Canopy Frame Eave Pole Retractable Shade Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional canopy frames do not effectively extend the area of shade when expanded, and they lack a mechanism to efficiently collapse and reconfigure for easy storage and transport.
Innovation Solution
The canopy frame incorporates an eave structure with a slidably connected eave pole that engages a support pole to lock in the expanded position and release for retraction during collapse, utilizing a combination of telescoping legs, scissor assemblies, and pivot connections to facilitate expansion and collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the canopy frame is expanded to increase shade area, then the area of shade is improved, but the volume and weight for storage increase
Solution Approach 1:
The canopy frame is divided into separate functional components: a collapsible support structure (legs and scissor assemblies) and an extendable eave pole. This segmentation allows the support structure to be collapsed for compact storage while the eave pole can be independently extended to maintain shade area when deployed.
Solution Approach 2:
The eave pole is designed to telescope within the roof pole structure, allowing the eave pole to be nested inside the roof pole during collapse for compact storage, and extended outward when deployed to increase shade area without proportionally increasing storage volume.
2Area of moving object
If the canopy frame is expanded to increase shade area, then the area of shade is improved, but the device complexity increases
Solution Approach 1:
The eave pole is designed with dynamic characteristics, allowing it to be fixed relative to the roof pole when the canopy is stationary to provide extended shade, and collapsible when the canopy is being transported or stored. This dynamic adaptability enables the structure to change its configuration based on operational requirements.
Solution Approach 2:
The eave pole mechanism is integrated with the existing roof pole structure through sliding and engaging connections. This merging of functions allows the eave extension capability to be added to the canopy frame without requiring a completely separate support structure, thereby reducing overall complexity.
3Area of moving object
If the eave pole is extended to increase shade area, then the area of shade is improved, but the structural integrity may be compromised
Solution Approach 1:
The eave pole is pre-configured with engagement features (such as tabs or lugs) that can lock into corresponding receptacles on the roof pole. This preliminary preparation ensures that when the eave pole is extended, it can be quickly and securely locked into position, maintaining structural integrity without requiring complex fastening mechanisms.

AI summary
A canopy has a frame with legs and scissor assemblies. Each leg has fixed and slidable brackets and the scissor assemblies are attached to brackets. The fixed bracket is connected to a roof pole and the slidable bracket is connected to a support pole which is connected to the roof pole. An eave pole is slidably connected with the roof pole and retracts and extends relative to the roof pole. The eave pole is configured to be engaged with the support pole when the frame is expanded. The eave pole is configured to be disengaged from the support pole when the frame is collapsed. The support pole is configured to be releasably locked with the eave pole with the eave pole extended and the frame expanded. The support pole is configured to be disengaged from the eave pole with the frame collapsed thereby allowing the eave pole to retract.
