Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing brick slips fail to profile the transverse edges during extrusion, leading to alignment and stability issues when used in building structures.
Innovation Solution
A method involving extrusion followed by post-extrusion processing to form tongues and grooves on the transverse edges of brick slips, ensuring alignment and stability through a tongue-and-groove profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If brick slips are manufactured by extrusion only, then the manufacturing process is simple, but the transverse edges cannot be profiled leading to poor alignment and stability
Solution Approach 1:
The tongue and groove profiles are formed on the transverse edges of the brick slips during the extrusion process itself, before the brick slips are installed. This preliminary formation of the interlocking features ensures precise alignment and stability without requiring additional processing steps later, thus improving manufacturing precision while controlling device complexity.
2Reliability
If brick slips are manufactured by extrusion only, then the manufacturing process is fast, but the brick slips lack stability against wind and structural movement
Solution Approach 1:
The interlocking tongue and groove features are created during extrusion, preparing the brick slips for stable assembly before installation. This preliminary action ensures that when brick slips are installed, they automatically interlock to resist wind loads and structural movement, improving reliability without significantly impacting manufacturing speed since the features are formed during the primary extrusion process.
3Manufacturing precision
If tongue and groove profiles are added after extrusion, then alignment and stability are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The formation of the tongue and groove profiles on the transverse edges is merged with the extrusion process itself. By integrating these profiling operations into the extrusion stage, the patent eliminates the need for separate post-extrusion processing steps, thus improving manufacturing precision while reducing overall process complexity.
Solution Approach 2:
The tongue and groove features are formed preliminarily during extrusion rather than as a subsequent operation. This preliminary formation of critical alignment features ensures precision is achieved during manufacturing rather than requiring additional complex processing steps after extrusion.
