Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If gangplanks or rigid structures are used for transferring people and goods, then stability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent applies dynamics by replacing static gangplanks with a mobile robotic platform that can autonomously navigate and position itself. The robotic arm with multiple degrees of freedom provides dynamic adjustment capabilities, allowing the system to adapt to varying vessel positions and conditions while maintaining stability during operation.
Solution Approach 2:
The patent substitutes traditional mechanical gangplank systems with an autonomous robotic system equipped with sensors, actuators, and control algorithms. This replacement reduces mechanical complexity by eliminating the need for complex hinge mechanisms, counterweights, and manual operation systems while improving overall system intelligence and adaptability.
2Strength
If permanent connections or rigid structures are used, then structural strength is improved, but adaptability and ease of installation deteriorate
Solution Approach 1:
The robotic platform provides dynamic adaptability through its ability to move, reposition, and adjust its configuration in real-time. The system can accommodate different vessel types, sizes, and positions without requiring permanent installations, while maintaining structural strength through controlled operation and automated positioning mechanisms.
Solution Approach 2:
The autonomous robotic system performs self-positioning and self-adjustment without requiring permanent connections or external assistance for installation. The platform can independently navigate to the vessel, establish connection, and adapt to operational conditions, eliminating the need for complex installation procedures while maintaining structural integrity during use.
3Adaptability or versatility
If bulky systems are used for mixed use (people and goods), then versatility is improved, but ease of operation and space requirements worsen
Solution Approach 1:
The robotic platform autonomously performs navigation, positioning, and operation tasks without requiring complex manual control or extensive operational procedures. The integrated sensor systems and control algorithms enable the platform to self-adjust for different cargo types and passenger needs, simplifying operation while maintaining versatility for mixed-use applications.
Solution Approach 2:
The robotic system is designed with universal capabilities to handle both personnel and goods transport through its adaptable platform configuration, sensor systems, and control mechanisms. The same platform can accommodate wheelchairs, cargo containers, or passenger groups without requiring separate specialized equipment, thereby simplifying operation across diverse applications.
4Device complexity
If systems with limited stability are used, then device complexity is reduced, but operational safety deteriorates
Solution Approach 1:
The robotic platform incorporates sensor systems that continuously monitor position, orientation, and operational conditions, providing real-time feedback to the control system. This feedback mechanism enables automated adjustments to maintain stability and safety during operation, with the system capable of detecting and responding to changing conditions without increasing overall device complexity.
Solution Approach 2:
The system uses dynamic control mechanisms to actively maintain stability during operation, with the robotic arm and platform capable of real-time adjustment in response to external forces or position changes. This dynamic stabilization approach ensures operational safety while avoiding the need for overly complex static support structures.
