Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the electronic device operates at lower temperatures, then energy consumption is reduced, but folding reliability deteriorates due to thermal issues causing cracking and reduced durability
Solution Approach 1:
The heat generating module performs preliminary heating action before folding operations to maintain optimal temperature levels. By proactively generating heat in advance, the system prevents thermal-related cracking and durability issues that would otherwise occur during folding, thus maintaining reliability without requiring continuous high energy consumption.
Solution Approach 2:
The heat generating module operates periodically rather than continuously, activating only when temperature conditions require heating. This periodic operation allows the device to maintain folding reliability through targeted thermal management while minimizing overall energy consumption by keeping the heating function dormant during adequate temperature periods.
2Reliability
If a heat generating module is added to the input sensor, then folding reliability is improved through temperature maintenance, but device complexity increases
Solution Approach 1:
The heat generating module is merged with the input sensor structure, sharing common elements such as the substrate and insulating layers. By combining these functions into a single integrated module rather than separate components, the patent reduces overall device complexity while still achieving the desired temperature maintenance for improved folding reliability.
Solution Approach 2:
The input sensor structure serves multiple functions: it acts as both a sensing element and a platform for the heat generating module. The shared substrate, insulating layers, and electrode structures provide both sensing capability and thermal generation/management functions, thereby reducing the need for additional separate components and simplifying the overall device architecture.
