Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical alignment mechanisms are used to ensure accurate binocular alignment, then alignment accuracy is improved, but device size and weight increase
Solution Approach 1:
The patent replaces complex mechanical alignment mechanisms with an electronic image processing system. The lensing devices project images onto a focal plane, and electronic means modify the images to adjust binocular alignment, eliminating the need for bulky mechanical fixtures while maintaining high alignment accuracy.
Solution Approach 2:
The patent changes the alignment adjustment mechanism from mechanical physical adjustment to electronic parameter modification. By modifying image parameters (position, orientation) electronically after projection, the system achieves precise alignment without additional mechanical components, thereby reducing device weight.
2Manufacturing precision
If mechanical alignment mechanisms are used to ensure accurate binocular alignment, then alignment accuracy is improved, but device volume increases
Solution Approach 1:
The patent replaces mechanical alignment mechanisms with an electronic image processing system. The lensing devices project images onto a focal plane, and electronic means modify the images to adjust binocular alignment, eliminating the need for bulky mechanical fixtures while maintaining high alignment accuracy.
3Manufacturing precision
If elaborate alignment procedures are used to achieve accurate binocular alignment, then alignment accuracy is improved, but alignment time increases
Solution Approach 1:
The patent incorporates alignment capabilities directly into the device design, with lensing devices that project images onto a focal plane and electronic means that can automatically adjust alignment. This preliminary integration of alignment functionality eliminates the need for separate elaborate alignment procedures, reducing alignment time.
Solution Approach 2:
The electronic means can monitor and adjust image alignment in real-time, providing feedback control that accelerates the alignment process compared to manual procedures, thereby reducing the time loss associated with alignment adjustments.
4Adaptability or versatility
If mechanical IPD adjustment mechanisms are used to accommodate varying inter-pupil distances, then adaptability is improved, but device size increases
Solution Approach 1:
The patent replaces mechanical IPD adjustment mechanisms with electronic image modification. The electronic means can adjust image parameters independently for each eye, accommodating varying inter-pupil distances without requiring mechanical movement, thereby maintaining adaptability while reducing device weight.
