Engineering Contradiction Analysis
1Measurement precision
If multiple specific sensors are used for biomechanical assessment, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single biomechanical sensing device that can perform multiple assessment functions through one set of sensors. The device integrates accelerometer, gyroscope, and magnetometer to simultaneously capture various biomechanical parameters (linear acceleration, angular velocity, magnetic field orientation) across different body segments, eliminating the need for multiple specialized sensor systems while maintaining comprehensive measurement capability.
Solution Approach 2:
The patent merges multiple sensing functions into a single integrated device. By combining accelerometer, gyroscope, and magnetometer components within one biomechanical sensing unit, the system consolidates what would traditionally require separate sensor systems into a unified platform that can assess various biomechanical parameters simultaneously, reducing overall system complexity.
2Measurement precision
If traditional assessment devices are used, then measurement precision is maintained, but duration of action is limited due to inability to collect data long-term
Solution Approach 1:
The patent implements continuity of useful action by designing a wearable biomechanical sensing device that can continuously collect data over extended periods. The device is equipped with wireless communication capabilities and can operate continuously to monitor biomechanical parameters during daily activities, enabling long-term data collection for comprehensive assessment of physical activities, gait patterns, and movement characteristics without requiring repeated device removal or reconfiguration.
3Device complexity
If general-purpose motion sensing devices are used, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The patent applies local quality by strategically positioning the biomechanical sensing device at specific locations on the human body where precise measurement is most critical. The device is designed to be worn on body segments where biomechanical assessment is needed, and the sensor orientation and placement are optimized to capture accurate local movement data, ensuring that measurement precision is maintained despite using a general-purpose sensor platform.
