Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If high-frequency heating is applied to conductive nanoink, then conductive patterns can be produced, but energy efficiency is low due to insufficient heat generation by conductive nanoparticles
Solution Approach 1:
The patent combines conductive nanoparticles with magnetic particles to create a composite ink formulation. The magnetic particles have high magnetic permeability and generate significant heat through magnetic hysteresis loss when exposed to high-frequency magnetic fields, while the conductive nanoparticles provide electrical conductivity. This composite approach allows the magnetic particles to act as heat generation enhancers that compensate for the low heat generation of conductive nanoparticles alone, thereby improving energy efficiency during the burning process.
2Productivity
If conventional conductive nanoink is used, then conductive patterns can be formed, but burning time is excessive due to low heat generation
Solution Approach 1:
The patent modifies the composition parameters of the ink by adding magnetic particles with specific magnetic permeability characteristics. This parameter change in the material composition enables the ink to respond more effectively to high-frequency magnetic fields, generating heat more rapidly and reducing the burning time required to form conductive patterns.
