Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no back up detection system is installed, then the device complexity is low, but the safety and collision prevention capability is poor
Solution Approach 1:
The back up region is divided into multiple zones using a plurality of sensors positioned at different locations. Each sensor monitors a specific segment of the back up region, allowing the system to detect objects at various positions and distances behind the ride-on equipment independently and comprehensively
Solution Approach 2:
The sensor system serves multiple functions: detecting objects, determining their locations, identifying living beings through IR sensors, and providing both auditory and visual warnings. This multi-functionality improves safety without requiring separate dedicated systems for each function
2Reliability
If high-frequency sound waves are emitted to deter living beings, then the deterrence effectiveness is improved, but the energy consumption increases
Solution Approach 1:
The deterrence device emits high-frequency sound waves in response to detected living beings rather than continuously. The controller activates the deterrence device only when needed based on sensor feedback, providing periodic action that maintains effectiveness while reducing overall energy consumption compared to continuous operation
Solution Approach 2:
The system uses IR sensors to detect thermal signatures of living beings and selectively activates the deterrence device only when living beings are detected, not for inanimate objects. This parameter-based selection (temperature detection) optimizes energy usage by activating the high-energy deterrence function only when necessary
3Measurement precision
If multiple sensors are used to detect objects in the back up region, then the detection precision and coverage are improved, but the device complexity and cost increase
Solution Approach 1:
The back up region is divided into multiple zones monitored by individual sensors positioned at different locations. This segmentation provides comprehensive coverage of the entire back up region and enables precise determination of object locations based on which specific sensors detect the object
Solution Approach 2:
The controller serves as an intermediary that processes feedback from multiple sensors, determines object presence and location, identifies living beings using IR sensor data, and coordinates the activation of deterrence and warning devices. This centralized processing simplifies the overall system architecture despite using multiple sensors
4Reliability
If both auditory and visual warnings are provided, then the warning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The display device serves multiple warning functions: providing visual alerts to the operator, indicating object detection status, and showing location information. The deterrence device provides auditory warnings. This multi-functionality achieves comprehensive warning coverage without requiring separate dedicated devices for each warning type

AI summary
A back up system for ride-on equipment includes a plurality of back up sensors configured to sense an object within a back up region of the ride-on equipment, a deterrence device configured to emit a sound, a display configured to display the sensed object, and a controller configured to: determine whether the sensed object is within the back up region based on feedback from the plurality of back up sensors, and activate, in response to determining that the object is within the back up region, the deterrence device and the display.
