Solution Overview
Problem
Conventional laundry treating apparatuses face issues with misalignment and vibration of the housing during rotation, leading to unreliable clutch performance and increased noise and friction due to the misalignment of components and the need for additional space for the clutch mechanism.
Innovation Solution
The apparatus features a coupler positioned between bearings to support the housing, allowing it to rotate stably and preventing misalignment by placing the clutch above the lowermost end bearing, thus reducing the overall length and volume of the clutch and driver components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clutch mechanism is designed with additional space for component movement, then the coupler can be positioned to support the housing, but the overall length and volume of the clutch and driver components increase
Solution Approach 1:
The patent repositions the coupler from a horizontal arrangement to a vertical arrangement above the lowermost end bearing. This dimensional change allows the coupler to support the housing vertically while reducing the horizontal length of the clutch mechanism, effectively resolving the contradiction between reliability and volume.
Solution Approach 2:
The coupler is pre-positioned above the lowermost end bearing to provide preliminary support to the housing before rotation occurs. This preliminary positioning prevents misalignment and vibration during operation, ensuring reliable clutch performance without requiring excessive space.
2Stability of the object's composition
If the housing is supported by additional bearings, then misalignment and vibration are reduced, but the complexity of the clutch mechanism increases
Solution Approach 1:
The lowermost end bearing serves multiple functions: it supports the housing during rotation and provides a reference position for the coupler to prevent misalignment. This multi-functionality reduces the need for additional specialized components, thereby reducing overall complexity while maintaining stability.
Solution Approach 2:
The coupler acts as an intermediary element between the housing and the lowermost end bearing. It transmits the support function from the bearing to the housing, enabling stable operation without requiring direct complex connections between multiple bearings and housing components.
3Manufacturing precision
If the coupler is positioned above the lowermost end bearing, then the housing rotates stably without misalignment, but the overall length of the driver components increases
Solution Approach 1:
The patent transitions from a horizontal layout where the coupler would extend the length of the driver to a vertical layout where the coupler is positioned above the lowermost end bearing. This dimensional change achieves precise alignment and stable rotation while minimizing the horizontal length of the driver components.
