Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate external controllers are used for each robot, then control functionality is achieved, but controller size and system complexity increase
Solution Approach 1:
The patent merges the control functions of multiple robots into a single integrated controller. The controller is designed to control a first robot and at least one second robot simultaneously, eliminating the need for separate external controllers for each robot. This consolidation reduces system complexity while maintaining full control functionality across all robots.
2Reliability
If numerous cables are used for signal communication between controllers and robots, then control signals can be transmitted, but cable complexity and malfunction risk increase
Solution Approach 1:
The patent consolidates multiple signal communication cables into a single cable that carries signals between the integrated controller and the robots. This single cable replacement eliminates the need for numerous separate cables, reducing cable complexity and the risk of malfunctions while maintaining reliable signal transmission for controlling multiple robots.
3Reliability
If external controllers are installed separately from robots, then control independence is maintained, but mounting space and installation flexibility are limited
Solution Approach 1:
The patent integrates the controller within the robot structure itself, nesting the control system inside the robot rather than placing it externally. This nested configuration allows the controller to be mounted directly on or within the robot, improving installation flexibility and space utilization while maintaining control functionality through the integrated design.
