Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple accelerometers and angle sensors are used to improve measurement precision, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measurement system is divided into multiple independent sensor units (two-dimensional accelerometer, one-dimensional accelerometer, angle sensors) that each capture specific aspects of swing motion. This segmentation allows precise measurement of different motion parameters while keeping each individual sensor relatively simple.
Solution Approach 2:
The patent transitions from single-dimensional acceleration measurement to multi-dimensional measurement by combining two-dimensional accelerometers for horizontal plane detection with one-dimensional accelerometers and angle sensors for vertical plane and rotational detection, achieving comprehensive three-dimensional swing analysis.
2Productivity
If real-time feedback is provided to improve training efficiency, then productivity is improved, but use of energy increases
Solution Approach 1:
The system provides feedback in periodic cycles corresponding to swing repetitions rather than continuous monitoring. The measurement and feedback process is triggered periodically at the start of each swing cycle, reducing continuous energy consumption while maintaining training effectiveness.
Solution Approach 2:
The system compares measured swing parameters against target values and provides differential feedback to guide correction. This feedback mechanism enables efficient learning by highlighting specific deviations rather than requiring continuous complex processing, optimizing the balance between training effectiveness and energy use.
