Persistent Electrophoretic Display for Self-Powered Automation Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial automation systems face challenges with power-consuming displays that require constant electricity to operate, leading to increased costs and limited functionality during power outages, as they cannot present information when power is unavailable.
Innovation Solution
The implementation of a persistent display that uses electrophoretic techniques to reflect light and present information without consuming significant power, allowing it to maintain image data presentation even when power is disconnected, utilizing stored or harvested energy for operation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional display is used to present information in an industrial automation component, then the display can show visualizations, but the display requires continuous electricity to maintain the presentation and cannot function during power outages
Solution Approach 1:
The patent replaces conventional electronic display technology with electrophoretic display technology that uses electrostatic forces to manipulate charged particles in a suspension medium. This substitution enables the display to maintain visualizations without continuous power, as the particles remain in position due to electrostatic attraction rather than requiring active electronic control
Solution Approach 2:
The electrophoretic display system is designed to maintain its display state passively without requiring continuous energy input. Once particles are positioned to form an image, they remain in place through electrostatic forces, allowing the display to serve itself and maintain information presentation during power outages
2Productivity
If a conventional display requiring continuous power is used, then the display can be updated in real-time, but the operational costs increase and the system is limited during power outages
Solution Approach 1:
Instead of continuous power application, the electrophoretic display uses periodic or intermittent power input to update or change displayed information. The display can be refreshed by applying voltage to reposition particles, but maintains its state between updates without power consumption, enabling cost-effective continuous information presentation
