Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users exercise alone without trainers, then exercise accessibility is improved, but posture accuracy and safety deteriorate
Solution Approach 1:
The exercise equipment automatically performs posture analysis and provides guidance without requiring external trainers. The system uses integrated sensors and processing units to monitor user posture, detect deviations, and deliver real-time feedback, enabling users to exercise independently while maintaining proper form.
Solution Approach 2:
The system continuously monitors exercise posture through sensors and provides real-time feedback to users. When posture deviations are detected, the system generates guidance information and displays it to the user, creating a closed-loop control system that helps users maintain correct posture throughout the exercise.
2Ease of operation
If generic exercise guidance is provided, then ease of use is improved, but measurement precision and personalization deteriorate
Solution Approach 1:
The system provides personalized posture guidance tailored to each user's specific characteristics, exercise type, and real-time posture data. Instead of generic guidance, the system adjusts its feedback based on individual measurements, making the exercise guidance both precise and easily understood for each user.
Solution Approach 2:
The system dynamically adjusts guidance parameters based on real-time posture measurements and exercise progress. It monitors multiple parameters such as joint angles, body position, and movement velocity, then modifies guidance recommendations accordingly, enabling precise personalization while maintaining ease of use through automated adaptation.
3Measurement precision
If multiple sensors are integrated for comprehensive monitoring, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensors (accelerometers, gyroscopes, position sensors) into a unified exercise equipment system with a centralized processing unit. By merging these components into a single integrated system rather than separate devices, the patent achieves comprehensive posture monitoring while managing complexity through consolidation and coordinated control.
