Solution Overview

Problem

Current cable clamping devices for water heaters are inadequate as they fail to securely hold cables under traction, torsion, or compression and are impractical for installation, potentially leading to safety concerns due to improper use.

Innovation Solution

A cable clamping device with a mobile part and support end that moves between clamping and release positions, featuring an inclined plane and screw mechanism for secure cable retention, along with a mounting system that includes latching means for easy installation and compatibility with various cable diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple collar is used to clamp the cable, then the device complexity is reduced, but the cable retention reliability under traction, torsion, or compression deteriorates

Engineering Contradiction:
Improveclamping device structureVSAvoidcable retention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The collar is designed with a movable clamping element that can dynamically adjust between a release position and a clamping position. The mobile part includes a support end that moves along the cable axis, enabling the device to adapt to different cable positions and maintain reliable retention under various forces (traction, torsion, compression) while keeping the overall structure relatively simple.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a secure clamping mechanism is implemented, then the cable retention reliability is improved, but the ease of operation deteriorates due to impractical installation

Engineering Contradiction:
Improvecable retentionVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The collar is pre-equipped with a control member that enables the mobile part to be easily moved between release and clamping positions. The control member translates rotational motion into linear displacement of the support end, allowing the installer to quickly and practically secure the cable without complex manual adjustment, thus maintaining ease of operation while ensuring reliable retention.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the mobile part is designed to move between clamping and release positions, then the adaptability is improved, but the device complexity increases due to additional components

Engineering Contradiction:
Improvecable positioning flexibilityVSAvoidclamping device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control member is integrated directly into the collar structure, merging the control function with the clamping body. The control member carries an inclined plane that cooperates with the mobile part, combining multiple functions (control, motion transmission, and clamping) into a single integrated component. This reduces the number of separate parts while maintaining the adaptability to position cables of different diameters and the ability to switch between clamping and release states.

Inventive Principle:
Principle #5Merging (Combining)
