Solution Overview
Problem
The challenge is to prevent heat damage to electronic parts in smaller camera bodies of interchangeable lens digital cameras, where increased heat generation due to higher image quality and reduced space leads to potential damage from heat transfer between the imaging element and the main circuit board.
Innovation Solution
A camera body design featuring a metal heat radiating plate between the imaging element and the main circuit board, along with a thermal conductor to efficiently dissipate heat, reduces heat transfer and prevents temperature increases in the main circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera body is made smaller to reduce overall size, then the compactness of the imaging device is improved, but the space surrounding electronic parts is reduced leading to denser packing and increased heat transfer risk
Solution Approach 1:
A heat radiating plate is introduced as an intermediary component between the imaging element and the main circuit board. This plate serves as a thermal barrier that intercepts heat generated by the imaging element and redirects it away from heat-sensitive electronic parts, thereby resolving the heat transfer problem caused by compact packaging
2Volume of moving object
If the imaging element and camera controller are positioned closer together to save space, then the device compactness is improved, but the heat generated by these components increases the risk of heat damage to electronic parts
Solution Approach 1:
The heat radiating plate functions as a thermal shield positioned between the imaging element and the main circuit board containing the camera controller. It actively manages heat flow by radiating heat away from sensitive electronic components, ensuring reliable operation even when components are densely packed
Solution Approach 2:
The heat radiating plate changes the thermal parameters of the system by providing a dedicated heat dissipation pathway. It modifies the temperature distribution across the camera body, maintaining lower temperatures at critical electronic components while allowing closer component placement
