Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID technology is used for participant identification and timing, then identification accuracy is improved, but system cost and environmental impact increase
Solution Approach 1:
The patent replaces RFID chips with QR codes printed on bibs, using a visual copy (optical pattern) instead of an electronic component. This eliminates the need for expensive RFID hardware while maintaining identification capability through camera-based scanning. The QR code serves as a lightweight, cost-effective alternative that achieves the same identification function without electronic complexity.
Solution Approach 2:
The patent substitutes the electronic RFID system with an optical-mechanical system using cameras and QR code scanning. Instead of using electromagnetic fields and RFID readers, the system uses visual capture devices to read printed codes, replacing complex electronic infrastructure with simpler optical detection that reduces overall system cost and environmental impact.
2Productivity
If manual intervention is used in race management processes, then system simplicity is maintained, but processing speed and efficiency decrease
Solution Approach 1:
The patent implements automated self-service functionality where cameras automatically capture participant images, AI algorithms automatically identify participants and match them with bib numbers, and the system automatically records timing data. This eliminates the need for manual registration, packet distribution, and timing recording, allowing the system to process participants autonomously at high speed without human intervention.
Solution Approach 2:
The system performs preliminary actions by pre-processing participant images and data during registration, organizing information in advance so that during the race, only simple recognition and matching are needed. This preliminary preparation enables rapid automated processing during the event without requiring manual intervention at critical moments.
3Adaptability or versatility
If traditional race management systems are used, then implementation simplicity is maintained, but participant experience and content richness decrease
Solution Approach 1:
The patent creates a multi-functional system where the same camera infrastructure serves multiple purposes: capturing participant images for identification, recording race timing, enabling social media sharing, and providing race day photography services. This universal system handles registration, timing, communication, and entertainment functions through a single integrated platform, enhancing participant experience without proportionally increasing complexity.
Solution Approach 2:
The patent merges previously separate functions (registration systems, timing systems, communication systems, and photography services) into a single integrated AI-based platform. By combining these functions that share common infrastructure (cameras, processors, databases), the system delivers rich participant experiences including real-time updates, social sharing, and personalized content while managing complexity through unified architecture.
Data Source
AI summary
A system for tracking competitors conducting a race on a track includes multiple object-recognition devices positioned to recognize objects at predetermined locations along the track. The object-recognition devices are configured to recognize at least one physical feature of each of the competitors. A processing device is configured to determine a time at which a competitor reached a selected one of the predetermined locations during the race based on object-recognition data from at least one of the object-recognition devices. A transmitter is configured to transmit to an output device the time at which the competitor reached the selected location during the race.
