Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate cooling structure for the recording medium is added, then cooling effectiveness is improved, but device size increases
Solution Approach 1:
The patent merges the cooling function for the recording medium with the existing air-cooling duct structure. The first air-cooling duct is positioned to simultaneously cool both the recording medium and the control circuit board, eliminating the need for a separate dedicated cooling structure and thus preventing size increase while maintaining effective cooling.
Solution Approach 2:
The first air-cooling duct serves multiple functions: it cools the recording medium, cools the control circuit board, and utilizes the space between the battery housing and the second board. This multi-functional design allows a single structure to address multiple cooling needs without adding extra components that would increase device size.
2Loss of energy
If cooling performance is enhanced for the recording medium, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines the cooling pathways for the recording medium and control circuit board into a single first air-cooling duct system. This integration reduces the number of separate cooling components and pathways, simplifying the overall structure while maintaining effective heat dissipation through the fan-generated air current.
Solution Approach 2:
The first air-cooling duct utilizes the vertical space between the battery housing and the second board, effectively using three-dimensional space within the existing device footprint. This spatial optimization allows enhanced cooling capacity without adding external complexity or increasing the overall device volume.
