Digital Sign Pairing via Geometric Attribute Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital sign systems require manual input of identifiers for control devices to interact with digital signs, limiting convenience and flexibility, especially in environments where multiple digital signs are present.
Innovation Solution
A digital sign system that uses geometric attributes, such as directional and positional data, to automatically identify and pair control devices with digital signs, eliminating the need for manual input by determining unique digital sign identifications based on the control device's orientation and location relative to the digital signs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of identifiers is used for control devices, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical input (typing identifiers) with an automated optical/electromagnetic system. The control device captures an image of the digital sign, and image recognition technology automatically extracts the identifier, substituting the manual input process with automated visual recognition.
Solution Approach 2:
The system enables self-service pairing by allowing the control device to automatically identify and pair with the digital sign through image recognition. The user simply points the device at the sign, and the system autonomously completes the pairing process without requiring manual identifier entry or complex setup procedures.
2Productivity
If manual pairing process is used, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The digital sign displays its identifier visually (through QR code, barcode, or text) in advance, preparing the information for automatic capture. This preliminary presentation of the identifier enables the control device to quickly recognize and process the sign without requiring time-consuming manual entry or search procedures.
Solution Approach 2:
The patent replaces the time-consuming manual pairing process with automated image recognition technology. The control device captures an image of the digital sign and automatically extracts the identifier through optical character recognition or code scanning, dramatically reducing the time required for pairing compared to manual input methods.
3Ease of operation
If geometric attributes are used for automatic identification, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent replaces complex manual configuration processes with automated geometric attribute detection. The control device automatically detects its own position, orientation, and distance relative to the digital sign using sensors (accelerometers, gyroscopes, cameras), and the system uses these geometric attributes to automatically identify and pair with the correct sign without requiring manual setup.
Solution Approach 2:
The system performs self-service identification by automatically using the control device's geometric attributes (position, orientation, distance) to identify which digital sign the user intends to control. The user simply points the device at the desired sign, and the system autonomously calculates the geometric attributes and matches them to the corresponding digital sign.
4Ease of operation
If hardwiring is required for control, then reliability improves, but ease of operation deteriorates
Solution Approach 1:
The patent replaces physical hardwiring connections with wireless communication technology. The control device uses wireless protocols (Wi-Fi, Bluetooth, cellular) to communicate with the digital sign, eliminating the need for physical cables while maintaining reliable communication through automated connection establishment based on geometric attribute matching.

AI summary
A method for pairing a control device with a digital sign is provided. The method includes receiving control device geometric attributes and digital sign geometric attributes, determining a digital sign identification based on the control device geometric attributes and the digital sign geometric attributes, and transmitting the digital sign identification to the control device. The control device geometric attributes may define geometric attributes of the control device. The digital sign geometric attributes may define geometric attributes of the digital sign that the control device is attempting to control. The digital sign identification may define the digital sign that the control device.
