Repositionable Canopy Design for Wind-Resistant Team Shelters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional team shelters are prone to wind-induced tip-overs due to their fully enclosed design, leading to potential damage and costly repairs.
Innovation Solution
A repositionable canopy system that allows the shelter's canopy to be adjusted between a raised and lowered position, reducing wind resistance and preventing tip-overs by altering the aerodynamic profile and creating openings at the bottom for increased air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the canopy is positioned in a raised orientation to allow access and provide protection, then the shelter provides effective protection from elements and access to bench, but the shelter becomes more susceptible to wind-induced tip-overs
Solution Approach 1:
The canopy is made dynamically repositionable between a raised orientation (for protection and access) and a lowered orientation (for wind resistance). This dynamic adjustment allows the shelter to adapt to different operational conditions, providing protection when needed while minimizing wind exposure during high wind conditions.
Solution Approach 2:
The position parameter of the canopy is changed between two distinct states: raised (providing protection) and lowered (reducing wind resistance). By changing this geometric parameter, the shelter's aerodynamic profile is modified to reduce susceptibility to tip-overs while maintaining protective function when required.
2Stability of the object's composition
If the canopy is lowered to reduce wind resistance, then the shelter becomes less susceptible to tip-overs, but access to the bench is blocked
Solution Approach 1:
The canopy's dynamic repositioning capability allows it to be lowered to a second orientation that blocks access to the bench. This dynamic state change enables the shelter to prioritize stability during high wind conditions, accepting temporary loss of access as a trade-off for preventing tip-overs and potential damage.
3Adaptability or versatility
If the canopy is made repositionable to adjust between protection and wind resistance, then the shelter's adaptability to different conditions improves, but the device complexity increases
Solution Approach 1:
The canopy is designed with dynamic repositioning capability through a mechanism that allows transition between raised and lowered orientations. This dynamic feature enhances adaptability to different weather conditions while introducing mechanical complexity to the shelter structure.
Solution Approach 2:
The repositionable canopy mechanism serves multiple functions: providing protection from elements in the raised position, reducing wind resistance in the lowered position, and potentially providing structural support or additional protection when positioned at different angles. This multi-functionality justifies the added complexity by delivering diverse protective capabilities.

AI summary
Methods for using a shelter such as a team shelter includes, for example, positioning a canopy of the shelter in a raised position to provide a front facing opening under the canopy in the shelter, and moving the canopy of the shelter to a lowered position to reduce the size of the front facing opening.
