Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion sensors and learning models are used to estimate body movements and generate three-dimensional movement models, then measurement precision and reliability of movement detection are improved, but device complexity and computational requirements increase
Solution Approach 1:
The system segments the complex task of movement analysis into multiple components: motion sensors capture raw data, learning models estimate body movements from sensor outputs, and three-dimensional movement models visualize the results. This segmentation allows each component to be optimized independently while maintaining overall system precision.
Solution Approach 2:
The patent introduces an information processing device as an intermediary between the motion sensors and the wearable display device. This intermediary handles the complex computational tasks of estimating body movements and generating three-dimensional models, thereby reducing the computational burden on the wearable device while maintaining high measurement precision.
2Measurement precision
If multiple motion sensors are deployed to capture comprehensive body movement data, then measurement precision is improved, but device complexity and data processing requirements increase
Solution Approach 1:
The motion sensors are designed to serve multiple functions: capturing acceleration data, estimating body movements through learning models, and contributing to three-dimensional movement model generation. This multi-functionality allows the same sensors to address various measurement needs without requiring additional specialized devices.
Solution Approach 2:
The system creates virtual copies of physical body movements through three-dimensional movement models. These digital replicas allow comprehensive analysis and visualization of movements without requiring physical markers or additional sensing equipment, thereby maintaining measurement precision while reducing the quantity of physical components.
3Ease of operation
If real-time three-dimensional movement models are generated and displayed through augmented reality, then user interaction and visualization quality are improved, but energy consumption and processing power requirements increase
Solution Approach 1:
The system performs preliminary computation of three-dimensional movement models and movement estimations in advance, storing results that can be quickly retrieved and displayed in real-time. This preliminary action reduces the computational burden during actual use, thereby lowering energy consumption while maintaining high visualization quality and ease of operation.
Solution Approach 2:
The wearable display device leverages the computational capabilities of the integrated system to automatically generate and update three-dimensional movement models without requiring external processing. This self-service approach optimizes energy usage by performing necessary computations locally while maintaining real-time display performance.
