Outdoor Shading Device with Detachable Pole and Arc Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canopies supported by ropes occupy a large area and pose a tripping hazard, making them inconvenient to transport and negatively impacting user experience in crowded outdoor areas.
Innovation Solution
A sun shade cloth connected to a supporting pole formed by multiple connecting rods, with a through hole allowing the pole to pass through, and a fixing band to secure the cloth to the pole, eliminating the need for ropes and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ropes are used to pull and fix the canopy, then the canopy can be supported and stabilized, but the canopy occupies a large area and people easily trip over the ropes
Solution Approach 1:
The patent removes the ropes from the system entirely, extracting the harmful element that caused tripping hazards. Instead of using ropes to pull and fix the canopy corners, the invention uses a single central supporting pole that provides stability without extending ropes across the ground area.
Solution Approach 2:
The patent introduces a central supporting pole as an intermediary element between the ground and the canopy. This pole serves as a mediator that provides the necessary support and stability function previously achieved by ropes, but without the harmful side effect of creating tripping hazards across the canopy area.
2Temperature
If long poles are used to support the canopy to a certain height, then the canopy can be elevated for shading, but the canopy becomes inconvenient to carry and transport
Solution Approach 1:
The patent divides the long supporting pole into multiple shorter connecting rod segments. These segments can be easily assembled and disassembled, making the structure portable and easy to transport while still achieving the required height for effective shading when assembled.
Solution Approach 2:
The patent employs a dynamic assembly structure where the connecting rods can be joined together to form the full-length supporting pole during use, and separated for transport. This dynamic configuration allows the structure to adapt between its extended functional state for shading and its compact stored state for portability.
3Ease of operation
If multiple connecting rods are used to form the supporting pole, then the pole becomes easier to assemble and transport, but the structure becomes more complex
Solution Approach 1:
The supporting pole is divided into multiple connecting rod segments that can be easily assembled through simple connection mechanisms. The segmentation allows for compact storage and transport while maintaining structural integrity when assembled, balancing portability with structural simplicity.

AI summary
An outdoor shading device, including a piece of sun shade cloth (1) and a supporting pole (2). The supporting pole includes a plurality of connecting rods (20) connected end to end. Two adjacent connecting rods are detachably connected to each other. The connecting rods are tough. One side of the sun shade cloth is provided with a through hole (11). One end of the supporting pole passes through the through hole. During use, the supporting pole is bent to form an arc. Under the action of wind, the sun shade cloth can be blown up. Therefore, the sun shade cloth can cooperate with the supporting pole to form a shading space, which plays a sunshading role.
