Drain Socket Straightening Vane for Clog Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain sockets for flush toilets face issues with pipe clogging due to obstacles created by contraction steps and orifices, which hinder waste passage and siphoning efficiency, especially with large pieces of waste and misaligned toilet and pipe configurations.
Innovation Solution
The introduction of straightening vanes and guide grooves within the drain socket design to align waste with the water flow, reduce friction, and prevent clogging, while maintaining a siphon effect by optimizing channel geometry and flow dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a contraction step or orifice is provided to induce siphon effect, then siphon force is improved, but waste passage becomes difficult and pipe clogging occurs
Solution Approach 1:
The drain socket is divided into multiple functional sections: an upper section with contraction step for siphon induction, and a lower section with guide groove for waste passage. This segmentation allows each section to perform its specific function without interfering with the other, resolving the contradiction between siphon force generation and waste passage ease.
Solution Approach 2:
Different regions of the drain socket are given different geometric properties: the upper portion has a contraction step with specific dimensions for siphon effect, while the lower portion has a guide groove with smooth contours for waste flow. This local differentiation optimizes each region for its intended purpose while maintaining overall system functionality.
2Duration of action of moving object
If irregularities are provided parallel to the floor to enhance floating waste suction, then siphoning duration is improved, but device complexity increases
Solution Approach 1:
The guide groove is integrated into the lower portion of the drain socket body, merging the waste guidance function with the structural design. This eliminates the need for separate components while maintaining siphoning duration improvement, thus reducing device complexity.
3Force
If a horizontal weir section is provided to induce siphon effect, then siphon effect is achieved, but waste sticking occurs and large waste passage is hindered
Solution Approach 1:
Instead of using a horizontal weir section that creates a flat surface for waste accumulation, the invention uses a guide groove with sloped surfaces that actively direct waste downward. This inverted approach converts the problematic horizontal surface into a beneficial guiding surface that prevents waste sticking while maintaining siphon effect.

Function Achieved in This Case
This design enhances waste discharge efficiency by prolonging siphoning duration, reducing clogging risks, and enabling smooth passage of large waste pieces even when the toilet and pipe are not aligned, thus improving overall wastewater discharge performance.

AI summary
A flush toilet and a drain socket are provided that align the direction of waste passing through a drainage trap so as to prevent pipe clogging without impairing wastewater discharge performance by a siphon effect. The drain socket is for connecting an outlet of a trap drainage channel of a flush toilet unit and a drain pipe located external of the flush toilet unit. The drain socket includes a drain socket body provided with an inlet for coupling with the trap drainage channel and an outlet for coupling with the drain pipe, a siphon inducing region provided on an inner wall of the drain socket body for inducing a siphon effect, and a straightening vane provided upstream of the siphon inducing region of the drain socket body to extend from the inner wall in the inward direction of the channel.
