Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carpet installation methods, such as glue down, stretch-in, and cut-to-fit, face challenges like difficult removal, instability, and incompatibility with irregular or dirty surfaces, particularly in commercial and large-scale applications.
Innovation Solution
A method utilizing a double face tape with velcro-style hooks on one side and gecko tape nano fibers on the other, allowing for a releasable connection of carpet products to various surfaces, including those that are not smooth or clean, by varying the density and size of hooks and fibers for adjustable strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If double face tape is used for carpet installation, then installation cost and time are reduced, but adhesion strength is insufficient and requires absolutely smooth and dust-free surfaces
Solution Approach 1:
The invention uses a composite double-sided tape structure with hook fibers on one side and adhesive nano-fibers on the other side. The hook fibers mechanically interlock with the carpet back side while the adhesive nano-fibers provide strong adhesion to the floor surface, combining mechanical and chemical bonding mechanisms to achieve both high strength and ease of installation.
Solution Approach 2:
The tape structure employs different local properties on each side: one side has hook fibers for mechanical interlocking with the carpet, while the other side has adhesive nano-fibers for strong bonding to the floor. This local differentiation allows each side to be optimized for its specific function, achieving both strong adhesion and ease of installation.
2Stability of the object's composition
If glue down installation is used, then carpet stability is improved, but removal becomes difficult and expensive
Solution Approach 1:
The adhesive nano-fibers provide dynamic adhesion properties that allow the carpet to be firmly attached during use but easily removed when needed. The nano-fiber structure enables reversible bonding, maintaining stability during normal conditions while allowing controlled removal without damage to the carpet or floor surface.
Solution Approach 2:
The adhesion strength of the nano-fibers can be controlled by adjusting parameters such as fiber diameter, length, density, and surface treatment. This allows optimization of the balance between installation stability and removal ease, achieving firm attachment during use but controlled detachment when removal is required.
3Ease of manufacture
If regular adhesive tape is used, then installation is cheap and quick, but adhesion is insufficient and surfaces must be absolutely smooth and dust-free
Solution Approach 1:
The tape structure employs different local properties on each side: one side has hook fibers for mechanical interlocking with the carpet, while the other side has adhesive nano-fibers for strong bonding to the floor. This local differentiation allows each side to be optimized for its specific function, achieving both strong adhesion and ease of installation.
Solution Approach 2:
The adhesion strength of the nano-fibers can be controlled by adjusting parameters such as fiber diameter, length, density, and surface treatment. This allows optimization of the balance between installation stability and removal ease, achieving firm attachment during use but controlled detachment when removal is required.
