Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical braking system is used, then braking performance is improved, but reliability deteriorates when electrical system fails
Solution Approach 1:
The braking system dynamically switches between electrical braking mode and mechanical braking mode based on the operational status of the electrical system. The braking mode selection component can move between first and second positions to engage different transmission portions, enabling the system to adapt its braking mode in real-time according to system conditions, thereby maintaining reliability while preserving adaptability.
2Measurement precision
If driver is always powered on, then braking control precision is improved, but overheating risk increases
Solution Approach 1:
The driver operates periodically rather than continuously. The system switches between electrical braking mode (when driver is powered on) and mechanical braking mode (when driver is powered off), allowing the driver to rest and cool down periodically. This periodic operation maintains braking control precision when needed while preventing overheating through scheduled idle periods.
3Ease of operation
If manual switching operation is required, then ease of operation deteriorates, but device complexity is reduced
Solution Approach 1:
The braking system performs self-service by automatically detecting the operational status of the electrical system and autonomously switching between braking modes without requiring manual intervention. The braking mode selection component and transmission member work together to automatically engage the appropriate transmission portion, eliminating the need for manual switching operations while managing the necessary complexity through automated control.

AI summary
A braking mode switching apparatus includes a braking mode selection component, a transmission member, a stopper, a driver, and a motion control component. The braking mode selection component can move between a first position corresponding to a first braking mode and a second position corresponding to a second braking mode. The transmission member has a first transmission portion and a second transmission portion. The stopper includes a first stopper portion and a second stopper portion. The motion control component is configured to abut against the first stopper portion in response to a case in which the driver is powered on, where the braking mode selection component is located in the first position; and abut against the second stopper portion in response to a case in which the driver is not powered on, where the braking mode selection component is located in the second position.
