Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic products with display panels, such as smartphones and TVs, face limitations in communications capabilities, particularly in terms of information reception and emission due to variations in the orientation of modulating electrodes, which affect the orientation of the modulating medium and the efficiency of electromagnetic radiation.
Innovation Solution
The electronic modulating device incorporates a first and second modulating unit with transistors and modulating electrodes arranged at different included angles between the extending direction of the channel and the longitudinal direction of the modulating electrode, allowing for improved orientation control of the modulating medium and reduced variations in information reception and emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modulating electrodes are arranged in a single longitudinal direction, then the device structure is simple, but the communication capability varies with receiver location
Solution Approach 1:
The modulating electrode is divided into multiple segments (first modulating electrode segment, second modulating electrode segment, third modulating electrode segment) arranged at different longitudinal directions. Each segment can independently modulate the modulating medium, enabling the device to communicate with receivers at various locations simultaneously, thus improving adaptability while maintaining manageable structural complexity
Solution Approach 2:
Different segments of the modulating electrode are assigned different longitudinal directions (first, second, and third longitudinal directions) to create localized modulation zones. This allows each segment to optimize its performance for specific receiver directions, achieving superior overall communication capability across multiple orientations
2Manufacturing precision
If all modulating electrode segments are parallel, then manufacturing is easier, but lithography and etching process variations have greater impact
Solution Approach 1:
The modulating electrode segments are intentionally arranged at different longitudinal directions rather than all being parallel. This asymmetric configuration reduces the cumulative impact of lithography and etching process variations by distributing orientation-dependent errors across different directions, thereby improving overall manufacturing precision
Solution Approach 2:
The electrode segments are arranged in multiple longitudinal directions (first, second, and third directions) rather than a single direction. This dimensional diversification allows the system to compensate for manufacturing variations in any single direction, as the other directions provide redundant modulation pathways
3Reliability
If modulating electrodes are arranged at different included angles, then information reception and emission is more consistent, but the device structure becomes more complex
Solution Approach 1:
The multiple modulating electrode segments arranged at different longitudinal directions collectively provide universal communication capability in all directions. Each segment serves multiple functions by contributing to both its primary direction and assisting adjacent directions, achieving consistent information reception and emission without requiring fully independent complex modulating units for each direction
