Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional subjective tests and analog equipment are used for movement assessment, then the assessment process is simple and equipment is familiar, but the assessment lacks precision and data-driven insights
Solution Approach 1:
The patent replaces traditional mechanical analog equipment with electronic sensors (accelerometers, gyroscopes, force sensors) that convert physical movement into digital data. This substitution enables precise, objective measurement of movement parameters while maintaining ease of use through familiar handheld device interfaces.
Solution Approach 2:
The patent introduces a computing device as an intermediary between the sensors and the assessment process. The computing device collects data from multiple sensors, processes it through algorithms, and generates performance scores, thereby bridging the gap between raw sensor data and clinically useful assessment results.
2Loss of information
If multiple sensors are integrated into the handheld device, then detailed movement data can be collected, but the device becomes more complex and harder to operate
Solution Approach 1:
The patent combines multiple sensors (accelerometers, gyroscopes, force sensors) into a single integrated handheld device. This merging allows comprehensive movement data collection from different modalities simultaneously while presenting a unified, familiar interface to the user, maintaining ease of operation despite the complexity of internal components.
Solution Approach 2:
The handheld device is designed to perform multiple functions: it serves as both a traditional stylus for touchscreen interaction and a multi-sensor data collection device. This multi-functionality ensures that clinicians can use the same device for both standard digital tasks and advanced movement assessment without requiring separate equipment.
3Reliability
If automated algorithms are used to calculate performance scores, then objective and consistent assessments are achieved, but the system requires more complex processing and data transmission
Solution Approach 1:
The patent implements a feedback loop where sensor data is continuously collected, processed through algorithms to generate performance scores, and then used to provide real-time or near-real-time assessment feedback. This automated feedback mechanism ensures consistent, objective evaluation while the system complexity is managed by performing calculations on the computing device rather than requiring complex hardware in the handheld unit.
