Umbrella Holder Ring Clamp Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbrella holders installed through a centralized hole in patio tables often experience instability, leading to tilting, rotating, or collapsing due to poor contact between the umbrella and the table.
Innovation Solution
A cylindrical umbrella holder with a ring clamp at the upper end and adjustable slot, along with apertures and fasteners for secure attachment to vertical structures, provides enhanced stability by allowing independent adjustment and secure mounting of the umbrella.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an umbrella is installed through a centralized hole in a patio table, then installation is simple, but stability deteriorates leading to tilting, rotating or collapsing
Solution Approach 1:
The umbrella holder is divided into multiple functional components: a cylindrical body for insertion, a ring clamp for securing the umbrella shaft, and multiple fasteners for attachment to the table. This segmentation allows each component to perform its specific function optimally while maintaining overall stability.
Solution Approach 2:
The invention transitions from a simple single-hole insertion to a multi-point attachment system. The ring clamp provides circumferential contact with the umbrella shaft, while fasteners attach to multiple holes in the table surface, adding dimensional stability and preventing tilting and rotation.
2Device complexity
If a simple hole installation method is used, then device complexity is low, but reliability deteriorates due to poor contact between umbrella and table
Solution Approach 1:
The cylindrical holder body acts as an intermediary between the table surface and the umbrella shaft. It provides a structured interface that distributes loads and ensures proper alignment, while the ring clamp serves as another intermediary to secure the umbrella shaft firmly within the holder.
Solution Approach 2:
The holder design incorporates multiple holes in the cylindrical body that can accommodate different fastener configurations. This universal design allows the same holder structure to be reliably installed on various table types and configurations while maintaining consistent performance.

AI summary
An improved umbrella holder. The improved umbrella member has a cylindrical member with an upper end and a bottom end. The upper end has a pair of arms extending from the rear surface of the cylindrical member to form a ring clamp. The ring clamp can be tightened to secure an umbrella inside of the cylindrical member. A slot is defined between the ring clamp and the cylindrical member to allow adjustment of the ring clamp independently from the cylindrical member.
