Engineering Contradiction Analysis
1Area of stationary object
If multiple individual milling machines are used to mill parallel strips, then milling coverage is increased, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent combines multiple milling machines into a single integrated vehicle-mounted system with multiple milling heads arranged in parallel. This allows simultaneous milling of multiple parallel strips across the road surface, achieving the same milling coverage as multiple individual machines but with reduced labor intensity and time consumption since one vehicle performs the work of several machines
Solution Approach 2:
The milling vehicle is designed as a multi-functional platform that can simultaneously perform multiple milling operations on different road lanes. The system can mill parallel strips across multiple lanes in one pass, making a single vehicle universal enough to replace multiple specialized machines while improving operational efficiency
2Ease of operation
If manual guidance is used for milling machines, then operational flexibility is maintained, but positioning precision and safety are compromised
Solution Approach 1:
The patent incorporates optoelectronic detection systems that scan the road surface and provide real-time feedback to the control system. This allows the milling vehicle to automatically adjust its position and milling head locations based on detected road features, lane markings, and slope variations, achieving high positioning precision while maintaining operational flexibility through automated control
Solution Approach 2:
The milling system performs self-positioning and self-alignment using onboard sensors and control systems. The optoelectronic detection system automatically identifies the correct milling locations and guides the milling heads without requiring manual intervention, enabling the system to service itself in terms of positioning and alignment while improving both precision and safety
3Device complexity
If road surface is milled without precise leveling, then operational simplicity is maintained, but water drainage and road safety are compromised
Solution Approach 1:
The patent uses optoelectronic detection systems to continuously monitor road surface slopes and elevation changes. This feedback information is used by the control system to dynamically adjust the vertical position of milling heads, ensuring that milled strips are created at the correct depth and angle to promote proper water drainage while maintaining operational simplicity through automated control
Solution Approach 2:
The system dynamically changes the operational parameters of the milling heads based on real-time road condition detection. The vertical position, depth, and angle of milling heads are automatically adjusted according to detected slope variations and elevation changes, ensuring optimal drainage geometry without requiring complex manual operations
