Extruded Brick Cutting Knife for Hidden Water-Shedding Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade cladding bricks and slips are prone to water infiltration and lack aesthetic appeal, particularly when using slanted sides to reduce water penetration, which are aesthetically noticeable.
Innovation Solution
A cutting device with a transverse cutting knife having multiple partial blades at angled positions forms complex 3D structures in extruded bricks or slips, creating rectangular overlaps and allowing for fake joints, enhancing water resistance and aesthetic similarity to regular brickwork.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slanted sides are used to reduce water penetration, then water resistance is improved, but aesthetic appeal deteriorates because the slanted openings are aesthetically noticeable
Solution Approach 1:
The cutting blade is divided into multiple partial blades (first, second, third partial blades) that create multiple cutting faces on different sides of the brick. This segmentation allows formation of complex 3D structures with rectangular overlaps and fake joints, achieving both water resistance and aesthetic appeal simultaneously
Solution Approach 2:
The invention transitions from simple slanted sides to complex 3D structures by adding multiple cutting faces at different angles. The first, second, and third partial cutting faces create overlapping rectangular patterns that mimic traditional brickwork, moving the solution into three-dimensional space to achieve both functionality and aesthetics
2Reliability
If complex 3D structures with rectangular overlaps are formed, then aesthetic appeal and water resistance are improved, but device complexity increases
Solution Approach 1:
Multiple cutting functions are merged into a single transverse cutting knife by integrating first, second, and third partial blades on one blade structure. This allows the complex 3D structure to be formed in a single cutting operation, avoiding the need for multiple separate cutting devices or operations
Solution Approach 2:
The transverse cutting knife serves multiple functions simultaneously: it creates first, second, and third partial cutting faces, forms rectangular overlaps, and creates fake joints all in one cutting action. This multi-functionality reduces device complexity while achieving complex structural outcomes
