Engineering Contradiction Analysis
1Reliability
If maximum power values are used for peripheral components for safety reasons, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning from static maximum power settings to dynamic power adjustment. The control device continuously adapts the power output of peripheral components based on real-time robot pose, velocity, acceleration, and task requirements, ensuring safety while minimizing energy consumption throughout the robot's operational cycle
Solution Approach 2:
The patent implements parameter changes by modifying power output levels based on varying operational conditions. The control device adjusts power parameters dynamically according to robot state (position, velocity, acceleration) and task demands, replacing fixed maximum values with adaptive parameter sets that maintain safety margins while reducing overall energy consumption
2Use of energy by moving object
If power output of peripheral components is reduced to minimize energy consumption, then energy efficiency is improved, but reliability may deteriorate
Solution Approach 1:
The patent applies feedback by implementing a control device that continuously monitors robot state (pose, velocity, acceleration) and task requirements, then adjusts peripheral component power output accordingly. This closed-loop approach ensures that power reduction does not compromise reliability, as the system responds to changing conditions in real-time to maintain adequate holding power when needed
Solution Approach 2:
The patent implements preliminary action by pre-calculating or pre-planning power adjustments based on known robot trajectories and task sequences. The control device prepares appropriate power levels in advance for upcoming operational phases, ensuring that sufficient holding power is available when required while minimizing energy consumption during phases where full power is not needed
3Ease of operation
If peripheral components are adapted rudimentarily to process boundary conditions, then ease of operation is maintained, but energy optimization is insufficient
Solution Approach 1:
The patent applies self-service by implementing an automated control device that independently performs complex power optimization calculations and adjustments. The system self-regulates peripheral component power based on robot state and task requirements without requiring manual intervention, maintaining ease of operation while achieving sophisticated energy optimization that would be impossible through rudimentary adaptation
