Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Valuable objects, such as gold jewelry, can be manipulated without external detection, requiring time-consuming and costly laboratory tests that may damage the item, making it difficult to verify authenticity and value.
Innovation Solution
A gold object with a protective layer containing a personalized, readable security code and additional security features, allowing for non-destructive identification and verification, using nanoparticles and secure database storage for unique code management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laboratory testing methods are used to detect manipulation, then manipulation can be detected, but the process is time-consuming and cost-intensive
Solution Approach 1:
A security code is integrated into the protective layer during manufacturing, enabling immediate verification without time-consuming laboratory tests. The code is embedded beforehand, allowing rapid authentication whenever needed.
Solution Approach 2:
Physical laboratory testing methods are replaced with optical/electronic reading of the security code. Instead of destructive material analysis, a non-contact or minimal-contact reading process verifies authenticity, dramatically reducing time and cost.
2Reliability
If destructive testing is used to detect manipulation, then manipulation can be detected, but the valuable item is destroyed or considerably damaged
Solution Approach 1:
Destructive physical testing is replaced by reading the security code embedded in the protective layer. This optical or electronic reading process detects manipulation without touching or damaging the valuable object, maintaining both reliability and object integrity.
Solution Approach 2:
The security code embedded in the protective layer serves as an intermediary that carries authentication information. Instead of testing the valuable object directly, the code is read to verify authenticity, eliminating the need for destructive sampling.
3Difficulty of detecting and measuring
If no security features are added, then the valuable object maintains its original appearance, but manipulation cannot be detected
Solution Approach 1:
The security code is nested within the protective layer that already surrounds the valuable object. This integration adds detection capability without requiring separate external components, minimizing additional complexity while maximizing security.
Solution Approach 2:
The security code function is merged with the protective layer structure. Instead of adding separate security components, the authentication feature is combined with the existing protective coating, reducing overall system complexity.
4Strength
If a protective layer is added to prevent wear, then surface protection is improved, but manipulation becomes externally imperceptible
Solution Approach 1:
The security code is embedded in the protective layer during manufacturing, before any potential manipulation occurs. This preliminary inclusion of authentication information enables future detection of tampering without affecting the protective function.
Solution Approach 2:
The protective layer has different local properties: it provides uniform wear protection across the surface, while containing a specific local security code feature that enables manipulation detection. This local differentiation resolves the contradiction between protection and detectability.
