Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fixtures for laying threshold-covering profiled elements are limited in their ability to handle height differences greater than 14 mm, requiring different profiled elements for varying heights, which complicates installation and increases costs.

Innovation Solution

A fixture comprising an L-shaped insert with a dovetail-shaped coupling mechanism and adjustable blocks, combined with adhesive layers, allows the same threshold-covering profiled element to be used across different height differences by compensating for height variations and providing stable anchoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesives and anchoring blocks are used for height differences up to 14 mm, then the profiled element can be stably installed, but the solution becomes limited and requires different profiled elements for greater height differences

Engineering Contradiction:

Improveinstallation stabilityVSAvoidapplicability to different height differences

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The fixture incorporates an adjustable support block that can be positioned at different heights along the insert, allowing the same profiled element to be adapted to various height differences between flooring surfaces. This dynamic adjustment capability eliminates the need for different profiled elements for different height scenarios.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes the height parameter of the support block to accommodate different height differences between flooring surfaces. By varying the position of the support block along the insert, the system can handle height differences exceeding 14 mm while maintaining installation stability with the same profiled element.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If different profiled elements are used for greater height differences, then the maximum height difference limitation is overcome, but the device complexity and cost increase

Engineering Contradiction:

Improvehandling of various height differencesVSAvoidvariety of profiled elements required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fixture design makes a single profiled element universal for multiple height difference scenarios. The adjustable support block within the fixture provides the adaptability needed to handle various height differences, eliminating the need for multiple specialized profiled elements and reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fixture is divided into separable components including the insert, support block, and profiled element. This segmentation allows the support block to be independently adjusted to different heights while keeping the profiled element standardized, reducing the need for multiple profiled element variants.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If different profiled elements are used for different height differences, then height variations can be accommodated, but installation time and cost increase

Engineering Contradiction:

Improveaccommodation of height variationsVSAvoidinstallation speed

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The support block can be pre-positioned at the required height along the insert before installing the profiled element. This preliminary adjustment eliminates the need for custom profiled elements or complex on-site modifications, allowing for faster installation while accommodating various height differences.

Inventive Principle:

Principle #10Preliminary action
