Solution Overview
Problem
Existing brick production methods face challenges in achieving efficient production of bricks in different lengths and widths with excellent insulating properties, secure anchoring of insulating materials, and maintaining fire protection properties, while also being cost-effective and simple to manufacture.
Innovation Solution
Inserting molded bodies made of compressible insulating material, such as mineral fibers bonded with binders, into cavities of the bricks, which provide a friction fit and secure anchoring without additional attachment, allowing for identical cavity dimensions and efficient filling with insulating material elements of consistent width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating material is inserted into cavities of bricks, then thermal and sound insulation properties are improved, but the insulating material may not be securely anchored during brick cutting and usage
Solution Approach 1:
The insulating material is made compressible, allowing it to be inserted in a compressed state and then expand to fill the cavity completely. This volume change from compressed to expanded state creates secure anchoring through friction against the cavity walls, preventing the material from falling out during brick cutting and usage while maintaining excellent insulation properties.
2Adaptability or versatility
If bricks are produced in different lengths and widths to match various wall thicknesses, then adaptability to different building requirements is improved, but production complexity and cost increase
Solution Approach 1:
The cavity design uses standardized dimensions that can accommodate insulating material elements of consistent width regardless of the brick's external dimensions. This universal cavity specification allows the same insulating material elements to be used across bricks of different lengths and widths, simplifying production while maintaining adaptability to various wall thicknesses through standardized brick widths (e.g., 24 cm, 30 cm, 36.5 cm, 40 cm, 49 cm).
