Solution Overview

Problem

The complex structure of the electromotor's end covers in laundry machines, necessitated by the need for a mounting structure to secure the electromotor to the water container, results in high costs and limited material and production process options.

Innovation Solution

The electromotor design includes a controller and controller cover with a first and second end cover, where the controller cover has mounting parts to secure both the end cover and the water container, simplifying the structure and reducing the need for additional mounting structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electromotor housing is provided with a mounting structure to be secured with the water container, then the electromotor can be firmly mounted, but the structure of the end covers becomes complex

Engineering Contradiction:
Improvemounting firmnessVSAvoidend cover structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the mounting structure for the water container directly into the end cover of the electromotor housing. The end cover integrates both the structural covering function and the mounting function through built-in mounting holes and fixing mechanisms, eliminating the need for separate mounting brackets or additional structural components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The end cover is designed to perform multiple functions simultaneously: it serves as the protective housing cover, provides structural support, and incorporates the mounting interface for securing the electromotor to the water container. This multi-functional design reduces overall structural complexity while maintaining mounting reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the electromotor housing is provided with a mounting structure to be secured with the water container, then the electromotor can be firmly mounted, but the production cost increases

Engineering Contradiction:
Improvemounting firmnessVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The mounting structure is integrated into the end cover itself rather than being a separate component. This consolidation reduces the total number of parts that need to be manufactured, stored, and assembled, thereby lowering production costs while maintaining secure mounting capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The end cover serves multiple purposes including structural support, protection, and mounting functionality. By making the end cover multi-functional, the patent eliminates the need for additional specialized mounting components, reducing material costs and manufacturing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the electromotor housing is provided with a mounting structure to be secured with the water container, then the electromotor can be firmly mounted, but the selection of materials is restrained

Engineering Contradiction:
Improvemounting firmnessVSAvoidmaterial selection
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting functionality is merged into the end cover structure itself, allowing the same material to serve both structural and mounting purposes. This integration removes the constraint of needing separate mounting components made from specific materials, thereby broadening material selection flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The end cover is designed as a multi-functional component that can be made from various materials (metal, plastic, or composite) while still providing both structural support and mounting capability. This universality allows manufacturers to select materials based on cost, weight, or corrosion resistance requirements without compromising mounting firmness.

Inventive Principle:
Principle #6Universality (Multi-functionality)
