Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying and authenticating objects, especially small and inexpensive replaceable accessories, are costly and impractical due to the need for microcontrollers, which can increase product costs and are not feasible in all scenarios, such as when space or material constraints are limiting.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a microcontroller is embedded in each product for identification and authentication, then object identification and counterfeit detection capability is improved, but product cost significantly increases
Solution Approach 1:
The patent extracts the identification function from the expensive microcontroller and implements it using only a passive tag containing identification data. The active processing and authentication logic are moved to the main system, allowing the tag itself to be a simple, inexpensive component while still providing secure identification and counterfeit detection capabilities.
Solution Approach 2:
The patent uses a passive tag that contains identification data as a simplified copy of the full authentication system. Instead of embedding a complete microcontroller in each product, a lightweight replica containing only essential identification information is used, which can be read and verified by the main system without requiring full processing capabilities in the tag itself.
2Reliability
If a microcontroller is embedded in small spare parts for identification, then authentication capability is improved, but the device becomes too large or heavy for the application
Solution Approach 1:
The patent extracts the identification function from the heavy microcontroller and implements it using a lightweight passive tag. This allows small spare parts to maintain authentication capability while keeping weight and size constraints satisfied, as the passive tag contains minimal material compared to an active microcontroller.
3Reliability
If a microcontroller is embedded in small spare parts for identification, then authentication capability is improved, but available space for the component is insufficient
Solution Approach 1:
The patent extracts the identification function from the bulky microcontroller and implements it using a compact passive tag. This allows authentication capability to be maintained in small spare parts with limited space, as the passive tag occupies minimal volume compared to an active microcontroller with its required circuitry and power supply.
Solution Approach 2:
The patent uses a passive tag as a simplified copy of the authentication system, containing only essential identification data rather than full processing capabilities. This dramatically reduces the volume required while maintaining authentication functionality through verification by the main system.
4Ease of manufacture
If traditional identification methods are used for replaceable accessories, then manufacturing simplicity is maintained, but counterfeit detection capability is insufficient
Solution Approach 1:
The patent uses a passive tag containing identification data as a lightweight copy of the authentication system. This approach maintains manufacturing simplicity compared to embedding microcontrollers, while providing sufficient counterfeit detection capability through verification of the tag's identification data by the main system.

AI summary
A method is provided for identifying or authenticating an object. The method includes vibrating the object at a plurality of frequencies. The vibrations from the object are sensed at each of the plurality of frequencies using an accelerometer. A vibration profile of the object is generated using the sensed vibrations. The generated vibration profile is then compared to a stored vibration profile. It is determined if the generated vibration profile matches the stored vibration profile. A match indicates that the object has been identified or authenticated. In another embodiment, an object capable of implementing the method is provided. In another embodiment, the object may include a replaceable accessary. In this case, the initial and generated vibration profiles may be created with the replacement accessary attached to the object. A match of the generated and initial vibration profiles indicates that the replaceable accessary is authentic.
