Engineering Contradiction Analysis
1Productivity
If traditional underground room construction methods are used, then structural strength and stability are achieved, but construction time and labor burden increase significantly
Solution Approach 1:
The underground room structure is divided into modular components: a plastic tube forming the main wall structure, plastic end walls for closure, and separate functional elements like ventilation ducts and cables that can be integrated into the hollow wall space. This segmentation allows for pre-fabrication and rapid assembly at the building site, significantly reducing construction time while maintaining structural integrity.
Solution Approach 2:
Functional elements such as ventilation ducts, electric cables, and water pipelines are nested within the hollow space of the plastic tube walls. This nesting approach integrates multiple functions into the structural components themselves, eliminating the need for separate installation processes and reducing overall construction complexity.
2Ease of operation
If plastic tube structure is used, then construction time is reduced and ease of installation is improved, but structural strength may be compromised
Solution Approach 1:
The plastic tube structure is designed as a composite system combining the plastic tube material with integrated hollow wall structures and reinforced end walls. The hollow walls provide both structural strength and pathways for functional elements, creating a composite structure that maintains strength while enabling easy installation of utilities.
Solution Approach 2:
The plastic tube is designed with a curved or cylindrical cross-section rather than flat walls. This curvature provides inherent structural strength to resist earth pressure and loading conditions, while the rounded shape is easier to manufacture and install compared to angular structures. The curved geometry naturally distributes stresses more effectively.
3Adaptability or versatility
If hollow walls are incorporated, then functional elements can be integrated and structure becomes lighter, but manufacturing complexity increases
Solution Approach 1:
The hollow walls serve multiple functions simultaneously: they provide structural strength, reduce overall weight of the structure, and create integrated pathways for ventilation ducts, electric cables, and water pipelines. This multi-functionality eliminates the need for separate structural and utility components, reducing overall system complexity despite the sophisticated wall design.
Solution Approach 2:
The structural walls and utility pathways are merged into a single integrated hollow wall structure. Instead of having separate structural walls and separate conduits for utilities, the hollow walls combine both functions, allowing functional elements to be routed through the wall structure itself during a single installation process.
