Solution Overview
Problem
Existing laundry treating apparatuses face challenges in minimizing durability reduction of power transmitters and fixed panels due to vibration issues during drum rotation, leading to potential damage and increased manufacturing costs.
Innovation Solution
The apparatus incorporates a power transmitter with a housing mounting unit that includes a support body fixed to a rotatable fixed panel, a gear unit for transmitting rotational motion, and a displacement limiter to control the rotation angle, along with a damper to absorb vibrations, ensuring effective assembly and reduced stress on the power transmitter and fixed panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the thickness of the support body is increased to suppress vibration of the drying drum, then vibration attenuation is improved, but manufacturing cost and weight of the apparatus increase
Solution Approach 1:
The support body is constructed using composite materials, specifically a combination of a rigid framework and vibration-absorbing materials. This allows the support body to maintain structural integrity and vibration suppression capabilities while reducing overall weight compared to a purely thick rigid structure.
Solution Approach 2:
The patent changes the structural parameters of the support body by introducing a hollow internal structure with reinforcing ribs. This modifies the density and structural distribution of material, achieving optimal vibration suppression with reduced weight compared to a solid thick structure.
2Stability of the object's composition
If the thickness of the support body is increased to suppress vibration of the drying drum, then vibration attenuation is improved, but manufacturing cost increases
Solution Approach 1:
The support body utilizes composite material construction that balances vibration suppression performance with manufacturing cost. The combination of standard rigid materials and cost-effective vibration-absorbing materials achieves the required stability without the high costs associated with purely thick solid structures.
Solution Approach 2:
By optimizing the thickness and structural configuration parameters of the support body, the patent achieves effective vibration suppression at a reduced material quantity, thereby lowering manufacturing costs while maintaining adequate vibration attenuation performance.
3Adaptability or versatility
If a reducer is used to connect the rotor with the drying drum, then control over number of rotations and rotation direction is improved, but assembly difficulty increases and durability reduction occurs
Solution Approach 1:
The patent introduces a belt as an intermediary power transmission element between the motor and drying drum, replacing the problematic reducer assembly. This belt-driven system provides the necessary rotation control while eliminating the assembly difficulties and durability issues associated with reducers.
4Adaptability or versatility
If a reducer is used to connect the rotor with the drying drum, then control over number of rotations and rotation direction is improved, but assembly difficulty increases
Solution Approach 1:
The belt serves as a simple intermediary that easily transmits power from the motor to the drying drum. This eliminates the complex assembly procedures required for reducers, making the system easier to manufacture and assemble while maintaining rotation control capabilities.
