Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Components of dishwashers are prone to separation due to high pumping pressure, requiring separate processes or components like clamps to prevent separation.
Innovation Solution
A dishwasher design featuring a guide member connected to a distribution chamber with a support that includes a holder and coupler, allowing easy mounting and coupling without additional parts, using materials like silicon or ethylene propylene diene monomer (EPDM) to reduce pressure loss and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components like clamps or insert injection processes are used to prevent separation, then connection reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The connector integrates multiple functions into a single component: the connection body guides wash water flow, while integrated locking protrusions and sealing structures prevent separation and leakage. This merging eliminates the need for separate clamps or injection processes, reducing device complexity while maintaining connection reliability under high pumping pressure
Solution Approach 2:
The connector employs self-locking features where protrusions on the connection body automatically engage with corresponding structures on the distribution chamber, creating a self-sustaining connection that resists high pumping pressure without requiring external clamps or additional fastening components
2Stability of the object's composition
If separate components like clamps are used to prevent separation, then connection stability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The connector combines the connection body, locking mechanism, and sealing elements into a single integrated component that can be manufactured as one piece using injection molding. This eliminates the need for separate clamps or multi-step assembly processes, improving ease of manufacture while maintaining connection stability against high pumping pressure
Solution Approach 2:
The integrated connector design allows the component to self-secure through its own structural features (protrusions and recesses), eliminating the need for separate fastening operations or additional components during assembly, thereby simplifying the manufacturing process while ensuring stable connections
3Reliability
If additional components are added to prevent separation, then connection reliability is improved, but device compactness deteriorates
Solution Approach 1:
The connector integrates the connection body, locking protrusions, and sealing structures into a single compact component that attaches directly to the distribution chamber. This merging eliminates the need for separate clamps or additional fastening hardware, maintaining connection reliability under high pressure while preserving device compactness by avoiding extra components that would increase volume

AI summary
Disclosed herein is a dishwasher. The dishwasher includes a washing chamber, a spray unit configured to spray wash water into the washing chamber, a distribution chamber including a lower port through which wash water flows in and out, a distribution cover configured to cover the distribution chamber and including an upper port connected to the spray unit to supply the wash water in the distribution chamber to the spray unit, a guide member connected to the lower port of the distribution chamber so as to guide wash water, and a support detachably coupled to a lower side of the distribution chamber. The support includes a holder formed in a hollow shape and configured to hold one side of the guide member, and a coupler formed on the holder to fix the guide member so as to allow the guide member to correspond to the lower port through the holder.
