Tilting Cable Clamp with Dual-Side Locking Claws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clamps are unsuitable for situations where the cable diameter is significantly smaller than the through hole diameter, as they cannot effectively clamp the cable and lock to the edges of the hole simultaneously.
Innovation Solution
A cable clamp design featuring a first and second element with retainer devices that allow the elements to be tilted for insertion into a through hole, then locked in place with claws on either side, ensuring the cable is clamped between the elements and secured to the hole edges, using separate clamping parts and flexible materials for enhanced grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cable clamp uses a conventional design with separate clamping and locking functions, then the structure is simple, but it cannot simultaneously clamp small-diameter cables and lock to the edges of large through holes
Solution Approach 1:
The cable clamp is divided into a first element and a second element that can be tilted relative to each other. The first element includes claws for locking to hole edges, while the second element provides clamping force. This segmentation allows independent optimization of locking and clamping functions, enabling the device to handle both small-diameter cables and large through holes effectively.
Solution Approach 2:
The cable clamp incorporates a tilting mechanism between the first and second elements, allowing dynamic adjustment of the clamping surface orientation. This dynamic capability enables the clamp to adapt to different cable diameters and through hole sizes, providing versatility without requiring multiple specialized devices.
2Reliability
If the cable clamp is designed to lock to the edges of the through hole, then strain relief is improved, but the ability to clamp small-diameter cables is compromised
Solution Approach 1:
The first element is equipped with claws specifically designed for locking to the edges of through holes, providing reliable strain relief. The second element features a clamping surface optimized for contacting and clamping small-diameter cables. This local specialization of functions ensures both locking reliability and clamping effectiveness for small cables are achieved simultaneously.
3Strength
If the first and second elements are kept in a fixed mutual position, then the clamping force is stable, but the insertion into the through hole becomes difficult
Solution Approach 1:
The cable clamp allows the first and second elements to be tilted relative to each other during insertion, reducing the effective profile and facilitating passage through the hole. Once inserted, the elements are locked into a fixed mutual position to provide stable and reliable clamping force. This dynamic-to-static transition resolves the contradiction between ease of insertion and clamping stability.
Solution Approach 2:
The tilting capability is provided as a preliminary action that enables easy insertion before the final clamping operation. The elements are temporarily positioned in a tilted state for insertion, then transitioned to the fixed clamping position, separating the insertion and clamping actions in time.

AI summary
A cable clamp for clamping a cable with respect to a through hole of a solid object is presented. The cable clamp includes first and second elements (102, 103) and retainer devices (105) for keeping the first and second elements with respect to each other so that the cable gets clamped between the first and second elements and the cable clamp gets locked to the edges of the through hole with the aid of first claws extending over the edges of the through hole on a first side of the solid object and with the aid of second claws capable of extending over the edges of the through hole on the second side of the solid object. The cable clamp can be inserted into the through hole when the first and second elements are tilted with respect to each other so that the first claws are nearer to each other.
