Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tube segments are transported to construction site by vehicle, then assembly can be performed, but transportation becomes difficult on steep or difficult terrains
Solution Approach 1:
The tube structure is divided into multiple tube segments that are assembled in-situ on the construction site. Each tube segment is further divided into multiple girder components that can be transported separately and assembled using the rooftop transportation pathway, making the system adaptable to difficult terrains while maintaining ease of transportation.
Solution Approach 2:
The invention introduces a rooftop transportation pathway that operates in the vertical dimension (above ground level) to transport girder components along the longitudinal axis. This eliminates the need for ground-level transportation infrastructure, enabling construction on steep or inaccessible terrains where traditional ground-based transportation would be impossible.
2Ease of manufacture
If movable fabrication machine is used to manufacture tubes on land, then tube segments can be produced, but energy supply and electrical certifications become complex
Solution Approach 1:
The rooftop transportation pathway system is self-powered through photovoltaic panels integrated into the pathway structure. The pathway generates its own electrical energy to power the transportation vehicles and assembly mechanisms, eliminating the need for external energy supply infrastructure and complex electrical certifications.
Solution Approach 2:
The invention replaces traditional mechanical transportation systems (requiring engines, fuel, and complex power distribution) with a photovoltaic-powered electromagnetic propulsion system. The transportation vehicles are moved along the rooftop pathway using electromagnetic forces generated by photovoltaic panels, simplifying the energy supply system.
3Productivity
If tube segments are made large to reduce quantity, then fewer segments need assembly, but transportation and handling become more difficult
Solution Approach 1:
Each tube segment is divided into multiple smaller girder components that can be easily transported and handled. These girder components are assembled in-situ on the rooftop pathway to form complete tube segments, combining the benefits of smaller component handling with efficient assembly through the automated rooftop transportation system.
Solution Approach 2:
Girder components are prepared and positioned in advance on the rooftop pathway before final assembly into tube segments. This preliminary positioning allows for efficient organization and sequencing of components, maintaining high assembly productivity while working with smaller, more manageable component sizes.
