Innovation Solution
The imaging apparatus incorporates a heat transfer unit with insulating properties connected to terminals, along with a first heat transfer member integrally formed within the housing to extend from circuit boards, enhancing heat dissipation by transferring heat to terminals and utilizing a sealing member for efficient heat transfer to the outside, while maintaining waterproof and dustproof properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging apparatus is made compact with high-performance imaging sensors, then the imaging performance is improved, but the heat dissipation becomes insufficient due to the closed, narrow space
Solution Approach 1:
A heat transfer unit with insulating properties is introduced as an intermediary component connected to the terminals. This heat transfer unit mediates between the heat-generating imaging sensor and the terminals, transferring heat to the terminals while maintaining electrical insulation, thus resolving the contradiction between compact high-performance imaging and heat dissipation
Solution Approach 2:
The terminals are given multiple functions: they serve both as electrical connection points for signal transmission and as heat dissipation paths. By making the terminals multi-functional, the patent achieves both electrical connectivity and thermal management within the compact housing space
2Temperature
If a heat transfer unit with insulating properties is connected to terminals for heat dissipation, then heat dissipation is improved, but the complexity of the device structure increases
Solution Approach 1:
The heat transfer unit is integrated with the existing terminal structure rather than being a completely separate component. This merging approach allows heat dissipation functionality to be added while minimizing the increase in structural complexity by utilizing existing structural elements
3Temperature
If heat is transferred to terminals for dissipation, then temperature control is improved, but the insulation requirements become more stringent to prevent electrical interference
Solution Approach 1:
The heat transfer unit with insulating properties acts as a mediator that simultaneously addresses heat transfer and electrical insulation requirements. The insulating material in the heat transfer unit prevents electrical interference while allowing thermal energy to pass through, thus meeting both temperature control and insulation requirements without additional complex insulation structures
