Solution Overview

Problem

Existing methods for temporarily adhering carpets to building floors using double-sided adhesive tapes face issues such as uneven carpet width, adhesive tape protrusion, and increased risk of tripping, along with high costs and inaccuracy in pressure distribution, which affect the carpet's stability and adhesive surface.

Innovation Solution

A device with a support frame equipped with a feed section, processing section, and winding section, featuring adjustable pressure rollers, sensor means for distance detection, and displacement units to ensure even adhesive tape application, and optional cutting means to standardize carpet width, enhancing adhesive surface contact and reducing tape usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is manually applied to the carpet edges, then the carpet can be temporarily fixed to the floor, but the adhesive tape may protrude or misalign, creating tripping hazards and reducing adhesive effectiveness

Engineering Contradiction:
Improvecarpet stabilityVSAvoidadhesive tape alignment
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The device enables self-service automated application of adhesive tape through the support plate with integrated adhesive tape feed elements that automatically feed and apply tape to the carpet edges without manual intervention, ensuring consistent alignment and eliminating tripping hazards

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical application process with an automated system using sensor means to detect carpet edges and adhesive tape feed elements to precisely apply the tape, substituting human operation with automated sensing and actuation mechanisms

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

2Area of stationary object

If wide adhesive tape is used to ensure adequate adhesive surface, then the adhesive contact area increases, but the cost of adhesive tape increases

Engineering Contradiction:
Improveadhesive surface areaVSAvoidadhesive tape consumption
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The device applies adhesive tape locally and precisely at the optimal positions on the carpet edges through the support plate with adhesive tape feed elements, ensuring adequate adhesive contact area is achieved only where needed rather than using excessively wide tape across the entire carpet width

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the application parameters of adhesive tape through sensor detection and automated feed mechanisms, optimizing the tape width and placement to achieve sufficient adhesive surface area while minimizing tape consumption and cost

Inventive Principle:
Principle #35Parameter changes

3Reliability

If pressure is applied manually to the adhesive tape areas, then the carpet adheres to the floor, but the pressure distribution is uneven, affecting adhesion quality

Engineering Contradiction:
Improveadhesion qualityVSAvoidpressure distribution uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The device performs self-service automated pressing through the support plate mechanism that applies uniform pressure to the adhesive tape areas automatically, eliminating the need for manual trampling and ensuring consistent pressure distribution across all adhesive points

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical pressing action with an automated support plate system that applies controlled, uniform pressure through its structure and movement, substituting uneven human foot pressure with a engineered pressure distribution mechanism

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

4Device complexity

If carpet width variations are not compensated, then the manufacturing process is simpler, but the adhesive tape alignment becomes inconsistent, leading to protrusion or gaps

Engineering Contradiction:
Improveprocessing system complexityVSAvoidcarpet width consistency
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The device incorporates sensor means that detect the actual carpet width and position in real-time, providing feedback to the adhesive tape feed elements and support plate system, which automatically adjust their positioning to maintain precise alignment despite variations in carpet width

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system is designed to be dynamic and adaptive, with movable adhesive tape feed elements and adjustable support plate positioning that can respond to and compensate for varying carpet dimensions, transforming a static fixed-position system into a flexible adaptive one

Inventive Principle:
Principle #15Dynamics

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 device ensures a stable, evenly adhered carpet with increased adhesive surface contact, reducing tape costs and minimizing tripping hazards by compensating for uneven carpet widths and improving adhesive tape alignment and pressure distribution.

Implementation Method 1

The pressure method using the pressure rollers increases the absolute adhesive surface of the adhesive tape, since the even pressure pushes the stretch adhesive tape into the generally rough underside of the carpet, allowing the stretch adhesive tape to creep into the rough surface.
