Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operators control power machines from within an on-board operator cab, then control reliability is maintained, but operator flexibility and safety are limited
Solution Approach 1:
A remote control device with processor acts as an intermediary between the operator and the power machine control system. The processor receives control inputs from the operator via the remote device, analyzes these inputs for potential errors, and transmits corrected commands to the machine's control system. This intermediary layer enables remote operation while maintaining control reliability through signal analysis and correction.
2Ease of operation
If remote control operation is enabled, then operator flexibility and safety are improved, but control signal accuracy may deteriorate due to potential transmission errors
Solution Approach 1:
The processor in the remote control device implements feedback by analyzing control inputs received from the operator and comparing them against expected command patterns. When potential errors are detected in the control signals during transmission, the processor applies corrective actions based on this analysis, ensuring accurate interpretation of operator intent and maintaining control signal accuracy despite remote operation challenges.
3Measurement precision
If a remote control system with signal analysis is implemented, then control accuracy is improved, but device complexity increases
Solution Approach 1:
The processor in the remote control device performs multiple functions: receiving control inputs from various input devices, analyzing these inputs for errors, applying corrective actions, and transmitting commands to the power machine. By consolidating these diverse functions into a single multi-functional processor unit, the system achieves improved control accuracy without proportionally increasing overall system complexity.
