Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional exercise monitoring methods are used, then basic exercise data can be collected, but accurate assessment of arm swing degree is not achieved
Solution Approach 1:
The patent implements a feedback mechanism where the degree of arm swing is measured using motion sensors, compared against target values, and feedback information is provided to the user through display or audio output. This closed-loop feedback system enables accurate assessment and guidance of arm swing degree during exercise, resolving the contradiction between measurement precision and information completeness.
Solution Approach 2:
The patent replaces conventional mechanical or manual exercise monitoring methods with electronic motion sensors and computational analysis. By using acceleration sensors and angular velocity sensors to detect motion data, the system achieves precise measurement of arm swing degree without relying on subjective assessment or simple mechanical counters, thereby improving measurement precision while capturing comprehensive exercise motion status.
2Productivity
If arm swing monitoring is added to exercise tracking, then exercise efficiency can be improved, but device complexity increases
Solution Approach 1:
The patent employs motion sensors that serve multiple functions: they detect both the degree of arm swing and the type of exercise being performed. By processing the same sensor data through different algorithms, the system extracts multiple exercise parameters without requiring separate dedicated sensors for each measurement, thereby improving exercise efficiency assessment while limiting the increase in device complexity.
Solution Approach 2:
The system automatically processes motion data to calculate arm swing degree and provides feedback without requiring manual intervention or complex user setup. The processing section automatically identifies exercise types, calculates swing angles, and generates feedback information, making the enhanced monitoring capability accessible through a simple interface and reducing the perceived complexity for users.

AI summary
An exercise support device of the present invention includes a detecting section which detects motion data related to a motion status of a user performing an exercise and an swing-angle obtaining section which obtains an swing angle of the user and an information notifying section which notifies the user of exercise support information for guiding the swing angle to a suitable angle. When the user is in a specific motion state with an swing motion of a part which is an arm or a leg of the user, the swing-angle obtaining section successively tracks a swing status in one cycle of the swing motion in the specific motion state based on the motion data detected by the detecting section, and obtains a maximum value of differences between angles of the part of the user at two different timings in the one cycle as the swing angle.
