Solution Overview

Problem

Conventional façade systems in buildings face challenges in achieving optimal thermal performance, acoustic isolation, and fire safety while allowing for automated manufacturing and rapid installation, particularly in multi-storey structures where heat transfer through solid wall elements is significant and manual assembly is often required.

Innovation Solution

A modular wall system incorporating a stud assembly with perforated quadrilateral plates that lengthen and narrow the heat path, combined with a wall protrusion bracket apparatus and insulation layers, enabling efficient thermal performance, automated manufacturing, and integration with concrete slabs for enhanced anchorage, while allowing for up to 60% glazing and accommodating various load transfer methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If solid plates are used in wall construction, then structural strength is improved, but heat transfer increases

Engineering Contradiction:
Improvestructural strengthVSAvoidheat transfer
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent applies perforated plates with holes arranged in specific patterns (e.g., staggered, interlocking) that create thermal resistance paths. The porous structure reduces heat transfer by disrupting continuous thermal conduction paths while maintaining structural integrity through the perforated geometry and material distribution.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The invention introduces a dimensional approach by arranging perforations in multi-level patterns (e.g., alternating rows offset from each other) rather than simple linear arrangements. This creates three-dimensional thermal resistance paths that lengthen and complicate heat transfer routes, significantly reducing thermal conductivity while preserving structural strength.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Extent of automation

If modular stud assemblies are used, then automated manufacturing is enabled, but assembly complexity increases

Engineering Contradiction:
Improveautomated manufacturingVSAvoidassembly complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The wall system is divided into modular stud assemblies that can be pre-manufactured and then assembled on-site. Each stud assembly is a self-contained unit with standardized components, enabling automated manufacturing while simplifying field installation through straightforward connection mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stud assemblies are designed as universal modules that can accommodate various wall configurations, insulation types, and cladding systems. The standardized interface and multi-functional design reduce assembly complexity by allowing the same basic component to serve multiple purposes across different application scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of energy

If perforated plates are used, then thermal performance is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveheat transfer reductionVSAvoidperforation precision
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The patent optimizes perforation parameters (hole diameter, spacing, pattern, and distribution) to achieve the desired thermal performance within manufacturing tolerances. By carefully selecting and standardizing these parameters, the design achieves effective heat transfer reduction while remaining compatible with conventional manufacturing capabilities.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention relates to a stud assembly for passing through a cavity wall, said stud assembly comprising: a quadrilateral plate comprising perforations, said plate comprising two opposing faces and four edges; an internal angle (13) for attaching to a first edge of the plate and also for attaching to an internal portion of a wall; an external angle (14) for attaching to a second edge of the plate and also for attaching to an external portion of the cavity wall; wherein the first edge and the second edge correspond to opposite edges of the quadrilateral plate. The stud assembly is prismatic and designed to be capable of being located by a robot and welded together by a robot. Therefore, the stud assembly may form a wall system suitable for automated manufacture.
