Umbrella Canopy Angle Adjustment via Swing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrellas have a fixed canopy angle, limiting their shading effect when sunlight or rain falls at an oblique angle, as the frame is securely mounted on an upright post and cannot be adjusted.
Innovation Solution
An umbrella with a swing mechanism and driving mechanism that allows the frame to pivot relative to the upright post, enabling the canopy to be adjusted by a user through a rocker arm, allowing the frame to tilt leftward or rightward for improved shading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the frame is securely mounted on the upright post, then the structural stability is improved, but the adaptability of the canopy angle deteriorates
Solution Approach 1:
The frame is transformed from a fixed static structure to a dynamic adjustable structure. The swing mechanism allows the frame to pivot between a horizontal position and an inclined position, enabling the canopy angle to adapt to different sunlight or rain directions while maintaining structural stability through controlled mechanical movement
2Stability of the object's composition
If the frame is fixed at a secure angle, then the structural stability is improved, but the ease of operation for angle adjustment deteriorates
Solution Approach 1:
The driving mechanism is designed to be operated by the user through simple manual input. The swing mechanism automatically translates the user's input motion into the desired frame angle adjustment, making the system self-adjusting without requiring complex control operations
3Adaptability or versatility
If a driving mechanism is added to enable angle adjustment, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The swing mechanism introduces dynamic adjustability to the previously static frame structure, allowing the canopy angle to change according to environmental conditions while maintaining a relatively simple mechanical implementation through pivoting and linkages
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and quick adjustment of the canopy's angle, providing a better shading effect by allowing the frame to tilt, thus accommodating varying angles of sunlight or rain, enhancing user convenience and effectiveness.
Implementation Method 1
a driven nut rotatably mounted in the housing and screwed onto the outer thread of the driven rod
Implementation Method 2
a driven gear rotatably mounted in the housing and secured on the driven nut to drive the driven nut to rotate relative to the driven rod, a drive gear meshing with the driven gear to drive the driven gear to rotate relative to the driven rod
Implementation Method 3
a rocker arm secured on the propeller shaft to rotate the propeller shaft
Implementation Method 4
a pivot seat pivotally mounted on the upright post

AI summary
A umbrella includes an upright post, a swing mechanism pivotally mounted on the upright post, a frame mounted on the swing mechanism to pivot in concert with the swing mechanism relative to the upright post, and a driving mechanism mounted on the upright post and connected with the swing mechanism to drive the swing mechanism to pivot relative to the upright post. Thus, the frame is rolled relative to the upright post to tilt leftward or rightward to adjust the inclined angle of the skeleton of the frame so as to provide a better shading effect.
