Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing XR devices display images without vision corrections, then device complexity is reduced, but user experience quality deteriorates for users with vision impairments
Solution Approach 1:
The system performs preliminary actions by storing multiple pre-configured vision capability profiles (including refractive errors, color deficiencies, and visual field limitations) and automatically selecting the appropriate profile based on user identification. This allows vision corrections to be applied in advance without adding physical corrective optics to the device, thereby improving user experience while maintaining device simplicity.
Solution Approach 2:
The patent applies parameter changes by modifying image display parameters (such as focus, color mapping, and field of view) based on the selected vision capability profile. The data processing system adjusts these parameters dynamically to compensate for various vision impairments, achieving reliable user experience enhancement without increasing hardware complexity.
2Adaptability or versatility
If multiple vision capability profiles are stored and processed, then adaptability to different users is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the vision correction functionality into separate, modular vision capability profiles. Each profile contains specific parameters for different types of vision impairments (refractive errors, color deficiencies, visual field limitations). This segmentation allows the system to load and process only the relevant profile for each user without handling all possible profiles simultaneously, thereby improving adaptability while managing data processing complexity.
Solution Approach 2:
The system creates simplified copies of vision correction parameters in the form of pre-configured profiles. Instead of performing complex real-time calculations for each user, the system stores optimized parameter sets that can be quickly retrieved and applied, enhancing adaptability to different users while minimizing data processing complexity during operation.
3Device complexity
If vision corrections are applied through software processing, then device structure is simplified, but processing time increases
Solution Approach 1:
The system performs preliminary action by pre-processing and storing optimized vision correction parameters in multiple profiles. When a user selects or is assigned a profile, the corresponding corrections are already prepared and ready for application. This eliminates the need for complex real-time processing during image display, thereby simplifying device structure while minimizing processing time loss.
Solution Approach 2:
The patent implements dynamics by enabling the system to dynamically switch between different pre-processed vision capability profiles based on user selection or identification. Once a profile is selected, the associated corrections are applied efficiently without requiring dynamic recalculation, thus maintaining simplified device structure while reducing processing time for each user session.
