Solution Overview
Problem
Existing adhesive strips for attaching decorative objects to vertical surfaces require excessive force for removal, which can damage the wall, and are not intuitive or ergonomically efficient.
Innovation Solution
A decorative object assembly featuring a flexible planar strip with a removable adhesive and a non-adhesive gap section, allowing for gradual removal with a horizontal pulling force, reducing wall damage and enabling intuitive and ergonomic removal.
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 securely attached, but excessive force is required for removal which can damage the wall
Solution Approach 1:
The adhesive strip is divided into multiple segments: a first adhesive segment attached to the decorative object, a flexible intermediate segment, and a second adhesive segment attached to the wall. This segmentation allows the strip to flex and peel gradually during removal, distributing the force over time and space rather than requiring a single large pull force that would damage the wall.
Solution Approach 2:
The flexible intermediate segment changes its physical state during removal by flexing and peeling, transitioning from a taut state to a curved state. This parameter change in the strip's configuration allows it to absorb removal forces through elastic deformation, reducing the peak force transmitted to the wall and preventing 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 cause wall damage
Solution Approach 1:
The adhesive strip is segmented into multiple sections that detach sequentially rather than simultaneously. The flexible intermediate segment acts as a hinge that allows the strip to peel progressively from one end to the other, enabling easy removal with minimal force distributed over time rather than a single strong pull.
3Object-affected harmful factors
If a prior art model with flexible strips and removable adhesive is used, then removal force can be reduced, but the removal process is not intuitive or ergonomically efficient
Solution Approach 1:
Instead of requiring the user to peel the adhesive strip directly from the wall in an awkward manner, the invention inverts the approach by allowing the flexible intermediate segment to be pulled and flexed first, which naturally initiates the peeling process. This inverted sequence makes the removal motion more intuitive and ergonomic, resembling a natural pulling motion rather than a forced peeling action.
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 allows for the decorative object to be removed with minimal force on the wall, reducing the risk of damage and providing an intuitive and ergonomic removal process.
Implementation Method 1
A flexible planar strip made of a thermoplastic polymer... allows the removable adhesive to be removed from a vertical surface gradually, through application of a horizontal pulling force on the bottom of the decorative object

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.
