Automatic Liquid Detergent Dispensing for Washing Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines require users to manually add liquid detergent for each wash cycle, leading to inconvenience and reduced efficiency.
Innovation Solution
A washing machine design that includes a liquid detergent container and a detergent supply unit, where wash water is injected and mixed with liquid detergent, which is then supplied to the tub, utilizing a liquid detergent supply path and pump to automate the detergent distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually add liquid detergent for each wash cycle, then the washing machine can be operated, but the convenience and efficiency of detergent use is reduced
Solution Approach 1:
The liquid detergent is pre-filled into a container that is installed in the washing machine before use. The system automatically dispenses the required amount of detergent during each wash cycle without requiring user intervention, thereby eliminating the time and inconvenience of manual detergent addition while maintaining proper detergent dosage
Solution Approach 2:
The washing machine is equipped with an automatic detergent dispensing system that independently manages the liquid detergent supply. The system automatically draws detergent from the container and delivers it to the wash drum, enabling the machine to serve itself without human intervention and improving operational convenience
2Extent of automation
If a liquid detergent container and supply path are added to the washing machine, then automated detergent distribution is achieved, but the device complexity increases
Solution Approach 1:
The liquid detergent container is extracted as a separate, removable component from the main washing machine body. This modular design allows the container to be independently filled, removed for refilling, and reinstalled, thereby automating detergent distribution while minimizing the impact on overall device complexity and facilitating easy maintenance
Solution Approach 2:
A supply path acts as an intermediary channel connecting the liquid detergent container to the wash drum. This intermediate structure enables automated detergent delivery through a simple, direct route, achieving automation functionality without requiring complex mechanical or electronic dispensing mechanisms
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
