Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stationary multi-camera systems are used for motion capture, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent replaces complex mechanical multi-camera systems with mobile computing devices that have built-in sensors (accelerometers, gyroscopes, magnetometers) to capture motion data. This substitution of mechanical systems with electronic sensing systems reduces device complexity while maintaining measurement precision for motion capture applications.
Solution Approach 2:
The patent utilizes mobile devices that serve multiple functions: they act as both the motion capture sensors and the processing/computing units. This multi-functionality eliminates the need for separate dedicated motion capture equipment, reducing overall system complexity while maintaining measurement capabilities.
2Measurement precision
If stationary multi-camera systems are used for motion capture, then measurement precision is improved, but ease of operation deteriorates due to fixed installation requirements
Solution Approach 1:
The patent transitions from static, fixed installations to dynamic, mobile motion capture systems. The use of portable mobile devices allows the system to be easily moved and deployed in different locations, significantly improving ease of operation and portability while maintaining measurement precision through the devices' integrated sensors.
3Ease of operation
If motion capture data is collected without comparison to previous data, then ease of operation is improved, but loss of information increases due to lack of contextual analysis
Solution Approach 1:
The patent implements automatic comparison of current motion capture data with previously stored motion patterns from the same user or other users. This preliminary action of data comparison and contextual analysis is performed automatically by the system, maintaining ease of operation while preventing loss of information by providing meaningful context through pattern recognition and comparison.
4Device complexity
If custom equipment fitting is performed without data mining, then device complexity is reduced, but manufacturing precision deteriorates due to lack of personalized analysis
Solution Approach 1:
The patent enables automated equipment fitting recommendations where the system performs data mining and analysis on collected motion capture data to generate personalized equipment fitting suggestions. This self-service approach allows the system to automatically analyze user-specific motion patterns and provide customized equipment recommendations, improving manufacturing precision without significantly increasing perceived device complexity for the user.
