Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rehabilitation methods are used for head-eye coordination exercises, then treatment can be provided to patients with inner ear balance system damage, but there is no way to quantify head, eye, and postural movements to assess functional recovery
Solution Approach 1:
The patent combines multiple measurement functions into a single integrated system. The eye movement tracking device and postural sway detection device are merged into one system that simultaneously measures both eye movement and postural parameters, allowing comprehensive assessment of head-eye coordination while managing device complexity through integration.
Solution Approach 2:
The measurement system is designed to perform multiple functions: tracking eye movement, detecting postural sway, and assessing head-eye coordination. This multi-functional approach enables the system to quantify various aspects of inner ear balance system functionality using a single apparatus, improving measurement precision without proportionally increasing complexity.
2Loss of information
If multiple devices are used to measure eye movement and postural sway simultaneously, then comprehensive data can be collected, but the device complexity and difficulty of operation increase
Solution Approach 1:
The patent merges eye movement tracking and postural sway detection into a single integrated measurement system. This combination allows comprehensive data collection on both eye movement and postural parameters simultaneously, while the integrated design simplifies operation compared to using separate devices.
Solution Approach 2:
The system provides real-time feedback through numerical scores that quantify eye movement and postural stability. This feedback mechanism simplifies operation by automatically processing measurement data and presenting results in an easily interpretable format, reducing the operational complexity of analyzing raw measurement data.
3Reliability
If numerical scoring system is implemented, then objective documentation of patient functionality is enabled, but data processing complexity increases
Solution Approach 1:
The patent implements a numerical scoring system that provides objective feedback on patient functionality. The data processing device automatically calculates scores based on measured eye movement and postural parameters, enabling reliable and objective documentation of functional status while managing data processing complexity through automated algorithms.
Solution Approach 2:
The measurement system performs self-assessment by automatically processing measurement data and generating numerical scores without requiring complex manual analysis. This self-service capability enables objective documentation of patient functionality while reducing the complexity of data processing through automated score calculation.
