Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional photovoltaic power generation systems are used, then electricity can be generated from renewable energy, but the system cannot produce sufficient amounts of renewable energy to replace nearly all primary energy needed on a national and global scale

Engineering Contradiction:
Improverenewable energy production capacityVSAvoidland area required
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent transitions from land-based photovoltaic systems to floating offshore photovoltaic systems, utilizing the three-dimensional space above water surfaces. This dimensional shift allows deployment over oceans and large water bodies, exponentially increasing the available area for energy generation without consuming additional land resources.

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

Solution Approach 2:

The floating offshore platform serves multiple functions: it generates electricity through photovoltaic panels, provides artificial reefs for marine ecosystems, and can be deployed in various water depths and locations. This multi-functionality increases energy production capacity while adding ecological and economic value.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If renewable energy is generated in large quantities, then carbon-free energy supply can be achieved, but the system lacks the capability to store and supply the produced renewable energy in a stable, low-cost, and high-quality manner

Engineering Contradiction:
Improveenergy supply stabilityVSAvoidenergy storage and distribution system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces ammonia as an intermediary energy carrier that converts intermittent renewable electricity into storable chemical energy. Ammonia synthesis plants convert excess electricity into ammonia, which can be stored indefinitely and transported via existing infrastructure, bridging the gap between variable generation and stable supply requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transforms energy from one form (electricity) to another (ammonia chemical energy) with different storage and transport characteristics. This parameter change enables long-term storage and flexible distribution, converting the temporal and spatial constraints of renewable energy into manageable parameters.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If floating offshore photovoltaic plants are deployed in equatorial waters with abundant sunshine, then sufficient renewable energy can be produced, but the system lacks infrastructure for energy transport and distribution to consumption areas

Engineering Contradiction:
Improveenergy generation quantityVSAvoidenergy transport and distribution infrastructure
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The system utilizes existing global ammonia infrastructure (production facilities, storage tanks, shipping routes, and distribution networks) to transport and deliver energy. By converting renewable electricity into ammonia, the system leverages established commercial infrastructure rather than requiring new dedicated transport infrastructure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of building new infrastructure to transport electricity directly from offshore plants to consumption areas, the system inverts the approach by converting energy into a storable chemical form (ammonia) at the generation site, then utilizing existing reverse logistics infrastructure for transport and distribution.

Inventive Principle:
Principle #13The other way round (Inversion)

4Productivity

If large-scale floating offshore photovoltaic systems are implemented, then global energy demands can be met, but the system complexity and management requirements increase significantly

Engineering Contradiction:
Improveglobal energy supply capacityVSAvoidsystem management and control complexity
Core Design Contradiction:

Solution Approach 1:

The patent divides the massive global energy system into modular floating offshore plants, each operating semi-independently. These modular units can be deployed incrementally across different locations, with each unit managing its own operations while contributing to the global energy portfolio, thereby reducing overall system management complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where ammonia production, storage levels, and distribution rates are continuously monitored and adjusted based on renewable energy generation patterns and consumption demands, enabling dynamic optimization of this complex multi-component system.

Inventive Principle:

AI summary

A carbon-free energy supply system generates hydrogen from electricity generated by a floating offshore photovoltaic power generation plant, synthesizes energy carriers using the hydrogen as a raw material, stores the energy carriers, converts the energy carriers into a predetermined energy form to supply the energy to each of the supply destination facilities. The floating offshore plant is composed of multiple photovoltaic panels, each of which is substantially hexagonal in plan view, by connecting the photovoltaic panels in a honeycomb structure in plan view. Each photovoltaic panel functions as a floating body, panel housings of the adjacent photovoltaic panels are capable of swinging relative to each other in a vertical direction, and each photovoltaic panel can be submerged and floated to a predetermined depth by pouring water into and draining water from the panel housing.
