Hidden Shackle Lock KiK Cylinder Retention
Solution Overview
Problem
Incorporating a Key-in-Knob (KiK) cylinder into a hockey puck lock poses challenges as the sliding motion required for unlocking can cause the KiK cylinder to detach from the lock housing, making it difficult to maintain secure locking.
Innovation Solution
A hidden shackle style lock design featuring a cylindrical housing with intersecting cavities, a hollow sleeve, and a shackle assembly with a KiK lock cylinder, where the sleeve is slidably attached and secured using a retaining screw, allowing the shackle to rotate and engage with locking features without detaching from the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a KiK cylinder is incorporated into a hockey puck lock using sliding motion for operation, then the lock can utilize a commonly available standardized cylinder, but the KiK cylinder may detach from the lock housing during unlocking
Solution Approach 1:
The lock is divided into separate functional components: a hollow sleeve that receives the KiK cylinder, a retaining screw that secures the sleeve to the housing, and the KiK cylinder itself. This segmentation allows the KiK cylinder to be standardized and interchangeable while the sleeve and retaining mechanism provide secure attachment to the housing.
Solution Approach 2:
The hollow sleeve is pre-attached to the lock housing using a retaining screw before the KiK cylinder is installed. This preliminary attachment ensures that the sleeve remains fixed to the housing, preventing any detachment of the KiK cylinder during subsequent unlocking operations.
2Object-affected harmful factors
If the shackle is made hidden to prevent attacks, then security against cutting and torque attacks is improved, but the locking mechanism becomes more complex
Solution Approach 1:
The KiK cylinder is nested within the hollow sleeve, which itself is attached to the lock housing. The shackle is coupled to the KiK cylinder, creating a nested arrangement where compact internal components are housed within each other. This nesting reduces the overall external profile while maintaining functional complexity.
Solution Approach 2:
The hollow sleeve acts as an intermediary component between the KiK cylinder and the lock housing. It provides a interface that adapts the standardized KiK cylinder to the specific requirements of the hockey puck lock, simplifying the integration of standardized components into the hidden shackle design.

AI summary
A hidden shackle style lock is disclosed. The lock has a substantially cylindrical housing having a top surface, a bottom surface, and a curved side surface. The lock also has a first cavity on the bottom surface of the housing which extends part way along a thickness of the housing, and a second cavity on the side surface intersecting with the first cavity. The lock further includes has a hollow sleeve slidably attached within the second cavity. The sleeve has a first end face, a second end face, and a third cavity. The third cavity extends from the first end face to the second face and is substantially coaxial with the second cavity. A shackle is coupled to the first end face of the sleeve. A core member with a locking mechanism is disposed within the third cavity and coupled to the shackle. A driver member is located between the core member and the shackle and couples the core member to the shackle.
