Solution Overview

Problem

Existing plug-in elements for mechanically fixing pipes and providing electrical contacting often compromise either mechanical fixation or electrical reliability, leading to complex assemblies and insufficient performance in combining both functions.

Innovation Solution

A plug-in element featuring two interconnected U-shaped brackets, where one bracket ensures secure mechanical fixation and the other optimizes electrical contacting, with additional features like parallel arrangement and recesses for enhanced handling and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single U-shaped bracket is used to combine both mechanical fixation and electrical contacting functions, then the device complexity is reduced, but the reliability of both functions deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The single U-shaped bracket is segmented into two separate U-shaped brackets: one dedicated to mechanical fixation and another dedicated to electrical contacting. This segmentation allows each bracket to optimize its specific function, thereby improving overall reliability while maintaining relatively low device complexity through integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies multi-functionality by integrating both fixation and electrical contacting functions into a single plug-in element that contains two specialized brackets. This approach reduces device complexity by combining multiple functions in one component while maintaining high reliability through functional specialization of each bracket.

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

2Reliability

If separate clamps are used for mechanical fixation and electrical coupling, then the reliability of each function is improved, but the device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Two separate functional brackets (mechanical fixation and electrical coupling) are merged into a single integrated plug-in element. This merging maintains the reliability benefits of separate specialized components while reducing device complexity by combining them into one unified structure.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If additional assembly steps are introduced for electrical connection, then the reliability of electrical contacting is improved, but the ease of operation deteriorates

Engineering Contradiction:
ImprovereliabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The electrical connection components are pre-integrated into the plug-in element during manufacturing, so that during installation, the electrical contacting is established automatically as part of the single insertion action. This preliminary integration maintains reliable electrical contacting while eliminating additional assembly steps, thereby improving ease of operation.

Inventive Principle:
Principle #10Preliminary action
