Solution Overview
Problem
Current start signal systems for track and field events are expensive and lack precision, especially for non-championship meets, often frightening younger participants and lacking in athlete performance feedback, with existing solutions being complex and costly.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional start signal systems (gunshots, horns, whistles) are used, then the start signal can be emitted, but the system is expensive and lacks precision for non-championship meets
Solution Approach 1:
The patent replaces traditional mechanical/acoustic start signal systems (gunshots, horns, whistles) with an electronic system using a computing device, start race device, and strobe sensor device. This substitution enables precise timing and synchronization of start signals with countdown sequences while reducing overall system complexity and cost for non-championship events.
Solution Approach 2:
The patent introduces a computing device as an intermediary that coordinates between the start race device (signal emitter) and strobe sensor device (detection device). This intermediary manages the synchronization between countdown sequences and start signals, providing precise control without requiring complex integrated systems.
2Object-affected harmful factors
If gunshot start signals are used, then the start signal is audible, but younger participants and audience members may be unnecessarily frightened
Solution Approach 1:
The patent changes the parameter of the start signal from high-decibel acoustic waves (gunshots) to visual strobe lights and synchronized audio cues controlled by a computing device. This parameter change maintains start signal effectiveness while eliminating the frightening effect on younger participants and audience members.
Solution Approach 2:
The patent converts the harmful acoustic shock of gunshots into beneficial visual and controlled audio signals. The strobe sensor device and start race device work together to provide a start signal that is effective for timing purposes but harmless to participants and spectators.
3Measurement precision
If IAAF approved false start apparatus are used, then false starts can be detected with high precision, but the products are expensive and complex in set-up and use
Solution Approach 1:
The patent segments the false start detection function from the starting block itself, using a separate strobe sensor device positioned behind the athlete. This segmentation allows the detection system to be independent of the starting block design, simplifying both setup and operation while maintaining high detection precision through the sensor's ability to detect movement before the start signal.
Solution Approach 2:
The patent uses the computing device as an intermediary that processes data from the strobe sensor device to determine false starts. This intermediary simplifies the overall system by centralizing the detection logic and communication protocols, making the system easier to set up and operate compared to integrated IAAF approved apparatus.
4Measurement precision
If expensive detection equipment is used to determine fair starts, then detection accuracy improves, but the financial burden on event organizers increases
Solution Approach 1:
The patent creates a universal system where a single computing device with integrated start race device and strobe sensor device can handle multiple functions: emitting start signals, detecting false starts, and providing performance feedback. This multi-functionality eliminates the need for separate expensive detection equipment, reducing financial cost while maintaining detection accuracy.
Solution Approach 2:
The system uses the computing device's own processing capabilities and integrated sensors to perform detection functions, rather than requiring external specialized equipment. The strobe sensor device detects false starts and the computing device processes this information, allowing the system to serve itself and reducing overall system cost.
