Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If classical tractors are used for semi-trailer transportation in factories, then the transportation task can be completed, but fuel consumption increases and maneuverability decreases
Solution Approach 1:
The patent replaces the mechanical tractor system with an automated guided vehicle system that uses sensors, controllers, and automated coupling devices. This substitution eliminates the need for human operators and traditional mechanical propulsion, replacing it with electric or hybrid propulsion systems that consume less energy and can operate autonomously in factory environments.
Solution Approach 2:
The transport vehicle is equipped with automated coupling devices that can independently couple to and decouple from semi-trailers without human intervention. The vehicle also includes obstacle detection sensors and navigation systems that enable it to autonomously navigate factory premises, eliminating the need for human operators and reducing energy consumption associated with manual operation.
2Productivity
If classical tractors are used for semi-trailer transportation in factories, then the transportation task can be completed, but maneuverability decreases due to vehicle size and design
Solution Approach 1:
The patent divides the transportation system into separate modular components: a compact guided vehicle unit and semi-trailers that can be coupled and decoupled independently. This segmentation allows the vehicle to be smaller and more maneuverable while maintaining full transportation capability when coupled to trailers. The modular design enables the vehicle to navigate tight factory spaces and then efficiently transport loads when coupled.
Solution Approach 2:
The guided vehicle is designed with dynamic coupling capabilities that allow it to automatically connect to and disconnect from semi-trailers. The vehicle includes adjustable coupling mechanisms and height-adjustable platforms that adapt to different trailer configurations, enhancing maneuverability while maintaining transportation effectiveness. The automated systems allow rapid reconfiguration for different operational needs.
3Productivity
If manual operation is used for tractor-driven semi-trailer transport, then transportation can be performed, but operational complexity and safety risks increase
Solution Approach 1:
The patent replaces manual mechanical operation with automated control systems that include sensors, processors, and automated coupling mechanisms. These systems handle coupling, navigation, obstacle detection, and decoupling operations automatically, reducing operational complexity while maintaining transportation functionality. The automated systems also improve safety by eliminating human exposure to moving parts and complex manual coupling procedures.
4Productivity
If classical tractors are used in factory premises, then semi-trailers can be transported, but the tractors are not suitable for indoor use due to size and emission constraints
Solution Approach 1:
The guided vehicle is designed as a universal platform that can operate in both indoor and outdoor factory environments. It features automated coupling devices compatible with standard semi-trailer kingpins, sensor systems for obstacle detection in confined spaces, and propulsion systems that meet indoor emission requirements. The vehicle can seamlessly transition between different operational environments and trailer types, enhancing versatility while maintaining transportation capability.
