Multi-Clothes Styler Hanger Antiphase Vibration Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-clothes styler systems, simultaneous vibration of hangers amplifies noise and reduces the lifespan of the equipment due to increased frequency of damage.
Innovation Solution
Implementing an antiphase control method where the vibration phase of one hanger is controlled to be antiphase with the other, with optional frequency and amplitude synchronization, using a control unit that adjusts vibration frequencies and amplitudes to prevent inphase vibration, and utilizing a hall sensor to measure hanger movement.

Engineering Contradiction Analysis
1Productivity
If multiple hangers in the multi-clothes styler system vibrate simultaneously, then the clothes treatment efficiency is improved, but the vibration amplifies to increase noise and reduce equipment lifespan
Solution Approach 1:
The control unit alternates the vibration operation of multiple hangers in sequential periods rather than simultaneous operation. The first hanger vibrates for a predetermined time, then stops, while the second hanger vibrates during the stop period of the first hanger. This periodic alternating action maintains high clothes treatment efficiency while preventing vibration amplification and noise increase.
Solution Approach 2:
The control unit implements preliminary coordination of vibration phases by detecting when the first hanger stops vibrating and immediately initiating vibration of the second hanger. This preliminary anti-action ensures that vibrations from multiple hangers do not occur simultaneously, preventing the harmful amplification effect while maintaining continuous clothes treatment productivity.
2Productivity
If hangers operate simultaneously to treat multiple clothes, then productivity increases, but vibration noise amplifies
Solution Approach 1:
The system uses periodic alternating vibration operation where hangers are activated in sequence rather than simultaneously. Each hanger vibrates for a predetermined duration, then stops while the next hanger begins vibration. This periodic action maintains high clothes treatment throughput while the sequential timing prevents noise amplification from simultaneous vibrations.
Solution Approach 2:
The control unit ensures continuous useful action by overlapping the vibration cycles of different hangers. When the first hanger stops vibrating, the second hanger immediately begins vibration, creating a continuous clothes treatment process. This continuity maintains productivity while the staggered timing eliminates simultaneous vibration noise amplification.

AI summary
Method for operating a multi-clothes styler system having a first styler (10) and a second styler (20) each with a hanger (15, 25) for applying vibration to clothes hung therefrom, including an antiphase control step for controlling the vibration phase of the second hanger (25) of the second styler (20) to be in antiphase with the vibration of the first hanger (15) of the first styler (10), if said first hanger (15) and said second hanger (25) are operated at the same time, and the vibration frequencies of the first hanger (15) and the second hanger (25) are the same, such that the noise produced from the vibration of the plurality of hangers (15, 25) is reduced.
