Elastic Label Holder for Electrical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inscription carriers for electrical installation devices face issues with readability due to varying installation positions and moisture exposure, leading to label misalignment and degradation.
Innovation Solution
The inscription carrier features a resilient connecting section allowing elastic movement to maintain optimal label positioning relative to the viewing window and incorporates a predominantly open sign holder to prevent capillary effects and facilitate moisture drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inscription carrier is designed with a fixed position, then the label position is stable, but it cannot adapt to varying installation positions of the device insert
Solution Approach 1:
The inscription carrier is designed with a resilient connecting section that allows dynamic movement between a relaxed initial position and a compressed position. This enables the receiving section to adapt to varying distances between the device insert and cover frame while maintaining optimal label positioning relative to the viewing window
2Ease of operation
If the receiving space for the inscription plate is narrow and slit-like, then the label is securely held, but moisture penetration occurs through capillary action
Solution Approach 1:
The receiving section is designed with a predominantly open structure that allows moisture to evaporate freely, preventing capillary action while still securely holding the inscription plate through the resilient connecting section and lateral holding areas
3Measurement precision
If the inscription carrier is positioned for optimal readability, then the label is clearly visible, but it acts as a spacer preventing correct mounting of the cover frame
Solution Approach 1:
The resilient connecting section allows the receiving section to be compressed during cover frame assembly, eliminating spacing issues that would prevent proper mounting. After assembly, the section returns to its relaxed position, ensuring optimal label readability through the viewing window
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
Ensures consistent readability over time by adapting to different installation scenarios and preventing label degradation from moisture exposure.
Implementation Method 1
the receiving section (14) is connected to the base section (12) via a resilient connecting section (32) in such a way that the receiving section (14) can be moved from a relaxed initial position against a spring force in the direction of the connecting section (32)
Implementation Method 2
Since the inscription carrier has a relatively narrow, slit-like receiving space for the inscription plate, the penetrating moisture can dry off only with great difficulty. In addition, capillary action even leads to increased penetration of moisture over the entire labeling surface

AI summary
The holder (10) has a base section (12) for attachment to a device insert, and a retaining section (14) for holding a laminar label plate (16). The retaining section is connected with the base section by a spring-elastic connecting section (32) such that the retaining section is movable from a relaxed starting position toward the base section against a spring force. The base section changes into the retaining section over the connecting section that comprises elastically deformable spring arms (34), where the holder is designed as an integrally shaped part made of plastic.
