Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the original large-scale independent underground garage is directly destroyed and filled with soil layers to construct the road, then the road can be built, but it requires a large amount of project and a long construction period, and causes huge resource waste
Solution Approach 1:
The patent recovers and reuses the original underground garage structure by preserving the roof plate and constructing a road structure above it, rather than destroying the garage. This transforms the garage from a useless space into a functional road structure, achieving resource recovery and avoiding waste while improving construction efficiency
Solution Approach 2:
The road structure is divided into multiple sections (front straight section, middle transition section, rear double-deck road section) with different structural configurations. This segmentation allows optimized construction in each zone, improving overall construction efficiency while reducing resource waste through targeted reinforcement only where needed
2Productivity
If the original large-scale independent underground garage is filled with soil and then the new road is constructed, then the road can be built, but due to the settlement of the soil, the filled soil exerts tremendous earth pressure on the surrounding environment, and gaps will be generated between the top of the soil and the roof plate, and the strength of the soil is also greatly affected, such that the bearing capacity of the road will decrease and people's travel safety will be affected
Solution Approach 1:
The patent changes the physical parameters of the filling material from traditional soil to lightweight materials such as foamed concrete or graded crushed stones. This parameter change reduces the density and weight of the filling, thereby reducing earth pressure on the garage structure and eliminating gap formation, while maintaining adequate bearing capacity for road traffic safety
Solution Approach 2:
The patent uses composite material structures combining the original garage roof plate with reinforcement elements (steel bars, concrete layers) and lightweight filling materials. This composite structure enhances the overall strength and bearing capacity while reducing weight, ensuring travel safety without compromising construction efficiency
