Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing testing solutions are used to capture motion data, then data can be collected, but the system is slow, not portable, inaccurate, and expensive requiring manual resetting
Solution Approach 1:
The system performs self-resetting automatically after each trial without requiring human intervention. The motion characterization processor detects when the robot completes a trial and automatically resets the system to its initial state, enabling continuous automated testing and eliminating manual resetting operations.
Solution Approach 2:
The patent replaces complex mechanical testing systems with an integrated electronic control system that uses sensors, processors, and automated control signals to characterize motion, making the system more portable and easier to deploy while maintaining measurement accuracy.
2Reliability
If manual resetting is required with each trial, then testing can be performed, but human intervention is needed to position, remove, or reposition obstacles
Solution Approach 1:
The system performs self-resetting automatically after each trial without requiring human intervention. The motion characterization processor detects when the robot completes a trial and automatically resets the system to its initial state, enabling continuous automated testing and eliminating manual resetting operations.
Solution Approach 2:
The motion characterization processor acts as an intermediary that coordinates between the robot, obstacles, and control system. It manages the entire testing sequence including obstacle positioning, trial execution, and automatic resetting, eliminating the need for manual human operations.
3Speed
If indeterminate latencies in data transmission occur, then data can be transmitted, but the quality of results is affected and effects are magnified with increased operating speeds
Solution Approach 1:
The system pre-synchronizes all sensors and data transmission channels before motion characterization begins. Time synchronization signals are established in advance to ensure that all measurements are timestamped with precise reference times, eliminating indeterminate latencies even at high operating speeds.
Solution Approach 2:
The system continuously monitors and compensates for data transmission timing variations in real-time. The motion characterization processor receives timing feedback from all sensors and adjusts measurements to account for any latency variations, ensuring accurate motion characterization regardless of robot speed.
