Inflatable Fluid Separator for Zero Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid treatment methods, such as the Dilution Method, require additional containers and spaces, leading to inefficiencies in time, energy, and space consumption, as they continuously dilute dirty fluids with filtered ones, failing to reach zero contamination levels.
Innovation Solution
The Non-Dilution Method employs flexible, inflatable sacks that act as separators within containers, allowing for the thorough treatment and reuse of fluids without additional space, by suctioning and releasing treated fluid, ensuring fixed time and energy consumption and complete fluid treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fluid treatment methods using additional containers are employed, then fluid treatment completeness is improved, but space consumption and device complexity increase
Solution Approach 1:
The patent implements nesting by placing a flexible sack inside the fluid container, creating a nested structure where the sack is contained within the container. This allows the treatment system to operate within the existing container volume without requiring additional external containers, thereby resolving the contradiction between treatment completeness and space consumption.
Solution Approach 2:
The patent segments the fluid container into two functional zones: the inner flexible sack that undergoes expansion and contraction for fluid treatment, and the outer container that provides structural support and housing. This segmentation allows the treatment mechanism to function effectively within the existing container space.
2Reliability
If conventional fluid treatment methods using additional containers are employed, then fluid treatment completeness is improved, but device complexity increases
Solution Approach 1:
The patent merges the treatment chamber and container into a single integrated system where the flexible sack is positioned inside the existing container. This combination eliminates the need for separate external treatment containers and reduces the number of components, thereby resolving the contradiction between treatment completeness and device complexity.
Solution Approach 2:
The flexible sack serves multiple functions: it acts as the treatment chamber, the movable element for fluid circulation, and the separator between treated and untreated fluid. This multi-functionality reduces the number of separate components needed, resolving the device complexity issue while maintaining treatment effectiveness.
3Volume of stationary object
If flexible sacks are used for fluid treatment within existing containers, then space consumption is reduced, but the complexity of fluid circulation control increases
Solution Approach 1:
The patent employs a dynamic flexible sack that expands and contracts in response to pressure changes, enabling automatic fluid circulation without complex mechanical pumps or valves. The dynamic nature of the sack simplifies the circulation control mechanism while maintaining effective fluid treatment within the existing container space.

AI summary
Tape cutters are adapted to fold the tip of a tape. The tape cutters include a cutter body configured to draw-out one end of a tape from a tape reel, which includes a base member formed of a synthetic resin film, paper, or cloth and the tape wound around the base member and having adhesive or cohesive force. A cutter is positioned at an end of the cutter body to cut the tape drawn out from the tape reel. The cutter is installed to protrude forward from the end of the cutter body and to be inclined. A space part is formed inside the cutter. A cover surface covers an adhesive surface of the tape is formed on an end of the tape by using the space part.
