Fixing base for fixing a hinge for a toilet seat set
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting bases for toilet seat hinges can scratch or damage the toilet bowl surface and provide insufficient stability, especially under lateral distortion forces, due to direct contact and inadequate fastening mechanisms.
Innovation Solution
A mounting base with an inner adhesive element and a seating element that allows for adjustable placement and secure fixation using an adhesive layer, which includes an adhesive protection film and an elastic design to absorb weight and distribute pressure evenly, preventing surface damage and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mounting base uses a flat plate element that directly contacts the toilet bowl surface, then the structure is simple, but it causes scratching or damage to the delicate bowl surface
Solution Approach 1:
The patent introduces a mounting element as an intermediary component between the mounting base and the toilet bowl. This mounting element has a lower extension that contacts the bowl surface instead of the flat plate element, preventing direct contact and potential damage. The mounting element acts as a protective mediator that separates the mounting base from the delicate bowl surface.
Solution Approach 2:
The mounting element is made of elastic material that can be compressed when pressure is applied. This flexibility allows the mounting element to conform to the bowl surface and distribute pressure evenly, preventing scratching while maintaining secure attachment. The elastic properties enable the mounting element to deform reversibly under load.
2Ease of operation
If the mounting base is secured solely with a mounting element in an elongated hole, then installation is simple, but the attachment is not sufficiently stable against lateral forces
Solution Approach 1:
The patent combines two different attachment mechanisms: the mechanical mounting element for initial positioning and adjustment, and the adhesive inner adhesive element for permanent fixation. This hybrid approach merges the advantages of both mechanical (adjustability) and chemical (stability) attachment methods to achieve both ease of installation and reliable stability.
Solution Approach 2:
The mounting base uses composite attachment materials: an elastic mounting element material (such as foam or rubber) combined with an adhesive material. This composite approach leverages the mechanical properties of the elastic material for shock absorption and positioning, while the adhesive provides strong bonding to the bowl surface, creating a more reliable overall attachment system.
3Object-affected harmful factors
If the mounting element is made elastic to distribute pressure, then surface damage is prevented, but the structure becomes more complex
Solution Approach 1:
The patent changes the material parameter of the mounting element from rigid to elastic. This parameter change enables the mounting element to deform under pressure and distribute loads over a larger area, preventing surface damage. The elastic property allows the mounting element to adapt to surface irregularities while maintaining contact pressure within safe limits.
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
Facilitates easy assembly, prevents surface scratching, and provides additional stabilization against lateral forces by ensuring a secure attachment of the hinge to the toilet bowl using an adhesive layer and elastic elements.
Implementation Method 1
The mounting base has an inner adhesive element arranged on the underside of the plate-shaped element... The inner adhesive element allows the hinge to be attached or fixed to the toilet bowl after it has been placed on it
Implementation Method 2
The mounting element is an annular, disc-shaped elastic element... This allows irregularities or unevenness on the surface of the toilet bowl to be compensated for when attaching the hinge
