Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication and sensing systems are used, then security and traceability are provided, but cost and device complexity increase
Solution Approach 1:
The patent combines multiple functions (sensing, authentication, traceability, payment verification) into a single integrated blockchain optical sensor system. The optical sensor captures images that are processed by a camera on a mobile device, which then verifies blockchain codes and environmental data in one unified operation, eliminating the need for separate authentication devices and reducing overall system complexity.
Solution Approach 2:
The blockchain optical sensor is designed to perform multiple functions simultaneously: it provides product authentication through blockchain verification, environmental sensing through integrated sensors, traceability through immutable ledger recording, and even payment verification. This multi-functional approach replaces multiple separate systems with a single universal device.
2Reliability
If comprehensive sensing and authentication systems are implemented, then security and traceability improve, but cost increases
Solution Approach 1:
The system enables consumer self-verification of product authenticity and environmental conditions using a mobile device camera and blockchain technology. Consumers can independently verify product provenance, authentication codes, and sensor data without requiring specialized equipment or intermediaries, reducing the need for expensive centralized verification infrastructure.
Solution Approach 2:
The patent replaces complex mechanical authentication systems with optical-based blockchain verification. Instead of physical security features requiring specialized readers, the system uses optical images captured by standard mobile cameras to verify blockchain codes, significantly reducing hardware costs while maintaining or improving security.
3Reliability
If blockchain verification is performed with high security encryption, then authentication reliability improves, but computer resource requirements increase
Solution Approach 1:
Blockchain codes are pre-generated and embedded in the product during manufacturing, along with associated sensor data. This preliminary encoding allows for efficient verification later, as the mobile device only needs to compare captured images against pre-stored blockchain references rather than performing complex real-time cryptographic operations, reducing processing power requirements.
