Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monolithic manholes are used, then durability is improved, but storage and transportation efficiency deteriorates
Solution Approach 1:
The manhole is divided into multiple modular segments that can be stacked vertically during storage and transportation. Each segment contains connection features (dowel pins, clip bosses, hinges) that enable assembly into a complete manhole structure, allowing compact storage while maintaining durability through modular construction
2Reliability
If monolithic manholes are used, then durability is improved, but transportation efficiency deteriorates
Solution Approach 1:
The manhole structure is segmented into transportable modules that can be efficiently loaded and unloaded during installation. The modular design with interlocking connection features enables faster assembly compared to installing monolithic manholes, improving transportation and installation productivity
3Volume of stationary object
If segmented manhole segments are used, then storage and transportation efficiency is improved, but assembly complexity increases
Solution Approach 1:
Multiple connection features (dowel pins, clip bosses, hinges, gaskets) are integrated into a unified connection system that simplifies the assembly process. The interlocking design allows segments to be quickly joined together through straightforward mechanical connections, reducing assembly complexity despite the segmented structure
