Core Replaceable Hockey Lock With Universal Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hockey locks require different keys for various types and have non-standard cores, leading to user confusion, increased key management time, and economic burdens due to the need for multiple locks and stockpiling of cores, as well as the requirement for entire assemblies to be replaced if a core is damaged.
Innovation Solution
A core replaceable hockey lock design featuring a housing with an installation hole and slit, a rotatable deadbolt with passive members, a positioning plate, and a positioning pin, allowing for the use of different cores with a single key, enabling easy core replacement without replacing the entire lock assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different types of cores are used for different hockey locks, then the safety level and anti-theft feature are improved, but the outer contour of the core must be matched with the connection hole shape, restricting core replacement and requiring multiple keys
Solution Approach 1:
The hockey lock is divided into separate functional modules: the housing with connection hole, the core with standardized interface, and the deadbolt mechanism. This segmentation allows the core to be independently replaced without affecting the housing structure, enabling different core types to be used while maintaining compatibility.
Solution Approach 2:
A standardized connection interface is designed between the core and housing, allowing various core types (different shapes and functions) to be universally installed in the same housing. This universal interface enables one housing to accommodate multiple core types with different safety features and anti-theft capabilities.
2Device complexity
If the deadbolt and core are fixed to each other, then the locking mechanism is simple, but the core cannot be replaced independently, requiring entire assembly replacement
Solution Approach 1:
The locking mechanism is segmented into independently replaceable components: the core, the deadbolt, and the housing. The core connects to the deadbolt through a standardized interface that allows disassembly, enabling independent replacement of the core without affecting the deadbolt or housing.
Solution Approach 2:
The connection between the core and deadbolt is designed to be dynamically adjustable, allowing the core to be detached and reattached as needed. This dynamic connection enables easy core replacement while maintaining the simplicity of the overall locking mechanism during normal operation.
3Reliability
If multiple hockey locks are purchased for different locations, then the security coverage is improved, but the users have to carry multiple keys and manage them confusingly
Solution Approach 1:
The housing is designed with a universal connection interface that can accommodate different core types. This allows the same housing to be used in multiple locations with different core configurations, enabling a single key to operate multiple hockey locks while maintaining security coverage.
Solution Approach 2:
Multiple hockey lock systems are merged into a unified key management system by using the same housing design and connection interface across all locations. This merging allows different cores (with different security features) to be operated by a single key, simplifying key management while maintaining comprehensive security coverage.
4Reliability
If the entire hockey lock assembly is replaced when the core is damaged, then the reliability is maintained, but the economic burden increases due to waste and loss
Solution Approach 1:
The hockey lock assembly is segmented into replaceable modules: the housing, the core, and the deadbolt. When the core is damaged, only the core needs to be replaced while the housing and deadbolt remain functional, reducing material waste and economic loss compared to replacing the entire assembly.
Solution Approach 2:
The standardized connection interface enables selective replacement of only the damaged core component while recovering and reusing the intact housing and deadbolt. This approach minimizes material waste and reduces economic loss by retaining functional components rather than discarding the entire assembly.

AI summary
A core replaceable hockey lock includes a housing having a space defined therein. An installation hole is defined in one end thereof and a slit is defined in the inner periphery of the installation hole. An insertion hole is defined in the housing and communicates with the slit. A deadbolt is rotatably installed in the installation hole and has a recess which is located corresponding to the slit. The deadbolt has at least one passive member connected thereto which is located in one end of the housing. A positioning plate is inserted in the slit and the recess to axially position the deadbolt. A positioning pin is inserted into the insertion hole and positions the positioning plate. The hockey lock can use different cores installed therein such as six-bead core, seven-bead core or bead-replaceable core. The user needs only one key to unlock all of the hockey locks.
