Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices with electrically controlled or bionic water tanks suffer from issues such as continuous water dripping, leading to wet rags, floor damage, and water waste due to the inability to adaptively adjust water replenishment.
Innovation Solution
A water tank assembly comprising a main water tank, auxiliary water tank, water pumping device, and water guiding device that allows controlled pumping and discharge of water between storage spaces, preventing excess water accumulation and ensuring adaptive water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bionic water tank uses differential air pressure to output water through a water-absorbent cartridge, then water can be dispensed passively, but water continues dripping when the tank is not in use causing wet rags, floor damage and water waste
Solution Approach 1:
The patent applies dynamics by making the water outlet structure movable rather than fixed. The outlet can dynamically switch between open and closed states based on operational needs, allowing the system to adapt between passive dispensing mode and storage mode, thereby preventing continuous dripping while maintaining ease of operation
Solution Approach 2:
The water guiding device acts as an intermediary between the water storage space and the external environment. It controls water flow through its movable outlet structure, mediating between the need for passive dispensing and the need to prevent unwanted dripping, thus resolving the harmful effect
2Quantity of substance
If an electrically controlled water tank uses software to control water pump replenishment, then quantitative water replenishment can be controlled, but the system cannot adaptively adjust the replenished water amount
Solution Approach 1:
The system dynamically adjusts water replenishment by controlling the opening and closing of the water outlet structure based on real-time operational conditions. This allows the tank to adaptively adjust water amounts without complex software control, achieving both quantitative control and adaptability
Solution Approach 2:
The water tank assembly performs self-service by automatically controlling water outlet based on its own operational state. The system self-regulates water replenishment and dispensing without external software intervention, achieving adaptive adjustment through its own structural mechanisms

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents wet surroundings and water waste by controlling water distribution, maintaining dry conditions and optimizing water usage, thereby avoiding odor, mildew, and floor damage.
Implementation Method 1
The bionic water tank outputs water through a water-absorbent cartridge by using the principle of differential air pressures between the inside and the outside

AI summary
A water tank assembly includes a main water tank and an auxiliary water tank. A water pumping device in operation pumps and discharges water in a first water storage space of the main water tank into a second water storage space of the auxiliary water tank. A water guiding device in operation outputs water from the second water storage space to a preset position. The water pumping device in operation can supply water to the auxiliary water tank as needed. The main water tank does not discharge water into the auxiliary water tank when the water pumping device is not in operation. As a result, the water amount in the auxiliary water tank no longer increases.
