Dispensing Container With Gas Channel For Fixed Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common containers lack a mechanism to ensure a fixed or limited quantity of content removal, leading to inconsistent usage and potential excess or waste, particularly in applications like oil, soy sauce, and toothpaste, where precise amounts are advised for daily use.
Innovation Solution
A container design incorporating a pressurizing mechanism, a gas channel, and a moving component that adjusts the outflow to allow for precise control of the quantity removed, using a gas pocket to prevent contamination and facilitate repeatable, fixed-volume removals without excess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a container allows free removal of contents, then ease of operation is improved, but quantity control deteriorates
Solution Approach 1:
The gas channel opening is made movable rather than fixed, allowing it to dynamically adjust its position along the movement track. This enables the opening to move between a closed state (preventing removal) and an open state (allowing controlled removal), thereby achieving both ease of operation when needed and precise quantity control through the limited opening size and controlled exposure time
Solution Approach 2:
The opening's exposure parameters (position, size, duration) are changed to control the removal process. By adjusting the opening's position along the movement track and controlling how long it remains exposed, the system precisely limits the quantity of contents removed while maintaining ease of operation through automated control
2Productivity
If excess removal is allowed, then productivity is improved, but loss of substance worsens
Solution Approach 1:
The gas channel opening is deliberately designed to be smaller than the full outflow channel opening, creating a controlled partial opening. This limits the maximum removal rate and total quantity removed, preventing excessive removal and waste while still enabling productive removal at the controlled rate through the limited opening
Solution Approach 2:
The system uses feedback control where the opening's position and exposure duration are monitored and adjusted to ensure precise quantity control. The opening moves along a predetermined track and stops at specific positions, providing automatic feedback control that prevents over-removal and waste while maintaining efficient productivity
3Productivity
If return of contents is allowed, then productivity is improved, but object-affected harmful factors worsen
Solution Approach 1:
The gas channel is extracted as a separate, controlled pathway distinct from the main outflow channel. This allows the gas channel opening to selectively control when and how contents can return, separating the return function from the main flow path and enabling pollution prevention through controlled access
Solution Approach 2:
The gas channel opening acts as an intermediary mechanism between the container interior and exterior. By controlling the opening's position and exposure, it mediates the return process, allowing return only under controlled conditions that prevent pollution while maintaining productivity

AI summary
A container capable of dispensing a quantity of contents less than or equal to a set value. The container includes a main body portion, a pressurizing portion and an outflow channel, wherein the main body portion includes a space for holding the contents and a space for gas, the pressurizing portion increases the gas pressure in the space for gas, and the outflow channel communicates with the space for holding the contents to allow the outflow of the contents; it also includes a moving component in the outflow channel movable with the contents to be taken out, and a gas channel outlet moving with said moving component; on the movement track of the gas channel outlet there is an opening communicating with ambient air and in communication with the gas channel outlet; the other end of the gas channel opens in the space for gas in the main body portion.
