Floating Disk Drain Trap for Reliable Odor Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain systems fail to effectively prevent the escape of gas or odor from drains such as shower or floor drains, leading to unpleasant odors and potential health hazards.
Innovation Solution
A drain trap design comprising an outer part with a circumferential wall and an inner part that engages with the outer part, featuring radial threads and openings, along with a floating disk or rounded structure within the well to trap and retain fluid, creating a barrier against odors.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional drain system is used, then the structure is simple, but gas or odor can escape from the drain
Solution Approach 1:
The drain trap is divided into multiple components: an outer part with a well, an inner part with openings, and a floating disk structure. This segmentation allows each component to perform a specific function while collectively preventing odor escape through the P-trap mechanism and floating disk seal.
Solution Approach 2:
The inner part is nested within the outer part, with the inner part's lower end positioned inside the outer part's well. The floating disk structure is retained within the well, creating a nested configuration that maximizes space utilization and ensures proper functioning of the odor barrier.
2Reliability
If a floating disk structure is added to seal against the inner part lower end, then odor prevention is improved, but device complexity increases
Solution Approach 1:
The floating disk structure automatically adjusts its position based on fluid level in the well. When fluid enters the well, the disk rises to seal against the inner part lower end, creating an odor barrier without requiring external control mechanisms. This self-regulating feature improves reliability while minimizing complexity.
Solution Approach 2:
The floating disk structure changes its vertical position parameter in response to fluid level changes in the well. This parameter change allows the disk to make contact with the inner part lower end when needed, dynamically adjusting the seal effectiveness based on operational conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively traps and retains fluid, preventing odors from escaping through the drain by utilizing a floating disk or rounded structure that seals against the inner part lower end, ensuring a secure odor barrier.
Implementation Method 1
a flat disk structure retained within the well that is configured to float in the fluid

AI summary
A drain trap includes an outer part including a circumferential wall, the outer part extending in an axial direction between an outer part upper end and an outer part lower end, the outer part including outer part radial threads proximate the outer part upper end, the outer part lower end forming a well configured to trap and retain fluid, the outer part further including at least one opening disposed in the circumferential wall, an inner part, and a flat disk structure retained within the well. Fluid entering the drain trap accumulates in the well, and the fluid entering the drain trap is expelled from the drain trap through the at least one opening disposed in the circumferential wall.
