Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear frames with embedded electronic devices face challenges in synchronizing the devices within the same frame, particularly when using radio waves, which can lead to pairing errors with different frames, and require complex synchronization procedures.
Innovation Solution
The eyewear frame incorporates a wireless communication system, specifically close-range communication systems like NFC, to synchronize electronic devices in the temples when brought into contact or quasi-contact, with activation mechanisms such as motion patterns or battery charging, ensuring secure and simple synchronization without external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio waves are used for wireless communication between electronic devices, then communication flexibility is improved, but pairing accuracy deteriorates due to interference from other frames
Solution Approach 1:
The patent segments the communication process into two distinct phases: a close-range pairing phase using NFC technology for accurate device matching, and a subsequent medium-range communication phase using radio waves for data exchange. This segmentation allows each communication mode to operate in its optimal range, with NFC ensuring precise pairing between left and right temple devices of the same frame before radio wave communication begins.
Solution Approach 2:
The patent introduces NFC technology as an intermediary mechanism that facilitates accurate pairing between electronic devices. The NFC system acts as a mediator that establishes initial contact and verifies device identities before enabling radio wave communication, thereby preventing incorrect pairing between frames while maintaining wireless communication flexibility.
2Manufacturing precision
If close-range communication systems are used for synchronization, then pairing accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional communication architecture where electronic devices are equipped with both NFC and radio wave communication capabilities. The NFC system serves multiple purposes: initial device discovery, pairing verification, and triggering the radio wave communication system. This universal approach allows a single integrated system to handle both close-range pairing and medium-range data exchange, reducing overall system complexity despite incorporating multiple communication technologies.
3Adaptability or versatility
If synchronization is performed during temple replacement, then adaptability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by activating the close-range NFC communication system only at specific moments when temple replacement or device reconfiguration is detected through motion sensors. The system remains dormant during normal operation and activates only when needed, such as when the temple is removed or reattached, thereby enabling adaptability for temple replacement while minimizing power consumption by avoiding continuous communication.
