Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor units, such as servo amplifier-integrated servomotors, face issues with wire management, interference, noise, and heat dissipation, which affect assembly quality and efficiency, and the size of articulated robots when the drive circuit is integrated within the arm, limiting movement range.
Innovation Solution
A motor unit configuration that includes a separate amplifier section with a heat dissipating member, a bound power line, and a waterproof cover, allowing for improved heat management and flexibility in assembly, while preventing power line interference and noise, and reducing the motor's influence on the amplifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the amplifier section is integrated inside the arm with the motor, then the device complexity is reduced, but the arm size increases and the range of movement is narrowed
Solution Approach 1:
The amplifier section is separated from the motor and placed in a different location (base or separate housing), dividing the integrated system into independent components. This reduces the volume of the moving arm while maintaining the functional integration through external connection.
2Ease of manufacture
If the power line is not bound to the amplifier cover, then the ease of assembly is improved, but the power line interferes with other objects and noise increases
Solution Approach 1:
The power line is pre-bound to the amplifier cover during assembly preparation, ensuring proper positioning before final assembly. This preliminary action prevents interference with other objects and reduces noise while maintaining assembly efficiency.
3Device complexity
If the heat dissipating member is not attached to the motor, then the device complexity is reduced, but the heat management becomes insufficient
Solution Approach 1:
The heat dissipating member acts as an intermediary component attached to both the motor and the amplifier cover, facilitating heat transfer from the motor to the amplifier section and ultimately to the surrounding environment, improving heat management without significantly increasing complexity.
4Productivity
If the amplifier section is placed close to the motor, then the productivity is improved, but the vibration and heat from the motor influence the amplifier
Solution Approach 1:
The amplifier section is extracted from the immediate vicinity of the motor and positioned in a separate location, removing it from the harmful environment of motor vibration and heat while maintaining functional proximity through external connections.
