Collapsible Chair Canopy Frame for Adjustable Shade Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor furniture canopies lack versatility in positioning, as they are typically fixed in either an overhead or behind-the-furniture configuration, failing to provide adequate shade in intermediate positions and are cumbersome to store or carry.
Innovation Solution
A frame and canopy system that can be oriented in overhead, behind, or intermediate positions, with a collapsible and hinged design allowing for easy reconfiguration and storage, using connectors and pivot mechanisms to secure the canopy segments and support arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the canopy is fixed in overhead or behind-the-furniture configuration, then the structure is simple and stable, but the positioning versatility is limited and intermediate positions cannot be achieved
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed canopy structure into a movable one. The support arms are designed with pivot connections at multiple points (front end pivotally connected to chair front leg, rear end pivotally connected to chair back leg), enabling the canopy to dynamically adjust between overhead, behind, and intermediate positions. This dynamic configuration resolves the contradiction by providing positioning versatility while maintaining structural simplicity through standardized pivot mechanisms.
2Ease of operation
If the canopy is fixed in a rigid configuration, then the structural stability is high, but the ease of storage and carrying is poor
Solution Approach 1:
The patent applies segmentation by dividing the canopy into modular components: the canopy fabric, support arms, connectors, and chair structure. This segmentation allows each component to be independently positioned and reconfigured. The support arms can be detached from the chair legs, and the canopy can be removed from the support arms, enabling easy storage and transport while maintaining structural stability when assembled through standardized connection points.
3Ease of operation
If the canopy uses a collapsible and hinged design, then the ease of reconfiguration and storage is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple functions into unified components. The support arms serve dual purposes: they provide structural support for the canopy and simultaneously act as adjustment mechanisms through their pivotal connections. The connectors integrate both attachment and positioning functions, allowing the canopy to be easily reconfigured between overhead, behind, and intermediate positions without requiring separate adjustment mechanisms, thus reducing overall device complexity.

AI summary
An exemplary embodiment providing one or more improvements includes a frame which attaches to outdoor furniture, in particular to a chair, and a canopy. Embodiments can be moved from an overhead position to a behind the chair position. The frames can be moved from a collapsed to a fully extended position. In embodiments the canopy can be positioned to contain the collapsed frame and chair in the carrying position.
