Weighted Umbrella-Table Assembly for Wind Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbrella and table assemblies fail to effectively withstand wind forces due to lack of stabilization through combining the weight and size of the components, resulting in an unstable structure with a high center of gravity.
Innovation Solution
The design incorporates a tubular pole with a removable weight member and locking collar assemblies that combine the umbrella and table, lowering the center of gravity by securely attaching the components with complementary half-rings and bolts, creating a structurally stable and easy-to-assemble unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If umbrella and table assemblies are designed to withstand lateral and uplift forces, then stability is improved, but device complexity increases due to numerous parts and complicated installation
Solution Approach 1:
The patent combines the umbrella pole and table leg into a single integrated assembly, eliminating the need for separate securing mechanisms. The umbrella pole is directly inserted into and secured by the table leg structure, merging two components into one stable unit that resists lateral and uplift forces without requiring additional parts or complex installation procedures.
2Reliability
If umbrella and table assemblies are designed to withstand wind forces, then reliability is improved, but ease of manufacture deteriorates due to complicated features
Solution Approach 1:
The patent extracts and eliminates complicated securing features from the design, retaining only the essential integrated structure. By removing unnecessary parts and simplifying the connection between umbrella and table, the design achieves wind force resistance through the fundamental weight and size combination of the components, making manufacturing simpler and more economical.
3Stability of the object's composition
If umbrella and table assemblies are designed to withstand wind forces, then stability is improved, but ease of operation worsens due to complicated installation
Solution Approach 1:
The patent segments the assembly into simple, modular components that can be easily handled and installed. The umbrella pole and table leg are designed as separate but compatible segments that connect through a straightforward insertion and securing process, allowing for easy assembly and disassembly while maintaining stability during use.

AI summary
A table and umbrella assembly capable of withstanding lateral forces by providing an overall center of gravity below its top. Two collar lock assemblies are removably mounted to a pole assembly that passes through the top center. The umbrella pole assembly, when tubular, may include a weight introduced to the lowermost member. The weight may be either solid or liquid and does not extend above the top.
