Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wireless communicator and sensor circuit are integrated in a single housing, then the device structure is simplified, but the mounting flexibility and adaptability are reduced
Solution Approach 1:
The device is divided into two separate housings: a first housing containing the sensor circuit and a second housing containing the wireless communicator. This segmentation allows each component to be independently mounted and positioned, providing mounting flexibility while maintaining a relatively simple overall device structure.
2Measurement precision
If strain sensors are mounted directly on the crank arm, then the detection accuracy is improved, but the device complexity increases
Solution Approach 1:
A sensor circuit board serves as an intermediary between the strain sensors mounted on the crank arm and the wireless communicator. The sensor circuit processes signals from the strain sensors and transmits them wirelessly, improving detection accuracy while managing the complexity through functional separation.
3Reliability
If the sensor circuit is permanently mounted to the crank assembly, then the reliability is improved, but the ease of repair and replacement is reduced
Solution Approach 1:
The sensor circuit is housed in a separate first housing that can be detached from the crank assembly. This segmentation maintains reliable electrical connections during operation while enabling easy removal and replacement of the sensor circuit when needed, improving both reliability during use and ease of repair.

AI summary
A bicycle pedaling force detector is basically provided with that basically includes a first sensor circuit, a wireless communicator and a first electrical connection member. The first sensor circuit is coupled to a first housing that is configured to be mounted to a crank assembly. The wireless communicator is coupled to a second housing that is configured to be detachably mounted to a crank assembly. The second housing is a separate member from the first housing. The first electrical connection member is configured to electrically connect the wireless communicator and the first sensor circuit.
