Information Holder with Segmented Adhesive for Damage-Free Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information carrier holding devices, such as info frames, often damage carrier surfaces like wallpaper when detached due to the adhesive film used for attachment, making it difficult to remove them without causing damage.
Innovation Solution
An information carrier holding device with a flat, foil-like base element featuring a peripheral edge with magnetically active elements and defined partial adhesive areas, allowing for secure attachment and easy detachment without damaging the carrier surface, using partial adhesive elements that can be reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complete adhesive film covers the entire rear side of the base element for secure attachment, then the attachment strength is improved, but the carrier surface is damaged upon detachment
Solution Approach 1:
The adhesive film is segmented into multiple separate adhesive elements distributed across the rear side of the base element. Each adhesive element is isolated and can be individually removed from the carrier surface upon detachment, preventing the entire adhesive film from tearing the carrier surface. This segmentation maintains secure attachment during use while enabling damage-free removal.
Solution Approach 2:
The adhesive elements are designed to be extractable from the base element and carrier surface. Upon detachment, the adhesive elements can be completely removed from the carrier surface, taking the adhesive force with them and leaving no residue that could damage the carrier surface. This extraction capability resolves the contradiction between secure attachment and damage-free removal.
2Stability of the object's composition
If adhesive elements are distributed across the entire rear side of the base element, then the attachment stability is improved, but the complexity of the device structure increases
Solution Approach 1:
Instead of distributing adhesive elements uniformly across the entire rear side, the invention uses a partial arrangement where adhesive elements are positioned only at critical locations such as corners or edges of the base element. This partial action provides sufficient attachment stability for the intended application while minimizing the number of adhesive elements, thereby reducing device complexity.
Solution Approach 2:
The adhesive elements are strategically positioned at specific locations on the base element where they provide maximum attachment stability with minimum quantity. This local quality approach concentrates adhesive function at critical points rather than distributing it uniformly, achieving stable attachment without increasing overall device complexity.
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
The solution enables secure attachment and easy, damage-free detachment of information carriers from various surfaces, including sensitive substrates, with reduced risk of damage and allowing for multiple uses of the holding device.
Implementation Method 1
The magnetically active element is arranged in this (rear) edge area of the cover element in such a way that it interacts with the magnetically active element of the base element. By means of a magnetic attraction between the magnetically active elements, the base element and the cover element can be held in an intended arrangement relative to one another
Implementation Method 2
a number of adhesive elements, each with an adhesive surface, can be arranged in a respective defined adhesive area on a rear side of the base element. The adhesive elements create adhesive connection between the base element and the carrier surface
