Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources and image generators are installed in the head-up display, then the display functionality is improved, but heat accumulation increases causing performance degradation and potential damage
Solution Approach 1:
The heat dissipation mechanism is divided into separate heat dissipation units, each corresponding to different light sources and image generators. This segmentation allows independent heat management for each component, effectively addressing the heat accumulation problem while maintaining multiple light sources for enhanced display functionality.
2Loss of energy
If heat dissipation structures are added to the head-up display, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The heat dissipation mechanism integrates heat dissipation units directly into the existing housing structure of the head-up display. By combining the heat dissipation function with the housing, the design achieves effective heat dissipation without significantly increasing device complexity or requiring separate standalone heat dissipation components.
3Reliability
If separate heat dissipation units are provided for each light source, then heat dissipation effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The housing structure serves multiple functions: it provides mechanical support for the light sources and image generators, and simultaneously acts as a heat dissipation structure. This multi-functionality reduces the need for additional dedicated heat dissipation components, thereby lowering manufacturing costs while maintaining effective heat dissipation through the integrated units.
