Solution Overview
Problem
Current multi-slide panel systems with non-symmetrical interlock assemblies require more parts, additional assembly steps, and result in suboptimal thermal and sealing efficiency, increasing labor and material costs.
Innovation Solution
A symmetrical interlock assembly with a strut and frame member configuration that can be used on either side of a panel, featuring a strut extension and notch for panel retention, and a hybrid material combination for reduced thermal conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-symmetrical interlock system with two interlocks on different frame track planes is used, then the interlock can function on both interior and exterior sides, but more parts are required and additional assembly steps are needed
Solution Approach 1:
The patent applies asymmetry by designing the interlock assembly with a non-symmetrical strut configuration where the strut extension length differs on interior and exterior sides. This allows a single interlock design to function on both interior and exterior frame tracks without requiring mirrored versions, thereby reducing part variety while maintaining versatility.
Solution Approach 2:
The interlock assembly is designed to be universal by incorporating a strut with differentiated extension lengths that can accommodate both interior and exterior mounting configurations. The single interlock design serves multiple functions by adapting to different frame track plane requirements through its non-symmetrical geometry.
2Device complexity
If the interlock is made symmetric, then fewer parts and assembly steps are required, but the strut placement location becomes non-optimal
Solution Approach 1:
The patent deliberately employs asymmetry in the strut configuration, where the strut extension length on the interior side differs from the exterior side. This non-symmetrical design optimizes the strut placement location for structural effectiveness while maintaining a reduced part count through the use of a single interlock design for both interior and exterior applications.
3Strength
If a non-symmetrical interlock system is used, then the interlock can be optimized for specific placements, but thermal efficiency and sealing efficiency are reduced
Solution Approach 1:
The patent applies asymmetry to the strut configuration to optimize structural strength and strut placement, while the extended strut extension on the exterior side provides additional thermal insulation and sealing surfaces. This non-symmetrical design achieves both structural optimization and improved thermal efficiency by utilizing the extended strut to bridge gaps and reduce thermal bridging.
Solution Approach 2:
The interlock assembly utilizes composite construction combining the strut and frame member as integrated components with differentiated material properties. The strut provides structural strength and thermal insulation, while the frame member provides mounting functionality, creating a composite structure that optimizes both mechanical performance and thermal efficiency.

AI summary
An interlock assembly, comprising a strut having a strut extension, a frame member fixedly attached to the strut. An interlock assembly, additionally wherein the strut and the frame member extend longitudinally from a first end to a second end and are configured to retain an end of a panel member. Further a notch is formed through the strut and the frame member at one of the first end or the second end, wherein the notch is configured to receive a plate member of a connecting frame member, and wherein a first portion of the strut extension is to an interior side of the plate member and a second portion of the strut extension is to an exterior side of the plate member. Additionally, a sliding panel system is described that includes the interlock assembly.
