Engineering Contradiction Analysis
1Reliability
If traditional anti-impact protection systems are used without predictive functionality, then the barriers provide basic protection, but they are often destroyed or seriously damaged during collisions, leading to lengthy repair times and substantial costs
Solution Approach 1:
The system performs preliminary detection of moving objects and predicts potential collision trajectories before actual contact occurs. By identifying objects in the danger zone and calculating their movement vectors, the system triggers warnings to operators in advance, enabling them to take corrective action before the collision happens, thus preventing barrier damage entirely
Solution Approach 2:
The system continuously monitors the environment using sensors, processes the detected data to determine object positions and movement patterns, and provides real-time feedback through visual and audible warnings. This closed-loop feedback mechanism allows operators to respond to potential threats dynamically, adjusting their behavior to avoid collisions with the barriers
2Reliability
If traditional anti-impact protection systems are used without predictive functionality, then the system structure remains simple, but the system lacks the ability to detect and respond to potential collisions, resulting in frequent barrier damage
Solution Approach 1:
The system employs multi-functional sensors that simultaneously perform detection, tracking, and data collection tasks. The same sensor network used for collision prediction also gathers traffic flow data and operational statistics, enabling the system to serve multiple purposes including safety monitoring, traffic management optimization, and barrier positioning analysis without requiring separate dedicated systems
Solution Approach 2:
The patent introduces an intermediary processing layer that bridges the simple sensor inputs and the complex collision prediction algorithms. This intermediary layer pre-processes sensor data, filters relevant information, and prepares it for analysis, thereby managing system complexity while maintaining high detection accuracy and enabling scalable system deployment
3Measurement precision
If UWB sensors with multiple antennas are deployed for precise position determination, then collision prediction accuracy is improved, but the system complexity and cost increase
Solution Approach 1:
The system implements a hierarchical sensor deployment strategy where UWB sensors with multiple antennas are strategically positioned only at critical locations and angles necessary for accurate position determination. By optimizing the spatial distribution and angular coverage of sensors, the system achieves high measurement precision for collision prediction while minimizing the total number of complex sensors required, thereby controlling system complexity and cost

AI summary
The invention suggests an impact prevention and protection system in a specific area. It includes a TAG device and/or a first sensor associated with an operator and/or with a vehicle and a second sensor connected to an anti-impact barrier in the area. The TAG devices and sensors employed use the same radio frequencies for transmitting and receiving data. The TAGs have a radio transceiver, an antenna and a controller for managing the transmission. The sensors have three radio transceivers, each with an omnidirectional antenna, and a control unit for calculating the distance and the approach angle of the other sensors and TAGs in the vicinity. This information determines the probability of impact between a moving vehicle and the barrier, and can be used to activate any safety procedures or alarms.
