Core Replaceable Hockey Lock with Removable Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hockey locks do not allow core replacement, leading to the need for multiple locks and keys for different doors, increased expenses due to whole lock replacement when the core is damaged, and lack of visibility for key insertion, which complicates locking and unlocking.
Innovation Solution
A core replaceable hockey lock design featuring a first and second end face with specific cavities and a core hole, where the core can be easily removed and replaced, with a locking mechanism that allows the shackle to be unlocked and a cover that protects the core and keyhole, enabling the same core to be used across different locks and reducing the need for multiple keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the core is secured to the shackle and cannot be separated, then the lock structure is simple and reliable, but the users cannot replace the core when needed and have to purchase multiple locks for different doors
Solution Approach 1:
The lock body is divided into separable components: a removable cover that provides access to the core, and a core that can be independently removed and replaced. The cover is detached by pulling it away from the lock body, exposing the core hole where the core can be accessed, removed, and replaced without affecting the shackle or lock body structure.
Solution Approach 2:
The core is extracted as a separate, replaceable component from the lock system. The core can be removed from the core hole through the cover opening and replaced with a different core, allowing the same lock body to be used with different cores for different doors or security requirements.
2Ease of operation
If the core is located at the periphery of the lock, then the lock structure is compact, but the users cannot see the keyhole and core directly, requiring multiple attempts to insert the key
Solution Approach 1:
The cover is preliminarily positioned to cover and protect the core and keyhole when not in use. When key insertion is needed, the cover is pulled away from the lock body in advance to expose the core hole and keyhole, allowing the user to see and access them directly without multiple attempts.
3Ease of repair
If the core is damaged, then the lock must be replaced with a new one, but this increases expenses
Solution Approach 1:
When the core is damaged, only the core itself is discarded and replaced, while the lock body, shackle, and cover are recovered and reused. The cover is removed to access the core hole, the damaged core is taken out, and a new core is inserted, allowing repair without replacing the entire lock assembly.
4Adaptability or versatility
If multiple locks with different cores are purchased for different doors, then each door can be secured independently, but the users need to carry multiple keys and expenses increase
Solution Approach 1:
The same lock body with interchangeable cores can serve multiple doors or security applications. By keeping the lock body and shackle and only replacing the core, a single lock design can be adapted for different doors, reducing the need for multiple complete lock sets and multiple keys.

AI summary
A core replaceable hockey lock includes a first end face and a second end face. The first end face includes a first cavity, a second cavity, a third cavity and a fourth cavity. The end face includes a core hole which communicates with the second cavity. A lateral hole is defined radially in the lock and communicates with the first and fourth cavities. A locking member is located in the second cavity and includes a connection portion connected to the transmission portion, and a stop plate which slides in the third cavity when the locking member is rotated. A locking part is located in the fourth cavity. A shackle is located in the lateral hole and includes a neck located corresponding to the fourth cavity and the locking part. The first cavity and the core hole are parallel to each other. The core is replaceable by removing the cover.
