Solution Overview

Problem

Existing cable clamps are limited in their ability to securely support cables with a wide range of diameters without damaging the cable sheath, particularly in adverse weather conditions, and often require additional components like gaskets, leading to complex installations and increased costs.

Innovation Solution

A saddle design comprising two half-saddles, one made of plastic and the other of elastomeric material, with radial protrusions forming a continuous ring that uniformly distributes pressure along the cable circumference, ensuring stable fixation without mechanical interference or sheath damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blocking teeth are used to secure cables in rigid plastic saddles, then cable fixation stability is improved, but the cable sheath may be perforated or damaged

Engineering Contradiction:
Improvecable fixation stabilityVSAvoidsheath damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the material parameter of the saddle from rigid plastic to elastomeric material, which allows the saddle to deform elastically and adapt to different cable diameters without perforating the sheath, while still providing secure fixation through friction and elastic recovery

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses composite construction with an elastomeric outer layer for cable contact and a rigid inner structure for mechanical strength, combining the advantages of both material types to prevent sheath damage while maintaining fixation stability

Inventive Principle:
Principle #40Composite materials

2Reliability

If rigid plastic saddles with teeth are used, then cable blocking capability is improved, but adaptability to different cable diameters is reduced

Engineering Contradiction:
Improvecable blocking capabilityVSAvoidadaptability to different cable diameters
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention changes the material parameter from rigid to elastomeric, enabling the saddle to elastically deform and adapt to various cable diameters while maintaining effective blocking capability through friction and geometric interlocking

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention introduces dynamic adaptability by using elastomeric material that can deform under load to accommodate different cable sizes, then recover its shape to maintain securing force, making the saddle versatile across multiple cable diameters

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If multiple components including gaskets are used for cable fixation, then protection against sheath damage is improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improveprotection against sheath damageVSAvoidinstallation complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention merges the protective function previously requiring separate gaskets into the saddle itself by using elastomeric material that inherently protects the cable sheath while providing fixation, eliminating the need for additional components and simplifying installation

Inventive Principle:
Principle #5Merging (Combining)

4Strength

If rigid plastic material is used for saddles, then structural strength is improved, but ability to uniformly distribute pressure on cable circumference is reduced

Engineering Contradiction:
Improvesaddle structural strengthVSAvoidpressure distribution uniformity
Core Design Contradiction:
StrengthVSStress or pressure

Solution Approach 1:

The invention uses composite construction combining elastomeric outer layer for uniform pressure distribution and elastic deformation with an inner rigid structure for overall structural strength, achieving both pressure uniformity and mechanical strength

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention changes the material parameter to elastomeric, which allows uniform pressure distribution through elastic deformation and recovery, while the composite structure maintains the necessary structural strength for load-bearing applications

Inventive Principle:
Principle #35Parameter changes
