Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion capture technologies are used to record patient movement, then the ability to capture motion information is improved, but the complexity of the system increases
Solution Approach 1:
The patent uses camera systems to capture visual copies of patient movement rather than direct mechanical or optical measurement systems. Multiple camera angles create visual representations that are processed into motion information, reducing the need for complex physical sensors while maintaining measurement capability
Solution Approach 2:
The patent replaces mechanical motion capture systems (with physical markers and trackers) with optical camera-based systems. This substitution reduces mechanical complexity while enabling digital processing of motion data through image analysis algorithms
2Loss of information
If multiple pieces of moving image information are collected for comparison, then the ability to analyze rehabilitation progress is improved, but the difficulty of processing and synchronizing the information increases
Solution Approach 1:
The patent introduces motion information as an intermediary data layer that bridges multiple moving image sources. This intermediate representation standardizes different video formats and timing, enabling synchronized comparison without directly processing the complexity of multiple raw video streams
Solution Approach 2:
The patent divides the analysis into discrete motion frames and time points, allowing individual frames from multiple video sources to be extracted, synchronized, and compared independently. This segmentation transforms continuous video data into manageable discrete units for systematic analysis
3Reliability
If motion information is synchronized with moving images for display, then the effectiveness of rehabilitation evaluation is improved, but the time required for processing increases
Solution Approach 1:
The patent performs preliminary extraction and organization of motion information from video streams before the actual comparison and display phases. Motion data is pre-processed and timestamped in advance, enabling faster synchronization during evaluation without real-time processing delays
