Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion sensing instrumentation is provided in wearable articles, then real-time motion analysis and feedback capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The system divides motion analysis into discrete motion primitives (basic movement units) that can be independently detected, classified, and scored. This segmentation allows complex movements to be broken down into manageable components that can be processed by the wearable device's processor, reducing the computational burden while maintaining analysis accuracy.
Solution Approach 2:
The patent introduces an intermediary processing layer that translates raw sensor data into motion primitives, which then serve as intermediates between the physical movement and the final performance metric. This intermediary representation simplifies the data processing pipeline and enables more efficient comparison against reference motion patterns.
2Ease of operation
If real-time feedback and multimedia expression are implemented, then user engagement and performance understanding are improved, but energy consumption and device complexity increase
Solution Approach 1:
The system provides feedback through periodic updates rather than continuous processing, analyzing motion at key moments when motion primitives are completed. This periodic approach allows multimedia feedback to be triggered at meaningful intervals, maintaining user engagement while reducing the sustained energy demand of continuous real-time processing.
Solution Approach 2:
The wearable device autonomously processes motion data locally to generate performance metrics and trigger appropriate feedback without requiring constant cloud connectivity. This self-service capability reduces energy consumption by eliminating the need for continuous wireless communication while still providing timely feedback to the user.
3Loss of information
If motion data is processed and shared over distributed networks, then social collaboration and performance comparison are improved, but data transmission time and network dependency increase
Solution Approach 1:
The system pre-processes motion data into standardized motion primitives and performance metrics before transmission, preparing the data in advance for efficient network communication. This preliminary processing ensures that only essential, standardized information is transmitted, reducing data volume and transmission time while maintaining the completeness of performance feedback.
4Ease of operation
If detailed motion analysis is provided without a coach, then independence and accessibility are improved, but measurement complexity and algorithm sophistication increase
Solution Approach 1:
The system transforms complex motion data into simplified performance parameters and metrics that are easy to understand for users without requiring expert knowledge. By changing the representation parameters from raw sensor data to standardized motion primitives and performance scores, the system makes detailed motion analysis accessible to independent users while managing measurement complexity through automated processing.
