Telescopic Liquid Container with Elastic Bag Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid containers with flexible bags inside a rigid box face challenges in collapsing without forming wrinkles, which can lead to ink remnants being retained, and lack visibility of the emptying process.
Innovation Solution
A liquid container design featuring telescopically movable box parts with an elastic member that expands to stretch the bag into a flat state when emptied, allowing for easy storage and visibility of the emptying progress, with optional scale indicators on the moving part for liquid quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the box is made rigid and regular-shaped to facilitate handling and storage, then handling and storage are improved, but the bag cannot collapse flat and wrinkles form when emptied
Solution Approach 1:
The box is divided into two telescopically movable parts that can slide relative to each other. The first part contains the flexible bag while the second part can be moved to stretch the bag flat, allowing the bag to collapse without wrinkles while maintaining a rigid box structure for handling and storage.
2Volume of moving object
If the box is made compact to reduce storage space, then storage space is improved, but the bag cannot be stretched flat when emptied
Solution Approach 1:
The box incorporates telescopically movable parts that can dynamically change their relative position. When the bag is full, the parts are in a compact retracted state for minimal storage space. When the bag is emptied, the elastic member causes the parts to move apart, stretching the bag flat for easy collapse.
3Device complexity
If the box structure is simplified to reduce complexity, then manufacturing is improved, but visibility of emptying progress cannot be provided
Solution Approach 1:
A scale indicator is provided on the movable part of the box that shows the relative position of the telescopically movable parts. This visual feedback indicates the quantity of liquid remaining in the bag, making the emptying progress visible without adding complex mechanical structures.
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
Enables the container to collapse flat without wrinkles, optimizing storage space and providing visible indication of the emptying process, while maintaining a compact form during transport and storage.
Implementation Method 1
an elastic member is provided for urging the two parts of the box apart

AI summary
A liquid container includes a box and a flexible bag accommodated in the box. The flexible bag contains a liquid and has a first end fixed at the box and a second end opposite to the first end and biased in a direction away from the first end by an elastic member. The box has two parts that are telescopically movable relative to one another and are biased apart by the elastic member. The bag is held at one of these parts with its first end and at the other of these parts with its second end.
