Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a thermally conductive member is made with high thermal conductivity material, then heat dissipation efficiency is improved, but mobility and ability to follow imaging element movement deteriorates
Solution Approach 1:
The thermally conductive member is divided into multiple layers with different material properties. The first layer (close to imaging element) uses high thermal conductivity material for heat dissipation, while the second layer (farther from imaging element) uses high mobility material for following element movement, resolving the contradiction between thermal conductivity and mobility requirements
Solution Approach 2:
The patent employs a composite structure where two different materials are combined in a layered configuration. The first material provides thermal conductivity while the second material provides mobility, creating a composite thermally conductive member that achieves both heat dissipation efficiency and adaptability to imaging element movement
2Ease of manufacture
If thermally conductive members are connected using conventional methods, then assembly is simplified, but connection reliability and prevention of disconnection deteriorates
Solution Approach 1:
The reinforcing member is strategically positioned only at the connection region between thermally conductive members, providing localized reinforcement where disconnection risk is highest, while maintaining assembly simplicity in other areas
Solution Approach 2:
A reinforcing member acts as an intermediary element between the thermally conductive members, providing additional mechanical support and preventing disconnection while allowing the primary connection method to remain simple
