3D Security Marking for Component Compatibility Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security markings fail to ensure the full compatibility and safety of connected components, as counterfeit parts can still be used despite detection, posing risks to users and device functionality.
Innovation Solution
Equipping at least one component with a three-dimensional security marking that changes shape in response to heat, magnetic fields, or external forces, allowing for active verification of compatibility through mechanical and optical means, and using this change to enable or disable device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical or magnetic security markings are used, then counterfeit products can be detected visually or magnetically, but the components can still be used in devices despite detection, failing to ensure full compatibility and safety
Solution Approach 1:
The security marking transitions from a static visual/magnetic indicator to a dynamic shape-changing element that responds to external stimuli (heat, magnetic fields, light). The three-dimensional piece changes its physical configuration based on the authenticity of the component, enabling active verification rather than passive detection.
Solution Approach 2:
The invention changes the physical state or shape of the security marking piece in response to external energy input. Genuine components exhibit specific shape changes (e.g., expansion, contraction, deformation) when exposed to heat, magnetic fields, or light, while counterfeit components do not replicate these parameter changes, providing a reliable differentiation mechanism.
2Reliability
If passive security markings are used, then manufacturing is simple and cost-effective, but active verification of component authenticity and compatibility cannot be performed
Solution Approach 1:
The security marking system is self-verifying through the intrinsic properties of the three-dimensional piece. When exposed to external energy (heat, magnetic field, light), the piece automatically changes shape based on its material composition and structural integrity, providing self-authentication without requiring complex external verification equipment.
Solution Approach 2:
The security marking utilizes composite or specialized materials (e.g., shape memory alloys, magnetically responsive materials, thermally responsive polymers) that exhibit specific shape-changing behaviors under external stimuli. These materials provide both the security function and the verification mechanism, integrating multiple functions into a single component.
3Reliability
If conventional two-dimensional security markings are used, then manufacturing precision requirements are low, but mechanical verification of component authenticity is not possible
Solution Approach 1:
The invention transitions from two-dimensional flat security markings to three-dimensional pieces with volumetric shape characteristics. This adds a spatial dimension to the security feature, enabling mechanical verification through shape changes in multiple directions and providing more complex authentication capabilities that are difficult to replicate in counterfeit components.

AI summary
Method for determining the mutual compatibility of components to be connected to each other, as well as new uses for memory-metal pieces. According to the invention, a first component is equipped with a three-dimensional metal-alloy piece, which is able to change its shape as a result of the effect of a voltage, an electric or magnetic field, heat or electromagnetic radiation, or a combination of these. A second component, to be connected to the first component, is equipped with an operating element, which is able to produce the desired energy effect, the first and second components are brought into the immediate vicinity of each other, and the operating element of the second component is used to direct an energy effect to the metal-alloy piece of the first component, in order to change the three-dimensional shape of the metal-alloy piece. The components are then determined to be compatible, if the change in shape of the metal-alloy piece exceeds a predefined limit value. By means of a security marking according to the invention, the genuineness of a product can be determined not only visually, but also with the aid of its operation or function, which the metal-alloy piece creates.
