Solution Overview
Problem
Conventional hydropower stations are costly, complex, and environmentally disruptive, requiring careful sealing of underwater turbines and generators, which complicates maintenance and poses hazards to marine life, while also obstructing water transport and altering natural habitats.
Innovation Solution
A self-floating paddlewheel device with a bell-shaped housing and adjustable water level control, allowing the paddlewheel to rotate freely and maintain constant generator speed by controlling water flow and level, reducing friction losses and eliminating the need for stringent underwater sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional hydropower stations use underwater turbines and generators, then energy can be generated from river flow, but the turbines and generators must be carefully sealed to prevent water exposure, which complicates maintenance and increases cost
Solution Approach 1:
The generator is extracted from the underwater environment and placed in a dry, protected housing above water level. Only the paddlewheel remains immersed in water, while the generator operates in a sealed, accessible environment, eliminating the need for complex underwater sealing and enabling easy maintenance.
Solution Approach 2:
A housing structure acts as an intermediary between the underwater paddlewheel and the above-water generator. This housing transmits mechanical energy from the paddlewheel to the generator while protecting the generator from water exposure, serving as a protective mediator that enables both underwater energy capture and above-water generation.
2Power
If dams and reservoirs are constructed for hydropower generation, then energy can be produced, but these structures interfere with natural habitats, cause land loss, and pose hazards from dam failure
Solution Approach 1:
The hydropower device is extracted from the traditional dam-reservoir model and placed directly in the river flow. The paddlewheel captures energy from the current without requiring large reservoirs or dams, thereby generating power while preserving natural habitats and avoiding dam failure hazards.
Solution Approach 2:
The device segments the hydropower function into a localized paddlewheel unit that can be placed in the river flow rather than requiring a large-scale dam structure. This segmentation allows energy generation without the need for extensive reservoir construction, minimizing environmental disruption.
3Power
If large dams and reservoirs are built for hydropower, then energy generation is achieved, but the construction is expensive, long, and complicated
Solution Approach 1:
The complex dam and reservoir system is extracted and replaced with a simple paddlewheel device that can be installed directly in the river. This extraction of the essential energy-capturing function from the complex dam structure dramatically reduces construction complexity, cost, and time requirements.
Solution Approach 2:
Instead of building large dams to create reservoirs and then generate power, the invention inverts the approach by placing a simple paddlewheel directly in the river flow to capture energy from the current. This inversion eliminates the need for complex dam construction while achieving energy generation.
4Power
If turbines are placed underwater to capture river flow, then energy can be generated, but the rotating blades pose a hazard to marine life
Solution Approach 1:
The generator is taken out of the underwater environment and placed in a protected housing above water level. The paddlewheel remains immersed but its rotating blades are designed to be safe for marine life, while the generator operates safely above water, separating the energy generation function from the underwater hazard.
