Road Paving Area Correction for Complex Edge Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road paving machines face challenges in constructing areas with complex edge shapes, such as those with stormwater inlets, as these areas are difficult to reflect accurately in design data, leading to inefficiencies and incomplete construction.
Innovation Solution
An information processing apparatus that specifies areas difficult to construct by analyzing the shape of the road edge and operating speed of the paving machine, and corrects the design data to exclude these areas, allowing for accurate and efficient construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the road paving machine attempts to construct areas with complex edge shapes (e.g., around stormwater inlets), then the construction coverage is improved, but the construction quality and completeness deteriorate due to the inability to accurately reflect these areas in design data
Solution Approach 1:
The system performs preliminary identification of difficult-to-construct areas by analyzing the relationship between the road edge shape and paving machine operating speed before construction begins. This allows the system to pre-calculate and mark areas that cannot be properly constructed, so that these areas can be excluded from the construction plan in advance, preventing quality issues rather than attempting problematic construction
Solution Approach 2:
The system extracts and identifies specific areas from the overall construction zone that are difficult to construct due to complex edge shapes and machine speed limitations. By separating these problematic areas from the constructible areas, the system can focus construction resources on suitable zones while excluding areas that would result in incomplete or poor-quality construction
2Loss of information
If the design data includes all areas of the road surface including complex edge shapes, then the completeness of design data is improved, but the construction efficiency deteriorates due to time spent on incomplete construction attempts
Solution Approach 1:
The system performs preliminary analysis of the road edge shape and calculates difficult-to-construct areas before construction begins. By identifying and excluding these areas in advance, the system creates an optimized construction plan that maintains completeness of the overall design while eliminating portions that would waste construction time and resources
Solution Approach 2:
Rather than attempting to construct the entire road surface area including problematic edge regions, the system deliberately constrains construction to only the suitable areas that can be properly paved by the machine. This partial action approach avoids the excessive action of attempting impossible constructions, thereby improving overall construction efficiency
3Productivity
If the road paving machine operates at higher speeds to improve productivity, then the construction speed is improved, but the ability to construct complex edge shapes deteriorates due to the machine's physical limitations
Solution Approach 1:
The system dynamically analyzes the relationship between the road edge geometry and the paving machine's operating characteristics. By calculating the interaction between edge shape complexity and machine speed, the system identifies regions where high-speed operation would fail to achieve proper construction, and excludes these regions from the construction plan to maintain overall productivity
Solution Approach 2:
The system applies different construction strategies to different regions of the road surface. Rather than using a uniform approach, it identifies local areas with complex edge shapes that are incompatible with high-speed paving and excludes only those specific regions, allowing the majority of the road surface to be constructed efficiently at high speed

AI summary
An information processing apparatus includes a controller circuit configured to: specify an area to be excluded from a road surface to be constructed by a road paving machine according to a change in a shape of an edge of the road surface to be constructed by the road paving machine, based on information on an operating speed of the road paving machine; and correct an area of the road surface to be constructed, based on the area to be excluded.
