Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a distance measuring device is used to accurately detect the position of the battery swap apparatus, then the position detection precision is improved, but the device complexity increases
Solution Approach 1:
The patent combines the distance measuring device with the existing power transmission device (motor and encoder) into an integrated positioning system. The encoder from the power transmission device is utilized to measure the actual movement distance of the battery swap apparatus, merging the measurement function with the existing drive system rather than adding a completely separate measurement system.
Solution Approach 2:
The encoder, which is already part of the power transmission device, is made to serve dual purposes: controlling the motor and simultaneously measuring the actual position of the battery swap apparatus. This self-service approach allows the existing component to provide measurement functionality without requiring additional dedicated measurement hardware.
2Reliability
If the battery swap apparatus moves to an accurate position through precise detection, then the safety of the battery swap process is improved, but the energy consumption increases due to additional measurement operations
Solution Approach 1:
The patent implements a feedback mechanism where the encoder continuously monitors the actual position of the battery swap apparatus and compares it with the target position. This feedback loop allows the system to make precise adjustments only when necessary, rather than continuously operating at full power, thereby reducing overall energy consumption while maintaining safety.
Solution Approach 2:
The patent replaces continuous mechanical measurement methods with an electronic encoder-based measurement system. The encoder provides digital signals that can be processed efficiently by the control unit, reducing the energy required for position detection compared to traditional mechanical measurement approaches.
3Measurement precision
If the battery swap apparatus uses both distance measuring device and power transmission device for position detection, then the position detection precision is improved, but the device complexity increases
Solution Approach 1:
The control unit is designed to handle multiple functions: it controls the motor operation, processes encoder signals for position measurement, compares measured positions with target positions, and makes corrective decisions. This multi-functional design eliminates the need for separate dedicated control components for each function, reducing overall system complexity despite the enhanced measurement capabilities.
