Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals performing exercises often fail to maintain correct postures when not supervised by a coach or physiotherapist, leading to reduced effectiveness and potential harm.
Innovation Solution
A movement assessing system that includes an angle arithmetic unit, limb analysis unit, center of gravity arithmetic unit, balance analysis unit, and index calculation unit, which use sensors and databases to analyze limb angles and balance accuracy, providing real-time feedback and suggestions for improving posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coach or physiotherapist is used to correct postures, then exercise safety and correctness are improved, but dependency on external supervision increases and autonomy decreases
Solution Approach 1:
The system enables self-service by providing automated posture assessment and feedback through sensors and processing units, allowing individuals to independently monitor and correct their exercise postures without external supervision, thus achieving both reliability and autonomy
2Measurement precision
If multiple sensors and analysis units are added to assess movement accurately, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the assessment function into separate modular units: angle arithmetic unit, center of gravity arithmetic unit, limb analysis unit, balance analysis unit, and index calculation unit. Each unit handles a specific aspect of movement analysis, improving measurement precision while maintaining manageable complexity through functional segmentation
3Productivity
If real-time posture feedback is provided through multiple analysis units, then exercise effectiveness is improved, but computational requirements and processing time increase
Solution Approach 1:
The system pre-establishes the assessment framework with dedicated arithmetic units for angle and center of gravity calculations, and analysis units for limb and balance assessment. This preliminary structuring enables efficient real-time processing during exercise execution, improving effectiveness without excessive processing delays
