Folding Chair Canopy Mount With Dual-Axis Adjustable Shading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding chairs with canopies or umbrellas often limit foldability and provide little adjustability for sun or rain protection, as they are either non-detachable or lack flexibility in positioning.
Innovation Solution
A detachable canopy or umbrella with push button hinges allowing 360-degree rotation and pivotal movement about horizontal axes, enabling adjustable positioning on either side of the chair for optimal protection from the sun and rain, while being easily stowed away for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a canopy or umbrella is attached to the chair, then sun and rain protection is provided, but the chair's foldability is limited or the canopy must be removed before folding
Solution Approach 1:
The canopy support system is segmented into detachable components including a post, arm, and mounting brackets that can be easily separated from the chair frame. This allows the canopy to be attached when needed for protection and detached when the chair needs to be folded or stored, resolving the conflict between protection and foldability.
Solution Approach 2:
The canopy mounting system transitions from static fixed attachment to dynamic detachable attachment. The quick-connect/m quick-release mechanism enables the canopy to be easily attached and detached, allowing the system to adapt between providing protection and allowing chair folding based on user needs.
2Stability of the object's composition
If a symmetrical canopy is mounted using centered or opposite side support arms, then structural stability is achieved, but adjustability for optimal protection is limited
Solution Approach 1:
The mounting system provides asymmetrical positioning capability, allowing the canopy to be mounted on either the left or right side of the chair depending on the desired protection direction. This asymmetrical flexibility enables optimal positioning for different sun and rain conditions while maintaining structural stability through the robust post-and-arm support configuration.
Solution Approach 2:
The canopy positioning system transitions from fixed symmetrical mounting to dynamic adjustable mounting. The ability to mount on either side and adjust the angle of the arm relative to the post allows the canopy to adapt its position for optimal protection while maintaining structural integrity through the stable triangular support geometry.
3Ease of operation
If the canopy is detachably mounted, then ease of attachment and detachment is improved, but reliability of connection may be compromised
Solution Approach 1:
The connection system is segmented into distinct mounting components (post, arm, brackets) with standardized quick-connect interfaces. This segmentation enables easy attachment and detachment while maintaining reliable connection through the robust mechanical interface designed to securely join the components during use.

AI summary
A folding canopy chair includes a frame, a seat, a back, and arm rests. An umbrella is secured to the frame and is pivotal between an upright use position extending above the chair and a downward storage position adjacent the frame. The umbrella is pivotal about both a horizontal axis and a vertical axis for selective positioning of the umbrella relative to the chair, so as to shade a person sitting in the chair from the sun. The umbrella may be non-symmetrical, and removably mounted on either the left or right side of the chair.
