Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating physical collectibles at events lack real-time association with event-based data, and traditional RFID scanning systems are not equipped to capture images and RFID data simultaneously at a distance.
Innovation Solution
A radio frequency identification (RFID) scanning system that includes a gimbal connecting the RFID reader to a camera, allowing for single-handed operation and stabilization of the camera while the RFID reader moves to scan RFID tags at a distance, thereby capturing images and RFID data for event-based authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the RFID reader is moved about one or more axes to scan RFID tags at a distance, then the scanning capability and authentication capability are improved, but the camera stability deteriorates
Solution Approach 1:
The system divides the device into two independent functional modules: an RFID reader module that can move freely to scan tags, and a camera module that remains stabilized. This segmentation allows each component to perform its function optimally without interfering with the other.
Solution Approach 2:
A gimbal mechanism serves as an intermediary between the moving RFID reader and the camera. The gimbal absorbs and compensates for movements, acting as a buffer that isolates the camera from the RFID reader's motion while maintaining their functional connection.
2Adaptability or versatility
If the RFID reader and camera are integrated in a single system, then the authentication capability is improved through simultaneous image and RFID data capture, but the device complexity increases
Solution Approach 1:
The integrated system is segmented into distinct functional modules (RFID reader, camera, gimbal, processing unit) that can be independently designed, tested, and maintained. This modular architecture reduces overall system complexity while enabling advanced authentication capabilities.
Solution Approach 2:
The system combines multiple functions (RFID scanning, image capture, stabilization, and authentication processing) into a single multi-functional device. This universality allows the system to perform both RFID data collection and visual documentation simultaneously, enhancing authentication capability without requiring separate devices.
3Measurement precision
If the camera is stabilized using a gimbal during RFID scanning, then the image quality is improved, but the device complexity increases
Solution Approach 1:
The gimbal acts as an intermediary stabilization mechanism between the moving RFID reader and the camera. It introduces minimal complexity by providing mechanical stabilization through gyroscopic principles, significantly improving image quality while adding only the necessary components for stabilization.
Solution Approach 2:
The system could potentially replace the mechanical gimbal with electronic image stabilization or software-based correction methods, which would reduce mechanical complexity while maintaining image quality. However, the mechanical gimbal provides more reliable stabilization for this application.
