Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bus system is used for data transmission between work vehicle and work device, then direct wired data transmission is achieved, but compatibility issues arise and considerable effort is required for retrofitting
Solution Approach 1:
The patent introduces a transponder as an intermediary device that mediates data transmission between the work vehicle and work device. Instead of requiring direct bus system connections between both components, the transponder acts as a universal intermediary that can be integrated into existing systems without requiring both parties to have compatible bus systems, thus resolving the compatibility issue while maintaining reliable data transmission
Solution Approach 2:
The patent replaces the mechanical/wired bus system connection with a radio frequency identification system. This substitution eliminates the need for physical connection of communication lines between work vehicle and work device, reducing retrofitting effort and compatibility requirements while maintaining data transmission functionality
2Reliability
If physical connection of communication lines is made between work vehicle and work equipment, then data transmission is established, but additional effort is required and failure-prone connections result
Solution Approach 1:
The patent replaces the mechanical connection of communication lines with a wireless radio frequency identification system. The transponder enables data transmission through electromagnetic fields without requiring physical connection of cables between the work vehicle and work equipment, eliminating connection effort and failure points while maintaining reliable data transmission
3Ease of operation
If constant driving speed is maintained, then operational simplicity is achieved, but precision of row spacing and plant spacing may be compromised under varying soil conditions
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor the actual position and spacing of rows and plants during field operations. This real-time data is fed back to the control system, which then adjusts the driving speed dynamically to maintain precise row and plant spacing, resolving the contradiction between simple constant speed operation and precision requirements under varying conditions
