Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional battery fitting sets use multiple auxiliary structures for secure locking, then reliability of battery installation is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple auxiliary structures (resilient member, self-locking block, stoppers) into an integrated fitting set that works together as a unified system. The resilient member integrates both the locking function and the guiding function, while the self-locking block combines the blocking function with the locking mechanism, reducing the need for separate components.
Solution Approach 2:
The self-locking block automatically locks into the resilient member when the battery is properly inserted, without requiring manual operation. The resilient member automatically engages with the self-locking block through elastic deformation, creating a self-securing mechanism that ensures reliable installation without complex manual procedures.
2Reliability
If conventional battery fitting sets include multiple auxiliary structures for orientation control, then reliability of battery orientation is improved, but ease of operation deteriorates due to multiple steps required
Solution Approach 1:
The fitting set uses asymmetric features including the positioned stoppers at specific locations on the resilient member and the corresponding asymmetric shape of the self-locking block. This asymmetric design ensures that the battery can only be inserted in the correct orientation, as reverse insertion would not allow the self-locking block to engage with the stoppers properly.
Solution Approach 2:
The resilient member is pre-configured with stoppers at specific positions that guide the self-locking block into the correct orientation before engagement. The pre-positioned stoppers create a guiding path that automatically orients the battery correctly during insertion, eliminating the need for manual orientation adjustments.
3Reliability
If conventional battery fitting sets use complex auxiliary structures, then secure locking is achieved, but productivity deteriorates due to multiple steps for battery exchange
Solution Approach 1:
The self-locking block automatically locks into the resilient member upon insertion and can be automatically released by applying force to the resilient member, enabling single-handed operation. This self-service mechanism eliminates the need for multiple manual steps such as opening covers or manually disengaging locking mechanisms, significantly speeding up battery exchange while maintaining secure locking.
Solution Approach 2:
The resilient member provides dynamic locking through elastic deformation, allowing the self-locking block to engage smoothly during insertion and be easily released by overcoming the elastic force. This dynamic mechanism enables rapid battery exchange while ensuring secure locking during operation, as the resilient member maintains constant locking pressure without requiring manual intervention.

AI summary
A fitting set, including a battery assembly and a receiver having a recess for receiving the battery assembly are disclosed. The battery assembly may include a casing having a top wall, a bottom wall, two first sidewalls, and two second sidewalls. The battery assembly may further include a resilient member and a self-locking block. The first sidewalls may include notches extending to the bottom wall. The recess may include lugs on one or more of the inners walls, each of which may be engaged with a corresponding notch. The second sidewalls may each include a first stopper and one or more second stoppers, the first and second stoppers having a difference in height. The resilient member at both ends may abut against the first stopper and self-locking block, respectively, and may also press the self-locking block against an edge of the recess.
