Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid containers with built-in pumps face challenges in manufacturing cost and efficiency due to complex structures, leading to increased costs and potential leakage issues.
Innovation Solution
A modular pump system integrated into the container's cap, featuring a cylinder, piston, sealing part, and elastic member, which allows for simplified assembly and stable pumping performance by sliding the container main body to control fluid discharge and intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pump with multiple coupled members is used to discharge fluid, then pumping performance is improved, but manufacturing cost and manufacturing time increase
Solution Approach 1:
The pump is divided into three main modules: a container main body for fluid storage, a cap with an integrated pump mechanism, and a housing with outlet. This segmentation allows each module to be manufactured separately and then assembled, reducing overall manufacturing complexity while maintaining pumping performance.
Solution Approach 2:
The pump mechanism is nested within the cap structure, which itself is coupled to the container main body. The piston moves within the container main body while the pump mechanism remains integrated in the cap, creating a nested arrangement that reduces the number of external connections and simplifies the overall structure.
2Reliability
If a pump with multiple coupled members is used to discharge fluid, then pumping performance is improved, but manufacturing time increases
Solution Approach 1:
The pump mechanism is pre-assembled within the cap as an integrated unit before final assembly with the container main body and housing. This preliminary assembly of critical pump components ensures proper alignment and connection while reducing the time required for final assembly operations.
3Ease of manufacture
If the container main body slides to control fluid discharge, then manufacturing cost is reduced, but sealing requirements increase
Solution Approach 1:
A flexible sealing ring is provided that moves together with the piston during the sliding of the container main body. This flexible sealing element maintains the seal between the piston and the container wall while accommodating the relative motion, preventing fluid leakage without requiring complex sealing mechanisms.
