Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the washing tank is rotated to sense laundry properties using traditional methods, then measurement accuracy may be improved, but time consumption and power consumption increase
Solution Approach 1:
The patent replaces the mechanical rotation of the washing tank with a millimeter wave sensing system that can detect laundry properties through electromagnetic waves. The sensing unit transmits millimeter waves through the laundry and analyzes the reflected or transmitted waves to determine fabric type, moisture content, and other properties without requiring physical movement of the washing tank, thereby eliminating time loss and additional power consumption associated with rotation.
Solution Approach 2:
The patent introduces millimeter waves as an intermediary medium to sense laundry properties. Instead of directly contacting or mechanically interacting with the laundry, the system uses millimeter waves as a non-contact intermediary to carry information about the laundry's physical and chemical properties to the sensing unit, enabling accurate detection without mechanical intervention.
2Measurement precision
If the washing tank is rotated to sense laundry properties, then comprehensive property analysis may be improved, but power consumption increases
Solution Approach 1:
The patent replaces the mechanical rotation system with a stationary millimeter wave sensing system. The sensing unit remains fixed while transmitting and receiving millimeter waves through the laundry, eliminating the power consumption associated with rotating the washing tank during the sensing process.
Solution Approach 2:
The millimeter wave sensing system enables the laundry to effectively 'present' its own properties to the sensing unit through the interaction of millimeter waves with the fabric materials. The laundry's physical and chemical properties naturally affect the millimeter wave transmission and reflection characteristics, allowing the system to extract comprehensive property information without active mechanical manipulation.
3Device complexity
If washing operations are set based only on laundry amount, then device complexity is reduced, but washing performance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the sensing unit continuously monitors laundry properties (fabric type, moisture content, density) and provides real-time information to the control unit. The control unit adjusts washing parameters such as water level, washing intensity, cycle duration, and temperature based on this feedback, ensuring optimal washing performance adapted to the specific characteristics of the loaded laundry.
Solution Approach 2:
The system performs preliminary sensing of laundry properties before the washing cycle begins and during intermediate stages. Based on this advance information, the control unit pre-adjusts washing parameters to match the detected laundry characteristics, ensuring that the washing process is optimized from the start rather than relying on generic settings based solely on quantity.
