Segmented Priming Pump for Canister Fluid Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art canister filters require multiple pumping actions to expel air, making the priming process slow and time-consuming.
Innovation Solution
A cylinder-like priming pump with a piston-like structure that allows for a single pull-and-push motion to expel air from the system, enabling faster and easier priming, which can be automated for even quicker operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a traditional priming pump with valve is used, then the pump can expel air from the system, but multiple pumping actions are required making the process slow and time-consuming
Solution Approach 1:
The priming chamber is segmented into distinct regions: a priming chamber separated from the filter housing, with the piston moving within the priming chamber to create pressure differentials that expel air through separate pathways (intake tube and outlet tube), enabling complete air removal in one action
Solution Approach 2:
The piston is pre-positioned and the priming chamber is pre-configured with fluid connections to the intake and outlet tubes. When the user activates the priming mechanism, the piston immediately begins moving to create the necessary pressure differential, eliminating the need for multiple incremental pumping actions
2Ease of operation
If multiple pumping actions are used to expel air, then air can be removed from the system, but the process becomes complex and requires repeated user intervention
Solution Approach 1:
The priming function is extracted from the main filter housing into a separate priming chamber with its own piston mechanism. This allows the priming operation to be performed independently and completely in one action, removing air from the system without requiring repeated interventions in the main filtration process
3Ease of manufacture
If a simple valve-based priming pump is used, then the structure is simple to manufacture, but it requires multiple pumping actions to achieve proper priming
Solution Approach 1:
The priming mechanism uses a dynamic piston that moves within the priming chamber to actively create pressure differentials, rather than relying on passive valve operation. This dynamic action enables complete air expulsion in a single motion, significantly increasing priming speed while maintaining manufacturing simplicity through the use of basic mechanical components

Function Achieved in This Case
The new priming pump significantly reduces the time and effort required to prime canister filters, enhancing their efficiency and ease of use while being simpler and cheaper to manufacture.
Implementation Method 1
a piston that can be moved through the chamber by a handle that is accessible outside the canister
Implementation Method 2
the air bubbles in the canister are pushed out and the fluid enters the canister to allow the filtration pump to work properly

AI summary
The present invention covers systems and methods for priming a canister fluid filtration system. It utilizes the push and pull caused by the movement of a piston of a priming pump between two openings in the chamber of the priming pump, to push the air out of the canister and introduces fluid into it, thereby achieving the purpose of priming the fluid filtration system.
