Solution Overview

Problem

Existing adapters for electrical installation devices on busbar systems are limited to contacting only one conductor at a time, requiring multiple adapters for different conductors, which is inefficient and inconvenient.

Innovation Solution

A modular adapter system with a displaceable second contact element and latching mechanism, allowing the adapter to be adjusted to contact multiple conductors by sliding the second contact element along guide receptacles and engaging latching means at predetermined positions, enabling the adapter to be used with various busbar conductors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single contact element is used in the adapter, then the adapter structure is simple, but the adapter can only contact one conductor at a time requiring multiple adapters for different conductors

Engineering Contradiction:
Improveability to contact multiple conductorsVSAvoidadapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The second contact element is made displaceable along the guide receptacle instead of being fixed, allowing it to be positioned at different latching positions to contact different conductors. This dynamic positioning capability enables a single adapter to contact multiple conductors while maintaining a relatively simple structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adapter is designed with a displaceable second contact element that can be positioned at multiple latching positions, allowing the same adapter to contact different conductors (L1, L2, L3, N, or PE). This multi-functionality eliminates the need for multiple specialized adapters.

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

2Adaptability or versatility

If multiple fixed contact elements are provided for different conductors, then all conductors can be contacted, but the adapter requires multiple different adapter types

Engineering Contradiction:
Improvecontacting different conductorsVSAvoidadapter selection and installation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of providing multiple fixed contact elements in different adapter types, the invention uses a single displaceable second contact element that can be moved to different latching positions. This dynamic design allows one universal adapter to replace multiple specialized adapters, making installation and selection easier.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the second contact element is fixed in position, then the adapter structure is simple, but the adapter cannot be adjusted for different conductors

Engineering Contradiction:
Improveadjustability for different conductorsVSAvoidguide receptacle and latching mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The second contact element is designed to be displaceable along the guide receptacle with multiple latching positions. This dynamic positioning mechanism, while adding some structural complexity through the guide receptacle and latching means, enables the adapter to adapt to different conductors.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide receptacle is divided into multiple discrete latching positions along its length, allowing the second contact element to be positioned at specific locations for contacting different conductors. This segmentation provides precise positioning while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation
