Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a global economy, the challenge lies in detecting counterfeited products effectively, as they can be difficult to distinguish from authentic ones due to the complexity of replicating dynamic sensor measurements and transport paths, posing risks to both manufacturers and consumers.
Innovation Solution
A system utilizing a sensor unit associated with products to measure environmental parameters like temperature and light intensity, comparing these measurements with a transport profile to identify deviations and determine the authenticity of products, with authentication protocols ensuring secure data exchange and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor units are used to measure environmental parameters during transport, then product authentication capability is improved, but device complexity increases
Solution Approach 1:
The authentication system is divided into separate functional modules: sensor units attached to products for data collection, communication units for data transmission, and processing systems for analysis. This segmentation allows each component to perform its specific function independently, improving authentication capability while managing overall system complexity through modular design
Solution Approach 2:
Sensor units continuously collect and store environmental parameter data (temperature, humidity, light, shock) throughout the transport process before authentication is required. This preliminary data collection enables reliable authentication by having measurement data ready in advance, eliminating the need for complex real-time measurement systems during verification
2Reliability
If dynamic sensor measurements are used for authentication, then counterfeit detection reliability is improved, but measurement precision requirements increase
Solution Approach 1:
The system moves from checking single static product attributes to analyzing multi-dimensional temporal data patterns. By examining how environmental parameters change over time during transport (temperature fluctuations, humidity variations, light exposure sequences, shock events), the system creates a unique dynamic fingerprint that is difficult to counterfeit, reducing reliance on ultra-precise single-point measurements
Solution Approach 2:
The system compares actual sensor measurements against expected transport profiles that define valid ranges and patterns for authentic products. This feedback mechanism automatically identifies deviations that indicate counterfeiting, maintaining high detection reliability while accommodating normal measurement variations through profile-based validation
3Productivity
If automated detection systems are implemented, then productivity of authentication process is improved, but device complexity increases
Solution Approach 1:
The sensor units autonomously collect, store, and transmit their own measurement data without requiring manual intervention. The processing system automatically retrieves data from multiple sensor units, compares it against transport profiles, and generates authentication results. This self-service automation increases throughput while managing complexity by distributing intelligence across independent units rather than requiring a centralized complex system

AI summary
Implementations may include a computer system for detecting counterfeited products. The system may include a communication unit and a processing unit. The communication unit may be configured to receive a representation of sensor data being measured at different times by a sensor unit associated with a product. The processing unit may be configured to compute a deviation of the sensor data from data of a transport profile for the product and to compute from the deviation a counterfeit value representing an estimate value for the probability that the product is counterfeited.
