Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots have a split design for controllers and drivers, which leads to space inefficiency, complex signal transmission, and heat dissipation issues, making them unsuitable for narrow spaces and prone to overheating.
Innovation Solution
Integration of a driver controller board with a control module and drive module on a substrate, mounted on the robot's arm body, including a heat sink for effective heat dissipation and a communication module for network connectivity, allowing for scattered control devices and simplified connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the controller and driver are mounted separately on the base, then the signal transmission connection is complicated and heat dissipation is difficult, but the robot structure is conventional and easy to manufacture
Solution Approach 1:
The patent combines the controller and driver into a single integrated board, merging previously separate components (controller module, driver module, and communication module) into one unified structure mounted on the arm body. This integration simplifies signal transmission connections by eliminating multiple separate mounting points and connection interfaces on the base, directly resolving the technical contradiction between device complexity and ease of manufacture.
2Area of stationary object
If the controller and driver are mounted separately on the base, then the base takes up a lot of space and consumes installation accessories, but the robot can be manufactured conventionally
Solution Approach 1:
The patent merges the controller and driver onto a single integrated board that is mounted on the arm body rather than the base. This consolidation reduces the area occupied on the base and minimizes the number of installation accessories required, as one integrated board replaces multiple separate components that would otherwise require individual mounting space and fixtures on the base structure.
Solution Approach 2:
The patent relocates the control components from the base (horizontal plane) to the arm body (vertical/different spatial dimension). This dimensional shift moves the integrated board to a different spatial location, effectively reducing the base area occupation while maintaining conventional manufacturing approaches for the arm body mounting.
3Loss of substance
If the controller and driver are mounted separately on the base, then the installation accessories are consumed heavily, but the robot structure is conventional
Solution Approach 1:
The patent combines multiple components (controller, driver, communication module) into one integrated board, which reduces the number of installation accessories needed. Instead of requiring separate mounting brackets, fasteners, and connection interfaces for each component on the base, the single integrated board requires one set of mounting hardware, directly reducing accessory consumption while maintaining conventional manufacturing practices.
4Temperature
If the controller and driver are mounted separately on the base, then the heat dissipation is difficult and localized overheating occurs, but the robot can be manufactured conventionally
Solution Approach 1:
The patent integrates the controller and driver on the same board mounted on the arm body, which consolidates heat-generating components into a single location with dedicated heat dissipation structures. This integration allows for more effective thermal management through centralized heat sinks and airflow paths, preventing localized overheating that occurs when components are分散ly mounted on the base, while still using conventional manufacturing methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the volume of the base, improves heat dissipation, and allows the robot to operate reliably in smaller spaces while maintaining flexibility and ease of use.
Implementation Method 1
the driver controller integrated board further includes a heat sink, where the heat sink fits the substrate
Implementation Method 2
an in-board heat sink is disposed between the first side and the second side of the substrate and is capable of dissipating heat from the first control part, the second control part, the drive module, and the first communication module
Implementation Method 3
a cooling fan disposed at the circumference of the substrate, where the cooling fan can improve the airflow speed inside the cooling fin, thereby improving the heat dissipation effect
