Adhesive-Bonded Brick Cladding for Retrofit Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adding an additional brick wall layer to existing buildings for improved thermal insulation and weather protection are time-consuming, labor-intensive, and costly, particularly challenging around larger window openings due to the need for complex support structures.
Innovation Solution
A method involving gluing large, thermally insulating bricks directly to the existing wall without additional support elements like brackets or foundations, using a plaster layer to level the surface and enhance adhesion, allowing for a stable and efficient additional brick wall layer on either side of the existing wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional brick wall layer is built directly onto the existing wall using conventional support structures (brackets, foundations, floor slabs), then the thermal insulation and weather protection are improved, but the installation becomes time-consuming, labor-intensive, and costly
Solution Approach 1:
The patent extracts and eliminates the complex support structures (brackets, foundations, floor slabs) from the wall cladding system. By using a adhesive-based direct attachment method, the invention removes the intermediate support elements that previously were necessary to hold the brick wall layer, thereby simplifying the overall system and accelerating installation.
Solution Approach 2:
The patent introduces an adhesive layer as an intermediary substance between the existing wall and the additional brick wall layer. This adhesive mediator enables direct bonding without mechanical support structures, resolving the contradiction by providing both structural connection and thermal insulation functionality through a single simplified system.
2Stability of the object's composition
If complex support structures (brackets, foundations, floor slabs) are installed to support the additional brick wall layer, then the wall structure is stabilized, but the installation becomes difficult in areas with larger window openings
Solution Approach 1:
The patent removes the complex mechanical support structures from the system, eliminating the difficulty of installing them around window openings. The adhesive-based direct attachment method allows flexible installation in areas with larger window openings without requiring precise positioning of brackets or foundations.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (brackets, foundations) to chemical (adhesive bonding). This parameter change in the attachment method enables easier operation and installation, particularly in challenging areas like around window openings, while maintaining adequate structural stability through the adhesive bond.
3Strength
If conventional support structures are used to attach the additional brick wall layer, then the bricks are securely fastened, but the installation costs and labor requirements increase significantly
Solution Approach 1:
The patent extracts and eliminates the expensive mechanical support structures (brackets, foundations, floor slabs) from the installation system. By using adhesive-based direct attachment, the invention removes these costly intermediate elements while maintaining adequate brick fastening strength through the adhesive bond.
Solution Approach 2:
The patent uses an adhesive layer as an intermediary that provides both structural fastening and cost reduction. This adhesive mediator replaces expensive mechanical support structures, achieving secure brick attachment at lower material and labor costs while simplifying the overall installation process.

AI summary
The multi-layer wall (10) comprises several bricks (12) that are glued at inside and outside of a wall portion (18) such that a supplementary brick wall layer (20) is formed. A finery layer (16) is formed between the brick wall layer and wall portion through an adhesive layer (14).
