Washing Machine Removable Basket Detection Using Inductive Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing machines with removable baskets require manual user input to determine if the basket is in use, leading to potential misuse and increased operational complexity, especially since the use or non-use of the removable basket alters the machine's functional dynamics, necessitating distinct filling and draining steps.
Innovation Solution
A detection system comprising a sensor and a component that causes excitation, strategically placed within the washing machine and on the removable basket, to automatically verify the presence of the basket, using inductive or magnetic interactions to generate a signal indicative of the basket's coupling, allowing the machine to adjust its operation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual user input is required to determine basket usage, then the system maintains simplicity in detection mechanisms, but the operational complexity increases and potential for misuse rises
Solution Approach 1:
The detection system enables the washing machine to automatically determine whether the removable basket is installed by using sensors that detect the presence or absence of the basket without requiring manual user input. The system self-verify basket usage status and automatically adjusts operational parameters accordingly
Solution Approach 2:
The patent replaces manual mechanical verification with electronic sensing mechanisms. Sensors detect the basket's presence through electrical or magnetic fields, substituting the need for mechanical switches or manual user input, thereby reducing operational complexity while maintaining detection simplicity
2Ease of operation
If automatic detection system with sensor and excitation component is implemented, then operational complexity is reduced and misuse is prevented, but device complexity and manufacturing costs increase
Solution Approach 1:
The excitation component serves multiple functions: it generates the electromagnetic field for sensor operation, provides a reference signal for detection, and can potentially serve as part of the motor drive system. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity
Solution Approach 2:
The patent uses an electromagnetic field as an intermediary between the excitation component and the sensor. This field-mediated interaction allows indirect detection of the basket's presence without requiring direct mechanical or electrical contact, simplifying the overall detection system architecture while maintaining automatic verification capability
3Adaptability or versatility
If the removable basket is used, then the washing machine can handle diverse washing needs and improve versatility, but the functional dynamics change requiring distinct filling and draining steps
Solution Approach 1:
The detection system dynamically adjusts the washing machine's operational procedure based on the detected basket configuration. When the removable basket is detected, the system automatically implements a two-stage filling and draining process; when not detected, it uses the standard single-stage process. This dynamic adaptation maintains versatility while managing operational complexity through automation
