Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The watch industry faces significant challenges in authenticating timepieces without modifying their appearance or requiring invasive procedures, as existing methods are not non-invasive and reliable enough to differentiate between genuine and counterfeit watches, especially since counterfeit watches can mimic the appearance and quality of authentic ones, leading to substantial financial losses.
Innovation Solution
A method and system that utilize external excitation to generate and analyze acoustic vibrations in timepieces, allowing for non-invasive authentication by measuring and processing the vibrations using microphones and signal processing techniques like Fourier transforms, enabling identification of the timepiece's material and structure without opening it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If marking methods (engraving, codes, materials) are used to authenticate timepieces, then authentication reliability is improved, but the visual appearance and design of the timepiece is compromised
Solution Approach 1:
The patent replaces mechanical/mark-based authentication systems with acoustic vibration analysis. Instead of using physical marks, engravings, or material markers that alter the timepiece appearance, the invention uses external excitation to generate acoustic vibrations and analyzes the resulting sound patterns. This substitution of mechanical marking with acoustic field-based detection resolves the contradiction by maintaining visual appearance while enabling reliable authentication through unique vibrational signatures.
2Reliability
If outer marks are used for authentication, then authentication capability is improved, but the marks are exposed to environmental factors (wear, dirt) and copying
Solution Approach 1:
The invention replaces vulnerable outer marks with internal acoustic vibration patterns that are inherent to the timepiece's structure and materials. These vibrational signatures cannot be easily copied or degraded by environmental factors like wear and dirt, as they emerge from the fundamental physical properties of the timepiece components rather than surface-level markings.
Solution Approach 2:
The timepiece itself generates the authentication signal through its natural acoustic vibrations when excited. The unique combination of materials, craftsmanship, and structural properties creates a self-identifying vibrational signature that requires no external markers or labels. This self-service approach eliminates the vulnerability of external marks while maintaining authentication capability.
3Measurement precision
If invasive procedures (opening the timepiece) are used to check authenticity, then authentication precision is improved, but the timepiece integrity and warranty are compromised
Solution Approach 1:
The patent replaces invasive mechanical inspection methods with non-contact acoustic vibration analysis. By using external excitation sources and microphones to capture and analyze the timepiece's vibrational response, the system achieves high authentication precision without physically opening or disassembling the timepiece. This preserves water tightness, structural integrity, and manufacturer warranties while still enabling detailed internal analysis.
4Ease of operation
If acoustic vibration analysis is used for authentication, then non-invasive authentication is achieved, but the ability to obtain information on inner content is limited
Solution Approach 1:
The invention uses mechanical vibration principles to extract internal structural information non-invasively. By applying external excitation and analyzing the resulting acoustic vibrations, the system can infer details about internal components, materials, and craftsmanship based on the unique vibrational signature. The vibrational patterns reveal information about the timepiece's inner content through resonance frequencies and damping characteristics without requiring physical access to internal components.
