Identification Strip With Soft Grip Zones for Groove Slip Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification strips for electrical installations tend to slip within mounting grooves due to environmental influences and vibrations, leading to potential dislodgment or complete removal.
Innovation Solution
The identification strip features a marking area and clamping area made of different plastics, where the softer second plastic forms adhesive areas to increase static friction, ensuring reliable attachment by engaging in a mounting groove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a marking strip is clamped into a mounting groove for attachment, then the marking strip can be fixed to the electrical installation, but the marking strip tends to slip within the groove due to environmental influences and vibrations
Solution Approach 1:
The marking strip incorporates adhesive areas with a different material property (softer second plastic) at specific locations where contact with the mounting groove occurs, while the marking area maintains its original harder first plastic material. This local differentiation of material properties increases static friction at the contact points without affecting the marking functionality.
Solution Approach 2:
The invention changes the material parameter (hardness/Shore value) of specific areas of the marking strip. The adhesive areas are made softer (lower Shore hardness) than the main body, which increases the coefficient of static friction and thereby improves grip within the mounting groove, preventing slippage under vibration and environmental influences.
2Strength
If the marking strip is made of a single hard plastic material, then the marking area remains durable and printable, but the strip lacks sufficient friction to prevent slipping in the mounting groove
Solution Approach 1:
The marking strip is constructed as a composite object with at least two different plastic materials: a harder first plastic for the marking area that provides durability and printability, and a softer second plastic for the adhesive areas that provides increased static friction and slip resistance. This composite structure allows each area to optimize its function.
Solution Approach 2:
Different material properties are assigned to different locations of the marking strip. The adhesive areas use softer material to maximize friction with the mounting groove surfaces, while the marking area uses harder material to maintain structural integrity and resistance to environmental influences.
