Single-Dose Adhesive Dispenser with Bellows and Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dispensing adhesive cleaning agents in bathrooms are prone to inefficiency, hygiene issues, and high manufacturing costs due to design complexities and the difficulty in delivering precise doses, leading to either excessive or insufficient application.
Innovation Solution
A single-dose device featuring a hollow bellows body with a removable cap and tear-off dividing wall, allowing for easy, hygienic application of adhesive fluid substances with a spacer element for precise dosing and simple manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rigid cake of soap devices are used, then cleaning agent can be hung inside WC, but the device can be dislodged easily and end up in incorrect position
Solution Approach 1:
The invention uses a disposable single-dose device that is used once and then discarded, eliminating the need for repositioning or reuse. The device is designed for single-use application where the entire unit (container + applicator + cleaning agent) is thrown away after one application, ensuring no repositioning issues and maintaining hygiene.
Solution Approach 2:
The invention merges the container, applicator, and cleaning agent into a single integrated device. The applicator tip is directly connected to the container, and the cleaning agent is pre-loaded inside, creating a unified single-use device that eliminates the need for separate hanging mechanisms and reduces the risk of dislodgement.
2Quantity of substance
If cages with large meshes are used, then water flush can cover the rigid cake of soap, but the cleaning agent is not completely used and waste occurs
Solution Approach 1:
The single-dose device is designed to be completely consumed in one application. The container is collapsible as the cleaning agent is dispensed, allowing nearly 100% of the cleaning agent to be used. After one use, the entire device is discarded, eliminating waste from partial consumption or escape of the cleaning agent.
Solution Approach 2:
The invention changes the physical state and containment method of the cleaning agent from a rigid cake in a mesh cage to a viscous fluid in a collapsible container. This allows the cleaning agent to be completely dispensed through the applicator tip during a single application, ensuring full utilization and eliminating waste.
3Measurement precision
If syringe-shaped applicators with toothed systems are used, then preset doses can be dispensed, but the device complexity and manufacturing costs increase
Solution Approach 1:
The single-dose device is designed as a simple, disposable unit that requires no complex dosing mechanisms. The container is pre-filled with a specific amount of cleaning agent, and the user simply needs to press the plunger to dispense the entire contents through the applicator tip. This eliminates the need for toothed systems, pistons, or other complex mechanical dosing components.
Solution Approach 2:
The invention extracts the complex toothed dosing system and piston mechanism from the applicator design. Instead, it uses a simple pressurized container where the cleaning agent is forced out through the applicator tip by direct pressure from the plunger, achieving dose precision through the pre-filled quantity rather than mechanical control.
4Productivity
If caps or closing systems are used to preserve remaining substances, then multiple doses can be dispensed, but the preservation of hygienising substances is not guaranteed
Solution Approach 1:
The invention is designed as a single-dose device that is used once and then discarded. The container is sealed until use, then opened and completely consumed in one application. This eliminates the need for caps or closing systems that would be required for multi-dose devices, as the entire device is thrown away after one use, guaranteeing preservation of the hygienising properties until application.
