Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current animal recognition systems using I&R labels face interference issues due to their small size and the presence of other electromagnetic sources, leading to weakened return signals and difficulty in distinguishing multiple labels within a detection zone.
Innovation Solution
The system employs multiple antennas arranged in subzones within the detection zone to receive discrete electromagnetic signals, allowing for interference reduction and precise location determination of labels, enabling independent detection of multiple labels without signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple labels are simultaneously present in the detection zone, then the quantity of detected objects increases, but the return signals from these labels interfere with each other
Solution Approach 1:
The detection zone is divided into multiple subzones, each monitored by a separate antenna. This segmentation allows the system to spatially separate and independently process return signals from different labels, preventing signal interference even when multiple labels are present simultaneously in the detection zone.
2Volume of moving object
If small I&R labels are used, then the label size is reduced, but the return signal strength decreases
Solution Approach 1:
By dividing the detection zone into subzones with dedicated antennas, the system concentrates receiving resources on smaller signal portions from each subzone. This segmentation compensates for the weaker return signals from small labels by reducing competing interference and enabling more focused signal processing.
Solution Approach 2:
The patent introduces an intermediary processing stage where receiving signals from multiple antennas are combined and processed together. This intermediary step allows weak return signals from small labels to be aggregated and enhanced through combined processing, compensating for their inherently lower signal strength.
3Adaptability or versatility
If electromagnetic interference from other sources is present, then the detection environment becomes more complex, but the reception of return signals is disrupted
Solution Approach 1:
The detection zone is segmented into subzones, each with its own antenna for receiving return signals. This spatial segmentation isolates the reception of return signals from specific subzones, reducing the impact of electromagnetic interference from other sources that may be present in different spatial locations within the overall detection zone.
