Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed actuator type (mechanical or electric) is used in the rider-posture changing assembly, then the structure is simple and reliable, but the adaptability to different riding conditions and control preferences is limited
Solution Approach 1:
The actuator receiving part is designed with a universal interface that can interchangeably receive both mechanical actuators and electric actuators. The connecting portions are configured to engage with the actuator receiving part in a standardized manner, allowing the same receiver to accommodate different actuator types without requiring separate mounting structures for each actuator type.
Solution Approach 2:
The system allows dynamic switching between mechanical and electric actuators based on riding conditions and user preferences. The interchangeable design enables the actuator configuration to be changed during the vehicle's operational life, transforming a static system into a dynamic one that can adapt to varying requirements.
2Ease of operation
If an electric actuator is used for automatic rider posture adjustment, then the ease of operation is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system allows replacement of mechanical actuation mechanisms with electric actuators for automatic rider posture adjustment. The electric actuator receives the same mechanical interface as a mechanical actuator would, enabling substitution of manual mechanical control with automated electric control while maintaining compatibility with the existing state-changing structure.
Solution Approach 2:
The interchangeable actuator design enables the system to serve itself by allowing easy replacement and reconfiguration of actuators based on operational needs. The standardized interface allows the system to maintain functionality while adapting to different control methods without requiring complex reengineering.
3Ease of manufacture
If a mechanical actuator is used for rider posture adjustment, then the ease of manufacture and reliability are improved, but the ease of operation for dynamic adjustment is reduced
Solution Approach 1:
The system provides the option to replace manual mechanical actuators with electric actuators when ease of operation becomes a priority. The interchangeable interface allows users to swap from simple mechanical actuators to electric ones without changing the mounting structure, enabling transition from manual to automated control based on operational requirements.

AI summary
A rider-posture changing assembly basically includes a first member, a second member and a state-changing structure. The first member has an actuator receiving part configured to interchangeably receive one of a mechanical actuator and an electric actuator at a time. The mechanical actuator and the electric actuator each has a connecting portion configured to engage with the actuator receiving part. The connecting portions of the mechanical actuator and the electric actuator are similar to each other. The first and second members are relatively movable in a longitudinal direction. The state-changing structure is configured to change the state of the rider-posture changing assembly between a first state and a second state. The first and second members are restricted from moving relative to each other in the first state. The first and second members are relatively movable in the longitudinal direction in the second state.
