Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual connection and disconnection of trailer lines is performed, then the process can be completed with simple equipment, but it increases connection time, causes wear and tear on components, and poses safety risks to operators
Solution Approach 1:
The patent replaces manual mechanical connection operations with an automated robotic arm mechanism. The robotic arm automatically connects and disconnects the three lines (parking brake, service brake, and electrical systems) between the tractor and trailer, eliminating the need for manual labor and reducing both connection time and safety risks to operators.
Solution Approach 2:
The system enables self-service automation where the robotic arm performs the connection and disconnection tasks autonomously based on sensor detection of trailer presence and position, reducing dependency on human operators and minimizing wear and tear through precise, consistent mechanical operations.
2Object-affected harmful factors
If robotic arm mechanisms are used for automatic connection, then safety risks and manual labor are reduced, but the cost of manufacture, maintenance, and repair increases significantly
Solution Approach 1:
The patent segments the automated connection system into a modular robotic arm mechanism with distinct functional components (connection head, positioning system, control unit). This segmentation allows for easier manufacturing, maintenance, and repair compared to a fully integrated automated system, as individual modules can be serviced independently without replacing the entire system.
Solution Approach 2:
The robotic arm serves as an intermediary device between the operator and the trailer connection process. By positioning the robotic arm as a mediating component, the system reduces direct human exposure to safety risks while maintaining cost-effectiveness through a simplified mechanical design that is easier to manufacture and maintain than more complex automated alternatives.
3Extent of automation
If a stationary robotic arm is used for connection, then automation is achieved at one position, but the system lacks versatility for trailers requiring movement within the yard
Solution Approach 1:
The patent incorporates a movable or repositionable robotic arm mechanism that can dynamically adjust its position and orientation to accommodate trailers at different locations within the yard. This dynamic capability allows the same automated system to serve multiple positions and handle trailers requiring movement, enhancing versatility while maintaining automation benefits.
