Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertical-axis wind power generators suffer from low power generation capacity and low electricity output, with current solutions increasing floor space and construction costs due to the need for multiple machines and extensive tower structures.
Innovation Solution
A wind power generation apparatus with at least two wind power generators stacked along a tower body, sharing a single tower, where the rotation shafts are parallel to the tower's direction, and connected by multiple connecting members to enhance stability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple vertical-axis wind power generators are deployed to increase power generation capacity, then electricity output is improved, but floor space and construction costs increase
Solution Approach 1:
The patent transitions from horizontal deployment of multiple wind generators to vertical stacking along a single tower body. By arranging wind power generators in the vertical dimension rather than spreading them horizontally, the system achieves increased power generation capacity while minimizing floor space occupation. This dimensional transformation allows multiple generators to be stacked one above another on a shared tower structure.
Solution Approach 2:
The patent combines multiple wind power generators and a single tower body into an integrated system. Instead of each generator requiring its own separate tower and foundation, multiple generators share a common tower body, connecting members, and support structure. This merging reduces the total amount of construction materials needed and decreases both floor space requirements and construction costs.
2Reliability
If multiple separate tower structures are used for multiple wind power generators, then each generator has structural stability, but construction costs and material usage increase
Solution Approach 1:
The patent merges multiple tower structures into a single shared tower body that supports multiple wind power generators. The tower body, connecting members, and support structures are shared resources among all generators in the stack. This consolidation maintains structural stability through the rigid connection system while significantly reducing construction costs and material usage compared to providing separate towers for each generator.
Solution Approach 2:
The single tower body and its associated support structures serve multiple functions simultaneously - supporting multiple wind power generators, providing structural stability for the entire system, and reducing construction complexity. The connecting members and support structures are universal components that serve all generators in the stack rather than being dedicated to individual units.
3Area of stationary object
If wind power generators are stacked vertically to reduce floor space, then land usage efficiency is improved, but connection stability between generators may deteriorate
Solution Approach 1:
The patent segments the connection system into distinct functional components: connecting members that attach generators to the tower body, and support structures that provide lateral stability. This segmentation allows each component to be optimized for its specific function while working together to ensure overall connection stability. The modular connection system maintains stability despite the vertical stacking configuration.
Solution Approach 2:
The patent addresses connection stability in the vertical stacking configuration by introducing support structures that extend in directions perpendicular to the tower body's longitudinal axis. These support structures provide lateral bracing and rotational stability, compensating for the potential instability introduced by vertical arrangement. The connection system is designed to resist forces in multiple dimensions, ensuring stability despite the generators being stacked vertically rather than arranged horizontally.
