Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the roller size is increased to improve heat dissipation, then heat dissipation performance is improved, but the device thickness increases
Solution Approach 1:
The heat dissipation member is nested inside the roller structure, with the roller forming an outer shell that contains the heat dissipation member. This allows the heat dissipation functionality to be integrated within the existing roller volume without increasing the overall device thickness, effectively resolving the contradiction between heat dissipation performance and device compactness
2Ease of manufacture
If circuit boards are disposed outside the roller for easy access, then ease of manufacture is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The heat dissipation member acts as an intermediary between the circuit boards and the roller structure. The circuit boards are mounted on the heat dissipation member, which serves as a thermal conduit to transfer heat from the circuit boards to the roller's outer shell, enabling effective heat dissipation while maintaining ease of circuit board assembly and access
