Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If advanced image processing functions are implemented, then image processing capability is improved, but heat generation increases
Solution Approach 1:
The patent extracts the heat dissipation function from the general camera structure by adding a dedicated heat dissipation part with fins, separating the thermal management function from the imaging function to allow independent optimization of both
Solution Approach 2:
The patent introduces a heat dissipation part as an intermediary component between the camera body and the external environment, facilitating heat transfer from the internal components to the external air through conductive and convective mechanisms
2Temperature
If heat dissipation is improved, then temperature control is improved, but structural complexity increases
Solution Approach 1:
The patent merges the heat dissipation part with the camera body structure, integrating thermal management functionality into the existing structural framework rather than adding completely separate components
Solution Approach 2:
The heat dissipation part serves multiple functions: it dissipates heat from the camera body, provides structural support, and acts as a mounting structure for the camera, reducing the need for additional separate components
3Temperature
If metal coupling is used for heat dissipation, then heat transfer efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses a composite coupling structure combining metal coupling parts with resin bracket, leveraging the high thermal conductivity of metal for heat transfer while utilizing the molding capabilities of resin for complex geometries and integration
Solution Approach 2:
The resin bracket acts as an intermediary material between the metal coupling parts and the camera body, providing both mechanical support and thermal conduction pathways while simplifying the assembly process
