Pitched Roof Wind Generator with Hinged Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical generators are not specifically designed for installation on pitched roofs, lacking a hinge system for secure mounting and efficient wind energy utilization from any direction, and often require additional wind sources or are limited to specific roof types.
Innovation Solution
A wind-powered electrical generator with a housing suspended from a pitched roof's bottom surface, featuring vertically-oriented tracks and hinged brackets to ensure vertical orientation, allowing wind vanes to extend above the roof and rotate to produce electricity, while minimizing exposed components and maintaining roof integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the generator is mounted directly on the roof surface without a hinge system, then the installation is simpler, but the generator cannot maintain proper vertical orientation on pitched roofs and cannot adapt to varying roof pitches
Solution Approach 1:
The patent employs hinged brackets that can pivot and adjust to different angles, allowing the generator housing to maintain a vertical orientation regardless of the roof's pitch angle. This dynamic adjustment capability enables the system to adapt to varying roof pitches while keeping the generator properly oriented for optimal wind capture.
Solution Approach 2:
The mounting system is divided into separate components: a base bracket attached to the roof, a hinged connection joint, and the generator housing. This segmentation allows each component to perform its specific function independently, with the hinged joint providing the necessary degrees of freedom to accommodate different roof pitches while maintaining vertical orientation of the generator.
2Productivity
If the wind vanes are positioned above the roof surface, then wind energy capture is improved, but more components are exposed to the environment increasing maintenance requirements
Solution Approach 1:
The patent uses the roof structure itself as an intermediary protective element. The wind vanes extend through the roof surface, with the roof acting as a protective cover for the lower portions of the wind vanes and the generator housing. This reduces the amount of components exposed to harsh environmental conditions while still allowing sufficient wind exposure for effective energy capture.
3Shape
If the generator housing is suspended from the bottom surface of the roof, then the visual appearance is improved and roof integrity is maintained, but the mounting structure becomes more complex
Solution Approach 1:
The hinged suspension structure allows the generator housing to be mounted underneath the roof surface while maintaining the ability to adjust and secure at proper angles. The dynamic hinged connection provides both aesthetic benefits by hiding the generator beneath the roof and structural benefits by allowing proper orientation despite the inverted mounting position.
