Solution Overview
Problem
Vertical-axis wind power generators have low power generation capacity and low electricity output, and their large-scale deployment requires significant floor space and high construction costs due to the need for multiple tower tubes.
Innovation Solution

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 increases, but floor space requirements and construction costs increase significantly
Solution Approach 1:
The patent transitions from horizontal arrangement of multiple wind power generators to vertical stacking along the tower body's extending direction. This dimensional change allows multiple generators to occupy the same ground footprint while being arranged at different heights, thereby increasing power generation capacity without proportionally increasing floor space requirements
Solution Approach 2:
The patent implements a nested structure where multiple wind power generators are stacked within and along a single tower body. The generators are positioned at different vertical levels, with each generator nested within the overall tower structure, allowing multiple generation units to share common support infrastructure and occupy minimal ground area
2Productivity
If multiple vertical-axis wind power generators are deployed to increase power generation capacity, then electricity output increases, but construction costs increase due to multiple tower tubes
Solution Approach 1:
The patent merges multiple wind power generators into a single integrated tower body structure. Instead of constructing separate towers for each generator, the design combines multiple generation units along one tower, sharing common structural support, foundation, and installation infrastructure, thereby reducing overall construction costs while maintaining increased power generation capacity
Solution Approach 2:
The single tower body serves multiple functions: it provides structural support for multiple wind power generators simultaneously, acts as a common mounting platform, and eliminates the need for multiple separate tower structures. This multi-functional design reduces material requirements and construction complexity
3Area of stationary object
If vertical-axis wind power generators are stacked along the tower body, then floor space is reduced, but connection stability between generators must be ensured
Solution Approach 1:
The patent segments the connection system into multiple independent connecting members arranged in different spatial directions. Each connecting member provides support and stabilization in specific orientations, collectively ensuring the stability of stacked generators while allowing modular assembly and maintaining compact footprint
4Stability of the object's composition
If connecting members are arranged in different directions between generators, then connection stability is enhanced, but device complexity increases
Solution Approach 1:
The patent applies different connecting member configurations at different locations and orientations based on local stability requirements. Each connecting member is positioned and oriented to address specific structural needs at that location, providing targeted support while maintaining overall system stability without requiring uniform complex arrangements throughout
