Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensing systems for liquids like shampoo and dishwashing liquid result in residual fluid waste and environmental harm due to inefficient refilling processes and non-recyclable packaging, leading to increased waste and pollution.
Innovation Solution
An eco-friendly pumping device utilizing a vacuum principle with a press pumping unit, a replaceable soft bag, and a bottle, where the pump cylinder and duct create a sealed space within the bag to extract fluid completely without residue, using fastening mechanisms for easy assembly and replacement, and sealing elements to maintain airtightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional dispensing systems are used to extract fluid from bottles, then convenience of use is improved, but fluid waste increases due to residual material remaining in the bottle
Solution Approach 1:
The patent employs a vacuum pumping mechanism that utilizes pneumatic pressure differential to extract fluid from the bottle. The pump creates negative pressure (vacuum) that draws fluid through the dispensing system, enabling complete extraction of fluid material from the bottle without manual pouring, thus eliminating residual waste while maintaining ease of operation.
Solution Approach 2:
The system changes the pressure parameter within the bottle by creating a vacuum environment. This parameter change enables the fluid to be drawn out completely through the dispensing head, allowing 100% extraction of the fluid material and preventing the residual waste that occurs with conventional gravity-based dispensing systems.
2Loss of substance
If manual refilling of bottles from refill packages is performed, then waste of containers is reduced, but fluid smearing and mess increase requiring additional water for cleaning
Solution Approach 1:
The system enables self-service refilling where the vacuum pump automatically draws fluid from the refill package into the bottle without manual intervention. The vacuum pressure differential causes fluid to transfer through the connected ducting system automatically, eliminating the need for manual pouring and the associated mess and cleaning requirements.
Solution Approach 2:
The patent introduces a vacuum-mediated transfer system that acts as an intermediary between the refill package and the bottle. The vacuum pump and ducting system serve as the intermediary mechanism that transfers fluid cleanly without direct contact, preventing fluid smearing on hands and surfaces while enabling container reuse.
3Object-affected harmful factors
If refill packages are used to reduce container waste, then environmental protection is improved, but residual fluid in refill packages becomes hard to recycle and may pollute the environment
Solution Approach 1:
The vacuum pumping system enables continuous and complete fluid extraction from the refill package until the container is entirely empty. The system maintains vacuum pressure throughout the refilling process, ensuring that even the last drops of fluid are transferred to the bottle, leaving no residual waste in the refill package that would require disposal or recycling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device allows for complete fluid usage without waste, reduces environmental impact by being reusable, and simplifies the refilling process by eliminating direct contact with the fluid, thus enhancing eco-friendliness and operational efficiency.
Implementation Method 1
the interior of the replaceable soft bag forms a negative pressure state, so that the fluid material is capable of being outputted through the duct by a vacuum effect
Implementation Method 2
When the dispensing head of the press pumping unit is pressed, the pump cylinder is capable of producing a drawing force

AI summary
An eco-friendly pumping device includes a press pumping unit (1), a bottle (3), and a replaceable soft bag (2) disposed in the bottle (3). An opening part (22) of the replaceable soft bag is directly connected to the press pumping unit (1). The interior of the replaceable soft bag forms a closed space and a negative pressure state simultaneously when operating the press pumping unit (1) because of vacuum effect. A shape and an inner volume of the flexible bag body (21) are squeezed automatically by external air pressure outside because of vacuum effect as the time of use and amount of use increase. The replaceable soft bag (2) can be directly fastened to the press pumping unit (1) to replace an empty one, so that the fluid material in the replaceable soft bag (2) does not need to be poured and transferred into the bottle (3), and the fluid material does not contact with hands.
