Solution Overview

Problem

Current methods for finishing flooring edges, such as stapling, stitching, and gluing, are unsightly, hazardous, or messy, and require bulky equipment, lacking a compact and efficient solution for on-site or factory edge finishing.

Innovation Solution

A hand-held or table-mounted flooring edge tool with a bi-level soleplate and heating elements applies heat and pressure to simultaneously adhere a flooring edge finish to both the bottom and side surfaces, using a flooring edge finish with an adhesive and hinge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stapling, stitching, or gluing methods are used to finish flooring edges, then edge protection is achieved, but the equipment required is bulky and heavy

Engineering Contradiction:
Improveedge protectionVSAvoidequipment size
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical edge finishing methods (stapling, stitching, gluing) with a thermal bonding system. The flooring edge finish includes an adhesive layer that is activated by heat from the soleplate, eliminating the need for heavy-duty mechanical equipment while achieving reliable edge protection and finishing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional edge finishing methods are used, then edge protection is provided, but the appearance is unsightly or hazardous

Engineering Contradiction:
Improveedge protectionVSAvoidappearance quality
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The flooring edge finish is a composite structure comprising a first section with adhesive for bonding to the flooring bottom, a second section forming a vertical face for the finished edge appearance, and a hinge section connecting them. This composite design provides both protective function and aesthetic appearance, eliminating unsightly staples or stitching while maintaining edge protection.

Inventive Principle:
Principle #40Composite materials

3Reliability

If stitching is used to finish carpet edges, then edge binding is achieved, but expensive heavy-duty sewing machines are required

Engineering Contradiction:
Improveedge bindingVSAvoidequipment cost and size
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical stitching process with thermal bonding. The adhesive layer in the flooring edge finish is activated by heat from the soleplate, creating a strong bond between the finish and flooring without requiring expensive heavy-duty sewing machines or complex mechanical stitching equipment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If gluing is used to finish flooring edges, then edge protection is achieved, but the application process is messy and displeasing

Engineering Contradiction:
Improveedge protectionVSAvoidapplication cleanliness
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The flooring edge finish is segmented into distinct functional sections: a first section containing the adhesive layer for bonding, a hinge section for flexibility, and a second section forming the visible finished edge. This segmentation allows the adhesive to be contained within the structure rather than applied messily during installation, resulting in a clean application process while maintaining reliable edge protection.

Inventive Principle:
Principle #1Segmentation
