Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular structures face thermal characteristic issues due to metal structural studs acting as thermal bridges, which complicates environmental control and increases costs, especially in applications like grow rooms or cleanrooms.
Innovation Solution
A structural stud post assembly with a thermal break, featuring a receiver section with a H-shaped central element and a thermal break assembly within the center bar, and a raceway section with a U-shaped cross-section, designed to fit snugly into channels of the receiver section, utilizing insulating structural polymers for thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal structural studs are used to transmit vertical loads, then structural strength is improved, but thermal insulation deteriorates due to thermal bridging
Solution Approach 1:
The structural stud is divided into multiple segments along its length, with insulating material placed between segments. This segmentation breaks the continuous thermal path while maintaining structural load-bearing capability through the metal portions.
Solution Approach 2:
An insulating material acts as an intermediary element between metal structural components. This intermediary reduces thermal conductivity while allowing the metal parts to maintain their structural function for load transmission.
2Loss of energy
If thermal break assembly is added to reduce thermal conductivity, then thermal insulation is improved, but device complexity increases
Solution Approach 1:
The insulating material is nested within or between the metal structural components. This nesting approach integrates the thermal break function into the existing structure without requiring separate external assemblies, thereby reducing overall complexity.
Solution Approach 2:
The structural support function and thermal insulation function are merged into a single integrated assembly. The metal components provide structural strength while the insulating material provides thermal break, combining multiple functions in one system.
3Loss of energy
If insulating material is placed within structural channels, then thermal insulation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The insulating material is placed specifically in localized regions where thermal bridging occurs, such as at joints or connections. This targeted approach provides thermal insulation where most needed without requiring precise insulation throughout the entire structure.
Solution Approach 2:
The design accommodates variations in manufacturing precision by using insulating materials that can be compressed or adjusted to fit within the structural channels. This flexibility in parameters allows for easier manufacturing while maintaining thermal insulation effectiveness.

AI summary
A structural stud post assembly comprising a center receiver section having opposing receiver channels.formed by side walls and angled flanges, and a pair of raceway inserts also defining a raceway channel for accepting wiring and equipment to be disposed in the raceway. The raceways can be installed in the receiver channels to accept and accommodate wiring and equipment The center receiver comprises a thermal break at about a midpoint to prevent there from being a metal-to-metal thermally conductive pathway through the stud. The structural stud post may be used in the construction of modular building systems.
