Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-impact protection systems are used to protect infrastructures and operators, then safety is improved, but the systems are often destroyed or seriously damaged during collisions leading to lengthy repairs and operational disruptions
Solution Approach 1:
The system performs preliminary detection of potential collisions using UWB sensors and angle of arrival techniques before the actual impact occurs. By identifying approaching objects and calculating collision risk in advance, the system can trigger warnings or preventive actions, allowing the barrier to avoid destruction entirely or be replaced much quicker since it may not have been damaged at all.
2Strength
If traditional anti-impact protection systems are installed, then physical protection is provided, but they lack predictive collision avoidance capabilities requiring substantial repair costs and time
Solution Approach 1:
The system continuously monitors the environment using UWB sensors and provides real-time feedback about object positions, speeds, and collision risks. This feedback loop allows the system to detect potential threats, warn operators, and potentially prevent collisions before they occur, eliminating repair time entirely when prevention succeeds, or enabling much faster response when intervention is needed.
3Measurement precision
If UWB sensors with multiple antennas are implemented for collision prediction, then collision detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system uses multiple antennas arranged in specific geometries to detect signals from three-dimensional space, enabling accurate determination of angle of arrival and object position. By adding the spatial dimension through multiple sensing elements, the system achieves precise collision prediction capability without requiring overly complex processing, as the geometric arrangement of antennas provides natural spatial discrimination.

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.
