Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the rotation speed of the driver changes to vary the period of the hanger bar, then the frequency of hanger bar movement changes, but the amplitude cannot be adjusted due to physical limitations
Solution Approach 1:
The patent applies dynamics by making the driver system adjustable and adaptable. The driver includes adjustable components that allow both the period and amplitude of hanger bar reciprocation to be modified according to different clothes treatment requirements, transforming a static system into a dynamic one that can adapt to various operational conditions.
Solution Approach 2:
The patent implements parameter changes by enabling independent adjustment of both period and amplitude parameters of the hanger bar reciprocation. The driver system allows modification of rotational speed to control period while simultaneously adjusting eccentricity or other mechanical parameters to control amplitude, providing versatile control over movement characteristics for different clothes management functions.
2Device complexity
If the amplitude of the hanger bar is kept constant, then the structure is simple, but the period cannot be decreased or frequency increased beyond physical limits
Solution Approach 1:
The patent makes the driver structure dynamically adjustable rather than fixed. By incorporating adjustable mechanisms that allow modification of both amplitude and period parameters, the system can achieve higher frequencies when needed while maintaining structural integrity, eliminating the trade-off between structural simplicity and performance capability.
3Object-affected harmful factors
If the hanger bar vibrates in directions other than the movement direction, then unnecessary vibration and noise occur, but the driving force required to move the hanger bar increases
Solution Approach 1:
The patent applies local quality by ensuring that the vibration and movement of the hanger bar are concentrated and directed specifically along the intended reciprocation path. The driver mechanism is designed to minimize off-axis vibrations through proper alignment and configuration of moving parts, thereby reducing unnecessary vibration and noise in directions other than the primary movement direction.
4Productivity
If the amplitude and period of the hanger bar are not optimized for specific clothes management functions, then the apparatus cannot effectively perform dust removal, wrinkle removal, or moisture control
Solution Approach 1:
The patent implements parameter changes by providing a control system that allows independent adjustment of amplitude and period parameters according to different clothes management functions. The driver can be configured with specific amplitude and period settings optimized for dust removal, wrinkle removal, or moisture control, enabling the apparatus to adapt its mechanical characteristics to match the requirements of each specific function.

AI summary
A clothes treatment apparatus includes a cabinet including an inlet, a first chamber positioned inside the cabinet and defining a space for accommodating clothes through the inlet, and a hanger bar positioned in the first chamber and configured to hold clothes accommodated in the first chamber. The apparatus further includes a driver including: a motor configured to generate torque; a vibrating body configured to support the motor and vibrate alternately in opposite rotation directions by rotation of the motor; and a motion converter configured to rotate together with the vibrating body and convert the vibration of the vibrating body in connection with the hanger bar such that the hanger bar reciprocates along a predetermined movement direction. The hanger bar is configured to reciprocate with different amplitudes and periods depending on a number of times that the motor rotates.
