Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for generating electricity from fluid currents, such as ocean currents, do not utilize magnetic induction or trolleys propelled by blades along a track, which limits the efficiency and innovation in this field.
Innovation Solution
A system employing trolleys mounted on a closed-loop track using wheels or magnetic levitation, with adjustable blade orientation and spacing control, generates electricity through relative motion between magnets and a conductor within the track's magnetic field, allowing for efficient energy conversion from fluid currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional hydroelectric turbines with central shafts are used, then the structure is simple and easy to manufacture, but the efficiency of energy conversion is limited and the design is less innovative
Solution Approach 1:
The patent divides the traditional centralized turbine structure into multiple independent trolleys moving along a closed-loop track. Each trolley contains blades that independently convert fluid current energy into mechanical motion, which is then converted to electricity through magnetic induction. This segmentation allows for more efficient energy capture while maintaining manufacturing simplicity through modular components.
Solution Approach 2:
The patent replaces the traditional mechanical central shaft and generator system with a magnetic levitation-based system. Trolleys equipped with magnets move along a track containing conductive coils, generating electricity through electromagnetic induction without direct mechanical contact. This substitution eliminates friction losses and enables higher efficiency energy conversion.
2Ease of manufacture
If trolleys are mounted using wheels on the track, then the structure is simple and cost-effective, but friction losses reduce the efficiency of energy conversion
Solution Approach 1:
The patent replaces the wheel-based mechanical mounting system with magnetic levitation. Trolleys equipped with magnets are propelled along the track by electromagnetic forces from coils embedded in the track, eliminating physical contact and friction. This substitution dramatically reduces energy losses while maintaining ease of manufacture through the use of standard magnetic components.
Solution Approach 2:
The patent changes the fundamental operating parameter of the mounting system from mechanical contact (wheels) to magnetic field interaction (levitation). By transitioning from a contact-based system to a field-based system, friction losses are eliminated while the system remains manufacturable using conventional magnetic components and control systems.
3Ease of manufacture
If the outer diameter of the blade is limited by the inner diameter of the stator, then the manufacturing is simpler, but the energy generation capacity is reduced
Solution Approach 1:
The patent transitions from a two-dimensional constrained design (blade diameter limited by stator inner diameter) to a three-dimensional spatial arrangement. Multiple trolleys with blades operate simultaneously along a closed-loop track, utilizing the full volumetric space available. This dimensional change allows energy generation capacity to scale with the track circumference rather than being constrained by a single stator's inner diameter.
Solution Approach 2:
The patent segments the energy generation function across multiple independent trolleys distributed along the track. Each trolley-blade-stator assembly operates as an independent energy conversion unit, allowing the total power capacity to be the sum of multiple units rather than limited by a single large-diameter configuration. This segmentation enables scalable power generation without increasing individual component dimensions.

AI summary
An apparatus for generating electricity from fluid currents comprises a continuous loop structure and at least one blade movably mounted relative to the continuous loop structure and extending in a direction radially outward relative to the continuous loop structure, the at least one blade being configured to rotate about an axis of the continuous loop structure. The at least one blade may be configured to interact with fluid currents moving in a direction approximately parallel to the axis of the continuous loop structure to rotate the at least one blade about the axis of the continuous loop structure. At least a portion of the least one blade may intersect a plane of the continuous loop structure that is substantially perpendicular to the axis of the continuous loop structure. Rotation of the at least one blade may generate electrical energy.
