Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resistance bands or pneumatic cylinders are used for exercise, then exercise flexibility and portability are improved, but measurement precision of force and repetitions deteriorates
Solution Approach 1:
The patent replaces traditional mechanical measurement systems with electronic sensors. Force sensors (load cells) and acceleration sensors (gyroscopes) are integrated into the resistance band handles to electronically measure force vectors, repetition counts, and motion dynamics, providing precise digital data without compromising the flexibility of resistance band exercise
Solution Approach 2:
The patent introduces a microprocessor-based control system as an intermediary between the mechanical exercise components and the measurement function. The microprocessor receives data from force sensors and acceleration sensors, processes the information, and provides feedback through displays or wireless communication, enabling accurate measurement while maintaining exercise flexibility
2Device complexity
If traditional resistance bands are used, then device complexity is reduced, but loss of information regarding force and repetition tracking increases
Solution Approach 1:
The patent merges multiple functions into the resistance band system: force measurement, repetition counting, exercise form monitoring, and progress tracking are all integrated into a single system. The force sensor, acceleration sensor, and microprocessor work together as unified components within the handle assembly, providing comprehensive data collection without significantly increasing overall system complexity
Solution Approach 2:
The system automatically performs measurement, calculation, and tracking functions without requiring user intervention. The microprocessor automatically counts repetitions based on sensor data, calculates force metrics, and stores progress information, eliminating the need for manual logging and reducing information loss while keeping the interface simple
