Wearable Optical Signal Transmitter for Identity Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In social interactions, individuals often face difficulties in managing and exchanging identity information, such as names and contact details, due to forgetfulness, loss of business cards, or shyness, especially in casual meetings where physical presence is key but information retrieval is cumbersome.
Innovation Solution
A portable social client system that includes a wearable device with a memory to store identity information, an encoder to associate this information with an optical signal pattern, and an optical signal transmitter to broadcast this pattern, allowing for semi- or fully-automatic, unobtrusive, and secure exchange of identity information using non-visible light spectra.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical signal transmission is used to exchange identity information, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent uses optical signals as an intermediary medium to transmit identity information between devices. The optical signal transmitter converts electrical signals representing identity information into optical signals that can be wirelessly transmitted through air, serving as a mediator that bridges the gap between digital data storage and wireless communication without requiring direct electromagnetic coupling between devices.
Solution Approach 2:
The patent replaces traditional mechanical or direct electrical contact methods for information exchange with optical signal transmission. Instead of requiring physical connection or near-field electromagnetic coupling, the system uses light-based communication that allows devices to exchange identity information wirelessly through air, simplifying the interaction mechanism.
2Object-affected harmful factors
If non-visible light spectrum is used for optical signal transmission, then the object-affected harmful factors are reduced, but the measurement precision deteriorates
Solution Approach 1:
The patent employs optical filters that selectively transmit specific wavelengths of light while blocking others, analogous to porous materials that selectively allow certain molecules to pass through. The receiver includes filters tuned to the specific wavelength or wavelength range used by the transmitter, allowing the desired optical signal to pass through while blocking visible light and other unwanted wavelengths, thus reducing interference without compromising signal detection.
Solution Approach 2:
The patent changes the wavelength parameter of the optical signal from visible light to non-visible light (infrared or ultraviolet). This parameter change shifts the signal into a spectrum region with less ambient interference from visible light sources, while the receiver is specifically designed with sensors and filters optimized for detecting signals at these altered wavelengths, maintaining measurement precision despite the parameter change.
