Solution Overview
Problem
Existing liquid dispensing systems, particularly in flexible containers, are pressure-dependent and lack the ability to aspirate fluid, making it difficult to achieve exact and regular dosing of liquids across various industries.
Innovation Solution
A dispenser element comprising a flexible bulb connected to a tube and one-way valves, with elastic membranes that allow for precise control of liquid dispensing, enabling the system to aspirate fluid and provide accurate dosing regardless of pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional pressure-dependent dispensing systems are used, then the system is simple in structure, but the dosing precision and accuracy deteriorate
Solution Approach 1:
A dosing chamber is introduced as an intermediary component between the container and the dispensing valve. The dosing chamber receives liquid from the container through a first valve, measures the exact required amount, and then dispenses it through a second valve. This mediator enables precise dosing while maintaining a relatively simple overall system structure.
Solution Approach 2:
The dispensing system is segmented into distinct functional components: a dosing chamber for measurement, a first valve for liquid intake, a second valve for dispensing, and a floating plunger for actuation. This segmentation allows each component to perform its specific function optimally, achieving both simplicity and precision.
2Measurement precision
If single dose chamber systems with floating plunger are used, then the system achieves better dosing control, but the device complexity increases
Solution Approach 1:
The floating plunger is integrated directly within the dosing chamber, combining the actuation mechanism and the measurement chamber into a single unified component. This merging reduces the number of separate parts while maintaining dosing control functionality.
Solution Approach 2:
The dosing chamber serves multiple functions: it acts as a measurement chamber for exact dosing, a chamber for receiving liquid from the container, and a chamber for dispensing liquid through the second valve. This multi-functionality reduces the need for separate components, simplifying the overall device.
3Ease of operation
If conventional spouts are used, then the dispensing action is simple, but the ability to dispense exact amounts of liquid deteriorates
Solution Approach 1:
The floating plunger provides visual feedback by rising in the dosing chamber as liquid is dispensed. When the plunger reaches the top of the chamber, it signals that the exact required amount has been dispensed. This feedback mechanism enables precise dosing while maintaining simple manual operation through pressure-dependent actuation.

AI summary
A container configured for housing a fluid. A compressible body disposed within the container for dispensing fluid. The compressible body is compressed by applying compression to the container. When the compressible body changes from a non-compressed state to a compressed state, the fluid within the container does not flow into compressible body and fluid within the compressible body flows out of the compressible body and when the compressible body changes from the compressed state to the non-compressed state the fluid flows into the compressible body.
