Eyeglasses Identification Device in Decorative Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses with identification devices face challenges in maintaining aesthetic appeal while ensuring effective signal transmission between the identification device and external readers, and they often incur additional production costs.
Innovation Solution
The eyeglasses incorporate a decorative insert with an integrated identification device, where the device is positioned between the frame and the insert, utilizing a slot for data transmission, thus hiding the device from view while maintaining signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the identification device is integrated inside the frame or temple, then the authenticity verification and traceability are enabled, but the appearance of the eyeglasses is compromised and production costs increase
Solution Approach 1:
The identification device is extracted from the traditional locations (frame, temple, hinge) and repositioned to the decorative insert, which is a separate component. This allows the identification function to be separated from the main structural elements, preserving their appearance while maintaining functionality.
Solution Approach 2:
The decorative insert serves as an intermediary carrier for the identification device. It mediates between the need for authentication (housing the chip) and the need for aesthetic appearance (providing a decorative element that can conceal the chip). The slot in the insert acts as an intermediary channel for signal transmission without requiring external visibility of the device.
2Reliability
If the identification device is placed inside the frame, then authenticity verification is enabled, but additional production costs and machining steps are required
Solution Approach 1:
The identification device is merged with the decorative insert, which is already a required component for the aesthetic appearance of the eyeglasses. By combining the authentication function with an existing decorative element, no additional production steps or costs are incurred beyond what is already required for the decorative insert itself.
3Strength
If highly conductive materials are present near the identification device, then structural integrity is maintained, but signal transmission between the RFID device and external reader is impeded
Solution Approach 1:
The decorative insert is positioned such that the slot providing signal transmission access is located at a specific local position away from highly conductive metal parts of the frame. This creates a localized zone of electromagnetic compatibility while maintaining the overall structural integrity of the eyeglasses. The slot's position is strategically chosen to avoid interference from conductive materials.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for easy and correct reading of the identification device without compromising the eyeglasses' appearance, enhances signal transmission, and simplifies production by reducing the need for additional machining steps.
Implementation Method 1
The operation of a identification device is greatly influenced by the presence of highly conductive materials in its neighborhood since such materials impede, and can prevent, an effective communication between the RFID identification device and the external reader. In particular when a conductor, for example a metal, is immersed in an electromagnetic field, micro-currents are induced inside it
