Solution Overview

Problem

Existing electrical device assemblies are complex, inconvenient, and costly, with limited flexibility in mounting additional functional components like label holders and covering plates.

Innovation Solution

A support plate with snap-fastening zones on both sides, allowing secure attachment of a covering plate and additional functional members like label holders, using guide and latching members that snap into these zones, enabling flexible and economical mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional support plates with limited snap-in areas are used, then mounting of covering plates is possible, but mounting of additional functional members is not possible or requires complex modifications

Engineering Contradiction:
Improvemounting flexibilityVSAvoidsupport plate structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support plate is designed with multiple identical snap-in zones distributed on its surface, allowing the same plate structure to accommodate different combinations of covering plates and additional functional members without modification. Each snap-in zone can receive various types of components, making the support plate universally adaptable to different mounting configurations.

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

2Adaptability or versatility

If multiple identical snap-in zones are provided on the support plate, then both covering plates and additional functional members can be mounted, but the manufacturing cost increases

Engineering Contradiction:
Improvecomponent mounting optionsVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The support plate is segmented into multiple identical snap-in zones, each capable of independently mounting a component. This segmentation allows standardized mass production of the support plate with repetitive features, reducing per-unit manufacturing costs despite the increased versatility. The modular snap-in zone design enables efficient manufacturing processes.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the label holder ends extend behind the mounting frame projections, then secure mounting is achieved, but mounting from the rear face is hindered

Engineering Contradiction:
Improvemounting securityVSAvoidmounting accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The snap-in zones are positioned and designed to receive components from the front face of the support plate, changing the mounting dimension from rear-face insertion to front-face attachment. This dimensional change allows the label holder and other components to be securely mounted without interfering with rear face accessibility, as the securing action occurs at the front while the rear remains clear for mounting to the wall or support structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
