Surface cleaning machine comprising a lid device for a tank device for dirty fluid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning machines are not designed in a simple and compact manner, making them inefficient in supplying cleaning fluid to the cleaning roller units and effectively managing dirty fluid collection.
Innovation Solution
The surface cleaning machine incorporates a dirty fluid tank device with a container and cover device, featuring a channel for cleaning liquid application and a stripping guide for fan-free dirty fluid stripping, ensuring optimized cleaning results with a structurally simple design. The channel device is integrated into the cover device, allowing for easy access and cleaning, and the retaining elements prevent fluid leakage during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the channel device and outlet device are integrated into the cover device, then the surface cleaning machine can be designed in a simple and compact manner, but the complexity of fluid distribution may increase
Solution Approach 1:
The channel device and outlet device are merged into the cover device, which simplifies the overall structure by reducing the number of separate components. The cover device now performs multiple functions: covering the container and providing fluid distribution channels and outlets to the cleaning roller units.
Solution Approach 2:
The cover device is designed with multi-functionality, serving both as a protective cover for the container and as a fluid distribution system. The integrated channel and outlet devices enable the cover to simultaneously manage structural protection and cleaning fluid delivery to the rollers.
2Manufacturing precision
If the outlet device is designed to apply cleaning liquid to the entire trimming length, then optimized cleaning results are achieved, but the device complexity increases
Solution Approach 1:
The outlet device is segmented into multiple outlets arranged along the trimming length, with each outlet serving a specific section. This segmentation allows uniform cleaning coverage across the entire roller length while keeping each individual outlet simple in design.
Solution Approach 2:
The outlet device is designed with local quality by positioning specific outlets at specific locations along the trimming length. Each outlet is optimized for its local region, ensuring that cleaning liquid is applied uniformly across the entire cleaning roller unit length.
3Quantity of substance
If the container device is designed with large capacity, then more dirty fluid can be collected, but the device dimensions increase
Solution Approach 1:
The container device is designed with nesting, where the dirty fluid tank is positioned within or adjacent to the clean water tank structure. This nested arrangement maximizes the dirty fluid capacity within the overall device volume, allowing more storage without proportionally increasing the external dimensions.
