Universal Outer Tub Connector for Direct and Belt-Drive Washers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric treating machines require separate outer tubs for direct and indirect driving motors due to shape differences, leading to high production costs and incompatibility, limiting the common use of outer tubs and increasing assembly complexity.
Innovation Solution
A fabric treating machine design featuring a connector with adjustable direct and indirect driver placements and reinforcement parts, allowing either direct or indirect driving motors to be connected to the same outer tub without modification, using a rotary shaft and pulley system for power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate outer tubs are used for direct and indirect driving motors, then the motors can be properly connected, but the production cost increases and the outer tub becomes incompatible across different driving types
Solution Approach 1:
The connector is designed with multiple functional areas including a direct driver placement area and an indirect driver placement area, allowing the same outer tub to accommodate both direct driving motors and indirect driving motors through a single universal connector structure
Solution Approach 2:
The connector is divided into distinct placement areas: a direct driver placement area for direct driving motors and an indirect driver placement area for indirect driving motors, with each area optimized for its specific motor type while maintaining overall compatibility
2Reliability
If separate outer tubs are designed for different motor types, then proper motor connection is achieved, but the production cost increases due to multiple tub variants
Solution Approach 1:
A single outer tub design with a universal connector that can accommodate both direct driving motors and indirect driving motors, eliminating the need to produce multiple outer tub variants and reducing manufacturing costs
3Adaptability or versatility
If the connector is designed to accommodate both direct and indirect driving motors, then outer tub compatibility is improved, but the connector structure becomes more complex
Solution Approach 1:
The connector is segmented into distinct placement areas for direct and indirect drivers, with each area having its own optimization features, allowing complex functionality to be organized in a modular and manageable way
Solution Approach 2:
The connector utilizes spatial arrangement and positioning in different areas to accommodate different motor types, using dimensional placement strategies to manage complexity while maintaining versatility

AI summary
A fabric treating machine according to the present invention comprises a connector which is disposed at an outer tub and is connected to a driving part which is disposed at either the center or the off-center position of the connector optionally. Therefore, not only the direct driving motor but the indirect driving motor can be disposed without change of the outer tub and the connector. Because the common use of the outer tub is possible regardless of the connecting method of the driving part, there are the advantages that the cost is reduced and productivity and assembly are improved.
