Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of components in the camera module is increased to provide more functions (autofocusing and optical imaging stabilization), then the functionality and performance of the camera module is improved, but the size and weight of the camera module increase, leading to higher damage from impacts
Solution Approach 1:
The patent applies beforehand cushioning by incorporating damper members between the carrier and housing, and between the first frame and carrier, before impact occurs. These damper members are pre-installed cushioning elements that absorb impact energy when collisions occur during autofocusing or stabilization operations, preventing direct transmission of impact forces to the lenses and other sensitive components.
Solution Approach 2:
The patent uses intermediary elements (damper members) positioned between the moving components (carrier, first frame) and the housing. These intermediary damper members act as mediators that absorb and dissipate impact energy, preventing direct collision between the carrier and housing, and between the first frame and carrier, thereby protecting the functional components from impact damage.
2Adaptability or versatility
If the number of components is increased to enable autofocusing and optical imaging stabilization operations, then the operational capability is improved, but the device complexity and susceptibility to collision damage increase
Solution Approach 1:
The patent merges the cushioning function into the existing structural components by providing damper members at critical interfaces (between carrier and housing, and between first frame and carrier). This integrating approach allows the camera module to maintain its multifunctional operational capability while incorporating impact protection without adding separate, complex protection systems.
Solution Approach 2:
The damper members are pre-installed in the structural design to provide automatic impact protection during autofocusing and stabilization operations. This beforehand cushioning approach protects the complex multi-component system from impact damage without requiring additional complex control mechanisms or active protection systems.
