Universal Adapter Ring for Toilet Flush Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toilet flushing control button systems require multiple adapter rings to accommodate different tank cover diameters and thicknesses, leading to increased costs and waste due to the need for unused adapters.
Innovation Solution
A single adapter ring design that can be positioned to accommodate openings of different diameters and thicknesses, allowing the control button to be adaptable to various toilet tank covers without the need for multiple rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adapter rings are provided to accommodate different tank cover diameters and thicknesses, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The adapter ring is designed with a conical shape that allows it to function universally with tank covers of different diameters (14mm, 40mm, 50mm) and thicknesses (2mm plastic, 20mm ceramic). The cone geometry enables the ring to self-adjust and make contact at appropriate positions on the cover surface, eliminating the need for multiple specialized adapter rings while maintaining full adaptability.
2Adaptability or versatility
If multiple adapter rings are provided for different opening diameters, then adaptability is improved, but loss of substance increases due to unused adapters
Solution Approach 1:
The single conical adapter ring serves multiple functions across different opening diameters and cover thicknesses. Its geometric design allows it to be positioned at different angles and depths to accommodate 14mm, 40mm, and 50mm openings, as well as both thin plastic and thick ceramic covers, ensuring that one adapter ring replaces multiple previously required rings and eliminating material waste.
3Adaptability or versatility
If a single adapter ring is used for different thicknesses, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The adapter ring employs a conical geometry where the angle and dimensions of the cone are specifically designed to accommodate variations in cover thickness. The cone angle allows the ring to self-adjust its position along the thickness dimension, making contact at the appropriate depth for both thin (2mm) and thick (20mm) covers, thereby achieving adaptability through geometric parameter optimization rather than requiring high-precision adjustable mechanisms.
