Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard contact unlocking method is used between replacement device and battery case locking mechanism, then unlocking function can be achieved, but component wear increases and unlocking accuracy deteriorates
Solution Approach 1:
The patent introduces a magnetic field as an intermediary between the replacement device and the battery case locking mechanism. The mounting plate contains a magnet that magnetically attracts the locking tongue, enabling non-contact unlocking. This eliminates direct hard contact between components, reducing wear while maintaining reliable unlocking function.
2Stability of the object's composition
If separate locking mechanisms are used on both sides of battery case, then locking stability is improved, but alignment complexity increases and unlocking accuracy decreases
Solution Approach 1:
The patent combines two separate locking mechanisms into a single integrated locking structure. The battery case has one locking tongue that interacts with two locking grooves on the holder through magnetic attraction. This merging approach maintains the stability of dual-point locking while eliminating alignment complexity and improving unlocking accuracy.
3Measurement precision
If complex linkage transmission mechanism is used for precise unlocking control, then unlocking accuracy is improved, but device structure becomes more complex
Solution Approach 1:
The patent replaces complex mechanical linkage transmission mechanisms with a magnetic field-based locking and unlocking system. The magnet in the mounting plate directly actuates the locking tongue through magnetic attraction without requiring intermediate mechanical linkages, achieving precise unlocking control while simplifying the overall device structure.
