Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional double-lock mechanism with dead bolt design is used, then safety and reliability are improved, but the structure becomes complex, occupies large space, and response speed decreases
Solution Approach 1:
The patent extracts and eliminates the dead bolt component from the traditional double-lock mechanism, retaining only the essential limiting function through a simplified bolt design that moves directly between extended and retracted positions without the intermediate dead bolt element, thereby simplifying the structure while maintaining reliability
Solution Approach 2:
The lock mechanism is segmented into distinct functional components: the bolt for primary locking, the limiting mechanism for position control, and the actuator for operation. This segmentation allows each component to be optimized independently, reducing overall structural complexity while preserving the double-lock functionality
2Reliability
If a traditional double-lock mechanism with dead bolt design is used, then safety is improved, but the response speed decreases
Solution Approach 1:
By removing the dead bolt component, the patent eliminates the additional mechanical steps required for engagement and disengagement, allowing the bolt to transition directly between locked and unlocked positions, thereby significantly improving response speed while maintaining safety through the limiting mechanism
3Device complexity
If the bolt is directly connected to the lock cylinder, then the locking function is simple, but collision damage occurs to the lock cylinder due to bumps or vibrations in moving occasions
Solution Approach 1:
The patent introduces a limiting mechanism that acts as an intermediary between the bolt and the lock cylinder. This limiting mechanism includes a limiting member that physically restricts the bolt's movement range, preventing the bolt from colliding with the lock cylinder during vehicle bumps or vibrations, thereby protecting the lock cylinder while maintaining the simplicity of the direct connection
4Reliability
If the double-lock member is arranged on the side surface of the locking rod moving position, then the double-lock function is achieved, but the member collides with the locking rod during vehicle bumps and is damaged
Solution Approach 1:
The patent removes the separate double-lock member that was previously arranged on the side surface of the locking rod. Instead, the double-lock function is achieved through the integrated limiting mechanism that controls the bolt's movement, eliminating the collision-prone side-mounted member while preserving the double-lock functionality
Solution Approach 2:
The patent merges the double-lock function into the primary bolt limiting mechanism. The limiting member serves dual purposes: it limits the bolt's retraction to prevent unauthorized opening and simultaneously prevents forward collision during vehicle movement, combining multiple protective functions into a single integrated component that eliminates the need for separate side-mounted members

Function Achieved in This Case
The solution simplifies the lock structure, improves reliability and safety by preventing collision damage, and introduces electrical unlocking for enhanced convenience and intelligence, suitable for recreational vehicles.
Implementation Method 1
two load-bearing ends of the locking spring are respectively abutted against the lock body and the bolt, to drive the bolt to extend outwards by a length through a lock hole provided in one side of the lock body
Implementation Method 2
an electrical unlocking mechanism, which includes an unlocking motor and gear set

AI summary
A single-bolt lock structure and a recreational vehicle lock are provided, which relate to the technical field of locks for vehicles. The single-bolt lock structure includes a lock body. The lock body is provided with a bolt, a locking spring, a door opening handle, and a double-lock mechanism. The locking spring drives the bolt to lock a door. The door opening handle drives the bolt to open the door. The double-lock mechanism performs a limiting and locking operation on the bolt, thus achieving a double-lock effect on the lock body. Since a double-lock base and a locking rod cooperate with a latch bolt, existing problems are solved. By introducing an electrical unlocking mechanism and an electronic module, safety, convenience, and intelligence of the lock are further improved.
