Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion state monitoring systems face difficulties in determining the optimal attachment position for sensors on a subject's body parts, making it challenging for users to accurately position sensors for effective motion monitoring.
Innovation Solution
A motion state monitoring system that includes a storage unit to correlate motion to be monitored with sensor attachment positions, a display control unit to visualize these positions on a human body diagram, and a processing unit to facilitate sensor attachment based on user input, allowing easy determination and attachment of sensors at specified locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motion state monitoring system uses sensors attached to body parts without providing attachment position guidance, then the system can monitor motion states, but users cannot easily determine where to attach sensors
Solution Approach 1:
The system performs preliminary action by pre-storing the correspondence between motion types and optimal sensor attachment positions in advance. When a user selects a motion to monitor, the system automatically retrieves and displays the appropriate attachment position information, eliminating the need for users to figure out attachment locations independently.
Solution Approach 2:
The system introduces an intermediary display device that acts as a mediator between the user and the sensor attachment process. The display shows visual guidance indicating where to attach sensors based on the selected motion type, bridging the gap between the user's need for simplicity and the system's requirement for accurate sensor placement.
2Measurement precision
If the system displays detailed attachment position information for multiple motions, then users can accurately position sensors, but the system complexity increases
Solution Approach 1:
The system applies local quality by providing specific, localized attachment position information only for the motion type that the user has selected. Rather than displaying all possible attachment positions for all motions simultaneously, the system tailors the information display to the local context of the user's current selection, reducing overall system complexity while maintaining precision where needed.
Solution Approach 2:
The system performs preliminary action by pre-processing and storing the complex relationships between motions and attachment positions. This pre-computed information is then simply retrieved and displayed when needed, shifting the complexity from the operational phase to the setup phase, thereby reducing the perceived system complexity during actual use.
