Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special hardware facilities are configured for spatial positioning, then spatial positioning function is achieved, but device complexity and cost increase
Solution Approach 1:
The display device integrates multiple functions into a single system. The display screen serves both as a visual output device and as a spatial positioning device by incorporating light sources and sensing pixels directly into the display structure, eliminating the need for separate spatial positioning hardware
Solution Approach 2:
The patent merges the display function and spatial positioning function into one integrated device. The light source structure and pixel layer are combined with the display substrate, creating a unified system that performs both display and spatial positioning without requiring additional independent hardware facilities
2Reliability
If additional hardware facilities are added for spatial positioning, then spatial positioning capability is provided, but occupied space increases
Solution Approach 1:
The spatial positioning components (light sources and sensing pixels) are merged into the display screen structure itself, utilizing the existing physical space of the display device rather than adding separate external hardware that would occupy additional space
Solution Approach 2:
The display screen serves dual purposes: visual display and spatial positioning. This multi-functionality eliminates the need for separate dedicated spatial positioning hardware facilities that would require additional space
3Reliability
If special hardware facilities are configured for spatial positioning, then spatial positioning function is achieved, but cost increases
Solution Approach 1:
The display device performs both display and spatial positioning functions using the same hardware components, eliminating the need to manufacture and assemble separate dedicated spatial positioning devices, thereby reducing overall system cost
Solution Approach 2:
By combining spatial positioning components with the display structure, the patent reduces the total bill of materials and assembly complexity, leading to lower manufacturing costs compared to providing separate independent spatial positioning hardware
