Pivoting Dishwasher Sprayer for Tall and Wide Kitchenware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dishwashers often fail to effectively clean tall, narrow kitchenware items like bottles and glasses due to inadequate water contact, and existing placement apparatuses occupy additional space and hinder basket utilization when not in use.
Innovation Solution
A dishwasher design featuring a spraying member that can pivot between vertical and horizontal positions, allowing for adjustable water distribution to accommodate different kitchenware shapes, with a conduit system enabling water transmission and a blocking mechanism to maintain high pressure when in horizontal position for wider items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If placement apparatuses are used to clean tall narrow kitchenware, then washing efficiency is improved, but the available volume of the basket is decreased
Solution Approach 1:
The spraying member is designed to perform multiple functions: it can be positioned vertically to clean tall narrow items like bottles and glasses, and horizontally to clean wide flat items like trays and plates. This multi-functionality eliminates the need for separate placement apparatuses, maintaining basket volume while achieving effective cleaning of various kitchenware types.
Solution Approach 2:
The spraying member is made movable and adjustable, allowing users to change its position between vertical and horizontal orientations. This dynamic capability enables a single device to adapt to different cleaning needs, replacing static placement apparatuses and maximizing basket utilization.
2Productivity
If spraying member is positioned vertically to clean tall narrow items, then washing of bottles and glasses is improved, but washing of wide flat items becomes difficult
Solution Approach 1:
The spraying member can be freely adjusted between vertical and horizontal positions, allowing it to adapt to different kitchenware shapes. When vertical, it effectively cleans tall narrow items; when horizontal, it reaches wide flat surfaces, providing versatile washing capability for various item types.
Solution Approach 2:
A single spraying member design performs both vertical and horizontal cleaning functions, making it universally applicable to different kitchenware geometries without requiring separate specialized devices for tall narrow items and wide flat items.
3Area of stationary object
If multiple orifices are kept open for horizontal spraying, then water coverage area is increased, but water pressure decreases
Solution Approach 1:
The blocking member provides selective control over orifice openings based on the spraying direction. When spraying horizontally, only certain orifices remain open while others are blocked, concentrating water flow to maintain pressure. This local quality control allows the system to optimize between coverage area and pressure depending on the specific cleaning need.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances washing efficiency by ensuring thorough cleaning of elongated and wide kitchenware with adjustable spraying member positions and high-pressure water distribution, facilitating convenient placement and easy cleaning of the conduit.
Implementation Method 1
A plurality of orifices are provided on the spraying member. Water received through the conduit is thus transmitted on kitchenware by means of the spraying member
Implementation Method 2
When the spraying member is in horizontal position, the orifices facing the blocking member are covered by means of the plugs. This enables the orifices kept open to transmit water with a higher pressure.
