Solution Overview

Problem

Existing cable support systems require complex and error-prone assembly processes, involving multiple steps and the manual bending of locking tabs, which increases assembly time and risk of errors.

Innovation Solution

A cable support system with undercut receptacles on the support devices and clamping sections on the cable carrier, where the undercuts project beyond the clamping sections in the assembly direction, allowing for a form-fitting attachment without additional elements or manual bending, simplifying the assembly process and ensuring secure fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional fastening elements or locking tabs are used to attach the cable carrier to the support device, then the connection security is improved, but the assembly complexity and time increase

Engineering Contradiction:
Improveconnection securityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the fastening function from separate additional elements and integrates it directly into the support device structure through undercut receptacles. The undercut geometry itself provides the locking mechanism, eliminating the need for separate fastening elements or locking tabs that would otherwise be required to achieve secure connection.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The undercut receptacles are designed to automatically lock the cable carrier in place through their geometric shape. When the cable carrier is inserted, the undercut features engage with corresponding features on the carrier, creating a self-locking mechanism that requires no manual intervention for fastening, thereby simplifying assembly while maintaining connection security.

Inventive Principle:
Principle #25Self-service

2Stability of the object's composition

If locking tabs are bent during assembly to fix the cable carrier, then the connection stability is improved, but the assembly time and error risk increase

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

Instead of requiring active manipulation (bending) of locking tabs during assembly, the patent inverts the approach by designing receptacles that passively engage and lock components through their undercut geometry. The locking action occurs automatically upon insertion, reversing the traditional sequence where components must be actively secured after positioning.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the manual mechanical action of bending locking tabs with a geometric interlocking system. The undercut receptacles create a mechanical lock through their shape alone, substituting the need for manual tab bending with an automatic geometric engagement mechanism that achieves the same stability without the time-consuming manual operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Force

If multiple support structures are used to support the cable tray, then the load distribution is improved, but the assembly effort increases

Engineering Contradiction:
Improveload distributionVSAvoidassembly effort
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The undercut receptacle design serves multiple functions simultaneously: it provides structural support, creates a locking mechanism, and enables simple assembly all through a single geometric feature. This multi-functionality allows multiple support structures to be used for proper load distribution while keeping each individual support device simple and quick to assemble.

Inventive Principle:
Principle #6Universality (Multi-functionality)
