Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all components (light-emitting units, driving circuit, controlling circuit) are integrated on a single substrate, then device complexity is reduced and wiring design is simplified, but manufacturing precision requirements increase and damage risk during transportation increases
Solution Approach 1:
The patent divides the electronic device into multiple independent substrates: a first substrate for light-emitting units, a second substrate for the driving circuit, and a third substrate for the controlling circuit. This segmentation allows each substrate to be manufactured and tested independently, reducing the overall manufacturing precision requirements while maintaining simplified wiring design through standardized inter-substrate connections.
2Device complexity
If all components are integrated on a single substrate, then device structure is simplified, but the device becomes more vulnerable to damage during transportation
Solution Approach 1:
By segmenting the device into multiple substrates connected through flexible connection structures, the patent enables each substrate to be independently packaged and protected. The connection structures between substrates are designed to absorb mechanical stress, making the overall device more resistant to damage during transportation while maintaining structural simplicity.
3Device complexity
If driving transistors are integrated with light-emitting units on the same substrate, then device structure is simplified, but energy conversion efficiency decreases due to lower electron mobility
Solution Approach 1:
The patent separates the driving circuit onto a dedicated second substrate, allowing the use of high electron mobility materials and optimized transistor designs for the driving function. This segmentation enables the driving transistors to achieve higher electron mobility and energy conversion efficiency while keeping the overall device structure manageable through standardized inter-substrate connections.
4Speed
If controlling circuit is positioned close to light-emitting units, then control signal transmission is faster, but the device becomes more susceptible to damage from external forces
Solution Approach 1:
The patent positions the controlling circuit on a separate third substrate that can be strategically located away from high-stress regions. The inter-substrate connection structures are designed to protect control signals from external interference while maintaining adequate signal transmission speed through optimized connection paths and shielding.
