Solution Overview

Problem

Existing corner seal solutions for building constructions are complex and often lead to confusion for installers, resulting in suboptimal sealing due to the need for multiple types of corner seals for different installation scenarios.

Innovation Solution

A corner seal design featuring a first membrane section with a bottom and upright walls, and a second membrane section that extends parallel to the upright walls, allowing the corner seal to be transformed with a single cut into different configurations suitable for various installation scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of corner seals are supplied for different installation scenarios, then sealing adaptability is improved, but device complexity and installer confusion increase

Engineering Contradiction:
Improvesealing adaptabilityVSAvoidcorner seal variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The corner seal is designed with a universal structure that can function in multiple installation scenarios. The membrane section can be configured to seal corners between floor and walls, or between floor and recesses, eliminating the need for different corner seal types while maintaining sealing effectiveness across various building construction configurations

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple types of corner seals are supplied for different installation scenarios, then sealing adaptability is improved, but ease of operation deteriorates due to installer confusion

Engineering Contradiction:
Improvesealing adaptabilityVSAvoidinstallation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The corner seal employs a universal design that performs multiple sealing functions with a single product type. The membrane section's flexible configuration allows it to adapt to different corner geometries and installation scenarios, enabling installers to use the same corner seal for various applications without confusion or the need to select from multiple specialized types

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If corner seals are cut to fit specific situations, then adaptability is improved, but sealing reliability deteriorates

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidsealing reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The corner seal incorporates a membrane section that can be segmented or divided into different configurations through controlled cutting. This segmentation allows the single corner seal type to be adapted to various installation scenarios while maintaining proper sealing function, as the membrane sections can be arranged to seal different corner geometries without compromising the integrity of the waterproofing system

Inventive Principle:
Principle #1Segmentation
