Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prefabricated structural panels face issues with thermal bridging, structural integrity, and water resistance, leading to increased costs and complexity in construction, as well as challenges in servicing and meeting building codes and personal preferences.
Innovation Solution
A building panel assembly comprising a load-bearing layer, a thermal insulating layer, and an optional fire-retarding layer, with integrated framing members that include passageways for conduits, and a method for fabricating these panels using laminated lumber and finger-jointing techniques to enhance structural integrity and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If internal or external support members are added to prefabricated structural panels, then structural integrity is improved, but thermal bridging increases and construction complexity increases
Solution Approach 1:
A thermal break layer is introduced as an intermediary between the internal support members and the panel surfaces. This thermal break layer has low thermal conductivity, interrupting the heat flow path through the support members while still allowing them to provide structural support. This resolves the contradiction by maintaining structural integrity through the support members while preventing thermal bridging through the thermal break layer.
2Reliability
If multiple layers are added after core structure erection, then insulation and fire resistance are improved, but construction time and labor requirements increase
Solution Approach 1:
Multiple functional layers (structural panel, thermal insulation layer, and fire-resistant layer) are merged into a single integrated prefabricated unit before delivery to the construction site. This allows all layers to be installed simultaneously as one component, eliminating the need for sequential installation of multiple separate layers, thereby reducing construction time and labor requirements while maintaining all necessary functions.
3Ease of operation
If conventional construction methods are used, then ease of servicing is maintained, but construction costs and time increase
Solution Approach 1:
Conduits for electrical, plumbing, and HVAC systems are pre-installed within the integrated panel structure during manufacturing, before the panel reaches the construction site. This preliminary action eliminates the need for later intrusive servicing work that would otherwise require dismantling or cutting into the panel, thereby maintaining ease of servicing while dramatically improving construction efficiency by reducing on-site labor and time.

AI summary
A building panel assembly is disclosed. The building panel assembly consists of a first layer having one or more laminated softwood or hardwood lumber coupled to each other using finger-joints. Further, a second layer is attached to the first layer, and acts as a thermal insulation for the building panel. Further, an optional third layer is attached to the second layer, and acts as a fire retarding layer for the building panel. Further, one or more framing members are coupled to the second layer and optionally to the third layer, and transversely spaced from each other. The one or more framing members have transversely oriented passageways for passage of wires and pipes.
