Core-Replaceable Hockey Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hockey locks are inconvenient due to the core's peripheral location, requiring users to carry multiple keys and necessitating entire lock replacement when the core is damaged, as the core and engaging member are integrally formed.
Innovation Solution
A hockey lock design featuring a casing with a first recess and guide slot, allowing the core to be positioned between unlock and locked positions, with a mounting member and latch system that enables easy key access and core replacement without replacing the entire lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the core and engaging member are integrally formed, then the lock structure is simplified, but the entire lock must be replaced when the core is damaged
Solution Approach 1:
The lock is divided into separable components: the core (20) can be independently removed from the casing (10) through the accessible slot (101). The engaging member (202) remains in the casing while the core is replaceable, allowing core replacement without replacing the entire lock assembly.
Solution Approach 2:
The core (20) is extracted as a separate replaceable component from the integral structure. The core can be removed through the accessible slot (101) and replaced independently, while the engaging member (202) and casing (10) remain in place.
2Volume of moving object
If the core is located at the periphery of the casing, then the lock structure is compact, but the user has difficulty finding the orientation to insert the key
Solution Approach 1:
The lock hole (201) is provided with a guide mark (203) that visually indicates the correct orientation for key insertion. This allows users to quickly identify the proper key insertion angle without needing to search for the correct orientation.
3Reliability
If each hockey lock has its own integral core, then the lock security is maintained, but the user has to carry multiple keys for different locks
Solution Approach 1:
The core (20) is designed as a universal replaceable component that can be removed and transferred between different casings (10). Users can keep a single core and replace it in different locks, allowing one key to operate multiple locks while maintaining security through the intact engaging member (202) and casing (10) structure.

AI summary
A hockey lock includes a casing (1) having a first recess (11), a path (12) and a guide slot (13) which communicates with the first recess (11) and the path (12). A core (2) is located in a housing (21) which is located in the first recess (11). A mounting member (4) is connected to the core (2) and has a recessed portion (41) which is located corresponding to the guide slot (13) when the core (2) is at the unlocked position. A latch (6) extends through the path (12) and has a groove (61) which is located corresponding to the guide slot (13) when the core (2) is at the locked position. A pin (7) is received in the guide slot (13) and is pushed by the mounting member (4) to be engaged with the groove (61) when the core (2) is at the locked position. The pin (7) is inserted into the recessed portion (41) and disengaged from the groove (61) when the core (2) is at the locked position.
