Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers often fail to completely remove residues such as starch, protein, and lime deposits during standard cleaning, leading to cumulative build-ups that require labor-intensive manual basic cleaning.
Innovation Solution
A programmable dishwasher that automatically adjusts treatment parameters for both the cleaning and rinsing phases based on whether standard or basic cleaning is required, optimizing parameters like temperature, contact time, nozzle pressure, and rinsing fluid quantity to prevent overtreatment and achieve effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If standard cleaning parameters are used in conventional dishwashers, then the cleaning process is simple and quick, but residues such as starch, protein, and lime deposits are not completely removed, leading to cumulative build-ups
Solution Approach 1:
The patent implements dynamic adjustment of cleaning parameters (temperature, contact time, nozzle pressure, rinsing fluid quantity) based on the selected cleaning mode. The system transitions from static standard parameters to dynamic adaptive parameters that optimize cleaning effectiveness for different soiling levels while managing process complexity through automated control.
Solution Approach 2:
The invention changes multiple cleaning parameters simultaneously when basic cleaning mode is selected: increasing temperature, extending contact time, adjusting nozzle pressure, and modifying rinsing fluid quantity. This multi-parameter approach resolves the contradiction by achieving superior cleaning effectiveness without requiring complex manual intervention, as the changes are automated.
2Manufacturing precision
If manual basic cleaning is performed to remove cumulative residues, then cleaning effectiveness is improved, but labor time and costs increase
Solution Approach 1:
The dishwasher system performs self-service by automatically executing basic cleaning programs when residues are detected or when selected by the user. The automated system adjusts parameters and executes the cleaning cycle without human intervention, eliminating the need for manual basic cleaning while maintaining high residue removal effectiveness.
Solution Approach 2:
The system incorporates feedback mechanisms through program control that monitors cleaning conditions and automatically adjusts parameters. When basic cleaning is required, the control system detects this need and automatically implements the appropriate parameter adjustments, creating a closed-loop system that eliminates manual intervention and reduces cleaning time.
3Manufacturing precision
If treatment parameters are increased to remove stubborn residues, then cleaning effectiveness is improved, but risk of overtreatment and resource consumption increases
Solution Approach 1:
The patent applies partial excessive action by increasing treatment parameters (temperature, contact time, nozzle pressure) only when basic cleaning mode is selected and stubborn residues are present. The system avoids excessive action in standard cleaning scenarios, thereby removing stubborn residues effectively while minimizing unnecessary resource consumption through mode-based parameter selection.
Solution Approach 2:
The invention implements local quality by applying different parameter sets to different cleaning needs. The system selectively increases temperature, contact time, and fluid quantity only for basic cleaning operations targeting stubborn residues, while maintaining standard parameters for routine cleaning. This localized parameter adjustment achieves effective residue removal without universal over-treatment and associated resource waste.

Implementation Method 1
a cleaning system with a pump, with a line system connected to the pump and with cleaning nozzles. The fluid (cleaning fluid or detergent solution) contained in the tank arranged beneath the treatment chamber can be conveyed to the cleaning nozzles by the pump via the line system
Implementation Method 2
beneath the treatment chamber, a tank is arranged, in which fluid sprayed in the treatment chamber can flow back by gravity
