Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the drying time is preset in the existing clothing care machine, then the machine can operate automatically, but it cannot automatically judge whether the clothes have been dried, leading to poor drying effect and increased energy consumption
Solution Approach 1:
The patent implements a feedback mechanism by installing humidity sensors inside the drying chamber to continuously detect the humidity of clothes during the drying process. The controller receives real-time humidity data and automatically adjusts the drying operation, comparing current humidity levels with initial values to determine when drying is complete. This closed-loop feedback system resolves the contradiction by enabling accurate automatic detection without requiring complex manual intervention.
Solution Approach 2:
The drying system performs self-service by automatically monitoring its own drying process through integrated humidity sensors and controllers. The system independently determines drying completion based on humidity changes detected during operation, eliminating the need for external judgment or preset fixed-time controls. This self-monitoring capability improves detection accuracy while maintaining system simplicity.
2Productivity
If the preset drying time is used regardless of the amount or degree of wetness of clothes, then the operation is simple, but the drying effect is poor and energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the drying time adaptive rather than fixed. The controller dynamically adjusts the drying process duration based on real-time humidity detection from sensors placed inside the drying chamber. The system continuously monitors humidity changes and automatically extends or shortens the drying time according to the actual moisture content of the clothes, thereby improving drying efficiency while avoiding unnecessary energy consumption from prolonged operation.
Solution Approach 2:
The system changes the operational parameter of drying time based on detected humidity levels. Instead of using a constant preset time, the controller modifies the drying duration parameter in response to real-time humidity data from the sensors. This parameter adaptation allows the system to optimize energy usage by stopping drying exactly when clothes reach the desired dryness level, regardless of the initial amount or wetness degree of the clothes.
3Adaptability or versatility
If the existing clothing care machine cannot automatically judge drying completion, then the control system is simple, but the drying effect varies with different amounts and wetness degrees of clothes
Solution Approach 1:
The patent recovers the lost drying status information by implementing feedback through humidity sensors positioned inside the drying chamber. These sensors continuously provide information about the moisture content of clothes during drying, enabling the controller to adaptively adjust the drying process. This feedback mechanism allows the system to handle various clothes conditions (different amounts and wetness degrees) effectively, improving adaptability while maintaining simple control through automatic humidity-based decision-making.
