Removable Reference Point Marker With Residue-Free Adhesive Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking devices for defining reference points on objects are difficult to remove without causing damage, especially when subsequent coatings or modifications are required.
Innovation Solution
A marking device with a base fixed using double-sided adhesive tape, featuring a chamfered edge with an undercut, allows for easy removal by a removal tool, ensuring no residue is left behind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the marking device is attached to the object's surface with hot glue, then the marking device is firmly fixed to the surface, but the marking device cannot be removed without causing damage
Solution Approach 1:
The patent changes the attachment method from permanent (hot glue) to removable (double-sided adhesive tape). This parameter change in the bonding mechanism allows the marking device to be both firmly fixed during measurement and easily removed afterward, resolving the contradiction between attachment strength and removability.
2Ease of repair
If the marking device is removed from the object surface, then the marking device can be reused, but residue may be left on the surface or the device may be damaged
Solution Approach 1:
The patent employs a disposable double-sided adhesive tape that can be cleanly removed from both the marking device base and the object surface. This allows the marking device to be reused without damage or residue, while the tape itself serves as a consumable element that ensures clean separation.
3Ease of operation
If a tab is added to the base for detaching the marking device, then the marking device can be easily removed, but the tab poses a tripping hazard when attached to the floor
Solution Approach 1:
The patent extracts the removal function from a protruding tab structure and integrates it into the base itself through an undercut feature. This allows the removal tool to engage with the base edge without requiring any protruding elements, eliminating the tripping hazard while maintaining easy removability.
4Stability of the object's composition
If the base is firmly attached to the object, then the marking device remains stable during measurement, but the base cannot be removed for subsequent coatings or modifications
Solution Approach 1:
The patent transforms the attachment system from a static permanent bond (hot glue) to a dynamic removable bond (double-sided adhesive tape). This allows the marking device to be stably attached during measurement operations and then easily removed when subsequent coatings or modifications are needed, providing both stability and flexibility.

AI summary
The invention relates to a marking device for defining one or more reference points (R) on an object (1) during object measurement. For this purpose, the marking device has a base (2) and a marking carrier (3), which together serve to define the reference point (R). The base (2) is designed to be connectable to the object (1). According to the invention, the base (2) can be attached to the object (1) without leaving any residue by means of a double-sided adhesive tape (5), in particular one with a thickness of less than 600 µm.
