Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor technologies face challenges in measuring the acceleration of nonspecific parts and are not flexible enough to accommodate different types of games, limiting their ability to visualize body movement effectively.
Innovation Solution
A sensor device with a detachable attachment portion that can be attached to various positions on an object, equipped with an acquisition unit to automatically determine its attachment position, allowing for flexible measurement and processing of sensor information based on the attachment position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor device is designed to measure acceleration of a specific part in a particular game, then measurement precision for that specific application is improved, but adaptability to different games and body parts deteriorates
Solution Approach 1:
The sensor device is designed with multiple attachment positions (first, second, third attachment positions) that can be attached to different body parts, enabling the same device to measure acceleration at various locations. The control unit automatically identifies which attachment position is being used and selects appropriate measurement parameters, making the device universally applicable to different games and body parts while maintaining measurement precision.
2Device complexity
If the sensor device has fixed attachment positions, then device complexity is reduced, but ease of operation deteriorates due to manual configuration requirements
Solution Approach 1:
The control unit automatically detects which attachment position the sensor device is attached to by evaluating detection results from detection units, and autonomously determines and sets the appropriate measurement parameters. This self-service mechanism eliminates the need for manual configuration by the user, improving ease of operation while keeping the device structure relatively simple with just multiple attachment positions and detection units.
3Ease of operation
If the sensor device automatically identifies attachment position, then ease of operation is improved, but device complexity increases due to additional detection and control mechanisms
Solution Approach 1:
The sensor device is divided into distinct functional segments: multiple attachment positions with detection units that can detect attachment status, and a control unit that processes detection results to identify the attachment position. This segmentation allows the automatic identification function to be implemented through coordinated operation of simple components rather than a single complex mechanism, balancing ease of operation with manageable device complexity.
