Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clamps for telecommunication cables are difficult to use, require hand tools for adjustments, and are prone to falling apart, making them inefficient and unreliable for securing cables of varying sizes.
Innovation Solution
A one-piece cable clamp design with a top and bottom plate hinged together, made of forged steel, featuring rubber gaskets and a one-handed closing mechanism that securely holds cables of various diameters without needing tools, ensuring durability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If prior art cable clamps are made of lightweight sheet metal, then the clamps are easy to manufacture, but they fall apart quickly and lack durability
Solution Approach 1:
The cable clamp combines steel plates for structural strength and durability with rubber gaskets for cable protection and grip. This composite material approach resolves the contradiction by using materials that complement each other's properties rather than relying on a single material type.
Solution Approach 2:
The clamp is divided into separate functional components: steel plates for structural integrity, rubber gaskets for cable contact, and a closing mechanism for operation. This segmentation allows each component to be optimized for its specific function while working together as a unified system.
2Manufacturing precision
If prior art cable clamps require hand tools and wrenches for adjustments, then the clamps can be precisely adjusted to specific cable sizes, but they are difficult to use and require multiple tools
Solution Approach 1:
The closing mechanism transforms the static clamp structure into a dynamic system that can be easily opened and closed by hand. The lever arm and pivot point create mechanical advantage, allowing one-handed operation while maintaining secure clamping force, thus eliminating the need for tools while preserving adjustability.
Solution Approach 2:
The clamp's closing mechanism is designed to be self-operating through manual leverage, eliminating the need for external tools like wrenches. The mechanical advantage provided by the lever arm allows the user's hand force to directly control the clamping action without requiring additional devices.
3Device complexity
If prior art cable clamps have fixed clamping surfaces, then the clamps are simple in design, but they cannot accommodate different cable sizes without removal or adjustment
Solution Approach 1:
The rubber gaskets serve multiple functions: they provide a compliant surface that adapts to different cable diameters, protect the cable from damage, and maintain consistent clamping pressure. This multi-functionality allows a single clamp design to handle various cable sizes without modification.
Solution Approach 2:
The rubber material's elasticity allows the gaskets to deform and adapt their shape and size to match different cable diameters. This parameter change in the gasket's physical state enables the clamp to accommodate a range of cable sizes while maintaining a simple overall design.
4Device complexity
If prior art cable clamps require top portion removal to insert cables, then the clamps have a simple closure mechanism, but they create more work and reduce efficiency
Solution Approach 1:
The hinge-connected top plate creates a dynamic opening mechanism that allows the clamp to be easily opened by lifting the plate, eliminating the need for removal. This dynamic design maintains closure simplicity while dramatically improving operational efficiency through one-handed operation.

AI summary
A cable clamp for use with telecommunication cables. The cable clamp is a two piece design comprising a top plate and a bottom plate. The cable clamp having a first closing mechanism arranged on a first end thereof and a second closing mechanism arranged on a second end thereof. The top plate includes a gasket arranged on an inner surface thereof. The bottom plate includes a first and second gasket arranged on a top surface thereof. The cables are in contact with the gaskets from both plates, thus securing them in a predetermined position for prepping and splicing.
