Removable Refrigerator Ice Tray Assembly for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ice-making assemblies in refrigerators have a fixed ice-making tray, making it difficult to clean and maintain, as the tray cannot be easily removed or disassembled for cleaning purposes.
Innovation Solution
The ice-making assembly is designed to allow the ice-making tray to be selectively removed and cleaned by incorporating a gear assembly and lever system that enables the tray to be rotated and withdrawn, allowing for easy access and cleaning without disassembling the entire unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ice-making tray is fixed to the ice-making assembly, then the structural stability is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The ice-making assembly is divided into separable components: the ice-making tray can be independently removed from the assembly, while the water tank and ice bank remain removably coupled. This segmentation allows the tray to be easily extracted for cleaning without affecting the overall structural integrity of the remaining assembly.
Solution Approach 2:
The ice-making tray transitions from a fixed state to a movable state through the introduction of a gear assembly and lever system. The tray can be rotated and withdrawn when cleaning is needed, while maintaining its positioned state during normal operation, thus adapting its fixation status dynamically based on operational requirements.
2Device complexity
If the ice-making tray is fixed in place, then the device complexity is reduced, but the ease of maintenance deteriorates
Solution Approach 1:
The maintenance system is segmented into modular components including the ice-making tray, gear assembly, and lever mechanism. Each component can be independently accessed and maintained, with the tray being the primary removable element for routine cleaning while other components remain in place.
Solution Approach 2:
The ice-making tray is designed to be user-removable and cleanable without requiring professional service or disassembly of the entire assembly. The simple extraction mechanism allows end-users to perform maintenance themselves by merely withdrawing the tray from the assembly.
3Ease of operation
If the ice-making tray is removable, then the ease of cleaning is improved, but the device complexity increases
Solution Approach 1:
The removal mechanism is segmented into simple, discrete components rather than a complex integrated system. The gear assembly and lever are separate elements that work together to enable tray removal, keeping each individual component simple while achieving the overall function of easy tray extraction.
Solution Approach 2:
The complexity of the removal mechanism is localized to specific areas of the assembly rather than being distributed throughout. The gear assembly and lever are confined to particular locations, allowing the majority of the ice-making assembly to remain simple and unchanged in structure.
