Wall Panel Window Mounting via Edge Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for mounting windows in modular building units are complex and time-consuming, often requiring windows to be clamped between inner and outer wall panel faces, which limits panel thickness and can cause thermal bridging.
Innovation Solution
A wall panel assembly with connecting members that extend along the opening edges of the panel, allowing window assemblies to be mounted internally, reducing thermal bridging by spacing these members from the panel faces and using insulating material to support both the panels and the connecting members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If windows are clamped between inner and outer wall panel faces, then window mounting is achieved, but wall panel thickness is limited
Solution Approach 1:
The patent transitions from a traditional between-face mounting approach to an edge-face mounting approach. Connecting members are attached to the edge faces of the wall panel opening rather than clamping between inner and outer faces, effectively changing the mounting dimension from thickness-direction to edge-direction, thereby enabling window mounting regardless of panel thickness.
Solution Approach 2:
The wall panel assembly is segmented into distinct functional components: the wall panel members, insulating material, connecting members, and window assembly. The connecting members are separate detachable components that bridge the gap between the opening edge faces and the window assembly, allowing independent optimization of each component's thickness and dimensions.
2Ease of operation
If traditional mounting methods are used, then window installation is achieved, but installation time increases
Solution Approach 1:
The connecting members are pre-attached to the edge faces of the wall panel opening during panel manufacturing or pre-assembly. This preliminary action eliminates the need for complex on-site mounting operations, allowing the window assembly to be quickly installed by simply attaching it to the pre-positioned connecting members, significantly reducing installation time.
Solution Approach 2:
Connecting members serve as intermediary components that simplify the mounting process. Instead of directly clamping the window between thick wall panels or performing complex on-site fabrication, the connecting members act as standardized interface elements that mediate between the wall panel opening and the window assembly, enabling quick and easy installation.
3Strength
If connecting members are placed close to wall panel members, then structural support is improved, but thermal bridging increases
Solution Approach 1:
Insulating material is introduced as an intermediary substance between the connecting members and the wall panel members. This insulating layer maintains the structural connection while thermally isolating the metal connecting members from the wall panel members, preventing thermal bridging and reducing energy loss through the wall assembly.
Solution Approach 2:
The wall panel assembly employs different material properties in different locations: metal connecting members provide structural strength at connection points, while insulating material provides thermal resistance at the interface between connecting members and wall panels. This local differentiation of material qualities allows simultaneous optimization of both structural support and thermal performance.

Function Achieved in This Case
Facilitates faster window installation and reduces thermal bridging by allowing window mounting regardless of panel thickness and using insulating material to minimize heat transfer between panel members.
Implementation Method 1
The wall panel may comprise an insulating material extending between the first and second wall panel members, such that said insulating material defines the opening edge faces

AI summary
A wall panel assembly is provided for a modular building unit. The wall panel assembly is formed from a wall panel with inner and outer wall panel members and defining an opening therethrough for a window assembly therein. The opening defines a plurality of opening edge faces extending around said opening, and at least one connecting member extends at least partially along each opening edge face and defines a substantially planar upper mounting surface at least partially covering the respective opening edge face for mounting a window assembly thereon.
