Washing system for cleaning items to be cleaned
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing systems in dishwashers often face issues with dirt particles getting stuck in nozzle openings, leading to inadequate cleaning results and complex maintenance processes, including the risk of the cleaning opening remaining open or being lost, which can render the dishwasher inoperable.
Innovation Solution
A washing system with a self-closing cleaning opening mechanism, featuring a resilient closure element that automatically seals the cleaning opening during operation and can be easily opened for maintenance, ensuring efficient rinsing and preventing dirt accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a cleaning opening is provided in the washing system for rinsing dirt particles, then maintenance and cleaning become easier, but the cleaning opening may remain accidentally open or be lost, rendering the dishwasher inoperable
Solution Approach 1:
The closure element is designed to close the cleaning opening automatically without requiring manual intervention. The resilient nature of the closure element allows it to return to the closed position by itself after being opened, ensuring the opening is properly sealed without relying on user memory or attention
Solution Approach 2:
The patent replaces complex mechanical locking mechanisms with a simple resilient closure element that uses elastic deformation to achieve automatic closing. This substitution eliminates the need for intricate latch mechanisms while ensuring reliable closure
2Reliability
If a closure element is used to seal the cleaning opening, then the opening remains sealed during operation, but the closure element may be lost or inadvertently left open
Solution Approach 1:
The closure element automatically returns to the closed position through its resilient properties, eliminating the need for manual closing operations. The system serves itself by using the elastic recovery of the closure element to ensure proper sealing without user intervention
Solution Approach 2:
The closure element transitions between dynamic states (open and closed) based on operational needs. During maintenance, it can be easily opened, and during normal operation, it automatically returns to the closed position, providing dynamic adaptability to different operational phases
3Ease of repair
If the cleaning opening is always accessible, then maintenance is simplified, but dirt particles can enter the interior of the washing system during operation
Solution Approach 1:
The closure element provides automatic protection by closing the cleaning opening without requiring manual operation. The resilient closure element ensures the opening is sealed during normal operation, preventing contamination while requiring no active management from the user
Solution Approach 2:
The closure element acts as an intermediary between the cleaning opening and the interior of the washing system. It provides a physical barrier that prevents dirt particles from entering while allowing controlled access during maintenance operations
