Umbrella Pulley System Integrated Within Pole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pole umbrellas with pulley systems are often bulky and aesthetically unpleasing, lacking in compactness and functionality, as the pulleys are typically positioned externally, which can lead to a less elegant and less efficient mechanism for transitioning between closed and open configurations.
Innovation Solution
The integration of pulley systems within the interior circumference of the pole umbrella, featuring a compact and aesthetically pleasing design where upper pulleys are disposed substantially within the pole, allowing for a similar upper and lower hub assembly structure without external pulleys, and utilizing a rope system that adjusts length to facilitate smooth transitions between configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If pulleys are positioned externally on the pole, then the mechanism is simpler to manufacture, but the umbrella becomes bulky and aesthetically unpleasing
Solution Approach 1:
The upper pulleys are nested within the hollow top end portion of the pole, with pulleys positioned inside the interior circumference. This nesting approach allows the pulley system to be concealed within the pole structure, achieving a sleek aesthetic appearance while maintaining the functional mechanism for transitioning the umbrella between open and closed configurations
2Volume of moving object
If pulleys are disposed within the interior circumference of the pole, then the umbrella becomes more compact and aesthetically pleasing, but the mechanism becomes more complex
Solution Approach 1:
The pulley system transitions from an external two-dimensional arrangement on the pole surface to a three-dimensional configuration nested within the hollow top end portion. This dimensional change allows the pulleys to be positioned inside the pole structure, achieving compactness and aesthetic appeal while the rope system maintains the transition functionality through the pole's interior space
3Loss of substance
If upper pulleys are integrated within the pole, then material usage is reduced and aesthetics improve, but manufacturing precision requirements increase
Solution Approach 1:
The upper pulleys are nested within the hollow top end portion of the pole, utilizing the existing internal space rather than adding external components. This nesting approach reduces overall material usage while the pole's hollow structure provides a natural housing that simplifies positioning precision requirements compared to external mounting arrangements

AI summary
An umbrella includes a pole and upper pulley assembly, a lower hub assembly, and a rope. The pole has a base portion and a top end portion. The top end portion defines a through passage that extends entirely through the top end portion. The upper pulley assembly is disposed substantially within the through passage. The lower hub assembly is slidingly disposed about the pole such that the lower hub assembly has a first position in which the umbrella is in a closed configuration and a second position in which the umbrella is in an open configuration. The second position is above the first position. The rope extends through a lower pulley assembly and the upper pulley assembly. The rope is configured to translate the lower hub assembly from the first position to the second position and to maintain the lower hub assembly in the second position.
