Control Circuit Board Layout for Easier Drive Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot controllers require high-precision relative positioning of the control circuit board and power supply circuit board, which reduces productivity due to the need for precise alignment of multiple drive circuit boards.
Innovation Solution
The drive circuit board is held on the control circuit board in a posture that rises from its surface via connections between the signal and power input/output connectors, eliminating the need for high-precision relative positioning of the control and power supply circuit boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive circuit board is bridged between the control circuit board and the power supply circuit board to enable connections, then the internal structure of circuit boards is simplified, but high-precision relative positioning is required which reduces productivity
Solution Approach 1:
The control circuit board serves as an intermediary that integrates both signal and power connections. The drive circuit board connects to the control circuit board which then interfaces with the power supply circuit board, eliminating the need for direct bridging between control and power supply boards. This intermediary approach simplifies the overall structure while reducing positioning requirements.
Solution Approach 2:
The signal output connector and power output connector are integrated on the same control circuit board. By merging the functions of signal transmission and power distribution on a single board, the system reduces the number of separate connections needed and eliminates the requirement for high-precision relative positioning between multiple boards.
2Adaptability or versatility
If multiple drive circuit boards are provided to drive multiple motors individually, then motor control capability is improved, but high-precision relative positioning of multiple boards is required which reduces productivity
Solution Approach 1:
The control circuit board is designed with universal connectivity features that can accommodate multiple drive circuit boards. Each drive circuit board connects to the control circuit board through standardized signal and power connectors, allowing multiple motors to be controlled individually without requiring complex high-precision positioning arrangements.
3Reliability
If relative positioning is performed with high precision to achieve proper connection, then connection reliability is improved, but manufacturing cost and time increase
Solution Approach 1:
The connection system is segmented into independent modular connectors on the control circuit board. The signal output connector and power output connector are separate, easily connectable components that do not require high-precision relative positioning. This segmentation allows for simpler, more cost-effective manufacturing while maintaining reliable connections.
