Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting events, such as goals in sports, face challenges in securely and reliably transmitting information about event occurrences to referees on the field, particularly in ensuring timely and tamper-proof communication.
Innovation Solution
A transmitter and receiver system designed to send and receive data packets independently of event occurrences, with each packet containing information about the number of events up to its transmission time, and transmitted within predetermined periods, ensuring secure and real-time communication through encryption and adjustable transmission times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data packets are transmitted only when events occur, then transmission bandwidth is reduced, but transmission delay increases and reliability decreases
Solution Approach 1:
The system transmits data packets periodically at predetermined transmission periods regardless of event occurrence. This periodic transmission ensures that event information is delivered reliably within bounded time intervals, preventing both excessive delay and bandwidth waste by maintaining a regular rhythm that balances timeliness with resource conservation.
Solution Approach 2:
The transmitter prepares and transmits data packets in advance according to a predetermined schedule, ensuring that event information is already available for transmission before events occur. This preliminary preparation eliminates waiting time and ensures immediate transmission capability when events happen, improving reliability without requiring continuous monitoring.
2Loss of time
If data packets are transmitted frequently to ensure real-time updates, then transmission delay is reduced, but transmission bandwidth consumption increases
Solution Approach 1:
By establishing fixed transmission periods, the system achieves predictable and efficient bandwidth utilization. The periodic nature allows the receiver to anticipate packet arrivals, optimize its reception timing, and manage power consumption effectively, while ensuring that event information is transmitted within bounded time intervals without continuous high-bandwidth usage.
Solution Approach 2:
The system dynamically adjusts transmission parameters including packet content based on event occurrence and transmission timing. When events occur, packets contain event information; otherwise, they contain status updates or acknowledgments. This parameter adaptation optimizes bandwidth usage by transmitting only necessary information at appropriate intervals rather than continuous high-rate transmission.
3Productivity
If transmission periods are shortened to improve real-time performance, then transmission delay is reduced, but system complexity increases
Solution Approach 1:
The periodic transmission structure provides a simple yet effective framework for real-time performance. By using fixed, predictable intervals, the system avoids the complexity of dynamic scheduling algorithms while ensuring bounded latency. The regular rhythm simplifies both transmitter and receiver design, as they can synchronize to the known period without complex coordination protocols.
4Reliability
If continuous transmission is used to ensure security and reliability, then transmission reliability is improved, but energy consumption increases
Solution Approach 1:
Periodic transmission with predetermined intervals provides continuous coverage and security without requiring constant active transmission. The regular schedule ensures that the channel remains engaged and monitored, maintaining security and reliability, while the gaps between periods allow the transmitter to enter low-power states, significantly reducing energy consumption compared to continuous transmission.

AI summary
Embodiments relate to a transmitter (10, 54, 56) and/or a receiver (18, 60) for a system for detecting an event that is triggered by an object (12) crossing over a monitored line (14). The transmitter (10, 54, 56) is designed to successively send data packets (16) independently of an occurrence of the event. The receiver (18, 60) is designed to receive successive data packets (16) independently of the occurrence of the event. Each of the data packets (16) comprises information on a number (E1) of events that occurred up to a transmission time (Tn) of the data packet, wherein the transmission times (Tn) of successive data packets (16) each lie within a predetermined transmission period (TWindow).
