Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators manually control multiple motors to operate excavating machine components, then the machine can be operated with full control, but operator errors occur frequently leading to machine damage and increased downtime
Solution Approach 1:
The system enables automatic operation of excavating machine components by using sensors to detect bank position and automatically controlling motors to maneuver the dipper, eliminating the need for continuous manual intervention and reducing operator error
Solution Approach 2:
The patent replaces manual mechanical control with an automated control system that uses sensors to detect bank position and automatically actuates motors, substituting human operation with an automated feedback-controlled mechanical system
2Reliability
If extensive training is provided to operators, then operator proficiency should improve, but operator errors still occur frequently causing damage and downtime
Solution Approach 1:
The system uses sensors to continuously detect the position of the bank relative to the dipper and provides feedback to the control system, which automatically adjusts motor control to maintain optimal positioning, eliminating reliance on operator judgment and reducing errors
Solution Approach 2:
The automated system monitors and adjusts dipper positioning independently without requiring ongoing operator attention or decision-making, preventing errors that occur despite training
3Reliability
If automatic control systems are implemented to reduce operator errors, then machine damage and downtime should decrease, but system complexity increases
Solution Approach 1:
The patent introduces a control system as an intermediary between sensors and motors, using a processor to interpret sensor data and generate appropriate motor control signals, managing complexity through modular system architecture
Solution Approach 2:
The system replaces complex manual coordination of multiple motors with an automated control algorithm that processes sensor input and generates coordinated motor commands, reducing operational complexity while maintaining full control capability
