Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional balance systems with fixed images are used, then the device complexity is reduced, but the adaptability to different testing schemes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the visual display content changeable and adaptable rather than fixed. The system can dynamically switch between different virtual reality scenarios and testing protocols based on the subject's needs, allowing the same hardware to serve multiple testing purposes without requiring separate physical setups for each test type.
Solution Approach 2:
The patent implements universality by designing a single force measurement system that can perform multiple balance assessment functions through software-controlled visual displays. Instead of having separate fixed image backgrounds for different tests, the system uses one versatile display that can present various virtual reality scenarios, making the device applicable to diverse testing schemes.
2Measurement precision
If conventional balance systems with fixed images are used, then the ease of operation is improved, but the measurement precision deteriorates
Solution Approach 1:
The patent applies feedback by implementing real-time monitoring of the subject's balance performance and automatically adjusting the visual display and testing parameters accordingly. The system monitors subjects during virtual reality scenarios and can dynamically modify test conditions based on observed performance, providing customized feedback that enhances assessment accuracy while maintaining user-friendly operation through automated adjustments.
