Dishwasher Bottle Rack Accessory for Narrow-Opening Bottle Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hollow articles with narrow openings, such as drinking and feeding bottles, often fail to receive sufficient washing/rinsing liquid in domestic dishwashers, leading to poor cleaning results and user dissatisfaction.
Innovation Solution
An article rack accessory with an ascending pipe that penetrates into hollow articles and diverts upwardly sprayed washing/rinsing liquid from the dishwasher nozzles into the articles, ensuring thorough cleaning without additional hydraulic connections, reducing parts and costs, and improving energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hollow articles with narrow openings are placed in a standard dishwasher rack, then the dishwasher structure remains simple, but the articles do not receive sufficient washing liquid and cleaning performance deteriorates
Solution Approach 1:
The washing system is segmented into standard spray coverage and targeted internal flushing. The ascending pipe accessory segments the washing function by providing dedicated internal article flushing while the main spray arms handle external surfaces, resolving the contradiction between simple structure and effective cleaning of narrow-opening articles
Solution Approach 2:
The ascending pipe acts as an intermediary device that bridges the gap between the spray nozzle and the interior of hollow articles. It captures sprayed liquid and delivers it internally, serving as a mediator that enables effective cleaning without requiring complete redesign of the dishwasher structure
2Manufacturing precision
If additional hydraulic lines are added to deliver washing liquid into hollow articles, then cleaning performance improves, but device complexity and cost increase
Solution Approach 1:
The ascending pipe system is self-service in that it passively captures washing liquid already being sprayed by the main nozzles and redirects it into hollow articles. No additional hydraulic lines, pumps, or water delivery systems are needed - the system uses the existing spray infrastructure to serve the additional function of internal article flushing
Solution Approach 2:
The ascending pipe serves multiple functions: it acts as a support structure for the hollow article, captures washing liquid from the spray nozzle, and delivers it internally. This multi-functionality eliminates the need for separate hydraulic lines while maintaining improved cleaning performance
3Manufacturing precision
If the washing liquid is diverted through additional components, then internal cleaning improves, but energy efficiency decreases
Solution Approach 1:
The ascending pipe maintains continuous useful action by capturing washing liquid directly from the spray nozzle and immediately delivering it into the hollow article. This continuous flow path minimizes energy loss and ensures that the kinetic energy of the sprayed liquid is effectively utilized for internal cleaning without interruption or additional energy-consuming components
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
The ascending pipe ensures intensive washing and rinsing of hollow articles, reducing the risk of poor cleaning results, enhancing hygiene, and improving customer satisfaction by directly utilizing existing nozzle-sprayed liquid, while minimizing parts and costs.
