Universal Lock Core for Multiple Key Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks require separate molds and inventory for different keyway shapes, leading to increased manufacturing and inventory costs, and limit the use of different keys with the same locking code to a single shape, causing inconvenience in key replacement and management.
Innovation Solution
A lock core device that accommodates multiple key cross-sectional shapes, featuring a keyway with adjustable edges and lock ball slots to align with various key contours, allowing easy replacement and management of keys with different section contours while maintaining stability and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the keyway is configured for a specific cross-sectional shape, then the lock provides anti-theft protection, but separate molds and inventory are required for different key shapes, increasing manufacturing and inventory costs
Solution Approach 1:
The keyway is designed with a universal structure that can accommodate multiple key cross-sectional shapes (S-shape, M-shape, X-shape, L-shape, K-shape, W-shape, Y-shape) through a single mold. The keyway includes a key receiving cavity with a bottom surface that can adapt to different key shapes, eliminating the need for separate molds for each key shape while maintaining anti-theft protection through the lock ball mechanism.
2Ease of operation
If the keyway is configured for a specific cross-sectional shape, then the lock core can be rotated to unlock, but different keys with the same locking code cannot be used, causing inconvenience
Solution Approach 1:
The keyway is designed to universally accept keys with different cross-sectional shapes while maintaining the same locking code functionality. The key receiving cavity's bottom surface is configured to adapt to various key shapes, allowing users to replace keys freely without being restricted to a single key shape, thus improving both ease of operation and adaptability.
Solution Approach 2:
The keyway structure incorporates local adaptability features, such as the bottom surface of the key receiving cavity, which is designed to accommodate different key shapes at specific locations. This local quality adjustment allows the lock to maintain its core functionality while adapting to various key shapes, enabling convenient key replacement.
3Manufacturing precision
If the teeth positions of keys with different cross-sectional profiles deviate, then the keys cannot correspond to the lock ball slots for unlocking, but the lock ball slots are fixed in position
Solution Approach 1:
The lock ball slots are designed with adjustable parameters, specifically their positions can be modified to correspond with the teeth of keys having different cross-sectional profiles. This parameter adjustment allows the lock ball slots to align with the teeth of various key shapes, ensuring that keys with different profiles can successfully unlock the lock while maintaining manufacturing precision.

AI summary
A lock core device based on matching the cross-sectional shape of a multiple key and a corresponding lock key, the lock contains a keyway, and the outer contour of the keyway is configured as a first section contour and a second section contour after superimposition, and its' a union outer contour. By adapting to existing keys with various cross-sectional profiles, the lock cylinder does not need to be manufactured separately according to the cross-sectional profile of the key, thus effectively reducing its manufacturing and inventory costs; A method for configuring a lock ball slot so that, in response to the deviation of the position of the teeth of the keys with different cross-sectional profiles, the teeth of the keys with different cross-sectional profiles can correspond to the lock ball slot for unlocking, thus ensuring stability and effectiveness during unlocking.
