Pedicure Basin Overflow Structure for Liner-Based Sanitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pedicure basins face sanitation issues due to residual bacteria and contaminants from previous clients, and the use of liners blocks the drain, preventing efficient water temperature adjustment and causing potential overflow.
Innovation Solution
A pedicure basin design featuring a main basin with a secondary basin for overflow, where the rim of the main basin is lower to allow fluid overflow to the secondary basin, accommodating liners and ensuring sanitation while allowing for fluid drainage and temperature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a liner is applied over the pedicure basin for sanitation, then hygiene is improved, but the drain is blocked preventing complete water drainage
Solution Approach 1:
The invention divides the single basin into two separate basins: a main basin for water and a secondary overflow basin. This segmentation allows the liner to be placed only in the main basin, while the overflow basin remains liner-free to provide drainage capability. The partition wall with overflow opening creates functional separation that resolves the contradiction between sanitation (liner in main basin) and drainage (overflow to secondary basin).
Solution Approach 2:
The partition wall with overflow opening acts as an intermediary structure between the main basin and secondary basin. It allows controlled water transfer from the main basin to the secondary basin while maintaining the liner barrier in the main basin. This intermediary structure enables both sanitation (through liner) and drainage (through controlled overflow).
2Temperature
If water is added to adjust temperature in a basin with blocked drain, then temperature adjustment is improved, but overflow risk increases
Solution Approach 1:
The secondary overflow basin serves as a pre-prepared safety buffer that catches any overflow water before it can spill onto the floor. This beforehand cushioning structure allows users to add water for temperature adjustment without worrying about overflow damage, as the secondary basin is designed to accommodate excess water.
Solution Approach 2:
The invention adds a vertical dimension to the basin system by creating a tiered structure where the secondary basin sits at a lower level or is positioned to receive overflow. This dimensional arrangement provides automatic overflow protection while maintaining the ability to add water for temperature control.

AI summary
A spa chair with a novel pedicure basin is disclosed. The pedicure basin has a main basin and a secondary basin. The main basin is where the feet of the person sitting in the spa chair goes. This main basin is generally filled with water. In one embodiment, the main basin has water overflow protection through a lowered rim, directing the overflow of water to a secondary basin. This method of overflow protection is especially useful where the main basin has a liner blocking the drain hole within the main basin.
