Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pressure-type pumping devices for viscous materials, such as creams and shampoos, face challenges in productivity and increased production costs due to complex nozzle structures, making it difficult to efficiently eject and store these materials.
Innovation Solution
A discharge-type cap with a button-activated tube system that allows liquid ejection when pressed and blocks the tube when returned, utilizing an outer housing, button portion, and tube configuration to simplify assembly and reduce production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pressure-type pumping device with a complex nozzle structure is used to eject viscous materials, then the material can be pumped and ejected through a nozzle, but the assembly and production time increases and productivity decreases
Solution Approach 1:
The device is divided into separate functional modules: a container for holding material, a simple nozzle for ejection, and a flexible bladder for pressurization. This segmentation eliminates complex integrated pumping mechanisms while maintaining ejection functionality, thereby reducing assembly complexity and increasing productivity
Solution Approach 2:
The complex pumping function is extracted and replaced by a simpler system combining a flexible bladder and nozzle. The bladder is inserted into the container and pressurized independently, separating the pressurization function from the nozzle structure, which simplifies overall assembly and manufacturing
2Ease of manufacture
If a complex nozzle structure with peripheral components is used, then the material ejection function is achieved, but the production cost increases
Solution Approach 1:
The nozzle is merged with the container opening, eliminating the need for separate complex pumping mechanisms and peripheral components. The flexible bladder is integrated into the container, combining storage and pressurization functions in a single simplified structure, thereby reducing production costs
Solution Approach 2:
The flexible bladder serves multiple functions: it stores material, provides pressurization for ejection, and seals the container. This multi-functionality eliminates the need for separate components, reducing both device complexity and production cost
Applied Scientific Principles
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 solution enables efficient ejection of liquids through a tube when pressed and automatic blocking when the button is returned, simplifying usage and reducing manufacturing costs while maintaining product integrity.
Implementation Method 1
the tube is in a folded closed state when the button portion is in a closed state
Implementation Method 2
when a button portion is pressed and the container is pressurized, a liquid in a container is ejected to the outside through a tube

AI summary
A discharge-type cap includes an outer housing detachably coupled to an inner surface of an upper opening of a container, a button portion hinged to an upper portion of the outer housing, and a tube having one end located in a lower portion of the outer housing and the other end located on a side of the button portion. The button portion includes an upper tube insertion hole which has a lower surface and a side surface communicating to each other and into which the tube is inserted, and the outer housing includes a lower tube insertion hole having a central portion into which the tube is inserted and inclined in a direction in which the other end of the tube is located.
