Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage systems fail to provide a tight installation of seamless floor coverings due to multiple sealing planes, leading to uneven thickness and potential cracking, especially with liquid-applied floor coverings.
Innovation Solution
A drainage device with a vertical contact surface of 1-6 mm, a support section, and a single-piece design, including a circumferential seal and a flexible sealing membrane, ensuring uniform thickness and tight sealing with liquid-applied floor coverings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sealing planes are used in existing drainage systems, then sealing capability is improved, but floor covering thickness uniformity deteriorates and cracking risk increases
Solution Approach 1:
The patent merges multiple sealing functions into a single integrated sealing plane formed by the flange. The flange creates one continuous sealing surface between the floor covering and the drainage system, eliminating the need for multiple separate sealing planes. This single sealing plane approach maintains reliable sealing while providing a uniform support surface that prevents thickness variations and cracking in liquid-applied floor coverings.
2Ease of operation
If liquid-applied floor coverings are used, then seamless installation is achieved, but tight installation becomes difficult due to multiple sealing planes
Solution Approach 1:
The flange integrates multiple sealing functions into one continuous sealing plane, creating a uniform support surface that facilitates seamless application of liquid floor coverings. This single integrated sealing structure eliminates the complexity of multiple sealing planes, allowing the liquid covering to be applied continuously without interruption while maintaining tight installation and reliable sealing.
3Reliability
If existing drainage systems with multiple sealing planes are used, then sealing is provided, but uneven thickness and potential cracking occur
Solution Approach 1:
The flange consolidates multiple sealing planes into a single integrated sealing structure that provides both reliable sealing and a uniform support surface. This unified design eliminates the thickness variations and instability caused by multiple separate sealing planes, ensuring consistent floor covering thickness and preventing cracking while maintaining effective sealing.
4Manufacturing precision
If a single-piece design with vertical contact surface is used, then thickness uniformity and tight sealing are improved, but device complexity increases
Solution Approach 1:
The flange integrates the vertical contact surface, sealing function, and support structure into a single piece, achieving thickness uniformity and tight sealing without significantly increasing device complexity. This consolidated design eliminates the need for multiple separate components and assembly steps, maintaining structural simplicity while providing the required precision and sealing performance.
