Raft Shading System with Segmented Frame and Telescoping Uprights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shading devices for rafts and small boats are cumbersome to store, unstable in wind, and require complex erection processes, lacking a balance between providing a large area of protection and ease of use.
Innovation Solution
A removable and storable shading system featuring a frame member with knuckles that securely attach to objects, telescoping uprights, and a fabric shade member with grommets, allowing for easy setup and stowage without interfering with the raft or boat's operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a bimini top is used to provide a large area of protection, then the protection area is increased, but the storage becomes cumbersome
Solution Approach 1:
The shading system is divided into multiple independent frame members (first frame member, second frame member, third frame member, fourth frame member) that can be separately assembled and disassembled. Each frame member connects to the raft independently, allowing the structure to be broken down into manageable segments for easy storage while maintaining a large coverage area when assembled.
2Device complexity
If a centrally supported umbrella is used, then the structure is simplified, but it becomes unstable in wind
Solution Approach 1:
The system uses four frame members positioned at different locations around the raft rather than a single central support. This asymmetric distribution of support points around the perimeter provides balanced stability in all directions, preventing the structure from toppling in wind while maintaining relative simplicity compared to complex cable systems.
3Area of stationary object
If an umbrella supported from above by cables, locks, and hinges is used to provide a large area of protection, then the protection area is increased, but the erection process becomes complex
Solution Approach 1:
The frame members are designed with telescoping sections that can be easily extended and locked into place, and the shade member can be adjusted to different positions. This dynamic design allows for quick assembly and adjustment without requiring complex static structures like multiple locks and hinges, while still providing a large coverage area.
