Adjustable Umbrella Rotation Base With Retractable Transport Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor umbrellas are cumbersome and inconvenient to move due to their weight, especially when stabilized with heavy objects like water or sand, and the addition of wheels for mobility can cause unintended movement when the umbrella is meant to be stationary.
Innovation Solution
An adjustable rotation base with a transportation arrangement that allows the umbrella to switch between a stationary mode and a transportation mode by lifting wheels up when not in use, enabling easy movement without compromising stability or aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are installed on the outdoor umbrella base, then mobility is improved, but unintended movement occurs when the umbrella is meant to be stationary
Solution Approach 1:
The base incorporates wheels that can be dynamically deployed or retracted based on operational mode. During transportation, wheels are extended to provide mobility. When the umbrella is set up for use, the wheels are retracted into the base housing, transforming the base from a mobile platform to a stable, stationary structure. This dynamic configuration allows the same base to satisfy both mobility and stability requirements at different times.
2Stability of the object's composition
If the supporting base is filled with water or sand to prevent toppling, then stability is improved, but the weight increases making the umbrella difficult to move
Solution Approach 1:
The base utilizes deployable wheels that transform the weight distribution and mobility characteristics. When wheels are retracted during use, the filled base provides maximum stability. When transportation is needed, the wheels are deployed to enable movement, and the base can be tilted or adjusted during transport to manage the weight of the water or sand filling.
3Stability of the object's composition
If the outdoor umbrella is designed to be stationary for prolonged use, then stability is improved, but mobility is reduced
Solution Approach 1:
The base is designed with a dual-state capability through deployable wheels. In the stationary state, wheels are retracted and the base is filled with water or sand to maximize stability for prolonged use. In the mobile state, wheels are deployed to facilitate transportation. This dynamic design allows seamless transition between stationary and mobile modes, satisfying both stability and mobility requirements.

AI summary
An adjustable rotation base includes a base housing and a transportation arrangement. The base housing has a bottom side, an upper side for coupling with the supporting post to support the outer umbrella in an upright manner, and a receiving cavity indently formed on the bottom side of the base housing, wherein the base housing includes a stationary unit provided at the bottom side for sitting on the ground surface in a stationary manner, and a plurality of transferring wheels rotatably supported at the bottom side of the base housing. The transportation arrangement is provided at the base housing to operate the base housing between an idle mode and a transportation mode in which the stationary unit is upwardly lifted to allow the transferring wheels being sitting on the ground surface, such that the base housing is adapted to be transported on the ground surface via the transferring wheels.
