Solution Overview

Problem

Existing front panel sections for busbar systems fail to securely anchor electrical installation devices, leading to unintended release due to vibrations or movements.

Innovation Solution

A front panel section with projections on its mounting level that block movement in a specific direction, requiring targeted action to release, combined with installation devices featuring structures that complement these projections and a spring-held bolt for secure fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If front panel sections have through-slots for installing devices, then installation ease is improved, but device security against accidental release deteriorates

Engineering Contradiction:
Improveinstallation easeVSAvoiddevice security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The front panel is segmented into multiple functional elements: through-slots for insertion, projections for blocking movement, and complementary structures on installation devices. This segmentation allows each element to perform its specific function independently, resolving the contradiction between ease of installation and device security.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Projections are pre-positioned on the mounting plane to block movement in the second direction before any accidental contact or vibration can occur. This preliminary blocking action prevents the harmful effect of accidental release while maintaining easy installation through the through-slots.

Inventive Principle:
Principle #9Preliminary anti-action

2Productivity

If devices are easily inserted through through-slots, then installation time is reduced, but resistance to vibrations and movements deteriorates

Engineering Contradiction:
Improveinstallation timeVSAvoidresistance to vibrations
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The projections are pre-positioned on the mounting plane to provide immediate blocking action as soon as the installation device is inserted through the through-slot. This preliminary blocking prevents vibrations and movements from causing release, while the simple through-slot design maintains fast installation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If projections block movement in second direction, then device anchorage reliability is improved, but ease of release deteriorates

Engineering Contradiction:
Improveanchorage reliabilityVSAvoidease of release
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The projection geometry creates asymmetric blocking: it strongly resists movement in the second direction (improving anchorage) but allows controlled release when complementary structures on the installation device engage with the projections. This asymmetry resolves the contradiction between secure anchorage and ease of release.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The projections act as intermediary elements between the mounting plane and the installation device. They provide the blocking function for reliability while their interaction with complementary structures enables controlled release, mediating between the conflicting requirements of secure anchorage and ease of release.

Inventive Principle:
Principle #24Intermediary (Mediator)
