Modulating Thatch Shade Structure Wind Uplift Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thatch shade structures are prone to wind damage, particularly in extreme climate conditions, leading to structural integrity loss or failure due to unsustainable wind uplift.
Innovation Solution
A wind damage resistant modulating thatch shade structure is designed with a frame coupled to a post, featuring a plurality of longitudinal rods and pivotally attached thatch shingles. This configuration allows wind to pass through by modulating the thatch shingles, reducing wind uplift pressures and enhancing structural resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thatch shade structures are used to provide shade and ambiance, then aesthetic function is achieved, but structural integrity is compromised under strong wind conditions
Solution Approach 1:
The thatch shingles are designed to be movable rather than fixed, allowing them to dynamically adjust their position in response to wind forces. The shingles can rotate or shift along the support members, enabling the structure to adapt to varying wind conditions and reduce wind uplift pressures that would otherwise compromise structural integrity.
Solution Approach 2:
The structure changes the physical state or configuration of the thatch shingles under wind load. When wind pressure increases, the shingles transition from a fixed covering to a more open configuration with increased spacing, effectively changing the permeability parameter of the structure to allow wind passage and reduce uplift forces.
2Illumination intensity
If solid thatch shingles are used to block sunlight, then shading function is achieved, but wind uplift pressure increases causing structural failure
Solution Approach 1:
The thatch shingle structure functions as a porous system where the individual shingles create gaps and channels that allow wind to pass through. This porous configuration reduces the surface area exposed to wind pressure and enables wind flow through the structure, significantly reducing wind uplift pressures while still providing adequate sunlight blocking when in the closed position.
Solution Approach 2:
The design converts the harmful effect of wind pressure into a beneficial mechanism by allowing wind to interact with the movable shingles. The wind force that would normally cause uplift damage instead triggers the shingles to open and create passage ways, transforming the harmful wind pressure into a self-regulating mechanism that protects the structure.
3Stability of the object's composition
If fixed thatch shingles are attached to the frame, then structural stability is improved, but wind damage resistance is reduced
Solution Approach 1:
The attachment system transitions from a fixed connection to a dynamic, movable connection. The thatch shingles are attached to longitudinal members that allow rotation or sliding movement, enabling the shingles to adjust their position dynamically in response to wind loads while remaining structurally integrated with the frame.
Solution Approach 2:
The thatch shingle system is divided into discrete, independently movable units rather than a continuous fixed covering. Each shingle can move independently along its support member, allowing localized adjustment to wind forces while maintaining overall structural stability through the segmented design.
