Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for finishing the edges of carpets and hard surface flooring are unsightly, hazardous, or messy, and fail to provide a durable and visually appealing solution to prevent fraying and damage.

Innovation Solution

A flexible strip with a hinge and adhesive is used to securely and discreetly conceal the raw edge of flooring, featuring a gap or reduced adhesive in the hinge area for easy application and automated binding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If large metal staples are used to prevent fraying, then the edge binding function is achieved, but the appearance becomes unsightly and hazardous

Engineering Contradiction:

Improveedge binding durabilityVSAvoidvisual appeal and safety

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces permanent metal staples with a self-adhesive tape that can be easily applied and removed without damage to the flooring material. The tape provides temporary yet effective edge binding that maintains appearance and safety while fulfilling the protective function.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The self-adhesive tape is designed to match the color of the flooring material, making the edge binding invisible or aesthetically pleasing. This resolves the contradiction by maintaining the protective function while eliminating the unsightly appearance of metal staples.

Inventive Principle:

Principle #32Color changes

2Reliability

If heavy yarn stitching is used to bind the edge, then the fraying prevention is achieved, but the appearance becomes inelegant and the equipment cost increases

Engineering Contradiction:

Improveedge binding durabilityVSAvoidvisual appeal

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces expensive heavy-duty sewing machines and yarn stitching with a simple self-adhesive tape that can be applied manually or with minimal equipment. This eliminates the need for expensive equipment while providing effective edge binding that maintains visual appeal.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The self-adhesive tape is color-matched to the flooring material, creating an elegant appearance that eliminates the inelegant look of heavy yarn stitching while maintaining the same protective function.

Inventive Principle:

Principle #32Color changes

3Reliability

If adhesive is applied to bind the edge, then the binding function is achieved, but the application process becomes messy and displeasing

Engineering Contradiction:

Improveedge binding durabilityVSAvoidapplication cleanliness

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the adhesive function into a pre-applied self-adhesive tape, separating the adhesive application process from the edge binding process. This eliminates the messiness of applying adhesive to the edge while maintaining effective binding, as the adhesive is already cleanly applied to the tape backing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adhesive is applied in advance to the tape backing during manufacturing, rather than being applied at the time of edge binding. This preliminary action eliminates the messiness of adhesive application during installation while ensuring reliable edge binding.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If conventional edge finishing methods are used, then some binding function is achieved, but the installation process is time-consuming and labor-intensive

Engineering Contradiction:

Improveedge binding durabilityVSAvoidinstallation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments the edge binding function into a self-contained self-adhesive tape that combines adhesive, binding, and finishing functions in one component. This eliminates multiple steps and tools needed for conventional methods, dramatically improving installation efficiency while maintaining binding durability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The self-adhesive tape is designed to be self-applying and self-finishing, requiring minimal tools or skilled labor. The tape adheres to itself when folded, eliminating the need for additional adhesive application, stitching, or specialized equipment, thereby maximizing installation productivity.

Inventive Principle:

Principle #25Self-service
