Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible canopy frames face challenges in achieving a strong and stable foundation while minimizing weight and size, particularly for use in events like sporting events and festivals, where traditional designs may not provide the desired ease of use and versatility.
Innovation Solution
A collapsible canopy frame design featuring a plurality of side poles, edge scissor assemblies, and a hub rib pole system that allows for adjustable configurations between expanded and collapsed states, with telescoping side poles and a unique arrangement of scissor assemblies to support a canopy covering efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional collapsible canopy frame with a central support member and pyramidal shape is used, then structural stability is improved, but weight and size increase
Solution Approach 1:
The canopy frame is divided into multiple modular components including telescoping legs, scissor assemblies, and a canopy support assembly that can be independently collapsed and stored, reducing overall weight while maintaining stability when deployed
Solution Approach 2:
The frame incorporates telescoping legs with adjustable lengths and scissor assemblies that enable dynamic reconfiguration between expanded and collapsed states, allowing the structure to adapt its weight distribution and stability characteristics based on operational needs
2Stability of the object's composition
If a traditional collapsible canopy frame with a central support member and pyramidal shape is used, then structural stability is improved, but device complexity increases
Solution Approach 1:
The canopy support assembly merges the central support function with the canopy attachment mechanism into a single integrated unit that attaches to the telescoping legs, reducing the number of separate components and simplifying the overall frame structure while maintaining stability
Solution Approach 2:
The scissor assemblies serve multiple functions including providing structural support, enabling expansion and collapse mechanisms, and facilitating adjustment of canopy height, thereby reducing the need for additional specialized components
3Ease of operation
If the canopy frame is designed for easy collapse and expansion, then ease of operation is improved, but structural stability may deteriorate
Solution Approach 1:
The telescoping legs and scissor assemblies are designed with dynamic locking mechanisms that allow easy expansion and collapse during operation while automatically providing structural stability when in the deployed position, ensuring both ease of operation and stability are achieved
