Cladding System with Abutting Blocks for Weather Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cladding systems for building walls are complex, expensive, and difficult to install, often compromising weather resistance and thermal insulation due to their complexity and the need for adjustable brackets and separate thermally-insulating materials.
Innovation Solution
A cladding system comprising building blocks with engagement means that allow adjacent blocks to abut, creating a continuous waterproof and thermally-insulating barrier, reducing the need for load-transferring facings and simplifying installation by using lightweight, thermally-insulating block bodies and cementitious facings, with support brackets that align blocks without visible connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brackets or rails are used to attach cladding panels to the inner wall, then the cladding system provides structural support and coverage, but the system becomes complex, expensive, and difficult to install with compromised weather resistance and thermal insulation
Solution Approach 1:
The building block merges multiple functions into a single integrated component: the block body provides structural support and engagement with support brackets, the facing provides weather resistance and aesthetics, and the block itself provides thermal insulation. This eliminates the need for separate brackets, panels, and insulation layers, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The building block serves multiple purposes simultaneously: it acts as a structural support element, a weather-resistant cladding panel, a thermal insulation barrier, and a decorative facing. This multi-functionality resolves the contradiction by providing all necessary functions through a single component rather than a complex assembly.
2Adaptability or versatility
If adjustable brackets are used to allow proper alignment of panels, then the cladding system achieves proper installation flexibility, but the system becomes more complex and increases assembly time
Solution Approach 1:
The building block's engagement means are designed to automatically align and self-position on the support brackets without requiring adjustable mechanisms. The block's geometry and engagement features provide inherent alignment capability, eliminating the need for complex adjustable brackets while maintaining installation flexibility.
3Shape
If secret fixing is used to hide connection parts, then the aesthetic appearance is improved, but the installation becomes even more complex and maintenance becomes difficult
Solution Approach 1:
The connection mechanism is extracted and integrated into the building block itself through the engagement means between the block body and support brackets. The connection is concealed within the block structure rather than requiring separate hidden fixing mechanisms, achieving aesthetic appearance without compromising installation ease.
4Loss of energy
If thermally-insulating material is added in a separate step, then the thermal insulation performance is improved, but the assembly time and complexity increase
Solution Approach 1:
The thermal insulation function is merged into the building block by making the block body itself from thermally-insulating material. This eliminates the need for separate insulation installation steps, reducing assembly time while maintaining or improving thermal insulation performance.
5Ease of operation
If lightweight block bodies are used, then the installation ease and handling are improved, but the structural strength may be compromised
Solution Approach 1:
The building block uses composite construction with a lightweight thermally-insulating block body combined with a cementitious facing that provides structural strength and durability. This composite structure achieves both lightweight handling and sufficient strength for cladding applications.

Implementation Method 1
The body is shaped to engage with the material of a facing in such a manner as to guard against relative movement of the facing with respect to the body in any direction
Implementation Method 2
the bodies of blocks in adjoining horizontal rows abut one another, at least in part, the bodies of the blocks in the cladding system of the present invention provide a substantially continuous thermally insulating and water-proof barrier
Implementation Method 3
at least a part of the body of each block abuts at least a part of the body of a neighbouring block in an adjoining row so as to guard against water penetration between the rows
