Adjustable Cable Lock With Sliding Rod Sleeve for Secure Loop Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable locks have fixed cable lengths that cannot be adjusted, allowing articles to move during securing and are vulnerable to cutting, compromising their anti-theft effectiveness.
Innovation Solution
A lock with an adjustable cable mechanism featuring a lock base, rod sleeve, lock component, and fixed base, allowing the loop length to be adjusted and secured firmly using a buckle hole with inclined and vertical teeth, and a set of numbered rotary discs for locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable length is fixed, then the lock structure is simple, but the article cannot be securely fastened and remains movable
Solution Approach 1:
The cable length is made adjustable through a dynamic mechanism involving a rod sleeve that can slide within the lock body, allowing the cable length to be changed according to different securing needs. The rod sleeve contains multiple positioning holes that enable discrete length adjustments while maintaining structural integrity.
Solution Approach 2:
The lock structure is segmented into multiple functional components: lock body, rod sleeve, locking component, and cable assembly. This segmentation allows the cable length adjustment function to be independent while maintaining overall lock simplicity.
2Reliability
If the cable length is fixed, then the manufacturing is simple, but the anti-theft effectiveness is reduced due to gaps between cable and article
Solution Approach 1:
The adjustable cable length mechanism allows the lock to adapt to different article sizes, eliminating gaps between the cable and article that would otherwise reduce anti-theft effectiveness. The rod sleeve sliding mechanism enables precise length adjustment to fit various securing scenarios.
Solution Approach 2:
The cable length parameter can be changed according to different securing requirements. The rod sleeve contains multiple positioning holes at different positions, allowing the user to select and adjust the cable length to eliminate gaps and improve anti-theft effectiveness for different article sizes.
3Ease of operation
If the cable is movable during securing, then the lock is easy to operate, but the cable is vulnerable to cutting
Solution Approach 1:
The cable is designed to be movable during the securing process, allowing easy placement around articles. Once secured, the locking component with inclined and vertical surfaces engages with the rod sleeve to firmly fix the cable position, preventing movement that would make the cable vulnerable to cutting.
Solution Approach 2:
The locking component is designed to prevent cable movement that would lead to vulnerability. The inclined surface allows easy engagement, while the vertical surface prevents disengagement, creating a preliminary protective action that secures the cable in position before any cutting attempt can occur.

AI summary
A lock with adjustable cable includes a lock base having a notch with a radius respectively on two opposite outer walls of the lock base, a rod sleeve disposed with an insertion slot assembled in the lock base; a lock component including a cable fastening portion consisted of a buckle hole, a stuck teeth with an inclined surface on one literal side of the stuck teeth and a partially vertical surface on the other literal side of the stuck teeth, assembled in the rod sleeve, an arrow on outer surface of the cable fastening portion, a stopper at the other end of the cable fastening portion, a steel cable fixed on an outer side of the stopper, and a fixed base assembled on the lock base and the other end of the rod sleeve. The loop length of the cable can be adjusted per a target object.
