Pivoting Toilet Seat Overlap for Washing Device Dust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet apparatuses face issues with excessive size increase and usability deterioration due to the adhesion of foreign matter to the washing device components, while trying to suppress such adhesion.
Innovation Solution
A toilet apparatus design featuring a pivotally rotatable toilet seat that covers the washing function part from above, with a seating part and a distinctively shaped covering part to differentiate between the two, reducing the illusion of a smaller opening and enhancing usability, and incorporating a washing switch on the toilet seat for independent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the toilet seat is designed to cover the cover plate from above, then dust and dirt adhesion to the cover plate is suppressed, but the device complexity increases
Solution Approach 1:
The patent combines the cover plate (which houses the washing device) with the toilet seat structure. The cover plate is integrated into the toilet seat assembly such that when the seat is lowered, it automatically covers the cover plate from above, creating a unified structure that prevents dust adhesion without requiring separate protective components.
Solution Approach 2:
The toilet seat serves multiple functions: it provides the seating surface for users and simultaneously acts as a protective cover for the cover plate housing the washing device. This multi-functionality eliminates the need for separate protective structures, reducing overall device complexity while preventing dust adhesion.
2Area of stationary object
If the toilet seat outer edge is positioned at or inside the toilet bowl outer edge, then the size of the toilet apparatus is kept compact, but the area available for covering the cover plate is reduced
Solution Approach 1:
The patent addresses the spatial constraint by utilizing the vertical dimension. The cover plate is designed to extend upward from the base plate, allowing it to be covered by the toilet seat when lowered, while the toilet seat outer edge remains positioned at or inside the toilet bowl outer edge. This vertical arrangement enables effective coverage without increasing the horizontal footprint.

AI summary
According to one embodiment, a toilet apparatus includes a toilet bowl, a base plate, a cover plate, and a toilet seat. The base plate is provided on a rear part of the toilet bowl. A washing function part washing an ano-genital region of a human body is mounted on the base plate. The cover plate is provided on the base plate. The cover plate covers the washing function part from above. The toilet seat is provided on the toilet bowl. The toilet seat is pivotally rotatable to the toilet bowl. In a state where the toilet seat is lowered, the toilet seat is positioned in a projection range where the toilet bowl is projected upward, and covers the cover plate from above.
