Reusable Note Support With Micro Suction Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-adhesive note supports, such as 'post-its', have limitations including a small adherent area, short useful life, and lack of resistance to water and moisture, making them single-use and not suitable for repeated use or environmental sustainability.
Innovation Solution
A reusable note support featuring a flat laminar body with micro suction cups distributed in a staggered pattern on one surface and a writable surface on the other, made from opaque polymeric calendered vinyl, allowing adherence to various surfaces and easy removal, with optional vinyl sheets and washable design to maintain adhesive performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional self-adhesive paper cards (post-its) are used, then notes can be left visible on surfaces, but the adhesive stops performing properly after repeated removal and reattachment, making them single-use
Solution Approach 1:
The patent replaces the chemical adhesive system with a mechanical suction system. Instead of using adhesive that degrades over time, the note support uses micro suction cups that create vacuum adhesion through pressure differential. This mechanical system can be repeatedly activated by pressing and deactivated by lifting, allowing multiple removal and reattachment cycles without performance degradation.
Solution Approach 2:
The patent changes the adhesion mechanism from chemical bonding to physical vacuum pressure. By creating numerous small vacuum chambers through the micro suction cup structure, the system maintains consistent adhesion force across multiple uses. The parameter of adhesion strength is maintained by replenishing the vacuum pressure rather than degrading chemical bonds.
2Productivity
If conventional self-adhesive paper cards are used, then notes can be attached to surfaces, but they have a very short useful life and must be discarded after single use
Solution Approach 1:
The patent enables recovery and reuse of the note support itself. Instead of discarding the entire card after one use, the micro suction cup structure allows the support to be removed, cleaned, and reattached multiple times. Only the written notes are discarded, while the support structure is recovered and reused indefinitely, dramatically reducing material waste.
Solution Approach 2:
The patent inverts the disposable concept by making the support structure permanent and reusable while the notes remain temporary. The micro suction cup mechanism creates a durable, washable support that replaces the disposable nature of traditional post-its, allowing the same support to serve hundreds or thousands of note-taking cycles.
3Object-affected harmful factors
If conventional self-adhesive paper cards are used, then notes can be attached to surfaces, but they are not resistant to water, moisture, and dirt
Solution Approach 1:
The patent uses a composite structure combining micro suction cups with a washable surface material. The suction cup mechanism provides water and moisture resistance by creating a physical seal, while the surface can be cleaned without damaging the adhesion mechanism. This composite approach maintains adherence reliability even after exposure to water and dirt.
Solution Approach 2:
The patent enables self-cleaning of the support surface. The micro suction cup structure allows the support to be washed with soap and water to remove dirt and markings, and the adhesion performance is restored through simple rinsing. The system serves itself by maintaining adhesion capability after self-cleaning, without requiring replacement or special treatment.
4Area of stationary object
If conventional self-adhesive paper cards are used, then notes can be attached to surfaces, but the adherent area is relatively small compared to the back surface of the card
Solution Approach 1:
The patent segments the adhesion function into numerous micro suction cups distributed across the entire back surface of the note support. Instead of one large adhesive area, thousands of small suction cup units work in parallel. This segmentation allows the full surface area to contribute to adhesion, dramatically increasing the effective adherent area while maintaining strong overall attachment.

Function Achieved in This Case
Enables multiple uses by maintaining adhesive properties and resisting dirt, extending the useful life and making the device environmentally friendly, suitable for collaborative methods like Kanban and resistant to water and moisture.
Implementation Method 1
The micro suction cups facilitate the adherence of the flat laminar body both on surfaces that are smooth and surfaces with a certain degree of roughness

AI summary
A self-adhesive and reusable support for notes is disclosed. The support comprises a flat laminar body (1-1′-1″) that in turn comprises a first flat surface (10) and a second flat surface (11) opposite from the first surface. The flat laminar body comprises micro suction cups (3) distributed in a staggered pattern on the first flat surface and a writable surface (4) on the second surface. The self-adhesive and reusable support for notes is manufactured from opaque polymeric calendered vinyl. The support is reusable, meaning that it can be used as many times as desired, without the risk of losing the self-adhesive properties thereof even when the location thereof is constantly changed, as well as writing with marker or highlighter and erasing it again. Due to the nature thereof, it is especially suitable for use in the Kanban method.
