Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the rotation speed of the driver changes to vary the period or frequency of the hanger bar, then the clothes treatment effectiveness is improved, but the amplitude of the hanger bar cannot be adjusted due to physical limitations
Solution Approach 1:
The patent applies dynamics by making the amplitude of the hanger bar adjustable through a variable amplitude driver mechanism. The driver includes an eccentricity adjustment mechanism that allows the amplitude to be changed dynamically during operation, enabling adaptation to different clothes treatment requirements while maintaining effective treatment through speed variation.
2Device complexity
If the hanger bar reciprocates with constant amplitude, then the mechanical structure is simple, but unnecessary vibration and noise occur that can damage the product
Solution Approach 1:
The patent applies periodic action by implementing variable amplitude reciprocating motion of the hanger bar. The driver mechanism allows the amplitude to be adjusted periodically or continuously, enabling the system to reduce amplitude during certain phases of operation to minimize unnecessary vibration and noise while maintaining effective treatment during active phases.
3Productivity
If the hanger bar operates at high frequency for effective dust removal, then the dust removal efficiency is improved, but the energy consumption increases
Solution Approach 1:
The patent applies parameter changes by enabling dynamic adjustment of both frequency and amplitude parameters of the hanger bar reciprocating motion. The system can operate at high frequency with optimized amplitude to achieve effective dust removal while managing energy consumption, and can switch to lower frequency modes when high-speed treatment is not required.
4Reliability
If the hanger bar amplitude is increased for better wrinkle removal, then the wrinkle removal effectiveness is improved, but the risk of product damage increases
Solution Approach 1:
The patent applies dynamics by implementing a variable amplitude driver that allows the hanger bar to operate at high amplitude when wrinkle removal is needed, while providing the capability to reduce amplitude to prevent product damage. The control system can dynamically adjust the amplitude based on the treatment requirements and fabric sensitivity.
