Nested Liquid Tank Design for Base Station Volume Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base stations equipped with two liquid storage tanks for cleaning and sewage occupy a large volume and have high construction costs.
Innovation Solution
An integrated liquid tank system with a flexible, variable second storage structure nested in a first storage structure, featuring an anti-sticking structure on the first storage structure's bottom surface to prevent adhesion and facilitate separation, allowing for alternating liquid storage without the need for two separate tanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate liquid storage tanks are used for cleaning liquid and sewage, then the base station can store different liquids separately, but the base station occupies a large volume and has high construction cost
Solution Approach 1:
The patent applies nesting by placing the second liquid storage tank inside the first liquid storage structure. The first tank stores cleaning liquid while the second tank stores sewage, allowing both liquids to be stored separately within a compact integrated structure, thereby reducing the overall base station volume while maintaining liquid separation functionality
Solution Approach 2:
The patent merges two separate liquid storage tanks into a single integrated structure where the second tank is nested within the first. This combination reduces the total volume occupied by the base station while still enabling separate storage and management of cleaning liquid and sewage through the anti-sticking structure
2Productivity
If the second liquid storage structure is made flexible and variable in volume, then the integrated tank can alternate storage efficiently, but the bottom wall sticks to the bottom wall of the external tank when full, making separation difficult
Solution Approach 1:
The patent applies preliminary anti-action by equipping the first liquid storage structure with an anti-sticking structure before the second tank can adhere to it. This anti-sticking structure prevents the bottom wall of the flexible second tank from sticking to the first tank when full, thereby maintaining ease of separation while preserving the volume efficiency benefits of the flexible design

AI summary
A liquid tank for a base station includes a first liquid storage structure and a second liquid storage structure. The second liquid storage structure is positioned in the first liquid storage structure. The second liquid storage structure is flexible and variable in volume. A space is defined between a structural wall of the first liquid storage structure and a structural wall of the second liquid storage structure and is configured to store liquid. The first liquid storage structure includes an anti-sticking structure. The anti-sticking structure is positioned on a bottom surface of the first liquid storage structure facing the second liquid storage structure.
