjust and self-align with the substrate, simplifying the overall device structure.
Solution Approach 2:
The support member utilizes changes in its physical parameters (deformation amount, restoring force) to achieve precise positioning. By controlling the elastic deformation within specific ranges, the system achieves accurate substrate alignment without complex mechanical positioning devices, maintaining simplicity while ensuring precision.
3Reliability
If multiple attachment points are used to secure the substrate, then connection reliability is improved, but the number of components increases
Solution Approach 1:
The support member is designed as a multi-functional component that simultaneously provides support, positioning, connection, and securing functions. A single support member incorporates multiple attachment points and structural features that perform various functions, eliminating the need for separate components and reducing overall device complexity while maintaining high connection reliability.
Solution Approach 2:
Multiple functional elements are merged into a single integrated support member structure. The support member combines positioning protrusions, attachment points, and elastic support functions in one component, reducing the total number of parts while ensuring reliable connection through multiple integrated attachment locations.
