Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single heat dissipation member is used for the recording unit, then the device complexity is low, but the cooling performance is insufficient
Solution Approach 1:
The heat dissipation function is divided into two separate members: a first heat dissipation member with heat dissipation fins for active cooling, and a second heat dissipation member (heat dissipation sheet) for passive cooling. This segmentation allows each component to perform its specific heat dissipation function optimally, improving overall cooling performance while maintaining manageable device complexity through functional specialization.
2Reliability
If heat dissipation fins are added to increase heat dissipation surface area, then the heat dissipation performance improves, but the device volume increases
Solution Approach 1:
The patent combines two different heat dissipation approaches (active cooling with fins and passive cooling with heat dissipation sheet) into a unified heat dissipation system. The heat dissipation sheet provides additional heat dissipation surface area without significantly increasing device volume, as it can be integrated into the existing structure. This merging of approaches achieves improved heat dissipation performance while minimizing volume increase.
3Productivity
If the air cooling device is positioned close to the exhaust portion, then the airflow efficiency is high, but the space for heat dissipation members is limited
Solution Approach 1:
The patent utilizes the space in another dimension by positioning the heat dissipation members in the airflow path between the air cooling device and the exhaust portion. This arrangement allows the heat dissipation members to be placed in the available space without interfering with the airflow efficiency, as the airflow naturally passes over the heat dissipation members on its way to the exhaust.
