Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind turbines positioned between lanes to capture wind from passing vehicles suffer from low energy yield due to the large spacing required to avoid mutual interference, leading to inefficient energy conversion.
Innovation Solution
A multi-turbine wind drive system, Metuwak, where wind turbines are arranged in a row on a support scaffolding with a rotary transmission mechanism, utilizing a boostal gear to combine the torque from multiple turbines into a single output, allowing for efficient energy conversion and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind turbines are positioned at large intervals of at least 10 m to avoid mutual interference, then the turbines can operate reliably, but the energy yield becomes relatively low
Solution Approach 1:
The patent combines multiple wind turbines (at least two) into a single integrated system that shares common components including a single support frame, common bearing, and shared rotary transmission mechanism. This merging allows the turbines to be positioned closer together (reducing the 10m spacing requirement) while maintaining operational reliability through the shared structural support and transmission system.
Solution Approach 2:
The common output shaft serves multiple functions: it receives torque from multiple turbine rotors simultaneously and transmits the combined torque to the rotary transmission mechanism. This multi-functional design enables the system to process energy from multiple turbines through a single transmission path, increasing overall energy yield without requiring separate transmission systems for each turbine.
2Productivity
If multiple wind turbines are arranged closely together, then the energy yield increases, but mutual interference between turbines occurs
Solution Approach 1:
By merging multiple turbines into a single integrated system with shared support structures and transmission mechanisms, the patent enables close spacing of turbines without mutual interference. The common bearing and support frame provide stable structural support that prevents the interference problems that would occur with independently positioned turbines placed close together.
3Productivity
If a rotary transmission mechanism is used to combine torque from multiple turbines, then energy conversion efficiency increases, but the device complexity increases
Solution Approach 1:
The patent merges multiple turbine power streams into a single rotary transmission mechanism that processes the combined torque from all turbines. This consolidation achieves efficient energy conversion by utilizing a unified transmission path rather than separate systems, while the shared support structures reduce overall system complexity compared to multiple independent turbine installations.
