Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a small-sized RFID label is used for contactless authentication, then the space occupied by the antenna is reduced, but the degree of freedom for positioning is limited and communication reliability deteriorates
Solution Approach 1:
The patent transitions from a planar RFID label to a three-dimensional integrated antenna system embedded within the container structure. The antenna windings are arranged in multiple layers and orientations within the container wall thickness, utilizing the third dimension to achieve reliable communication without requiring a large surface area.
Solution Approach 2:
The container structure serves multiple functions: it contains the pharmaceutical product, provides structural support, and integrates the NFC antenna system. The container wall itself becomes part of the antenna assembly, eliminating the need for a separate label and enabling reliable communication with a compact footprint.
