Universal Subfloor Connector Joist Pile Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subfloor pile fixing systems require multiple dedicated components and fasteners for different interfaces, leading to frustration and inefficiency in construction, as builders need to navigate through various parts to find the correct components and may need to purchase new kits if one component is missing.
Innovation Solution
A connector system using a sheet metal plate with folded planar leaves, featuring distinct aperture patterns for secure attachment to both the pile and joist, allowing for a single connector type to be used across different interfaces, reducing inventory needs and simplifying construction by eliminating the need for multiple component types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple dedicated plates and fasteners are provided for different interfaces (pile-to-bearer and bearer-to-joist), then the connection performance and structural integrity are ensured, but the device complexity and inventory requirements increase significantly
Solution Approach 1:
The connector is designed as a universal component that can be used at both the pile-to-bearer interface and the bearer-to-joist interface. The single connector type replaces what previously required two different plate types (dedicated plates for each interface), reducing device complexity while maintaining reliable connections at all interfaces through standardized aperture patterns and fastener configurations
2Reliability
If multiple dedicated plates and fasteners are provided for different interfaces, then the connection performance is ensured, but the ease of operation deteriorates as builders must rummage through boxes of parts to find correct components
Solution Approach 1:
By providing a single universal connector type that works at all interfaces, the ease of operation is significantly improved. Builders no longer need to rummage through boxes of parts to find the correct plate type for each interface, as the same connector can be used consistently throughout the assembly process
3Reliability
If multiple dedicated plates and fasteners are provided for different interfaces, then the connection performance is ensured, but the loss of time increases due to potential need to acquire new kits if one component is missing
Solution Approach 1:
The universal connector eliminates the risk of missing components that would require acquiring new kits. With only one connector type needed for all interfaces, the construction process becomes more streamlined and time-efficient, as builders no longer need to check for the presence of multiple different plate types in their kits

AI summary
A connector to selectively connect joists and piles to a bearer of a sub floor support structure. The connector comprising of a sheet metal plate that is formed into an L shape to define two leaves. A leaf defining a first pattern of apertures and second leaf defines a second pattern of apertures that is different to said first pattern. Two of the connectors of the same shape and configuration can be used each at the joist to bearer interface and at the pile to bearer interface.
