Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cheat-preventing mechanisms in pigeon racing competitions, which involve manual comparison of newspaper halves, are inefficient and prone to errors, leading to potential cheating and unfair results.
Innovation Solution
A system that converts contest encrypted codes into two-dimensional barcodes (QR codes) and uses RFID modules, allowing for automated verification through a computer apparatus and mobile communications device, with the option of a backup RFID system for additional security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual comparison of newspaper halves is used for verification, then the system is simple to implement, but the verification efficiency is low and prone to human error
Solution Approach 1:
The patent replaces the manual mechanical comparison process with an automated optical recognition system. QR codes are printed on newspaper halves, and a mobile device with camera automatically captures and compares these codes, substituting human visual inspection and manual comparison with automated image processing and code recognition algorithms.
Solution Approach 2:
The patent creates a digital copy of the verification data through QR codes that encode the contest information. Instead of comparing physical newspaper pieces directly, the system captures images of QR codes and processes these digital representations, enabling automated verification while maintaining the simplicity of physical newspaper distribution.
2Reliability
If only one verification mechanism (newspaper comparison) is used, then the system is simple, but the reliability against cheating is insufficient
Solution Approach 1:
The patent divides the verification system into two independent parallel mechanisms: (1) QR code comparison on newspaper halves, and (2) RFID tag verification. Each mechanism independently verifies contest information, and both must match for successful verification, creating a segmented multi-layered security approach that increases reliability without requiring a single complex system.
Solution Approach 2:
The patent prepares multiple verification mechanisms in advance (QR codes printed on newspaper and RFID tags embedded) before the contest begins. This preliminary preparation ensures that if one verification method fails or is compromised, the other mechanism is already in place to provide backup verification, cushioning against potential cheating attempts.
3Reliability
If RFID module is added as backup system, then the reliability increases, but the device complexity and cost increase
Solution Approach 1:
The patent makes the mobile device serve multiple functions: it captures QR code images for optical recognition, reads RFID tags through the camera module, and transmits verification data. This multi-functional approach reduces the need for separate dedicated devices for each verification method, thereby limiting the increase in system complexity despite adding RFID capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system significantly reduces manual intervention and increases the efficiency and security of code verification, effectively preventing cheating by using QR codes and RFID signals for double verification.
Implementation Method 1
The electronic ring of the pigeon ring usually includes a Radio Frequency Identification (RFID) module for being detected by a pigeon clock device (for example, an RFID sensing panel)
Implementation Method 2
identify images of the two-dimensional barcodes in the pigeon rings captured by the camera module of the mobile communications device
Implementation Method 3
The pigeon clock is connected to a Global Positioning System (GPS) module. The GPS module can perform global positioning and time-setting
