Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional door locks use multiple separate components, then the structure is easier to manufacture, but the operational reliability deteriorates over time due to wear and tear
Solution Approach 1:
The patent merges multiple separate components into an integrally formed body with integrated cap structures. The first and second caps are formed as integral parts of the main body, eliminating separate assembly points and reducing the number of components. This integration reduces wear and tear at connection points while maintaining manufacturing feasibility through integral forming processes.
2Strength
If the deadbolt is made from conventional single-piece structure, then the manufacturing is simpler, but the structural strength deteriorates when subjected to impact forces
Solution Approach 1:
The patent employs a composite structural design where the body incorporates integrated cap structures (first cap and second cap) that are formed as integral parts. This composite approach creates a multi-material or multi-density structure within the single piece, enhancing strength and impact resistance while maintaining manufacturing simplicity through integral forming processes.
3Ease of operation
If the door lock uses conventional connection methods, then the assembly is easier, but the operational smoothness deteriorates after extended use
Solution Approach 1:
The patent combines the body and cap structures into an integral formation, eliminating separate connection interfaces that would otherwise wear over time. This merging ensures that the operational surfaces remain smooth and consistent throughout the service life, as there are no separate components to degrade or misalign.

Function Achieved in This Case
The solution enables efficient and durable operation of the door lock by maintaining the deadbolt's structural integrity and ensuring smooth extension and retraction, enhancing the lock's longevity and functionality.
Implementation Method 1
a resilient element, a first end of the resilient element is positioned on the second positioning segment of the slide cylinder, and a second end of the resilient element is fixed on the first positioning segment of the deadbolt
