Solution Overview

Problem

Hybrid airships face difficulties in maintaining generators in remote locations due to accessibility issues and vibrations from generators disrupting sensitive sensors, while existing solutions do not adequately address these challenges.

Innovation Solution

The hybrid airship design features generators remotely located from the gondola via an arm, allowing easy access for maintenance and reducing vibrations, which improves cooling efficiency and minimizes disruption to sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the generator is located inside the gondola, then the structure is compact, but the maintenance access is difficult and tedious

Engineering Contradiction:
Improvemaintenance accessVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The generator is extracted from the gondola interior and relocated to an external position on the buoyancy enclosure. This extraction resolves the maintenance access problem by allowing operators to reach the generator from outside the airship, eliminating the need to enter the confined gondola space for routine maintenance operations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A flexible connection system (comprising flexible cables and mechanical linkages) serves as an intermediary between the externally located generator and the gondola interior. This intermediary mechanism transmits power and control signals while accommodating the spatial separation, enabling the generator to be positioned optimally for maintenance access while maintaining functional integration with the airship systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the generator is attached directly to the gondola and buoyancy element, then the structure is simplified, but the maintenance operation remains complicated

Engineering Contradiction:
Improvegenerator maintenanceVSAvoidattachment structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The generator mounting system is segmented into distinct modular components: the generator unit itself, the attachment mechanism to the buoyancy enclosure, and the connection interface to the gondola. This segmentation allows the generator to be independently accessed, removed, and replaced without affecting the overall airship structure, significantly simplifying maintenance operations while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

3Temperature

If the generator is located at the back of the gondola, then the structure is compact, but the thermal cooling is not efficient

Engineering Contradiction:
Improvegenerator coolingVSAvoidstructural arrangement
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The generator is relocated from the confined three-dimensional space inside the gondola to an external position on the buoyancy enclosure surface. This dimensional relocation provides access to the surrounding atmospheric environment, enabling effective thermal cooling through natural convection and radiation to the ambient air, while the flexible connection system maintains the functional link to the gondola.

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

4Object-affected harmful factors

If the generator is located inside the gondola, then the structure is compact, but the vibrations disrupt sensitive sensors

Engineering Contradiction:
Improvesensor interferenceVSAvoidstructural arrangement
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The generator, which is a significant vibration source, is extracted from the gondola interior and positioned externally on the buoyancy enclosure. This physical separation removes the vibration source from proximity to the sensitive sensors located within the gondola, thereby eliminating the harmful vibrational interference while the flexible connections maintain operational functionality.

Inventive Principle:
Principle #2Taking out (Extraction)
