Shower Drain Adapter With Bonding Flange for Watertight Membranes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tile installers face challenges in adapting conventional two-piece shower drain systems for use with bondable waterproof membranes, as existing drain fittings do not allow for a secure, watertight connection, requiring costly replacements or changes in installation methods.
Innovation Solution
A shower drain adapter with a lower mating flange and integrated bonding flange is designed to couple with conventional two-piece drain systems, enabling a bondable waterproof membrane to be securely attached, providing a watertight seal and allowing for the use of bondable waterproof membranes with existing shower pan drain systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional two-piece drain systems are used, then the existing shower pan drain system can be utilized, but a secure watertight connection with bondable waterproof membranes cannot be achieved
Solution Approach 1:
The adapter serves as an intermediary component between the conventional two-piece drain system and the bondable waterproof membrane. It includes a lower mating flange that couples to the existing drain system and an integrated bonding flange that provides a secure attachment surface for the membrane, thereby enabling watertight connections without requiring replacement of the entire drain system
Solution Approach 2:
The adapter is designed to perform multiple functions: it couples with conventional two-piece drain systems, provides a bonding surface for waterproof membranes, and maintains the integrity of the existing drain architecture. This multi-functionality allows the same adapter to work with various drain configurations while enabling membrane integration
2Ease of manufacture
If conventional two-piece drain systems are used, then the existing infrastructure can be maintained, but integration with bondable waterproof membranes requires costly replacements or changes in installation methods
Solution Approach 1:
The solution segments the drain system into distinct functional components: the existing two-piece drain system remains intact, while the adapter provides the membrane integration function. This segmentation allows the membrane bonding capability to be added without replacing the entire drain system, reducing installation costs and complexity
Solution Approach 2:
The adapter is designed to be installed in advance during the shower construction process, before the final waterproofing membrane is applied. This preliminary installation ensures that the bonding flange is already in position and ready for membrane attachment, streamlining the installation process and avoiding costly retrofits

AI summary
A shower drain adapter configured to allow use of a bondable waterproof membrane with a shower pan drain system comprises a drain body and a lower mating flange extending from the drain body. The lower mating flange is operable to mate with an upper portion of a body of a shower pan drain installable on a waste pipe. An integrated bonding flange extends from the drain body and is operable to be sealably attached to a bondable waterproof membrane to provide a waterproof seal between the membrane and the adapter.
