Wall hanging decorative assembly having a flexible strip with removable adhesive and a non-adhesive gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive strips for attaching decorative objects to vertical surfaces require excessive force for removal, leading to potential wall damage, and are not intuitive or ergonomic in their removal process.
Innovation Solution
A decorative object assembly with a flexible planar strip divided into sections: a lower section with an attachment mechanism, an upper section with removable adhesive, and a gap section without adhesive, allowing for gradual removal with a horizontal pulling force, reducing the force exerted on the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a typical adhesive strip is used to attach decorative objects to walls, then the decorative object can be firmly attached to the wall, but excessive force is required for removal which may cause wall damage
Solution Approach 1:
The adhesive strip is segmented into three distinct sections: a first permanent adhesive section for strong wall attachment, a flexible solid strip section in the middle, and a second removable adhesive section for controlled removal. This segmentation allows the different sections to perform different functions - the permanent adhesive provides strong attachment while the removable adhesive enables damage-free removal.
Solution Approach 2:
The flexible solid strip acts as an intermediary element between the permanent adhesive and the removable adhesive. This intermediary component allows for the transition from strong permanent attachment to controlled removable attachment, enabling the decorative object to be firmly fixed during use but easily removed without damage.
2Ease of operation
If the entire adhesive surface is pulled simultaneously from the wall, then the decorative object can be removed, but a strong pull force is required that may lead to wall damage
Solution Approach 1:
The adhesive strip is divided into permanent and removable sections, allowing the removal process to occur progressively from one end to the other rather than requiring simultaneous detachment of the entire adhesive surface. This progressive removal reduces the peak force required and prevents wall damage.
Solution Approach 2:
The removable adhesive section is positioned to allow preliminary engagement during removal - the user can initially pull on this section to begin the detachment process gradually, rather than needing to overcome the full adhesive strength of the entire strip at once.
3Ease of operation
If a flexible strip with removable adhesive is used, then easier removal is possible, but it is not intuitive or ergonomically efficient to bend and position only a small portion for removal
Solution Approach 1:
Different sections of the adhesive strip have different adhesive properties - the first section has permanent adhesive for strong attachment, while the second section has removable adhesive for easy detachment. This local differentiation in adhesive quality allows the entire strip to be manipulated intuitively while enabling simple removal through the designated removable section.
Solution Approach 2:
Instead of requiring the user to bend and position only a small portion of the flexible strip for removal (as in prior art), the invention inverts the approach by making a substantial portion of the strip (the second removable adhesive section) specifically designed for intuitive removal, eliminating the need for complex manipulation.
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 assembly enables easy, intuitive, and ergonomic removal of decorative objects from vertical surfaces with minimal force, minimizing the risk of wall damage while maintaining strong attachment.
Implementation Method 1
A flexible planar strip is made of a thermoplastic polymer, and defines an upper edge parallel to the upper edge of the block, a lower edge parallel to the lower edge of the block, and a vertical direction between the upper and lower edges
Implementation Method 2
A first layer of adhesive extends vertically downward from the upper edge of the strip, for releasable attachment to the vertical surface

AI summary
A decorative object assembly for attachment to a vertical surface includes a substantially planar decorative block defining an upper edge and a lower edge. A flexible planar strip is made of a thermoplastic polymer, and defines an upper edge parallel to the upper edge of the block, a lower edge parallel to the lower edge of the block, and a vertical direction between the upper and lower edges. A first layer of adhesive extends vertically downward from the upper edge of the strip, for releasable attachment to the vertical surface. An attachment mechanism for attachment to the decorative block is configured on a lower vertical section of the planar strip. A gap section of the strip is vertically located between the first layer of adhesive and the lower vertical section, on which no adhesive is adhered.
