Segmented Motor Unit Housing for Low-Power Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor units are designed for high-power applications and are not suitable for low-power working units, as they are heavy and require a larger body housing.
Innovation Solution
A motor unit configuration with a body housing defined by two housings, an accommodating space between them, and a motor positioned within, allowing for a lighter and lower-power motor to be used, suitable for low-power working units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large motor is used to drive high-power working units, then the motor unit can handle high-power applications, but the size and weight of the motor unit increase
Solution Approach 1:
The body housing is divided into a first housing and a second housing that are coupled together, creating a segmented structure. This segmentation allows the housing to be optimized for lower-power applications while still providing adequate support and protection, thereby reducing the overall weight and size of the motor unit for low-power working units
Solution Approach 2:
The patent specifies that the motor has a maximum output ranging from 0.5 kW to 2.0 kW, representing a parameter change from high-power to low-power motor specifications. This parameter change enables the use of lighter motors suitable for low-power working units while maintaining the same body housing structure
2Power
If a large motor is used to drive high-power working units, then the motor unit can handle high-power applications, but the body housing size increases
Solution Approach 1:
The body housing is segmented into a first housing and a second housing coupled together, allowing for a more compact and efficient use of space. This segmented structure enables the same housing to accommodate both larger motors for high-power applications and smaller motors for low-power applications, reducing the required body housing volume for low-power units
Solution Approach 2:
The body housing structure with first and second housings is designed to be universal, capable of supporting motors across a range of power outputs (0.5 kW to 2.0 kW). This multi-functionality allows the same housing design to serve both high-power and low-power applications, optimizing space utilization

AI summary
A motor unit may be configured to drive a working unit. The motor unit may include: a body housing comprising a first housing and a second housing, wherein an accommodating space is defined between the first housing and the second housing, and the first housing and the second housing define an entire outer contour of the body housing; a motor positioned in the accommodating space; an output unit configured to be fixed to the working unit and drive the working unit when the motor operates; a battery terminal exposed to outside of the body housing and configured to be connected to a battery configured to supply power to the motor; and a control unit positioned in the accommodating space and configured to control the motor.
