Hollow Piston Dosing System for Accurate Cleaning Solution Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing systems for commercial cleaning are complex, impractical, and lead to inaccurate and inconsistent dosing of cleaning solutions on mop covers, which can result in inadequate dirt pickup, surface damage, and fiber wear, especially in clinical or clean room environments.
Innovation Solution
A structurally simple dosing system featuring a storage volume with a hollow piston that moves between two positions, allowing controlled dosing of cleaning solution, eliminating the risk of overdosing or underdosing, and utilizing a mechanically operated mechanism that avoids electrical components and complex structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a pressure plate mechanism is used to release cleaning solution from a storage tank, then cleaning solution can be released from the reservoir, but accurate dosing becomes difficult as the user presses the pressure plate
Solution Approach 1:
The hollow piston is pre-filled with a predetermined amount of cleaning solution before use. The piston is inserted into the storage tank, and the cleaning solution is transferred to the piston in advance, so that the exact dosage is already prepared before the dosing operation begins.
Solution Approach 2:
The manual pressure plate mechanism is replaced with a gravity-based automatic dispensing system. The hollow piston uses gravitational force to automatically release the predetermined amount of cleaning solution without requiring manual pressing, eliminating the imprecision caused by variable user pressure.
2Measurement precision
If a complex valve system with multiple moving parts is used to regulate cleaning solution flow, then dosing can be controlled, but the device complexity increases and cleanability deteriorates
Solution Approach 1:
The complex valve system with multiple moving parts is completely removed from the design. Instead, a simple hollow piston with a single opening at its lower end is used, which allows cleaning solution to flow out through gravity without requiring any valves, levers, or complex regulating mechanisms.
Solution Approach 2:
The hollow piston automatically dispenses the predetermined amount of cleaning solution through its simple opening without requiring any active control mechanisms. The system uses the weight of the cleaning solution itself to drive the dispensing process, eliminating the need for complex valve systems.
3Quantity of substance
If a scooping device is lifted above the cleaning solution surface to provide a specific volume, then a specific volume of cleaning solution is made available, but movement of the scoop volume leads to spattering and messy work
Solution Approach 1:
Instead of lifting the cleaning solution upward out of the storage tank (which causes spattering), the hollow piston is inverted and allowed to drain downward through gravity. The cleaning solution flows out from the lower opening of the piston in a controlled downward motion, eliminating splashing and mess.
Solution Approach 2:
The system uses gravitational hydraulic flow to dispense the cleaning solution. The hollow piston acts as a gravity-fed dispenser, allowing the cleaning solution to flow out smoothly through its weight, rather than requiring mechanical lifting that causes turbulence and spattering.
4Ease of operation
If mop covers are dipped into an open container of cleaning solution, then moistening at the place of use is achieved, but inaccurate and inconsistent amounts of detergent are applied
Solution Approach 1:
The hollow piston creates a standardized, repeatable dosing template. Each time the piston is inserted into the storage tank, it automatically transfers the exact same predetermined volume of cleaning solution, creating a consistent copy of the correct dosage amount, unlike manual dipping which varies each time.
