Adhesive Waterproofing Drain Connection System
Solution Overview
Problem
Existing connection systems for waterproofing with drain pipes in indoor wet areas are complex, costly, and time-consuming, often requiring mechanical elements that can compromise the waterproof seal and extend assembly times.
Innovation Solution
A system utilizing an adhesive sealing means and a securing ring for a watertight connection between a discoidal plane and a waterproofing sheet, eliminating the need for mechanical attachments, with a perimeter gasket for adjustment and a grid for supporting visible coatings, allowing for faster and more reliable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical elements (clamping rings, screw elements) are used to connect waterproofing to drain pipe, then connection strength is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent replaces mechanical connection elements (screws, clamping rings) with a chemical bonding system using adhesive composition. The adhesive is applied between the waterproofing membrane and the drain pan flange, creating a chemical bond that eliminates the need for mechanical fasteners, thereby simplifying the assembly process while maintaining connection strength
Solution Approach 2:
The patent introduces an adhesive composition as an intermediary substance between the waterproofing membrane and the drain pan flange. This adhesive layer serves as a mediator that chemically bonds the two components together, replacing direct mechanical fastening and reducing assembly complexity
2Reliability
If mechanical elements are used for connection, then connection reliability is improved, but assembly time is increased
Solution Approach 1:
By substituting mechanical fastening with adhesive bonding, the patent eliminates the time-consuming steps of positioning and securing mechanical elements. The adhesive application and bonding process is faster and eliminates assembly delays while maintaining connection reliability through proper adhesive selection and application procedures
3Strength
If mechanical elements are used for connection, then connection strength is improved, but cost of the system increases
Solution Approach 1:
The patent extracts and removes mechanical connection elements (screws, clamping rings, washers) from the assembly, retaining only the essential adhesive bonding system. This reduction in components simplifies the overall system while maintaining the necessary connection strength through proper adhesive formulation and application
Solution Approach 2:
The patent merges the connection function into a single adhesive bonding system rather than using multiple separate mechanical components. The adhesive composition integrates the functions of bonding, sealing, and stress distribution that were previously performed by multiple mechanical elements, thereby reducing the number of components and simplifying the system
