Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional stock fitting processes are used with primers, adhesives, and solvents, then bonding between different parts can be achieved, but the process becomes labor-intensive and multi-step
Solution Approach 1:
The patent extracts and eliminates the need for separate primers, adhesives, and solvents from the traditional bonding process. The substrate itself is modified through surface treatment to provide inherent bonding capabilities, removing multiple chemical components and process steps while maintaining bonding reliability
Solution Approach 2:
The patent combines the functions of substrate preparation, adhesion promotion, and bonding into a single integrated process. The surface-treated substrate directly bonds to the material without requiring separate application of primers and adhesives, simplifying the overall process while maintaining strong adhesion
2Reliability
If traditional multi-step processes with primers and adhesives are used, then adhesion can be achieved, but production time and labor increase
Solution Approach 1:
The substrate undergoes preliminary surface treatment that creates bonding-capable groups directly on the substrate surface. This preliminary modification eliminates the need for subsequent primer and adhesive applications, reducing production time and labor while ensuring strong adhesion from the start
Solution Approach 2:
The substrate is modified to provide its own bonding functionality through surface treatment. Instead of requiring external adhesives and primers, the treated substrate surface itself enables direct bonding to the material, making the system self-sufficient and more efficient
3Strength
If chemical bonds including siloxane, silanol, and silyl linkages are formed in the bonding layer, then adhesive strength increases about 10 fold or more, but the process requires specialized surface treatment
Solution Approach 1:
The patent changes the chemical parameters of the substrate surface through treatment processes that introduce silane groups and create reactive bonding sites. This modification enables the formation of strong siloxane, silanol, and silyl linkages with the material, achieving 10-fold or more increase in adhesive strength while making the manufacturing process more straightforward by eliminating multiple chemical application steps
