Solution Overview

Problem

Existing electrical systems face challenges in securely connecting conductors to support structures, particularly in high-to-low voltage transformers and power distribution modules, due to mechanical forces from electromagnetic surges and short circuits, which can lead to operational instability and reliability issues.

Innovation Solution

A bracing system comprising modular conductor supports with clip bodies and catches that snap together to securely hold conductors in place, featuring cantilevered and deflector legs with acute engagement angles, allowing for easy installation and secure alignment of conductors relative to electrical devices and building structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional conductor securing methods are used, then installation is simple, but the conductor connection is not secure against mechanical forces from electromagnetic surges and short circuits

Engineering Contradiction:
Improveconductor connection securityVSAvoidbracing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The conductor support is divided into multiple clip bodies (first clip body and second clip body) that can be separately installed and then engaged together. Each clip body has independent catches that interlock to secure the conductor, allowing modular installation and replacement while maintaining secure mechanical fastening against electromagnetic forces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first and second clip bodies are combined through their interlocking catches to form a unified securing mechanism. The catches of one clip body engage with the catches of the other, creating a merged structure that firmly holds the conductor in place while distributing mechanical stress across multiple engagement points.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If modular clip bodies with interlocking catches are used, then conductor alignment is improved, but installation complexity increases

Engineering Contradiction:
Improveconductor alignmentVSAvoidinstallation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The clip bodies feature self-aligning catches that automatically engage with each other when the clip bodies are brought together. The geometric configuration of the catches ensures proper alignment during installation without requiring additional alignment tools or complex procedures, allowing the structure to self-correct minor positioning errors.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The catches are designed with specific geometric parameters including acute engagement angles and complementary shapes that enable easy engagement. By optimizing the angle and dimensions of the catch surfaces, the system achieves precise conductor alignment while maintaining simple snap-together installation mechanics.

Inventive Principle:
Principle #35Parameter changes

3Strength

If multiple clip bodies are engaged to secure conductors, then mechanical strength is improved, but device complexity increases

Engineering Contradiction:
Improvemechanical support strengthVSAvoidclip body assembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The catches of the first and second clip bodies are designed with asymmetric geometries that complement each other. The catches have different shapes and engagement orientations, allowing them to interlock in a specific configuration that maximizes mechanical strength while preventing unintended disengagement during installation or operation.

Inventive Principle:
Principle #4Asymmetry
