Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monomer of a conductive polymer is printed on a base material to allow chemical polymerization reaction, then the conductive polymer can be adhered in a free shape, but bleeding is caused resulting in difficulty in adhering the conductive polymer with high accuracy
Solution Approach 1:
The base material is heated before applying the monomer solution, which preliminarily prepares the surface to immediately initiate polymerization upon monomer application. This preliminary heating action prevents bleeding by ensuring the polymerization reaction starts immediately when the monomer contacts the heated base material, thereby achieving both free shape adherence and high accuracy
Solution Approach 2:
The invention changes the temperature parameter of the base material to a heated state before monomer application. This parameter change accelerates the polymerization reaction rate, allowing the conductive polymer to form immediately in the desired shape without bleeding, thus resolving the contradiction between free shape versatility and adherence accuracy
2Ease of manufacture
If the conductive polymer is adhered to the base material by the chemical method, then the production process is simplified, but bleeding occurs making it difficult to achieve high accuracy in shape
Solution Approach 1:
Heating the base material before applying the monomer solution is a preliminary action that prepares the surface for immediate polymerization. This maintains the simplicity of the chemical method while preventing bleeding, thereby achieving both ease of manufacture and shape accuracy
Solution Approach 2:
Changing the temperature parameter of the base material to heated state accelerates the polymerization reaction, allowing the conductive polymer to adhere immediately in the desired shape without bleeding. This preserves the chemical method's simplicity while improving shape accuracy
