Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional force measurement systems use fixed images on balance plates, then the system structure is simple, but the adaptability to different testing schemes is poor
Solution Approach 1:
The patent transforms the static balance plate into a dynamic system by integrating a visual display device that can present different virtual reality scenarios. The display device is operatively coupled to the force measurement assembly, allowing the testing environment to be dynamically changed without physical modifications to the plate itself, thereby improving adaptability while maintaining relatively simple system structure.
Solution Approach 2:
The balance plate is enhanced with multi-functionality by incorporating a visual display device that can present various testing schemes, virtual reality scenarios, and interactive games. This allows a single device to serve multiple testing purposes, improving adaptability without requiring separate specialized equipment for each testing scheme.
2Measurement precision
If conventional balance systems use antiquated technology, then the system is simple, but the accuracy of balance assessment is reduced
Solution Approach 1:
The patent replaces antiquated mechanical or visual reference systems with a modern visual display device that presents virtual reality scenarios. This substitution enables more accurate and diverse balance assessment through immersive visual environments while maintaining the core mechanical force measurement functionality of the balance plate.
Solution Approach 2:
The visual display device acts as an intermediary between the force measurement assembly and the subject, providing immersive virtual reality scenarios that enhance balance assessment accuracy. The data processing device processes force measurement data and coordinates with the visual display to create adaptive testing environments, improving measurement precision through sophisticated data integration.
3Ease of operation
If conventional balance systems are cumbersome and difficult to use, then the system is simple, but the ease of operation is poor
Solution Approach 1:
The system incorporates eye movement tracking technology that automatically monitors and records subject behavior without requiring manual intervention. The data processing device autonomously processes force measurement data and coordinates visual display content, reducing the operational burden on patients and clinicians while improving ease of use.
Solution Approach 2:
The system provides real-time feedback by monitoring eye movements and force plate data, automatically adjusting the virtual reality scenarios and testing parameters. This feedback mechanism simplifies operation for users while enhancing the diagnostic capability through continuous adaptive adjustment of testing conditions.
