Solution Overview

Problem

Existing electrical installation devices face challenges in securely and easily attaching and detaching inscription labels without risking damage to the clip elements or the label itself, as the keyhole-like fastening holes are often compromised, and there's a risk of improper reattachment.

Innovation Solution

The solution involves attaching the inscription label to the outer edge areas of the carrier using clamping springs that engage with holding pockets and retaining pins, allowing for secure, precise positioning and easy removal without adhesives, preserving the functionality of keyhole-like fastening holes for device fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If clip elements are used to fix the inscription plate in the keyhole-like fastening holes, then the inscription plate can be attached, but the keyhole-like fastening hole can no longer be used to fix the electrical installation device at its installation location

Engineering Contradiction:
Improveattachment of inscription plateVSAvoidusage of keyhole-like fastening hole
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The fastening system is divided into two separate functions: the keyhole-like fastening holes remain dedicated to mounting the electrical installation device at its installation location, while separate attachment means (adhesive or夹持 elements) are introduced specifically for fixing the inscription plate. This segmentation prevents the keyhole holes from being occupied by inscription plate fasteners, preserving their original function while enabling inscription plate attachment.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If clip elements are used to attach the inscription plate, then the inscription plate can be fixed, but there is a risk that the clip elements will be damaged during loading and removing operations

Engineering Contradiction:
Improveattachment of inscription plateVSAvoidintegrity of clip elements
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention employs adhesive strips or disposable夹持 elements that are inexpensive and can be replaced if damaged during attachment or removal operations. These consumable attachment means protect the more valuable and permanent clip elements and keyhole-like fastening holes from damage, as the adhesive or disposable components bear the mechanical stress of installation and removal.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design ensures a universally retrofittable and detachable inscription label that can be securely attached and removed without damaging the components, maintaining the integrity of the installation device's fastening system and providing clear user information through transparent or opaque labeling options.

Implementation Method 1

two clamping springs (6), which are to be handled separately, being used for fixing. The two clamping springs (6) each engage with a first spring leg (6a) in a holding pocket (7) present in the inscription plate (4) and come to rest with a second spring leg (6b) behind the main surface of the carrier (1)

AI summary

The apparatus has a carrier (1) provided with a viewing window, and a universal expandable decal (4) secured to an outer edge region (5) of the carrier, where the decal is defined by using a clamping spring (6). The clamping spring includes a spring part (6a) engaged with a holding pocket (7) in the decal. A halt recess (8) is positioned at the outer edge region and engaged with a halt bar at the decal. A major surface of the carrier is positioned behind another spring part (6b) of the clamping spring by moving a covering frame.
