Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional optical systems are used in head-mounted displays, then basic imaging function is achieved, but optical quality is unstable and design is not thin enough
Solution Approach 1:
The optical system segments the adjustment function by wavelength, with separate adjustment components for different wavelength ranges. This segmentation allows each component to be optimized independently, achieving stable optical quality while maintaining a compact overall structure suitable for thin head-mounted display designs.
Solution Approach 2:
The patent introduces a spectral dimension to the optical adjustment, transitioning from conventional spatial-only adjustment to spectral-spatial adjustment. By adding wavelength-based adjustment components, the system achieves stable optical quality through multi-dimensional control while keeping the physical form factor thin.
2Adaptability or versatility
If single-wavelength adjustment is used, then simple structure is maintained, but diverse imaging options for users are not provided
Solution Approach 1:
The adjustment assembly is segmented into multiple adjustment components, each corresponding to different wavelength ranges. This segmentation enables diverse imaging options for different colors while keeping each individual component relatively simple, thus increasing versatility without excessive complexity.
Solution Approach 2:
The adjustment assembly is designed with multi-functionality, where each adjustment component can handle specific wavelength ranges. This universal design allows a single assembly to provide diverse imaging options across the visible spectrum, achieving adaptability without requiring entirely separate systems for each wavelength.
3Measurement precision
If wavelength-specific adjustment components are added, then imaging precision is improved, but device complexity increases
Solution Approach 1:
Each adjustment component is designed with local quality optimized for its specific wavelength range. This allows high precision adjustment for each wavelength band while keeping the overall device complexity manageable, as each component is specialized rather than requiring a single complex universal component.
Solution Approach 2:
The adjustment components are designed to be dynamically adjustable, allowing the system to adapt to different imaging requirements. This dynamic capability provides high precision for each wavelength while maintaining operational simplicity, effectively managing the trade-off between precision and complexity.
