Membrane Bottle Dispenser for Thick Fluids With Solid Ingredients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensers fail to effectively handle thick consumable fluids with solid ingredients, as the solid particles tend to clog the dispenser mechanism and obstruct fluid flow.
Innovation Solution
A dispenser design featuring a membrane that allows flow from the bottle to the hopper while preventing backflow, accommodating solid ingredients up to a certain size, and an ergonomic design for easy use, including a collar for secure attachment to a bottle and a hopper with a conical flare for comfortable pouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional dispenser is used to pour low viscosity fluids, then the dispenser works effectively for alcohol and similar fluids, but it clogs when used with thick fluids containing solid particles
Solution Approach 1:
The dispenser is divided into separate functional components: a bottle holder for containing the thick fluid, a membrane filter for separating solid particles, and a dispensing mechanism for controlled pouring. This segmentation allows each component to be optimized for its specific function, enabling the system to handle thick fluids with solid particles that would clog conventional single-structure dispensers
Solution Approach 2:
A membrane filter is introduced as an intermediary component between the bottle and the dispensing mechanism. This membrane allows the thick fluid to pass through while blocking solid particles, preventing clogging of the dispensing mechanism. The membrane acts as a mediator that separates the fluid from the solid ingredients, enabling reliable operation with viscous fluids containing particulate matter
2Ease of operation
If the membrane allows solid ingredients to pass through, then thick fluids with solid particles can flow from bottle to hopper, but backflow of liquid to the bottle must be prevented
Solution Approach 1:
The membrane filter is designed to be dynamic rather than static - it flexes and deforms in response to pressure changes. During dispensing, the membrane allows fluid and solid particles to pass from the bottle to the hopper. When backflow pressure occurs, the membrane deforms to close the passage, preventing liquid from returning to the bottle. This dynamic response enables the system to automatically adapt to flow direction changes without mechanical valves or complex control mechanisms
3Ease of operation
If the hopper is positioned outside the bottle for ergonomic pouring, then hand grip and pouring comfort are improved, but the structure becomes more complex
Solution Approach 1:
The hopper is merged with the bottle holder structure, forming an integrated assembly. The hopper is positioned at the top of the bottle holder, creating a unified structure that provides ergonomic pouring capability while maintaining structural simplicity. This merging eliminates the need for separate, complex positioning mechanisms, as the hopper-bottle holder integration naturally achieves the desired ergonomic configuration
