Solution Overview
Problem
Conventional laundry dryers face issues with vibration and noise due to the deformation of thin rear panels, leading to misalignment of deceleration components and reduced reliability, and they struggle to control rotation speed and direction efficiently without a tub.
Innovation Solution
A laundry treating apparatus where the motor and decelerator are coupled and supported by a decelerator housing, which is fixed to the rear cabinet, maintaining coaxial alignment and reducing vibration transmission to the rear panel, allowing for stable rotation of the drum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver is fixed to the rear surface of the cabinet, then the driver can be stably supported, but the thin rear panel deforms and vibrates under load, causing misalignment of rotation components
Solution Approach 1:
A rigid support plate is introduced as an intermediary component between the driver and the cabinet rear panel. The support plate has a first fixing portion that attaches to the rear panel and a second fixing portion that secures the driver, thereby mediating the mechanical connection and preventing direct transmission of vibrational loads to the thin rear panel.
Solution Approach 2:
The support plate is installed in advance to cushion and distribute the mechanical loads from the driver and rotation shaft before they reach the rear panel. This preliminary structural reinforcement prevents deformation and vibration of the rear panel under operational conditions.
2Ease of manufacture
If the driver is fixed to the rear surface of the cabinet, then the driver can be installed, but vibration and noise occur due to rear panel deformation
Solution Approach 1:
The support plate serves as a mediator that isolates the driver from the cabinet rear panel, preventing vibration transmission. The driver can still be easily installed using the support plate as a mounting base, while the plate's rigid structure prevents the generation of harmful vibrations and noise.
3Reliability
If the driver is fixed to the rear surface of the cabinet, then the driver can be supported, but the rear panel receives excessive load from both the driver and drum
Solution Approach 1:
The load-bearing function is segmented between the support plate and the cabinet structure. The support plate carries the localized loads from the driver and rotation shaft, while the cabinet's main body supports the drum load, thereby distributing and reducing the stress on the thin rear panel.
Solution Approach 2:
The support plate acts as an intermediary load-bearing component that intercepts and distributes mechanical loads before they reach the rear panel, reducing the stress concentration on the thin panel material.
