Embedded Pump Portable Water Purifier Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable water purifiers face challenges in generating sufficient pressure for filtration, leading to long processing times, and often have large and cumbersome designs that hinder portability.
Innovation Solution
A portable water purifier design featuring a pump embedded in the side of a container, with only the top exposed, uses external air pressure to drive water purification through a filter assembly, allowing for efficient and compact operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pressurizing unit is added to generate sufficient pressure for filtration, then filtration speed is improved, but device size increases and portability deteriorates
Solution Approach 1:
The pump is merged with the container body by embedding it into a seat recessed on the side surface of the container. The pump's inlet communicates with the container's interior through a hole in the seat, integrating the pressurizing function directly into the container structure. This eliminates the need for a separate protruding pressurizing unit while maintaining filtration capability.
Solution Approach 2:
The pump is nested within the container's side wall structure. The seat recessed on the container's side surface houses the pump, with only the pump's outlet portion protruding slightly or being flush with the container exterior. This nesting approach minimizes the overall device volume while preserving the pressurizing function needed for rapid filtration.
2Volume of moving object
If a pump is embedded in the side of the container, then device portability is improved, but pressure generation capability may be compromised
Solution Approach 1:
The seat recessed on the container's side surface is specifically designed to accommodate the pump's dimensions and pressure generation requirements. The seat's geometry and the hole's positioning are optimized to allow the pump to generate sufficient pressure locally at the filtration point, ensuring that the embedded configuration does not compromise pressure generation capability.
3Volume of moving object
If the pump is fully embedded in the container, then device compactness is improved, but air supply function is limited
Solution Approach 1:
The pump is segmented such that only the necessary outlet portion protrudes from or is flush with the container's side surface. The inlet is embedded within the container through the seat and hole configuration, while the outlet remains accessible for air supply. This segmentation allows the pump to maintain a compact embedded form while preserving full operational capability for air intake and pressurization.
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
Enables quick and portable access to purified water by generating necessary pressure through external air supply, facilitating easy carrying and rapid filtration without the bulk of traditional systems.
Implementation Method 1
the pump is embedded in the seat of the container with a top exposed outside, is fixed to the container by being fitted in the hole, and keeps and then supplies external air into the container in a predetermine direction by being repeatedly deformed and restored by force repeatedly applied from the outside
Implementation Method 2
a filter assembly coupled to a bottom of the cap and inserted in the container to purify water kept in the container

AI summary
A portable water purifier according to the present invention includes: a container that is open at least at the top and has a predetermined internal volume; a cap that is coupled to the top of the container to seal the container and has an exit for selectively communicating with the container; a pump that is embedded in a side of the container and supplies air in a predetermined direction into the container; and a filter assembly that is coupled to the bottom of the cap and inserted in the container to filter water. According to the present invention, it is possible to simply supply purified water using pressure from the pump embedded in a side of the container to supply air into the container in a predetermined direction.
