Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual inspection methods are used to detect counterfeit goods, then the process is simple and non-intrusive, but the detection accuracy is insufficient and cannot reliably identify hidden counterfeit components
Solution Approach 1:
The patent replaces traditional visual inspection methods with electromagnetic induction heating technology. The induction heating device generates electromagnetic fields that penetrate the product packaging and heat ferromagnetic materials internally, allowing detection of counterfeit goods through thermal signals without physical contact or invasive methods.
Solution Approach 2:
The system changes the physical state of ferromagnetic materials by applying electromagnetic induction heating. By controlling the heating parameters and detecting temperature changes, the system can identify counterfeit goods that contain different ferromagnetic material compositions or structures compared to legitimate products.
2Reliability
If induction heating is applied to heat ferromagnetic materials for authentication, then the authentication capability is enhanced, but the ferromagnetic materials may be damaged or altered
Solution Approach 1:
The induction heating device applies electromagnetic energy in controlled portions, heating only the specific ferromagnetic materials within the product being inspected. The heating intensity and duration are precisely controlled to achieve sufficient thermal signals for authentication while preventing excessive heating that would damage the product or its packaging.
Solution Approach 2:
The system incorporates temperature sensing and control mechanisms that provide feedback during the induction heating process. By monitoring the temperature rise in real-time, the system can adjust the heating power dynamically to ensure authentication accuracy while preventing material damage or overheating.
3Productivity
If electromagnetic radiation is used to heat materials for detection, then the detection speed is improved, but the energy consumption increases
Solution Approach 1:
The induction heating device generates electromagnetic fields that are concentrated and directed specifically at the ferromagnetic materials within the product being inspected. This localized heating approach ensures that energy is applied only where needed for detection, rather than heating the entire product or surrounding environment, thereby reducing overall energy consumption while maintaining fast detection speeds.

AI summary
A method of analyzing shipments of goods includes receiving, by a transceiver of a shipment analysis system, a heat map template, where the heat map template is an expected heat map for a plurality of packages in a shipment. The method also includes directing electromagnetic radiation from an electromagnetic radiation source to the package to heat any ferromagnetic material in or on a package. The method also includes generating, by a processor of the shipment analysis system, a heat map based on the heating of any ferromagnetic material in or on the package. The method further includes generating, by the processor, an alert responsive to a determination that the generated heat map does not match the heat map template. The alert indicates that the package is not one of the plurality of packages in the shipment.
