Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water cleaners face issues with limited internal space and insufficient dirt-holding capacity in their filtering mechanisms, leading to clogging and reduced purification performance and efficiency.
Innovation Solution
A water cleaner design featuring a filter mechanism with a support cylinder and filter cartridge, along with an impeller assembly and water-retaining assembly, which effectively directs sewage flow and prevents dirt from entering the filter mechanism, enhancing dirt-holding capacity and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mesh bags or stainless steel filter screens are used as the filtering mechanism, then the structure is simple and easy to manufacture, but the internal space is limited and dirt-holding capacity is insufficient
Solution Approach 1:
The patent applies nesting by placing the filter cartridge inside the support cylinder, creating a nested structure where the filter mechanism is contained within the housing. This nested arrangement maximizes the use of internal space while maintaining structural simplicity, thereby increasing dirt-holding capacity without complicating the manufacturing process.
2Quantity of substance
If the internal space is increased to improve dirt-holding capacity, then the filtering performance is improved, but the device complexity increases
Solution Approach 1:
The patent segments the filtering system into distinct components: the support cylinder and the filter cartridge. This segmentation allows each component to be optimized independently - the support cylinder provides structural framework and space for dirt accumulation, while the filter cartridge performs the actual filtration. This modular segmentation increases dirt-holding capacity while keeping each individual component relatively simple in structure.
3Reliability
If the filter holes are blocked by dirt, then the purification performance is weakened, but increasing the dirt-holding capacity requires more complex structure
Solution Approach 1:
The patent applies preliminary action by designing the support cylinder to provide sufficient dirt-holding capacity before the filter cartridge becomes clogged. The support cylinder's internal space is structured to accumulate dirt particles before they reach the filter holes, preventing clogging in advance. This preliminary capacity planning maintains reliable purification performance without requiring complex anti-clogging mechanisms.

Function Achieved in This Case
The design significantly improves the dirt-holding capacity and filtration efficiency of the water cleaner, ensuring effective purification of sewage by preventing dirt from clogging the filter mechanism and optimizing the use of internal space.
Implementation Method 1
the impeller generates a centrifugal force for sucking the sewage to be treated and the clean water

AI summary
A water cleaner, including a housing and a filter mechanism. Two ends of the housing are provided with a first inlet and a first outlet, respectively. The filter mechanism is arranged in the housing. A first end and/or an outer circumference of the filter mechanism are/is provided with a second inlet, and a second end is provided with a second outlet. The sewage flows into the housing through the first inlet and flows towards the filter mechanism to be filtered. The obtained clean water flows into the filter mechanism through the second inlet and flows out of the housing through the second outlet and the first outlet in sequence. The first end of the filter mechanism is close to the first inlet, and the second end is close to the first outlet.
