L-Shaped Foundation Connector with Integrated Insulation and Sealing
Solution Overview
Problem
Current wood-frame construction methods face inefficiencies due to insufficiently flexible rim boards, poor quality sill plates, and out-of-level or square foundations, leading to construction delays, material wastage, and energy losses through air infiltration and heat conduction.
Innovation Solution
A preassembled L-shaped connector system with a sill sealer, insulation panel, and subfloor gasket, designed to securely attach framing components to the foundation, ensuring planarity, reducing air infiltration, and enhancing thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional separate components (sill plate, rim board, anchors) are used for connecting framing to foundation, then flexibility in installation is maintained, but construction time increases and material quality varies
Solution Approach 1:
The patent combines multiple separate components (sill plate, rim board, anchors, and fasteners) into a single pre-assembled connector unit. This integration eliminates the need for separate installation of each component, directly addressing the contradiction by improving construction speed while managing complexity through pre-fabrication.
Solution Approach 2:
The connector is pre-assembled with anchors and fasteners attached before delivery to the construction site. This preliminary action ensures quality control and proper configuration is achieved during manufacturing rather than during field installation, resolving the contradiction between installation efficiency and component complexity.
2Ease of operation
If rigid rim boards are used for floor framing, then structural strength is maintained, but planarity adjustments become difficult and time-consuming
Solution Approach 1:
The connector design incorporates adjustable elements that allow for planarity corrections while maintaining structural integrity. The pre-assembled nature provides initial rigidity, while built-in adjustment capabilities enable field corrections without compromising strength, resolving the contradiction between ease of adjustment and structural strength.
3Reliability
If traditional sill sealing methods are used, then installation simplicity is maintained, but air-tight sealing between foundation and sill plate is insufficient
Solution Approach 1:
The air sealing function is integrated into the pre-assembled connector unit, combining the sill plate, sealing materials, and fastening elements into a single system. This integration improves air-tight sealing effectiveness while managing complexity through pre-configuration during manufacturing rather than field assembly.
4Manufacturing precision
If manual sorting and selection of sill plates is performed, then material quality control is achieved, but labor time and material wastage increase
Solution Approach 1:
Quality control and material selection are performed during the pre-assembly process at the manufacturing stage rather than during field installation. This preliminary action ensures consistent material quality while eliminating the time-consuming manual sorting that would otherwise be required on construction sites, directly addressing the contradiction between quality control and time loss.
5Manufacturing precision
If foundation imperfections (out of level or square) are corrected during sill plate installation, then structural accuracy is improved, but construction time and labor increase
Solution Approach 1:
The pre-assembled connector incorporates adjustable elements that enable correction of foundation imperfections (out of level or square conditions) while maintaining relatively efficient installation. The dynamic adjustment capabilities built into the connector allow for accuracy improvements without proportionally increasing installation time, addressing the contradiction between precision and productivity.
