Dishwasher and base component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overflow structure of dishwashers is prone to clogging due to pollutants entering the overflow channel, making it difficult to detect and clean these pollutants in a timely manner, leading to unpleasant odors.
Innovation Solution
A base component with an overflow cover and water inlet plate featuring filter holes, which forms an overflow chamber to prevent pollutants from entering the channel and allows for easy visual inspection and removal of attached pollutants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pollutants enter the overflow channel directly, then the overflow function is maintained, but the overflow channel becomes clogged easily
Solution Approach 1:
A water inlet plate with filter holes is introduced as an intermediary component between the overflow port and the overflow channel. This filter structure allows water to pass through while blocking pollutants, thus maintaining the overflow function while preventing clogging of the channel
Solution Approach 2:
The harmful function of the overflow port (allowing pollutants to enter) is separated from the useful function (allowing water to overflow). The water inlet plate extracts and blocks pollutants while permitting water flow, thus taking out the harmful aspect while preserving the beneficial overflow capability
2Stability of the object's composition
If the overflow cover is not removed, then the structure remains intact, but it is impossible to visually detect pollutants on the inlet surface
Solution Approach 1:
The water inlet plate is designed with a transparent or translucent portion that allows visual inspection of the inlet surface for pollutants. This enables detection of pollution without removing the overflow cover, maintaining structural integrity while enabling monitoring
Solution Approach 2:
The transparent water inlet plate acts as an intermediary that allows optical penetration from the exterior to the inlet surface. This mediator enables visual detection of pollutants while the overflow cover remains in place, solving both the structural integrity and detection requirements
3Reliability
If pollutants are not cleaned in time, then the overflow channel functions normally, but unpleasant odors occur
Solution Approach 1:
The transparent water inlet plate provides visual feedback about the accumulation of pollutants on the inlet surface. Users can observe pollutant buildup through the transparent portion and clean the filter promptly, preventing odor generation while maintaining overflow channel functionality
Solution Approach 2:
The transparent design enables preliminary detection of pollutants before they decompose and generate odors. Users can perform maintenance cleaning in advance based on visual inspection, preventing the harmful odor effect before it occurs
