Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with multiple spray nozzles face issues of non-uniform laundry wetting, complex structure, interference with other components, leakage, and abrasion due to the complexity of connecting the circulation pump and nozzles, and gasket deformation during drum rotation.
Innovation Solution
A washing machine design featuring a gasket with multiple nozzles on its inner surface and a distribution pipe that connects the pump to these nozzles, with a unique accommodating part and rib structure to prevent interference and abrasion, allowing for uniform water distribution and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple spray nozzles are connected to the circulation pump through connectors and spray paths, then water can be sprayed into the drum, but the structure becomes complex and assembly becomes bothersome
Solution Approach 1:
The patent integrates multiple spray nozzles directly onto the circulation pump body, merging what were previously separate components (pump and nozzles) into a single integrated unit. This eliminates the need for separate connectors and spray paths, significantly simplifying the overall structure while maintaining the ability to spray water into the drum through multiple nozzles.
Solution Approach 2:
The circulation pump is designed to serve multiple functions: it both pumps water and houses multiple spray nozzles for distributed water delivery. This multi-functional design eliminates the need for separate spray path components, reducing structural complexity while achieving versatile spray coverage.
2Ease of operation
If spray nozzles are connected by passing connectors through the gasket, then water can be distributed to nozzles, but the gasket may deform during drum rotation causing pipe separation
Solution Approach 1:
By integrating the nozzles directly into the pump body, the patent eliminates the gasket penetration connection method entirely. The nozzles are permanently attached to the pump through integrated mounting structures, ensuring stable connections that are not susceptible to gasket deformation during drum rotation.
3Productivity
If the circulation water supply pipe runs near the gasket to reach the nozzles, then water can be supplied to nozzles, but the pipe may be separated due to gasket deformation from vibration
Solution Approach 1:
The patent integrates the water supply function directly into the pump body where the nozzles are located. Water is pumped and delivered to nozzles through internal passages within the integrated pump-nozzle assembly, eliminating the need for external supply pipes that would be vulnerable to separation from gasket deformation.
4Volume of moving object
If the pipe for guiding circulating water runs close to the gasket, then space is saved, but abrasion of the gasket occurs due to friction
Solution Approach 1:
By integrating the nozzles and water delivery system directly into the pump body, the patent eliminates the need for separate pipes running near the gasket. Water circulation occurs through internal passages within the integrated assembly, removing the source of friction-induced gasket abrasion while maintaining compact dimensions.
