Adjustable Umbrella Canopy Shade Retainer System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbrella canopy shades lack efficient mechanisms for adjusting the canopy's angle and position, leading to limited usability and stability, especially when used for extended periods.
Innovation Solution
An adjustable cantilever umbrella canopy shade with a retainer system that includes a mounting post, cantilever support, tension member, and a handle shaft retainer, allowing for height adjustment and secure positioning through a threaded handle shaft and guide members that engage with angled channels, providing stability and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the canopy angle is fixed, then the structure is simple and stable, but the usability is limited and cannot adapt to different sun positions
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the canopy to change its angle from a fixed position to multiple adjustable positions. The retainer system with movable retainer member enables the canopy to be positioned at different angles while maintaining structural stability, thus achieving adaptability without excessive complexity.
Solution Approach 2:
The adjustment mechanism is divided into separate functional components: the retainer system with retainer member, retainer channel, and engagement features. This segmentation allows each component to perform its specific function independently, simplifying the overall design while enabling angle adjustment capability.
2Ease of operation
If manual adjustment mechanisms are used, then the device complexity is reduced, but the operation requires more time and effort
Solution Approach 1:
The retainer member is pre-positioned within the retainer channel with engagement features that automatically align with the canopy structure. This preliminary arrangement allows for quick engagement and adjustment without requiring complex alignment procedures or excessive manual effort, reducing both time and effort required for operation.
3Reliability
If the canopy position is not securely retained, then the operation is simpler, but the stability deteriorates during use
Solution Approach 1:
The retainer system is designed to automatically engage and secure the canopy at the desired position through the interaction of the retainer member with the retainer channel and engagement features. Once positioned, the system self-locks without requiring additional fastening operations, maintaining both simplicity of operation and reliability of position retention.

AI summary
An adjustable umbrella canopy shade has a mounting post. The mounting post has a mounting post front side and a mounting post rear side. A cantilever support is mounted to the mounting post at a lower post hinge. A tension member is mounted to the mounting post at an upper post hinge. The tension member is mounted to the cantilever support at a cantilever support middle joint. A canopy is mounted to the cantilever support. A retainer system is mounted to the mounting post and coupled to the lower post hinge so that the retainer system moves with the lower post hinge. The lower post hinge is translationally mounted on the mounting post. A handle is formed on the retainer system, and the handle is mounted to a threaded handle shaft.
