Soluble Toilet Applicator Stick for Hygienic Self-Adhesive Detergent Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-adhesive detergent compositions for sanitary elements, such as toilets, often require complex applicators that are difficult to manufacture, unhygienic, and lead to ecological issues due to material waste, while also posing risks of chemical contamination and requiring manual handling and removal.
Innovation Solution
A soluble applicator made from materials like glucose, sucrose, and polyvinyl alcohol, with a grip portion and curved arms, that dissolves in fewer than 50 flushes, allowing single-handed application without direct contact and eliminating the need for post-application removal, using environmentally friendly and cost-effective materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex applicator device with tubular body and plunger is used to dispense detergent material, then controlled unitized doses can be achieved, but the device becomes complex to manufacture and unhygienic for repeated use
Solution Approach 1:
The patent employs a disposable applicator stick that is discarded after a single use, eliminating the need for complex reusable mechanisms with plunger and tubular body. The stick contains pre-measured detergent composition in a self-adhesive form, providing controlled dosing without requiring complex manufacturing or repeated handling that causes hygiene issues.
2Object-affected harmful factors
If a containment portion is used to prevent direct contact with detergent composition, then user safety is improved, but the containment portion must be removed after application requiring two-handed manipulation
Solution Approach 1:
The applicator stick is designed to be self-adhesive, allowing it to attach directly to the toilet surface without requiring a separate containment portion. The stick's adhesive properties enable it to remain in place during application and dissolve automatically with the first flush, eliminating the need for manual removal and two-handed manipulation.
3Ease of operation
If a deformable container applicator is used to dispense detergent product, then no support removal is needed, but the applicator itself must be removed after application causing ecological problems
Solution Approach 1:
The applicator stick is designed to change its physical state from solid to dissolved form through contact with water. This parameter change allows the stick to serve its application function and then automatically dissolve with the first flush, eliminating the need for manual removal and preventing ecological problems associated with disposable plastic applicators.
4Strength
If solid substrates are used to provide detergent composition, then the composition can be adhered to the wall, but both substrates must be removed before use adding manipulation steps and material waste
Solution Approach 1:
The invention extracts and eliminates the need for removable solid substrates by using a self-adhesive applicator stick that attaches directly to the toilet surface. The stick contains the detergent composition in self-adhesive form, allowing direct application without requiring removal of supporting substrates before use.
