Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual parameter setting is used for water softener, then device complexity is reduced, but ease of operation deteriorates due to inconvenient control
Solution Approach 1:
The water softener automatically detects user presence through image recognition and autonomously adjusts water hardness parameters based on the detected user's profile, eliminating the need for manual operation while maintaining simple device architecture
Solution Approach 2:
The patent replaces manual mechanical control with automated image recognition and processing systems to detect user features and determine appropriate water softening parameters, improving ease of operation through non-contact automation
2Measurement precision
If manual parameter setting is used for water softener, then device complexity is reduced, but measurement precision deteriorates due to inaccurate settings for different users
Solution Approach 1:
The patent employs image recognition technology to automatically detect and analyze user features such as face characteristics, replacing manual identification methods and enabling accurate user-specific parameter adjustment without increasing physical device complexity
Solution Approach 2:
The system creates digital profiles of users based on image recognition data, storing user features and preferred water hardness settings as digital copies that enable consistent and accurate parameter adjustment for each user without requiring complex real-time analysis
3Ease of operation
If automatic control based on user features is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The control system is designed to perform multiple functions including user detection, feature recognition, parameter determination, and appliance control within a single integrated module, reducing overall device complexity while enabling automatic control based on user features
Solution Approach 2:
The patent introduces an image processing module as an intermediary between the user and the water softener control system, translating visual user features into control parameters without requiring direct user interaction or complex control logic in the main system

AI summary
Provided are a control method, a control apparatus and a control device for a household appliance. The control method for a household appliance includes obtaining a user feature of a target user (S201); determining a hardness of bathing water for the target user based on the user feature of the target user (S202); and generating a control instruction for a water softener based on the hardness of the bathing water (S203). The control method realizes automatic control over a water softener, improves the convenience of controlling the water softener, and determines the hardness of bathing water in combination with user features, thereby improving the accuracy of hardness determination, and improving the bathing experience of a user.
