Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select programs based on soil levels and load conditions, then the user interface provides basic functionality, but the cleaning result and user-friendliness are suboptimal
Solution Approach 1:
The acceleration sensor automatically detects loading actions and triggers program selection without user intervention. The system serves itself by monitoring its own state changes (door opening, loading vibrations, door closing) and autonomously determining the appropriate wash program, eliminating the need for manual user input while improving convenience
Solution Approach 2:
The patent replaces manual mechanical interaction (user pressing buttons or selecting programs) with automated sensor-based detection. The acceleration sensor captures mechanical vibrations and movements during loading, and the control unit processes this data to automatically select programs, substituting the mechanical user interface interaction with an automated sensing and control system
2Manufacturing precision
If device parameters are automatically adjusted based on load conditions, then the cleaning result improves, but the system requires active user selection of programs
Solution Approach 1:
The acceleration sensor continuously monitors the treatment chamber for vibrations and movements indicative of loading actions. This feedback loop allows the control unit to detect when objects are placed in the dishwasher, determine the load type and amount, and automatically adjust program parameters accordingly, achieving both improved cleaning results and eliminated user intervention
Solution Approach 2:
The system automatically detects loading conditions through acceleration sensors and self-adjusts program parameters without requiring user input. The control unit processes sensor data to identify load characteristics and autonomously selects optimal wash programs, making the system self-sufficient in determining appropriate cleaning parameters
3Extent of automation
If acceleration sensors are used to detect loading actions, then automatic program selection is achieved, but the device complexity increases
Solution Approach 1:
The acceleration sensor acts as an intermediary between the physical loading action and the control system. It converts mechanical vibrations and movements into electrical signals that the control unit can process, serving as a bridge that enables automatic detection without requiring complex direct sensing mechanisms throughout the entire system
Solution Approach 2:
The system detects changes in acceleration parameters (vibration patterns, movement intensity, duration) to identify different loading scenarios. By monitoring parameter changes in the acceleration data rather than requiring complex sensor arrays, the system achieves automatic program selection through analysis of dynamic parameter variations during the loading process
