Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus maintains a fixed mapping between real space and virtual space, then the mediated reality experience remains stable and consistent, but wireless charging efficiency deteriorates due to distance and obstructions from charging stations
Solution Approach 1:
The mapping between real space and virtual space is made dynamic rather than fixed. The system continuously adjusts the mapping parameters based on real-time wireless charging parameters (distance, obstructions, energy transfer rate) to optimize charging efficiency while maintaining acceptable mediated reality experience consistency.
Solution Approach 2:
The system changes the parameters of the space mapping (such as virtual object positions, scene orientation, or rendering priorities) in response to wireless charging conditions. When charging efficiency drops, the system modifies mapping parameters to adjust energy consumption patterns and improve charging performance.
2Use of energy by moving object
If the apparatus adjusts the mapping between real space and virtual space based on wireless charging parameters, then wireless charging efficiency improves, but the mediated reality experience may become unstable or inconsistent
Solution Approach 1:
The system implements a feedback mechanism where wireless charging parameters are continuously monitored, and the mapping adjustments are made in response to this feedback. The system can detect when adjustments are affecting the mediated reality experience and reverse or modify them to maintain experience consistency while still improving charging efficiency.
Solution Approach 2:
The system applies partial adjustments to the mapping rather than complete transformations. By making subtle, targeted adjustments to specific mapping parameters rather than overhaul the entire mapping, the system improves charging efficiency while minimizing disruption to the mediated reality experience consistency.
3Illumination intensity
If the apparatus uses more energy for rendering mediated reality content, then the virtual scene quality improves, but wireless charging performance deteriorates due to increased energy demand
Solution Approach 1:
The system renders only the necessary portion of the virtual scene at high quality, or renders scenes partially (e.g., lower resolution, reduced frame rate) when wireless charging energy availability is limited. This partial rendering approach maintains acceptable virtual scene quality while reducing energy demand to match charging performance.
Solution Approach 2:
The system dynamically changes rendering parameters (resolution, frame rate, detail level, field of view) based on wireless charging energy availability. When charging performance is good, higher quality rendering is enabled; when charging performance drops, rendering parameters are adjusted downward to match energy supply capacity.
