Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes and transistors are included to apply voltage to each capsule, then image display function is achieved, but thickness and flexibility are compromised
Solution Approach 1:
The patent extracts and removes the complex electrode and transistor structures from each capsule, retaining only the essential electrophoretic particles and enclosure. This extraction eliminates the thickening components while preserving the core image display functionality through simplified voltage application methods.
Solution Approach 2:
The patent employs flexible encapsulation structures and thin film layers to replace rigid electrode-transistor assemblies. The flexible shell design allows the display to achieve thinness and bendability while maintaining the electrophoretic display function through alternative voltage application architectures.
2Reliability
If electrodes and transistors are included to apply voltage, then image display function is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the unnecessary complex components (transistors and individual electrodes per capsule) from the system, keeping only the essential electrophoretic particles and enclosure. This simplification reduces device complexity while maintaining image display capability through streamlined voltage application.
Solution Approach 2:
The patent implements a universal voltage application mechanism that can control multiple capsules through a simplified structure. Instead of requiring individual transistors for each capsule, a multi-functional voltage application system is used that reduces overall structural complexity while achieving the same display function.
3Reliability
If conventional electrophoretic display structure is used, then image display is achieved, but production cost increases
Solution Approach 1:
The patent removes expensive components such as individual transistors and complex electrode structures from each capsule, retaining only the essential electrophoretic particles and simple enclosure. This extraction of non-essential components significantly reduces material costs and simplifies manufacturing processes while preserving display functionality.
Solution Approach 2:
The patent adopts a design approach that uses simpler, more cost-effective materials and structures that can be manufactured at lower costs. The simplified capsule structure with basic electrophoretic particles and simple voltage application enables more economical production compared to complex transistor-based implementations.
