Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If barcodes or QR codes are used for unique identification, then they are easy to reproduce, but they are expensive to read
Solution Approach 1:
The patent replaces optical/magnetic reading systems with acoustic wave-based reading. Dielectric waveguide filaments are excited by acoustic waves and generate unique response signals that can be read by simple acoustic sensors, eliminating the need for complex optical scanners or RFID readers while maintaining ease of reproduction through simple physical structures
Solution Approach 2:
The patent changes the reading mechanism from optical/electromagnetic parameters to acoustic parameters. By using acoustic waves to excite and read the dielectric waveguide filaments, the system achieves low-cost reading infrastructure while the unique physical arrangement of filaments provides secure, hard-to-copy identification
2Reliability
If RFID tags with metal antennas are used, then they provide unique identification, but they cannot withstand harsh electromagnetic environments
Solution Approach 1:
The patent replaces metal-based electromagnetic RFID antennas with dielectric waveguide filaments that operate on acoustic wave principles. This substitution eliminates susceptibility to electromagnetic interference while maintaining unique identification capabilities through the acoustic excitation and measurement of response signals from the waveguide structure
Solution Approach 2:
The patent uses dielectric materials (non-conductive plastics) instead of conductive metals for the waveguide filaments. This material choice provides immunity to electromagnetic interference while the unique physical arrangement and acoustic properties of the composite dielectric structure enable reliable unique identification
3Ease of manufacture
If circuits are printed with conductive inks, then they can be made, but they are complex to manufacture and not difficult to copy
Solution Approach 1:
The patent replaces complex conductive ink circuit printing with simple dielectric waveguide filament placement. The filaments can be arranged in unique three-dimensional configurations that are easy to manufacture but extremely difficult to replicate, providing both manufacturability and security against counterfeiting
Solution Approach 2:
The patent transitions from two-dimensional printed circuits to three-dimensional arranged dielectric waveguide filaments. This dimensional change enables unique spatial configurations that are simple to manufacture through layer-by-layer or random placement but extremely difficult to copy accurately, enhancing security while maintaining ease of manufacture
4Reliability
If existing identification methods are used, then they can identify objects, but they are too large for certain applications
Solution Approach 1:
The patent divides the identification system into minute dielectric waveguide filaments that can be individually placed or embedded. These segmented filaments create a compact identifier that maintains full identification capability while being small enough for applications requiring minimal space, such as embedding in small objects or tissues
Solution Approach 2:
The patent uses thin dielectric waveguide filaments that can be flexibly arranged and embedded in various forms and sizes. This enables the creation of compact, adaptable identifiers that fit within space-constrained applications while maintaining the unique identification capability through the filament arrangement pattern
