Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual scanning method is used to read RFID tags, then equipment cost is reduced, but checking time increases greatly
Solution Approach 1:
The patent replaces manual mechanical scanning operations with an automated electromagnetic field-based reading system. The leaking-waved antenna net unit generates electromagnetic waves that automatically trigger RFID tags within the cabinet, eliminating the need for manual swiping motions and significantly reducing checking time while maintaining operational simplicity through automatic activation.
2Productivity
If triggering range is extended to cover entire cabinet, then reading efficiency improves, but equipment cost increases
Solution Approach 1:
The patent divides the cabinet interior into multiple reading zones by installing leaking-waved antenna net units on different walls or sections. Each antenna net unit covers a specific region, and the segmented approach allows the entire cabinet to be covered without requiring a single complex high-power antenna system, thus improving reading efficiency while controlling equipment complexity and cost.
3Reliability
If metal cabinet structure is used for security, then security is improved, but RFID signal transmission is blocked
Solution Approach 1:
The patent introduces leaking-waved antenna net units as intermediary devices that generate electromagnetic waves capable of penetrating or bypassing the metal cabinet structure. These antenna net units act as mediators between the RFID reader and the tags, creating an electromagnetic field that can trigger tags even through the metal shielding, thus maintaining both security and signal transmission capability.

Function Achieved in This Case
The solution significantly reduces checking time, minimizes the risk of lost or misplaced items, and lowers operational costs by enabling efficient, wide-range RFID tag triggering and information retrieval within the facility.
Implementation Method 1
an electromagnetic (EM) wave is generated due to the wave leaking while the current flows through the leaking-waved antenna net unit. Moreover, the EM wave is transmitted along the extension antennas, such that the radio frequency identification electronic tag on the objects is triggered by the electromagnetic field built up by the EM wave
Implementation Method 2
The first antenna is connected to the inner main antenna, and used to receiving the detecting signal from a reader unit. The first antenna generates a current while receiving a detecting signal from the reader unit

AI summary
A wireless radio frequency identification receiving facility having antenna net includes a receiving apparatus with receiving spaces for receiving objects, a leaking-waved antenna net unit, and a first antenna. The leaking-waved antenna net unit includes an inner main antenna and extension antennas extended to the regions adjacent to the receiving spaces. The first antenna receives the detecting signal from a reader unit and generates a current. The EM wave is generated while the current flows through the leaking-waved antenna net unit, and is transmitted along extension antennas. The radio frequency identification electronic tags on the objects are triggered by the electromagnetic field built up by the EM wave, and information of all objects in the receiving apparatus is read at one time, so that the checking time is greatly reduced and the possibility of lost and position mistake of object can be excluded.
