Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical actuators are used to move the second member relative to the first member in the rider posture changing device, then the posture adjustment capability is improved, but the reliability of determining the actuation state deteriorates due to lack of effective detection methods
Solution Approach 1:
The patent implements feedback by detecting electrical-load information (current, voltage, power, or temperature) from the electrical actuator and using this information to evaluate the actuation state. The controller receives feedback signals from the detector and adjusts control accordingly, enabling reliable determination of whether the actuator is operating normally or in an abnormal state.
Solution Approach 2:
The patent replaces mechanical detection methods with electrical detection methods. Instead of using mechanical sensors to detect actuator state, the system uses electrical detectors to monitor electrical-load information, which provides more reliable and easier-to-implement state determination for electrical actuators.
2Reliability
If the controller continuously monitors electrical-load information to evaluate actuation states, then the reliability of abnormal state detection is improved, but the energy consumption increases
Solution Approach 1:
The patent monitors changes in electrical parameters (current, voltage, power, or temperature) of the actuator to detect abnormal states. By tracking parameter variations rather than continuously measuring all parameters at full resolution, the system achieves reliable detection while reducing overall energy consumption compared to continuous high-precision monitoring.
3Measurement precision
If the system evaluates actuation states based on multiple parameters including electrical-load information and movement distance, then the measurement precision of actuation state is improved, but the device complexity increases
Solution Approach 1:
The patent uses a single controller that performs multiple functions: it controls the electrical actuator, receives and processes electrical-load information from the detector, evaluates actuation states, and determines abnormal conditions. This multi-functional approach improves measurement precision through comprehensive monitoring while avoiding the need for separate dedicated components for each function, thereby limiting the increase in device complexity.
