Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-fabricated pavement slab assemblies with integrated cable bearing elements are used, then installation time and complexity are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The cable bearing element is pre-positioned within the pavement slab assembly during manufacturing, allowing the slab to be installed as a complete unit. This preliminary positioning action eliminates the need for complex on-site modifications and reduces installation time while maintaining precise positioning through controlled factory conditions.
Solution Approach 2:
The pavement slab assembly is manufactured as a segmented pre-fabricated unit with the cable bearing element integrated into specific regions. This segmentation allows for standardized production with precise positioning in the factory setting, while the entire assembly can be rapidly installed as a complete module on-site.
2Adaptability or versatility
If complex on-site installation and modification of route composition is required, then adaptability to existing routes is improved, but device complexity and installation time increase
Solution Approach 1:
The pavement slab assembly is designed as a universal unit that can be installed on various existing route types without requiring complex modifications. The standardized design with integrated cable bearing elements provides multi-functionality, serving both structural and electrical purposes across different route configurations.
Solution Approach 2:
All necessary modifications and integrations are performed in advance during factory manufacturing of the pavement slab assembly. The cable bearing element is pre-integrated into the slab structure, eliminating the need for complex on-site modifications and reducing installation complexity to simple placement and connection operations.
3Ease of operation
If electric lines are positioned after pavement installation, then ease of operation during installation is improved, but positioning precision and energy transfer efficiency decrease
Solution Approach 1:
The cable bearing element is pre-positioned within the pavement slab assembly during manufacturing, establishing precise positioning for the electric lines before the slab is installed. This preliminary positioning ensures accurate alignment and optimal energy transfer efficiency, while the pre-integrated design simplifies the installation process by eliminating subsequent positioning operations.
Solution Approach 2:
The cable bearing element and pavement structure are merged into a single integrated assembly, with the cable bearing element embedded within the pavement material. This merging ensures that the electric lines maintain precise positioning relative to the pavement surface, optimizing energy transfer efficiency while simplifying installation as a complete unit.
