Solution Overview
Problem
Conventional laundry dryers often leave clothes with wrinkles, requiring additional ironing, and there is a need for a device that can prevent or remove wrinkles effectively after usage.
Innovation Solution
A laundry dryer equipped with a steam generator and a detachable water supply source, where the steam generator's power is controlled based on the water supply status to prevent or remove wrinkles and ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional laundry dryers are used to dry washed laundry, then the drying function is achieved, but wrinkles are not removed and additional ironing is required
Solution Approach 1:
The patent combines the drying function and wrinkle removal function into a single integrated process. The steam generator produces steam that is injected into the drum during the drying cycle, allowing the dryer to simultaneously dry laundry and remove wrinkles without requiring separate ironing operations.
Solution Approach 2:
The patent introduces steam injection as a new parameter change during the drying process. By injecting steam into the drum, the temperature and humidity conditions are modified to enable wrinkle removal while maintaining the drying function, thus improving overall productivity without sacrificing ease of operation.
2Productivity
If a steam generator is added to remove wrinkles, then wrinkle removal capability is improved, but device complexity increases
Solution Approach 1:
The steam generator is designed to serve multiple functions: it produces steam for wrinkle removal and also contributes to the drying process by modifying the thermal environment in the drum. This multi-functionality justifies the added complexity by delivering dual benefits within a single component.
Solution Approach 2:
The patent introduces a control unit as an intermediary that manages the steam generator's operation. The control unit receives signals from a sensor that detects whether a water container is properly installed, and accordingly controls the steam generator's power supply, thereby automating the complexity management and reducing user burden.
3Productivity
If the steam generator operates continuously, then wrinkle removal effectiveness is improved, but energy consumption increases
Solution Approach 1:
The steam generator operates periodically rather than continuously. The control unit regulates the steam generator based on detected conditions (such as water container presence and drying cycle stage), activating it only when needed for wrinkle removal during specific phases of the drying cycle, thus reducing overall energy consumption while maintaining effectiveness.
Solution Approach 2:
The patent implements a feedback mechanism where a sensor detects the water container's presence and communicates this information to the control unit. The control unit uses this feedback to intelligently control the steam generator's operation, ensuring it runs only under appropriate conditions, thereby optimizing energy usage while maintaining wrinkle removal effectiveness.
4Ease of repair
If a detachable water supply source is used, then ease of maintenance is improved, but reliability may be affected
Solution Approach 1:
The control unit acts as an intermediary that ensures safe operation despite the detachable water supply. It monitors whether the water container is properly installed through sensor feedback and controls the steam generator's power supply accordingly, preventing operation without proper water supply and thus maintaining reliability and safety while preserving maintenance ease.
Solution Approach 2:
The system performs self-checking through the sensor and control unit combination. The sensor automatically detects the water container's presence and the control unit automatically adjusts operation accordingly, eliminating the need for manual verification by the user and ensuring safety without compromising the detachable design's maintenance advantages.
