Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If wind turbines use tall towers to increase blade length for higher power generation, then power generation capacity is improved, but construction costs and maintenance costs increase, and safety risks arise

Engineering Contradiction:

Improvepower generation capacityVSAvoidtower structure complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent removes the tower structure entirely from the wind turbine system. The blades are designed to rotate around a horizontal axis without requiring vertical support, extracting the problematic tower component while maintaining power generation capability through direct ground-level installation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the conventional vertical-axis configuration with tall towers, the patent inverts the approach by using horizontal-axis rotation at ground level. This inversion eliminates the need for tall towers while still achieving high blade length for power generation through the horizontal rotation mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If wind turbines rely on wind force to rotate blades, then operation is simple, but electricity generation is limited in low or no-wind conditions

Engineering Contradiction:

Improveoperational simplicityVSAvoidelectricity generation in low-wind conditions

Core Design Contradiction:

Ease of operationVSPower

Solution Approach 1:

The patent merges wind turbine technology with internal combustion engine principles by incorporating fuel combustion chambers at the blade roots. This combination allows the system to operate using fuel energy when wind is insufficient, while maintaining simple wind-driven operation when wind is available.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The blades are designed with dual functionality: they can be driven by wind force during windy conditions and by combustion gases during low-wind or no-wind conditions. This multi-functionality ensures continuous electricity generation regardless of wind availability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Power

If conventional wind turbines use separate gear boxes and generators in nacelles, then power generation is efficient, but device complexity and maintenance requirements increase

Engineering Contradiction:

Improvepower generation efficiencyVSAvoidnacelle component complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The patent merges the generator directly with the horizontal rotation axis, eliminating the need for separate gear boxes and nacelles. This integration simplifies the power transmission system while maintaining efficient electricity generation through direct coupling of the rotating blades to the generator.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An engine is disclosed. The engine includes a rotary hub enclosing a manifold, blades radially distributed around the rotary hub, a combustion chamber at a distal end of each blade, an axle or shaft joined or fixed to the hub, and a generator operably connected to the axle or shaft. Each blade has a passage for air to flow to the combustion chamber and a fuel distribution conduit therein/thereon. The manifold connects a fuel supply conduit to the fuel distribution conduits. Each combustion chamber is configured to receive fuel and air from the corresponding fuel distribution conduit and passage, burn or detonate the fuel, and direct heated or expanded air and combustion gases in a direction that rotates the blades and the hub. The axle or shaft is configured to rotate with the hub. The generator is configured to convert a torque from the axle or shaft to electricity.
