Drain Adapter Compression Seal for Easy Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain adapters are difficult to install and require high force to mount due to tight seals, making them cumbersome and prone to unintentional loosening.
Innovation Solution
An adapter with a base part, sealing ring, and compression ring that allows for easy installation by using a clearance fit and a compression ring to deform the sealing ring, creating a secure, detachable connection through a press-fit mechanism and threaded connections with bayonet locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seal material is made harder and the fit is tighter to improve sealing reliability, then the sealing effectiveness is improved, but the difficulty of mounting the adapter increases
Solution Approach 1:
The sealing system is divided into two distinct components: a static seal element integrated into the adapter body and a dynamic compression ring that can be independently adjusted. This segmentation allows the seal element to provide reliable sealing while the compression ring provides adjustable mounting pressure, resolving the contradiction between sealing effectiveness and mounting ease.
Solution Approach 2:
The compression ring is designed to be adjustable and removable, transforming a static sealing system into a dynamic one. The compression ring can be adjusted to provide the necessary mounting force during installation and then removed or loosened to facilitate maintenance and拆卸, making the mounting process easier while maintaining reliable sealing when needed.
2Reliability
If the compression force on the sealing ring is increased to improve sealing reliability, then the sealing effectiveness is improved, but the risk of unintentional loosening increases
Solution Approach 1:
The compression ring is pre-loaded during installation to create the necessary sealing force, and then locking features or friction engagement are activated to maintain this pre-compression without requiring continuous high force. This preliminary action allows reliable sealing to be achieved during installation while preventing unintentional loosening during normal operation.
Solution Approach 2:
The compression ring acts as an intermediary element between the adapter body and the sealing ring. It distributes and controls the compression force, providing stable sealing pressure without directly transmitting high forces that could cause loosening. The compression ring mediates between the need for strong sealing and the need for connection stability.

AI summary
An adapter for a drain device, for installation in a floor panel, and having a receptacle with an upper inlet opening through which waste water can flow into the drain device, and parts which can be connected in a fluidic manner to a drain pipe and the receptacle, so that waste water which has passed through the inlet opening can enter the drain pipe. To improve the sealing function, the adapter has a base part having an inner thread, a first coupling point to the drain pipe, a second coupling point to the receptacle and which couples the receptacle to the drain pipe, a sealing ring that can be installed in the base part to seal the adapter from the drain pipe, and a compression ring with an outer thread compatible to the inner thread of the base part for exerting a compressive force on the sealing ring.
