Solution Overview
Problem
Existing robot cleaners for wet cleaning face challenges in uniformly supplying liquid to multiple cleaners due to complex and differently sized hose configurations, making it difficult to inspect and repair defects such as water leakage.
Innovation Solution
A robot cleaner design featuring a main body with cleaner fixing portions at the lower part, a liquid supply portion, a detachable liquid distribution member with nozzles at the lower part, and a flow path portion that simplifies liquid distribution and facilitates easy inspection and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hose formed of flexible material is used for liquid supply, then the robot cleaner can be assembled with flexible connections, but it becomes difficult to uniformly supply water to multiple cleaners due to different hose lengths
Solution Approach 1:
The liquid distribution member is divided into multiple units, each having a nozzle, and is configured to directly supply liquid to corresponding cleaners without using flexible hoses. This segmentation eliminates the need for length-adjustment of hoses while maintaining flexible positioning capability through the modular structure.
2Adaptability or versatility
If a complicated hose structure is used for liquid supply, then the robot cleaner can accommodate various cleaner positions, but it becomes difficult to inspect and repair defects such as water leakage
Solution Approach 1:
The liquid distribution member is designed to be detachably coupled to the lower portion of the main body, allowing it to be easily removed as a complete unit. This extraction approach eliminates the need to disassemble complex hose connections for inspection or repair, as the entire distribution system can be accessed by simply detaching one component.
3Adaptability or versatility
If multiple hoses of different lengths are provided, then the robot cleaner can reach various cleaner positions, but the device complexity increases
Solution Approach 1:
Multiple liquid supply functions are merged into a single liquid distribution member that directly contacts multiple cleaners simultaneously. This consolidation eliminates the need for multiple separate hoses of different lengths, reducing structural complexity while maintaining the ability to supply liquid to various cleaner positions through the integrated distribution member.
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 design allows for easy detachment and inspection of the liquid distribution member, reduces manufacturing costs, ensures uniform liquid supply to multiple cleaners, and allows for easy identification of water leakage without liquid entering the cleaner's interior.
Implementation Method 1
a liquid distribution member provided at a lower portion of the main body portion and directly supplying the stored liquid to at least one cleaner of the plurality of cleaners
