Dishwasher Cleaning Agent Box With Piston-Aligned Detergent Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher technologies are limited in their ability to use detergents in powder or tablet form, as many automatic dosing systems are designed only for liquid detergents.
Innovation Solution
A dishwasher design that includes a cleaning agent box with a dispenser mechanism, where a piston and cylinder system aligns holes on the dispenser and carrier to release the cleaning agent into the washing tub, allowing for the use of liquid, tablet, or powder detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an automatic dosing unit is designed for liquid detergents only, then the dosing mechanism can be simplified and sealed, but it cannot accept powder or tablet detergent forms
Solution Approach 1:
The dispenser is designed with a universal opening mechanism that can handle multiple detergent forms (liquid, powder, tablet) through a single interface. The piston-driven dispenser with aligned holes creates a universal dispensing action that works regardless of detergent form, eliminating the need for separate dosing mechanisms for each detergent type.
Solution Approach 2:
The dosing mechanism is segmented into distinct functional components: the piston for movement, the dispenser with holes for controlled release, and the carrier for holding different detergent forms. This segmentation allows each component to be optimized for its specific function while maintaining overall compatibility with multiple detergent types.
2Ease of operation
If cleaning agents are stored in a closed box, then the detergent is protected from contamination and premature release, but it cannot be easily accessed or refilled
Solution Approach 1:
The carrier is pre-loaded with cleaning agents in various forms before being inserted into the cleaning agent box. The user performs the loading action in advance during refilling, and the predetermined hole alignment mechanism ensures proper positioning without requiring complex real-time adjustments during operation.
3Productivity
If the dispenser holes are always aligned with carrier holes, then cleaning agent can be easily dispensed, but the cleaning agent cannot be securely stored and transported
Solution Approach 1:
The system dynamically transitions between two states: aligned holes for dispensing and misaligned holes for storage. The piston mechanism provides dynamic control, moving the dispenser to align holes during the dosing phase and misalign them during storage and transport phases, ensuring both secure containment and efficient dispensing at appropriate times.
Solution Approach 2:
The hole alignment occurs periodically during the washing cycle when dosing is required, rather than being continuously aligned. The piston-driven mechanism creates periodic alignment moments synchronized with the washing program, maintaining security during non-dosing periods while enabling rapid dispensing when needed.

Function Achieved in This Case
This design provides flexibility and ease of use by enabling the use of various detergent forms, including powder and tablet detergents, in dishwashers with automatic dosing systems, ensuring proper dosing and integration into the washing process.
Implementation Method 1
the water passing into the cylinder with the pressure of the water flowing in the water line hits the piston and pushes the piston forward
