Solution Overview

Problem

The installation of dovetailed interlocking flooring material is time-consuming and labor-intensive, requiring installers to be on their hands and knees to hammer interlocking tabs into place, which is inefficient and laborious.

Innovation Solution

A weighted floor roller device with a chassis, wheels, and a handle that applies pressure to interlocking tabs, reducing the need for manual hammering by using additional weights and allowing easy movement over the tiles to efficiently interlock the tabs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rubber mallet is used to hammer interlocking tabs into place, then the tabs can be connected to adjoining tiles, but the process becomes time-consuming and labor-intensive

Engineering Contradiction:

Improveconnection reliabilityVSAvoidinstallation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The flooring system uses self-laying tiles with dovetailed interlocking tabs that automatically engage when tiles are pressed together, eliminating the need for manual hammering. The tiles are designed to interlock through their geometric shape, allowing the installation process to serve itself without requiring intensive manual intervention while maintaining reliable connections

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of using a mallet to force tabs into place, the invention inverts the approach by designing tabs that passively interlock when pressure is applied from above. The pressure application method is inverted from localized hammering to distributed rolling pressure, which achieves reliable connection without the labor-intensive hammering process

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If an installer hammers each interlocking tab systematically, then full adhesion is achieved, but the process requires being on hands and knees and is laborious

Engineering Contradiction:

Improveadhesion completenessVSAvoidinstaller comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The dovetailed interlocking tabs are designed to self-align and self-engage when tiles are pressed together, eliminating the need for installers to systematically hammer each tab while on their hands and knees. The geometric design ensures complete adhesion through passive interlocking

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention inverts the traditional hammering approach by applying pressure from above using a roller device, rather than having the installer work from below by hammering. This inversion allows installers to remain in a comfortable standing position while achieving complete tab adhesion

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If a roller device with significant weight is used to press tiles together, then interlocking tabs are efficiently adjoined, but the device becomes difficult to transport and store

Engineering Contradiction:

Improvetab adhesion speedVSAvoidtransportability

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The roller device is segmented into a modular design with separable components, allowing the heavy roller body to be detached from the handle. This segmentation enables the heavy weight component to be easily transported and stored separately, while maintaining the full weight capability during the tile adhesion process

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The roller device incorporates dynamic characteristics by allowing the roller body to be detached and reattached to the handle. This dynamic configuration enables the device to transition between a heavy, stable state during operation and a lightweight, portable state during transport and storage

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 significantly reduces the time and labor required for installing dovetailed interlocking flooring, making the process more efficient and less labor-intensive by applying pressure to interlock the tabs effectively.

Implementation Method 1

The roller device has a combined weight that puts a significant amount of pressure on the interlocking tabs on the dovetailed interlocking flooring material so that the weight of the roller device efficiently and quickly adjoins the adjacent interlocking tabs

AI summary

A device provides for an efficient, fast, and less labor-intensive way of laying dovetailed interlocking flooring material which have interlocking tabs to connect adjoining flooring material. The device comprises of a chassis offering structural support to which all other elements are connected to either directly or indirectly. The chassis has an upper portion which accepts additional weight and an undercarriage portion which is configured to connect to one or more front wheels and back wheels. The front wheels are configured to put pressure along each side of the interlocking tabs, while the one or more back wheels are configured to press on the interlocking tabs, and wherein the combined weight of the device interlocks the interlocking tabs in the flooring material.
