Electromotor Controller Cover Mounting to Simplify End Cover Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of an electromotor with a controller in laundry machines results in complex structures and high costs due to the need for a housing with a mounting structure secured to a water container, limiting material selection and increasing manufacturing complexity.
Innovation Solution
The electromotor design includes a controller cover with mounting parts that secure the controller and stator, allowing the housing to omit unnecessary mounting structures, simplifying the end cover design and reducing costs by directly attaching the mounting parts to the stator or controller cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing of the electromotor is provided with a mounting structure secured with the water container, then the electromotor can be fixed to the laundry machine, but the structure of the end covers becomes complex
Solution Approach 1:
The mounting structure is divided into two separate parts: a first mounting part integrated into the end cover and a second mounting part integrated into the controller cover. This segmentation allows each component to have a simpler, more focused structure while maintaining the overall fixing functionality when assembled together.
Solution Approach 2:
The first mounting part of the end cover and the second mounting part of the controller cover are combined during assembly to form the complete mounting structure. This merging approach distributes the structural complexity across multiple components rather than concentrating it in the end cover alone.
2Reliability
If the housing is provided with a mounting structure secured with the water container, then the electromotor can be fixed to the laundry machine, but the cost of the electromotor increases
Solution Approach 1:
Dividing the mounting structure into separate parts integrated into existing components (end cover and controller cover) avoids the need for additional separate mounting parts, thereby reducing manufacturing steps and costs while maintaining fixing reliability.
3Reliability
If the housing is provided with a mounting structure secured with the water container, then the electromotor can be fixed to the laundry machine, but the range of selection of materials is restrained
Solution Approach 1:
By integrating mounting parts into existing components rather than using a separate housing structure, the patent enables greater flexibility in material selection for each component based on its specific functional requirements, rather than being constrained by a single housing material choice.

AI summary
An electromotor and a laundry machine are provided. The electromotor has a controller and a controller cover. The controller is arranged on the controller cover. A first end cover and a second end cover of the electromotor are fixedly arranged on two opposite sides of a stator respectively. The controller cover is provided with a first mounting part and a second mounting part secured with a water container. The first end cover or the stator is provided with a third mounting part secured with the first mounting part. The third mounting part is arranged on the first end cover or the stator. The laundry machine has the electromotor.
