Solution Overview

Problem

Existing floorboard connection systems fail to provide a reliable and efficient method for aligning and connecting adjacent floorboards in a common plane while effectively managing water drainage and allowing for easy detachment.

Innovation Solution

A floorboard with a rectangular tubular hollow profile featuring cantilevered webs on its edges, including a drip ledge and water drainage channel, which allows for pivoting and snapping connections between adjacent boards, ensuring vertical alignment and efficient water drainage through a combination of offset water drainage channels and snap channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a spring clamp connection system is used to join adjacent floorboards, then vertical alignment is achieved, but the connection is difficult to detach

Engineering Contradiction:
Improvevertical alignmentVSAvoiddetachment
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection system is divided into separate functional elements: an upper connecting element for alignment and a lower connecting element for secure attachment. The upper element features a spring-loaded clamp mechanism that provides vertical alignment during installation, while the lower element provides a snap-fit connection for secure attachment and easy detachment. This segmentation allows each element to specialize in one function, resolving the contradiction between stable alignment and easy detachment.

Inventive Principle:
Principle #1Segmentation

2Strength

If multiple projecting webs are used for connection, then connection strength is improved, but device complexity increases

Engineering Contradiction:
Improveconnection strengthVSAvoidnumber of webs
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The upper and lower connecting elements are merged into a single integrated component that performs both alignment and connection functions. Instead of using separate upper and lower webs as distinct parts, the invention combines them into one piece with an upper portion featuring a spring clamp and a lower portion featuring a snap-fit mechanism. This merging reduces device complexity while maintaining connection strength through the combined action of both functional regions.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If a flat rectangular hollow tube profile is used, then manufacturing is simplified, but water drainage capability is reduced

Engineering Contradiction:
Improveextrusion processVSAvoidwater accumulation
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The connection elements extend in multiple spatial dimensions beyond the simple flat rectangular profile. The upper connecting element projects upward from the top surface with vertical spring-loaded arms, while the lower connecting element projects downward from the bottom surface with snap-fit features. This multi-dimensional configuration maintains the simple extruded hollow tube profile for manufacturing while creating dedicated pathways and channels for water drainage in both upward and downward directions, preventing water accumulation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Enables secure and detachable connection of floorboards while maintaining vertical alignment and effective water drainage, ensuring the tops and bottoms are flush and allowing for easy installation and maintenance.

Implementation Method 1

The middle web is curved in an arc shape in a transverse direction of the floorboard... The middle web is elastically designed as a vertically springy web... resiliently presses the snap bead into the snap groove

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

The drip edge and the water drainage channel run lengthwise along the floorboard... Water that runs across the top of the floorboard, perpendicular to its surface, flows over the drip edge into the drainage channel

Methodology Applied
Scientific EffectGravity: Gravitation
