Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or bolts are used to fasten the keeper on the shaft, then the keeper is securely fixed, but the installation and adjustment process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the traditional screw or bolt fastening mechanism with a spring-loaded retaining member system. The retaining member, driven by elastic force from a compression spring, pushes against the keeper to secure it on the shaft without requiring threaded fasteners. This mechanical substitution eliminates the need for screws or bolts while maintaining secure fixation, thereby reducing installation and adjustment time.
Solution Approach 2:
The spring-loaded retaining member system is designed to be self-adjusting and self-securing. When the keeper is positioned on the shaft, the compression spring automatically pushes the retaining member to engage with the keeper, securing it in place without requiring additional fastening operations. This self-service mechanism eliminates the manual intervention needed for screw tightening or bolt fastening, significantly reducing adjustment time while ensuring reliable fixation.
2Adaptability or versatility
If the keeper position on the shaft needs to be adjusted, then the locking or unlocking function can be modified, but the adjustment steps become cumbersome and time-consuming
Solution Approach 1:
The patent replaces the screw or bolt fastening mechanism with a spring-loaded retaining member system that allows the keeper to be easily slid along the shaft. The elastic force from the compression spring continuously pushes the retaining member against the keeper, maintaining secure engagement during movement. This enables smooth repositioning of the keeper to adjust locking or unlocking functions without the cumbersome steps of loosening and tightening fasteners, significantly improving adjustment ease while maintaining position adaptability.
3Ease of operation
If a holding assembly with elastic member is used to hold the keeper, then the adjustment process is simplified, but the structure becomes more complex
Solution Approach 1:
The patent merges the holding function and the adjustment facilitation into a single integrated spring-loaded retaining member system. The compression spring provides continuous elastic force that both secures the keeper on the shaft and enables easy repositioning. By combining these functions into one mechanism rather than separate components, the patent reduces overall structural complexity while improving adjustment ease compared to traditional screw or bolt systems that would require additional washers, nuts, or adjustment mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and efficient adjustment of the keeper's position on the shaft, improving installation efficiency and ease of switching between locking and unlocking states.
Implementation Method 1
a first elastic member connected between the retaining member and the fixing member. The fixing member is used to fix the first elastic member to the keeper. In the restricted state, the first elastic member is compressed to drive the retaining member to be held on the shaft.
Implementation Method 2
the shaft is also provided with a second elastic member. One end of the shaft is provided with a restrictor component, and both ends of the second elastic member are connected to the restrictor component as well as to the lock body respectively. In an energized state, the second elastic member is in a compressed state. In a de-energized state, the second elastic member drives the stopping device as well as the spindle to return to the original position.
Implementation Method 3
the electric drive device comprises a solenoid and a spindle. In an energized state, the solenoid generates a magnetic force to attract the spindle to move, and the spindle pushes the stopping device to move during movement, to drive the keeper to switch between the locking position and the unlocking position.

AI summary
The present invention discloses an electric strike which includes a lock body, a latch and a stopping device. The latch is rotatably connected to the lock body. The stopping device is mounted on the lock body. The stopping device comprises a shaft, a keeper and a holding assembly for holding the keeper on the shaft. The holding assembly comprises a retaining member, a fixing member fixedly mounted on the keeper, and a first elastic member connected between the retaining member and the fixing member. The fixing member is used to fix the first elastic member to the keeper. In the restricted state, the first elastic member is compressed to drive the retaining member to hold on the shaft. The keeper in the electric strike of the present invention can be securely mounted on the shaft, and it is easy to adjust the relative position of the keeper on the shaft.
