Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmission system uses fixed gear positions without dynamic adjustment, then the device complexity is reduced, but the adaptability to different running conditions deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the transmission route to change adaptively based on real-time bicycle information. The controller dynamically adjusts gear positions and transmission actions according to detected parameters such as cadence, torque, and geographical location, transforming a static transmission system into a dynamic one that responds to varying running conditions.
Solution Approach 2:
The patent implements feedback through bicycle-information obtaining devices that continuously detect running conditions and feed this information to the controller. The controller uses this feedback to automatically adjust the transmission route, creating a closed-loop control system that adapts to changing conditions without requiring manual intervention from the rider.
2Productivity
If the system automatically adjusts transmission route based on multiple parameters, then the productivity and efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional transmission apparatus that integrates multiple detection functions (cadence detection, torque detection, geographical location detection) and control functions into a single system. The controller serves multiple purposes by processing various types of bicycle information and generating appropriate transmission actions, reducing the need for separate specialized components.
Solution Approach 2:
The patent implements self-service through the automatic transmission route adjustment capability. The system monitors its own operating conditions and autonomously makes transmission decisions without requiring external input or manual shifting by the rider. This self-regulating mechanism improves shifting efficiency and allows the rider to focus on pedaling while the system optimizes gear selection independently.
3Adaptability or versatility
If the transmission system considers multiple bicycle information parameters, then the adaptability improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent applies segmentation by dividing the information detection task into separate specialized sensors: a cadence detection device for measuring pedal rotation speed, a torque detection device for measuring applied force, and a geographical location detection device for determining position and terrain. Each sensor is optimized for its specific measurement function, reducing the complexity that would arise from attempting to measure all parameters with a single device.
