PDU Data Retrieval via Mobile Device Optical Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution units (PDUs) often have displays that are too small to quickly retrieve and analyze operating conditions, and users face challenges in safely accessing data due to environmental conditions such as temperature, lighting, and space constraints.
Innovation Solution
A method and apparatus that includes a processor, memory, and display coupled with tracking circuitry within the PDU, allowing data conversion into a stream of character sets readable by mobile devices, which can interpret and present human-readable information, using LED or LCD displays that flash at frequencies not visible to the human eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a small display is used on the PDU, then the device complexity is reduced, but the ability to quickly retrieve and analyze operating conditions deteriorates
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the PDU and the user. The mobile device captures images of the display and processes the information, allowing the PDU to maintain a simple display while the mobile device handles the complex data analysis and presentation.
Solution Approach 2:
The patent transitions from a two-dimensional limited display on the PDU to utilizing the mobile device's screen and processing capabilities in a different dimensional space. This allows much more information to be presented in a user-friendly format without increasing the physical display size on the PDU.
2Loss of time
If direct access to PDU data is attempted, then information retrieval speed is improved, but safety deteriorates due to unsafe handling conditions
Solution Approach 1:
The mobile device serves as a safe intermediary that captures data remotely without requiring the user to physically interact with hazardous components. The system retrieves data through image capture and processing rather than direct electrical or physical connection.
Solution Approach 2:
The patent replaces direct mechanical/electrical connection methods with optical capture (camera imaging) and digital processing. This substitution eliminates the need for physical contact with unsafe components while maintaining data retrieval capability.
3Reliability
If environmental conditions are improved for safe access, then user safety is improved, but the ability to quickly retrieve data deteriorates due to space constraints
Solution Approach 1:
The mobile device acts as a mediator that bridges the gap between safety requirements and quick data access. It can capture data from a safe distance without requiring the user to enter hazardous zones or manipulate physical components.
Solution Approach 2:
The system performs preliminary actions by capturing the display image and processing the data in advance, allowing the user to retrieve information quickly without needing to physically approach or interact with the PDU components.
