Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple panels with antennas are used for RFID anti-theft detection, then detection reliability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines multiple antenna functions into a single integrated panel structure. The single panel contains multiple antennas (at least two) that work together to detect RFID tags from different directions, eliminating the need for multiple separate panels while maintaining comprehensive detection coverage.
Solution Approach 2:
The single panel is designed to perform multiple detection functions simultaneously. It can detect RFID tags passing through from both sides of the panel and from multiple directions (front, back, left, right) using its integrated multiple antennas, making it a universal detection unit that replaces multiple specialized panels.
2Adaptability or versatility
If multiple panels with antennas are used for RFID anti-theft detection, then detection coverage is improved, but installation cost and logistical complexity increase
Solution Approach 1:
Multiple antenna systems are merged into a single manufacturable panel unit. The panel integrates at least two antennas with different orientations (one parallel to the panel plane, one perpendicular) that can be manufactured together as a single component, reducing installation complexity and cost while maintaining comprehensive detection coverage.
Solution Approach 2:
The patent adds spatial dimensionality to detection coverage by using antennas oriented in different directions (parallel and perpendicular to the panel). This three-dimensional antenna arrangement provides omnidirectional detection capability from a single panel, eliminating the need for multiple panels installed in different locations.
3Device complexity
If a single panel with multiple antennas is used, then device complexity is reduced, but detection capability in three dimensions may be compromised
Solution Approach 1:
Different regions of the single panel are equipped with antennas having different local orientations and detection characteristics. One antenna is oriented parallel to the panel plane while another is perpendicular, creating local detection zones that together cover all three spatial dimensions. This local quality differentiation ensures comprehensive detection precision while maintaining a simple single-panel structure.

AI summary
A radio frequency detection device configured to detect RFID tags, comprising a single double-loop RFID antenna, an RFID reader (13), connection cables (17), longitudinal conductive section bars (29a) and transverse conductive section bars (29b, 29c) which form a closed circuit, which also comprises a transverse branch (14) connecting said longitudinal section bars (29a) so as to form a double-loop circuit which is crossed by current and which provides an electromagnetic field able to detect, in three dimensions, RFID tags even on both sides of a single panel (11) of antennas. The possibility of superimposing an RFID antenna, which is the object of the present invention, with other antennas with electromagnetic technology allows to obtain an "hybrid" gate with a simultaneous reading of RFID tags and electromagnetic tags or bars.
