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, making it difficult for users to access critical information during faults or maintenance.
Innovation Solution
The implementation of a persistent display that uses electrophoretic techniques to reflect light, allowing it to maintain image presentation without consuming significant power, using stored or induced voltage, and adjusting image data with minimal energy input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional display is used that requires constant electricity to illuminate and render images, then the display can continuously present information with active updating, but the operational cost increases and the display becomes non-functional during power outages
Solution Approach 1:
The display system operates periodically rather than continuously - the controller updates image data only when voltage is available, and the persistent display material maintains the displayed information without continuous power. This periodic updating approach allows the system to function during power outages while minimizing energy consumption during normal operation.
Solution Approach 2:
The persistent display material serves itself by maintaining displayed information without requiring continuous external energy input. Once image data is written to the persistent display, it retains the information autonomously, eliminating the need for continuous power supply to maintain the display state.
2Use of energy by moving object
If a persistent display using electrophoretic techniques is implemented to reduce power consumption, then the display can maintain image presentation without significant power, but the ability to dynamically update and adjust image data is limited
Solution Approach 1:
The display system dynamically adapts its operation based on available voltage. When voltage is available, the controller actively updates and adjusts image data on the persistent display. When voltage is unavailable, the system transitions to a static display mode, maintaining the last updated image without consumption of additional power. This dynamic behavior provides both low power consumption and adaptability.
Solution Approach 2:
The system changes operational parameters based on power availability - transitioning between active updating mode (when voltage is available) and maintenance mode (when voltage is unavailable). The controller adjusts the frequency and nature of image data updates based on the presence or absence of voltage, optimizing both power consumption and display functionality.
3Reliability
If voltage storage components are added to enable display operation during power outages, then the display reliability improves, but the device complexity and physical footprint increase
Solution Approach 1:
The patent extracts the voltage storage function from a separate dedicated component and integrates it into the existing power supply architecture. The voltage storage component is incorporated into the power supply system rather than being added as a separate display subsystem, reducing overall complexity while maintaining the ability to operate during power outages.
Solution Approach 2:
The voltage storage component serves multiple functions: it provides power during outages, buffers voltage fluctuations during normal operation, and supports the electrophoretic display's power requirements. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity.

AI summary
A system includes an industrial automation component configured to receive a first voltage from a voltage source to enable the industrial automation component to perform one or more operations, a mechanical device configured to generate a second voltage, and a display configured to present image data. The display is configured to maintain presentation of the image data in absence of the first voltage received from the voltage source or the second voltage received from the mechanical device. The system also includes processing circuitry configured to use the second voltage generated by the mechanical device to adjust the image data presented by the display when the first voltage is unavailable.
