Double-System Lock Control Piece Set for Key Combination Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of managing working elements between key locks and combination locks in double-system lock apparatuses makes them difficult to design and use effectively, especially when users need to switch between key and combination locking methods.
Innovation Solution
A double-system lock apparatus with a simplified structure, featuring a lock outer case, combination lock with rotating discs and coupling springs, key lock with a lock cylinder and sleeve set, and a control piece set that includes first, second, and third control pieces to facilitate easy switching between key and combination locking methods, ensuring convenience and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a double-system lock apparatus combines key lock and combination lock, then security and convenience are improved, but device complexity increases
Solution Approach 1:
The patent combines key lock and combination lock into a single integrated lock body, where both locking systems share common structural elements such as the lock body, locking bolt, and control mechanisms. This merging approach maintains dual-functionality while reducing overall structural complexity compared to having separate lock systems.
Solution Approach 2:
The lock apparatus is designed with multi-functional components that serve both key lock and combination lock operations. For example, the locking bolt and spring mechanism are shared between both systems, allowing a single structure to perform multiple locking functions, thereby improving security without proportionally increasing complexity.
2Ease of operation
If a double-system lock apparatus combines key lock and combination lock, then convenience for users is improved, but ease of operation deteriorates
Solution Approach 1:
The control mechanism is segmented into distinct control pieces - a key control piece for key lock operations and a dial control piece for combination lock operations. This segmentation allows users to operate each locking system independently and clearly, simplifying the user experience despite the integrated structure.
Solution Approach 2:
The patent introduces control pieces as intermediary elements that mediate between the user and the locking mechanisms. The key control piece receives key insertion and the dial control piece receives dialing inputs, translating these into corresponding locking/unlocking actions. This intermediary layer simplifies operation by providing clear, dedicated interfaces for each locking method.

AI summary
A double system lock apparatus comprises a lock shell, a combination lock, a key lock, and a control piece set. The lock shell has a panel and a main base assembled with each other. The combination lock has a plurality of rotating discs, coupling springs, couplings, and a shaft. The key lock has a lock cylinder and a sleeve set. From back to front, the control piece set has a first control piece, a second control piece, and a third control piece. By means of the control piece set working between the combination lock and the key lock, a double system lock apparatus of simple structure but well function has been formed.
