Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a human performs dangerous tasks directly, then task completion is immediate and direct, but the human is exposed to hazardous materials and physical injury risks
Solution Approach 1:
The patent introduces a robotic assembly as an intermediary device between the human operator and the hazardous environment. The robotic assembly performs the dangerous tasks while the human operates it remotely through the exoskeleton control system, thus protecting the human from direct exposure to hazards while maintaining operational capability
Solution Approach 2:
The patent replaces direct human mechanical action with a robotic mechanical system controlled by the exoskeleton. The robotic assembly's actuators and mechanisms perform the physical tasks that would otherwise require direct human intervention, substituting human mechanical effort with automated robotic execution under remote control
2Reliability
If a robotic assembly is used to perform dangerous tasks, then human safety is improved, but the system complexity increases
Solution Approach 1:
The exoskeleton apparatus serves multiple functions: it provides sensor input for control, delivers tactile feedback to the operator, and interfaces with the robotic assembly control system. This multi-functionality reduces the need for separate components and simplifies the overall system architecture despite the advanced capabilities provided
Solution Approach 2:
The patent implements a feedback loop where sensors on the robotic assembly detect task conditions and transmit this information through the exoskeleton to the operator. This feedback mechanism enables the operator to adjust control signals in real-time, simplifying the control process and improving system adaptability without increasing operational complexity
3Reliability
If remote control is implemented, then human exposure to hazards is reduced, but control precision may be compromised
Solution Approach 1:
The tactile feedback mechanism in the exoskeleton provides real-time sensory information about the robotic assembly's position, force, and environmental conditions directly to the operator's hand. This feedback enables precise control adjustments without the operator needing to be physically present, maintaining control accuracy while enabling remote operation
Solution Approach 2:
The patent replaces direct mechanical coupling between the operator and robotic assembly with a sensor-based control system. Sensors on the robotic assembly and in the exoskeleton substitute for direct mechanical feedback, transmitting control signals and sensory data electronically to maintain precise control at a distance
