Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent design is adopted for liquid crystal instrument panels and head-up display systems, then each display system can be optimized independently, but the integration of vehicle-mounted display panels is reduced and vehicle weight increases
Solution Approach 1:
The patent merges the liquid crystal instrument panel and head-up display system into a single integrated display device. The liquid crystal display panel and the head-up display panel are mounted together on a common backplate, sharing common structural components and mounting mechanisms. This combining approach achieves both independent optimization of each display function and high integration, resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If independent design is adopted for liquid crystal instrument panels and head-up display systems, then each display system can be optimized independently, but vehicle weight increases
Solution Approach 1:
By combining two independent display systems into one integrated device, the patent eliminates redundant structural components such as separate backplates, mounting brackets, and housing elements. The shared backplate and common mounting structure reduce the total material usage and overall weight, while maintaining the independent optimization capability of each display function.
3Adaptability or versatility
If independent design is adopted for liquid crystal instrument panels and head-up display systems, then each display system can be optimized independently, but mounting space requirements increase
Solution Approach 1:
The integrated display device mounts both the liquid crystal display panel and the head-up display panel on a single common backplate, utilizing shared mounting space and structural support. This merging approach significantly reduces the total mounting area required compared to installing two separate independent display systems, while preserving the independent optimization capability of each display function through modular design elements.
