Repositionable Tape Kit for Intercom Name Tag Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern outdoor audio and video intercommunication systems with flush-mounted name tags face difficulties in removing the name tags due to their design, which often results in a low clearance cavity, making it hard to replace or update the name tags.
Innovation Solution
A name tag kit utilizing a repositionable double-sided tape with different peel-off forces for the name tag and the light guide, along with a removal tool, allows for easy attachment and detachment of the name tags, ensuring a clean surface for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a name tag is provided flush to the front plate with low clearance cavity, then the design is modern and clean, but the name tag becomes very difficult to remove
Solution Approach 1:
The adhesive system is segmented into two distinct glue layers with different properties: a first glue layer with high initial adhesion for secure mounting, and a second glue layer with controlled adhesion for easy removal. This segmentation allows the name tag to simultaneously achieve flush-mounted stability and ease of replacement.
Solution Approach 2:
The adhesive system transitions from a static, permanently bonded state to a dynamic, controllable adhesion state. The two-stage adhesive mechanism allows the bonding strength to change based on the removal phase: strong initially for secure mounting, then controllable for easy removal when the second liner is peeled.
2Strength
If a double-sided adhesive tape is used to attach the name tag, then the name tag can be securely fixed, but the light guide surface becomes contaminated with glue or carrier upon removal
Solution Approach 1:
The adhesive system is extracted from a single-layer configuration to a multi-layer configuration with distinct functional layers. The first glue layer remains on the carrier for secure bonding, while the second glue layer is designed to be completely removed from the light guide surface, extracting the harmful residue problem by separating the bonding function from the surface contact function.
Solution Approach 2:
The carrier acts as an intermediary element between the adhesive and the light guide surface. It holds the first glue layer for secure bonding while allowing the second glue layer to be cleanly removed from the light guide, mediating between the need for strong adhesion and clean surface removal.
3Device complexity
If the same adhesive is used on both sides of the tape, then the application is simple, but the removal process is difficult and leaves residue
Solution Approach 1:
Different adhesive properties are applied to different sides of the tape carrier: the first glue layer has high initial adhesion and controlled release properties for secure mounting, while the second glue layer has lower adhesion for easy removal. This local differentiation of adhesive quality enables both secure fixing and easy removal without requiring complex application procedures.

AI summary
The present invention provides a name tag kit for providing and removing a name tag (3) to and from a light guide (9) of an audio and/or video intercommunication system (1). The name tag kit comprises a name tag (3) and a repositionable tape (14) for fixing the name tag (3) to the light guide (9). The repositionable tape (14) is a double sided tape comprising a carrier (21), and a first liner (22) attached to a front side of the carrier (21) by means of a first glue layer (23) and a second liner (24) attached to a back side of the carrier (21) by means of a second glue layer (25). According to embodiments of the invention, the second glue layer (25) is different from the first glue layer (23) in terms of peel-off force.
