Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensers have a complicated structure design and poor stability after assembly, leading to a reduced service life.
Innovation Solution
A simplified liquid dispenser design with a pumping structure and pressure-accumulation ejecting structure, featuring a main frame with a liquid storage cavity, piston rod, diversion channel, and guiding portion, along with snap-fitted fixing seats and arc-shaped valves for stable liquid inlet and outlet control, and a pressure relief mechanism to manage internal pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid dispenser uses a traditional pumping structure with multiple separate components, then the liquid can be pumped and ejected, but the structure becomes complicated and assembly stability deteriorates
Solution Approach 1:
The patent integrates the liquid inlet channel and liquid outlet channel directly into the main frame as diversion channels, merging previously separate components into a unified structure. This reduces the number of parts and simplifies assembly while maintaining functional integrity of the liquid pumping and ejection system
Solution Approach 2:
The main frame serves multiple functions: it provides structural support, contains the liquid storage cavity, and incorporates the diversion channels for liquid flow. This multi-functionality reduces the need for separate components, simplifying the overall structure while improving assembly stability
2Reliability
If multiple separate parts are used in the pumping structure, then the liquid inlet and outlet functions can be implemented, but the number of parts increases and assembly stability decreases
Solution Approach 1:
The liquid inlet channel and liquid outlet channel are integrated into the main frame as diversion channels, combining multiple flow control functions into a single structural element. This reduces the total number of parts while ensuring stable assembly and reliable liquid flow control
3Ease of manufacture
If the liquid storage cavity has separate inlet and outlet structures, then liquid flow control is achieved, but the structure becomes more complex and processing difficulty increases
Solution Approach 1:
The diversion channels for liquid inlet and outlet are directly formed on the main frame as integrated features, combining multiple flow control functions into a single structural element. This reduces the total number of parts while ensuring stable assembly and reliable liquid flow control
Solution Approach 2:
The main frame serves multiple functions including structural support, containing the liquid storage cavity, and providing integrated diversion channels for liquid flow. This multi-functionality reduces the need for separate components, simplifying both structure and manufacturing

Function Achieved in This Case
The design enhances assembly stability, reduces part complexity, and prolongs the service life of the dispenser while ensuring efficient liquid ejection and pressure management.
Implementation Method 1
when the piston rod moves downward, only the liquid outlet is in an open state, and when the piston rod moves upward, only the liquid inlet is in an open state
