Deck Pedestal with Threaded Shaft for Leveling Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevated building surface systems, such as decks and walkways, face challenges in providing adjustable and level support for building surface components, especially when dealing with uneven or varying surface conditions, as they often rely on fixed or limited adjustable pedestals that fail to accommodate the needs of heavy or large tiles effectively.
Innovation Solution
A support pedestal system featuring an adjustment apparatus with interconnected connectors and a shaft that allows for axial adjustment and tilting, enabling precise leveling and height adjustment of building surface components by threading mechanisms, ensuring stability and evenness across different surface conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed or limited adjustable pedestals are used, then the structure is simple, but the adaptability to uneven surfaces and heavy tiles is insufficient
Solution Approach 1:
The pedestal incorporates an adjustment mechanism with a shaft, first connector, and second connector that allows dynamic height adjustment. The shaft can rotate within the first connector while the second connector threads onto the shaft, enabling continuous height modification to adapt to uneven surfaces and accommodate heavy or large tiles effectively.
Solution Approach 2:
The adjustment mechanism uses a nested structure where the shaft is received within the first connector, and the second connector is threaded onto the shaft. This nested arrangement allows multiple adjustment components to be compactly integrated, providing adaptability without excessive structural complexity.
2Manufacturing precision
If adjustable connectors and shaft are used, then the adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The invention replaces complex mechanical leveling systems with a threaded adjustment mechanism. The second connector threads onto the shaft, converting rotational motion into precise linear height adjustment. This mechanical substitution provides accurate leveling capability while maintaining relatively simple component design and assembly.

AI summary
A method of fabricating a plate for a support pedestal used to support a building surface component above a fixed surface includes forming one or more ribs into a sheet of material adjacent a periphery of the sheet so that the rib extends substantially continuously about a central axis of the sheet that is perpendicular to first and second opposite surfaces of the sheet and creating a series of spacer tabs out of the sheet between the central axis and the rib that are configured to space adjacent building surface components placed over the sheet.
