Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machine detergent dispensing methods are inaccurate, leading to insufficient or excessive detergent use, which affects the washing and rinsing efficiency due to variations in clothes weight and material, and limitations in detergent category data storage.
Innovation Solution
A detergent dispensing control method that uses a detergent ingredient detection device and clothes weight detection to identify the detergent category and recommend the optimal dispensing amount, with data stored in the washing machine or cloud for precise dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detergent dispensing is based on rough calculation with limited data storage, then device complexity is reduced, but detergent dispensing precision deteriorates
Solution Approach 1:
The patent introduces an RFID tag as an intermediary carrier that stores detergent category information. This tag acts as a mediator between the detergent and the control system, enabling accurate identification without requiring complex analysis equipment. The control unit reads the RFID tag to obtain detergent category data, which is then used to calculate precise dispensing amounts based on clothes weight and material.
Solution Approach 2:
The patent creates a digital copy of detergent category information stored in the RFID tag. Instead of analyzing the physical detergent composition directly, the system reads the copied information from the tag, which contains pre-stored category data. This copying approach simplifies the detection mechanism while maintaining high precision in detergent identification and dispensing calculation.
2Adaptability or versatility
If detergent category information is stored in RFID tag with limited data size, then device complexity is reduced, but adaptability to all detergent categories deteriorates
Solution Approach 1:
The patent extracts only the essential detergent category information needed for dispensing calculations and stores it in the RFID tag. Instead of storing complete detergent formulations or extensive chemical data, the system extracts and stores only the category classification and corresponding dispensing parameters. This selective extraction enables comprehensive detergent category support within limited storage capacity.
Solution Approach 2:
The patent transforms complex detergent information into simplified parameters that can be stored in limited space. The RFID tag stores condensed category identifiers and associated dispensing coefficients rather than full detergent compositions. The control unit uses these parameter changes to calculate accurate dispensing amounts, achieving high adaptability across different detergent types without requiring large data storage.
3Reliability
If accurate detergent detection and dispensing is implemented, then washing effect is improved, but loss of time in detection and dispensing process increases
Solution Approach 1:
The patent applies preliminary action by pre-storing detergent category information and dispensing parameters in the RFID tag before the washing process begins. The detergent category is identified and the appropriate dispensing parameters are selected in advance, rather than analyzing and calculating during the washing cycle. This preliminary preparation significantly reduces the time required during actual detergent dispensing while ensuring accurate and reliable washing results.

AI summary
The disclosure provides a detergent dispensing control method, a washing machine and a system. The method comprises the following steps of: S1:obtaining a current clothes load through a clothes weight detection device; detecting ingredients of a detergent through a detergent ingredient detection device, and obtaining detergent detection data; S2: analyzing the detergent detection data, and obtaining a detergent category corresponding to the detergent detection data; S3: according to the detergent category and the clothes load, recommending a detergent dispensing amount; and S4: controlling a detergent dispensing device to dispense the detergent by the washing machine. According to the present disclosure, the detergent ingredient detection device is used for identifying the detergent, clothes to be washed are automatically weighed, the most proper detergent dispensing amount is recommended according to an identification result and the clothes load, and the detergent dispensing device is controlled for dispensing the detergent. Therefore, the detergent can be accurately dispensed, the cleaning and rinsing effect of the washing machine on clothes can be improved, and a phenomenon of insufficient or excessive dispensing amount is avoided from occurring.
