Problem

Existing hyperloop transportation systems face challenges in constructing tube segments due to their large size, especially on difficult terrains, requiring complex transportation and energy supply logistics, and necessitating frequent electrical certifications.

Innovation Solution

A method involving piers and girders to construct an above-ground transportation structure, allowing tube segments to be assembled under low air pressure, with girders forming rooftop pathways for easy transportation and assembly, eliminating the need for ground access and simplifying logistics.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveease of transportationVSAvoidadaptability to terrain
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveease of tube manufacturingVSAvoidcomplexity of energy supply
Core Design Contradiction:
Ease of manufactureVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If tube segments are made large to reduce quantity, then fewer segments need assembly, but transportation and handling become more difficult

Engineering Contradiction:
Improveassembly efficiencyVSAvoidease of handling
Core Design Contradiction:
ProductivityVSEase of operation

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action
