Innovation Solution
A clothes treatment apparatus with a driver that includes a motor and a vibrating body, allowing the hanger bar to reciprocate with varying amplitudes and periods, minimizing unnecessary vibration and optimizing the driving force for effective clothes management functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the rotation speed of the driver is increased to decrease the period of the hanger bar, then the frequency of reciprocation is increased, but the amplitude of the hanger bar cannot be maintained due to physical limitations
Solution Approach 1:
The driver is designed with variable speed capability, allowing the rotation speed to be dynamically adjusted based on the required reciprocation frequency and amplitude. The control unit varies the rotation speed within a range of 50 to 200 rpm depending on the selected clothes management function, enabling the system to maintain optimal amplitude while achieving the desired reciprocation period.
2Productivity
If the amplitude of the hanger bar is increased to improve clothes management functions, then the effectiveness of dust removal and wrinkle removal is enhanced, but unnecessary vibration and noise are generated
Solution Approach 1:
The system changes the operational parameters of the driver by adjusting both the rotation speed and the corresponding reciprocation amplitude according to the selected clothes management function. The control unit stores multiple sets of parameter combinations (frequency and amplitude) for different functions such as dust removal, wrinkle removal, and drying, selecting the optimal parameters for each specific task to maximize effectiveness while minimizing unnecessary vibration and noise.
3Device complexity
If the hanger bar is designed to reciprocate with fixed amplitude and period, then the structure is simple, but the performance of various clothes management functions cannot be optimized
Solution Approach 1:
The driver and control unit are designed with multi-functionality to perform various clothes management functions including dust removal, wrinkle removal, and drying. The control unit stores multiple sets of reciprocation parameters (frequency and amplitude) that can be selected based on the required function, allowing a single hanger bar system to optimize performance across different applications without requiring multiple separate mechanisms.
