Dripping Container Cover With Projections For Viscosity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dripping containers for chemical liquids often result in unintended amounts of liquid being dispensed due to changes in viscosity caused by temperature changes, volatilization, and pressure changes, leading to inconsistent dripping.
Innovation Solution
A dripping container cover with a bottom part and two protruding pressing parts, featuring projections that are strategically positioned to enhance control over the dripping process, allowing for precise alignment and pressure distribution to match user intention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is pressed with force to drip chemical liquid, then the liquid can be dispensed, but the viscosity changes due to temperature and pressure cause unintended amounts to be dispensed
Solution Approach 1:
The patent applies parameter changes by introducing a heat insulating cover that changes the thermal parameter of the container. This prevents temperature-induced viscosity changes in the chemical liquid, thereby maintaining consistent dripping amounts while preserving ease of operation through controlled pressing.
2Reliability
If a heat insulating cover is added to prevent temperature changes, then viscosity stability improves, but the device complexity increases
Solution Approach 1:
The patent employs a heat insulating cover made of thin film or shell material that provides thermal insulation to maintain viscosity stability. This flexible cover adds minimal structural complexity while effectively preventing temperature-induced changes in the chemical liquid's viscosity.
3Manufacturing precision
If the container is designed for precise dripping control, then the dripping amount matches user intention, but the structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the container structure into distinct functional parts: the container body, the heat insulating cover, and the pressing mechanism. This segmentation allows each component to perform its specific function precisely while keeping the overall structure manageable and not overly complex.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cover ensures that chemical liquids are dispensed in the intended amount by controlling the pressure and viscosity, preventing excessive dripping and ensuring consistent dispensing across varying conditions.
Implementation Method 1
