Solution Overview

Problem

Existing U-clamps for fastening long-form goods like cables to profile rails require multiple parts and fail to securely fix two parallel cables, leading to increased inventory needs and instability under tensile or compressive forces.

Innovation Solution

A counter trough with a profile on one side that can connect with another identical trough to form a double trough, using longitudinal webs or dovetail-like projections for secure positioning and locking, reducing the number of parts needed and ensuring stable fixation of two cables within a single clamp.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a double tray with different shape is used to secure two parallel cables, then the clamp can hold two cables, but the fitter has to stock a larger number of parts and the double trays have no positional fixation between the cables

Engineering Contradiction:
Improveability to hold two parallel cablesVSAvoidnumber of different parts to stock
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The double tray is segmented into two identical single trays that can be connected together. Each single tray has the same standardized shape and can be used independently or combined. The connection is achieved through profile elements (longitudinal ribs) that engage with corresponding recesses, allowing two identical trays to form a stable double tray structure without requiring separately shaped double trays.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a double tray with different shape is used to secure two parallel cables, then the clamp can hold two cables, but these double trays have no positional fixation between the cables in tensile or shearing direction

Engineering Contradiction:
Improveability to hold two parallel cablesVSAvoidpositional fixation between cables
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The profile elements (longitudinal ribs and recesses) are pre-formed on the single trays during manufacturing. When two trays are connected, these pre-formed features automatically provide positional fixation and prevent displacement in tensile and shearing directions, eliminating the need for additional fixation mechanisms.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple different shaped trays are stocked for different cable configurations, then various cable arrangements can be secured, but inventory requirements and part complexity increase

Engineering Contradiction:
Improveability to secure different cable configurationsVSAvoidnumber of parts to keep in stock
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The single tray design serves multiple functions: it can be used alone for single cable support, connected to another identical tray for dual cable support, and the connection can be configured in different orientations. The universal profile elements (longitudinal ribs and recesses) enable this multi-functionality, allowing one standardized part to replace multiple specialized parts.

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

AI summary

In order to create a clamp (1) for fastening long components, such as cables (2), to a profile rail, which reduces the number of parts to be kept in stock by the installer on site, and which, on the other hand, after positioning between two long components such as cables arranged parallel to each other, provides a travel limitation both in the insertion direction and in the pulling direction of the long component, and which is cost-effective and easy to manufacture and has a long service life, it is proposed that the counter tray (8) has a profile on its side facing away from the long component, in particular cables (2), by means of which the counter tray (8) can be connected or joined to the profile of another, identical counter tray (8) to form a double tray (18).
