Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual connection and disconnection of refrigerated containers is performed, then human operators can directly control the connection process, but safety risks increase due to human presence in high-risk port areas with moving mechanical means
Solution Approach 1:
The system enables automated self-service connection and disconnection of refrigerated containers through robotic arms that autonomously perform plugging and unplugging operations, eliminating the need for human operators to physically approach containers in hazardous port areas with moving cranes and lifting equipment
Solution Approach 2:
The patent replaces manual mechanical operations with an automated robotic system featuring programmable arms equipped with specialized end-effectors that can grasp, position, and connect electrical plugs to container sockets, substituting human labor with automated mechanical systems
2Adaptability or versatility
If manual connection processes are used, then flexibility in handling different container types is maintained, but synchronization between container movement and electrical connection deteriorates, leading to temperature loss and goods deterioration
Solution Approach 1:
The system incorporates feedback mechanisms where sensors detect container position, movement status, and connection state in real-time, allowing the control system to adjust robotic arm movements and timing to achieve precise synchronization between container handling operations and electrical connection, preventing temperature fluctuations
Solution Approach 2:
The robotic system performs preliminary positioning and preparation actions before actual connection is needed, anticipating container arrival and movement patterns to ensure connectors are ready and positioned correctly, eliminating delays and ensuring immediate connection upon container arrival
3Extent of automation
If automated systems are implemented, then safety and synchronization are improved, but device complexity increases due to additional mechanical and control components
Solution Approach 1:
The robotic system is designed with multi-functional capabilities, where a single automated platform can handle multiple container types, perform both connection and disconnection operations, and integrate with existing port infrastructure, reducing overall system complexity through consolidation of functions
Solution Approach 2:
The complex automated system is divided into modular functional segments including robotic arm modules, sensing modules, control modules, and end-effectors, allowing independent development, testing, and maintenance of each component while reducing overall system complexity through manageable modularity
