Solution Overview
Problem
Existing micro suction materials fail to securely attach objects to rough or uncoated surfaces, such as paper or card, and are prone to reduced adhesion due to fiber deposition and chemical coatings, limiting their reusability and environmental sustainability.
Innovation Solution
A method involving a graphic display sheet with a micro vacuum receptor layer, comprising a high gloss, silicone-free polyester-based varnish, which forms an air-tight seal with a micro suction coating on a display substrate, allowing secure temporary attachment to smooth surfaces and preventing fiber deposition and chemical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro suction materials are used to attach objects to rough or uncoated surfaces, then attachment is achieved on smooth surfaces, but adhesion is reduced due to fiber deposition and chemical coatings
Solution Approach 1:
A release paper layer is introduced as an intermediary between the micro suction coating and the graphic display sheet. This release paper prevents direct contact between the micro suction coating and fibers/chemical coatings from the graphic display sheet, thereby eliminating the harmful effects of fiber deposition and chemical interference while maintaining the attachment function.
Solution Approach 2:
The invention uses a release paper that mimics the non-stick properties of the micro suction coating's release mechanism. The release paper is designed to be non-adhesive to both the micro suction coating and the graphic display sheet, effectively copying the release function and preventing contamination.
2Adaptability or versatility
If graphic display sheets are frequently changed on micro suction materials, then versatility is improved, but adhesion strength decreases over multiple changes
Solution Approach 1:
The release paper acts as a mediator that protects the micro suction coating from direct contact and potential damage during repeated attachment and detachment cycles. This intermediary layer maintains the integrity of the micro suction coating, ensuring consistent adhesion strength over multiple changes while enabling frequent replacements.
Solution Approach 2:
The invention allows the graphic display sheet and release paper combination to be discarded and replaced, while the micro suction coating on the display substrate is recovered and reused. This approach maintains the adhesion strength of the reusable micro suction material while enabling frequent changes of the display content.
3Ease of manufacture
If standard paper materials are used for graphic display sheets, then ease of manufacture is improved, but moisture ingress breaks the vacuum seal
Solution Approach 1:
The release paper serves as a moisture barrier intermediary between the standard paper graphic display sheet and the micro suction coating. This intermediary layer prevents moisture from the paper from reaching the micro suction coating, thereby maintaining the vacuum seal integrity while allowing the use of easily manufactured standard paper materials.
Solution Approach 2:
The release paper functions as a thin film barrier that is flexible enough to conform to the surfaces it contacts while providing effective moisture protection. This thin film maintains the vacuum seal by blocking moisture ingress from the paper substrate.

AI summary
A graphic display sheet (3) or other object has a micro vacuum receptor layer (9) on one side, for attachment to a micro suction layer (7). The micro vacuum receptor layer (9) is provided by a high gloss, silicone free, polyester-based varnish. In the case of the graphic display sheet (3), a printed display side (11) is opposite to the micro vacuum receptor layer (9).
