Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing structures in containers, such as bottles and cans, lack accurate control over the amount of liquid dispensed, as the pressing force determines the flow, often resulting in insufficient or excessive liquid, limiting user convenience and practicality.
Innovation Solution
A quantitative pressing structure featuring a piston tube with a piston rod, limiting kits of varying heights, and an elastic member, allowing precise control of liquid flow by adjusting the pressing down degree, with anti-leak features to prevent contamination and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pressing structure is provided to draw liquid out of the container by pressing a pressing head, then the convenience of use is improved, but the amount of liquid flow cannot be accurately controlled according to different requirements
Solution Approach 1:
The pressing structure is segmented into multiple functional components: a pressing head for user operation, a piston rod for force transmission, a piston for liquid displacement, and an outlet for liquid discharge. This segmentation allows independent optimization of each component's function while maintaining overall system coordination.
Solution Approach 2:
The patent introduces intermediary components including a spring mechanism between the pressing head and piston rod to provide elastic feedback, and a flow control valve at the outlet to precisely regulate liquid flow. These intermediaries decouple the direct relationship between pressing force and liquid flow, enabling independent control of each parameter.
2Adaptability or versatility
If different pressing force is exerted on the pressing head to control the pressing head to move down a different trip, then different amount of liquid can be drawn out, but accurate control of liquid flow cannot be achieved
Solution Approach 1:
The patent employs dynamic elements including a spring mechanism that provides progressive resistance during pressing, and a flow control valve with adjustable opening degree. These dynamic components allow the system to adapt to different pressing forces while maintaining precise control over liquid flow rate and total volume dispensed.
Solution Approach 2:
The spring mechanism provides tactile feedback to the user during pressing, indicating the force applied and progress of piston movement. Additionally, the flow control valve can be equipped with indicators showing the current flow rate, creating a feedback loop that enables users to achieve desired liquid amounts with greater precision.
3Quantity of substance
If the pressing head is pressed to the bottom to allow a fixed amount of liquid to flow out, then a certain volume of liquid can be dispensed, but the pressing structure cannot achieve accurate control of liquid flow for different requirements
Solution Approach 1:
The outlet is designed with multi-functionality, serving both as a simple discharge opening for fixed-volume dispensing and as an adjustable flow control valve for variable volume dispensing. The flow control valve can operate in different modes (fully open for maximum flow, partially open for controlled flow, closed for stopping flow), making the single outlet structure capable of fulfilling multiple dispensing requirements.
