Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic data sharing devices have security flaws, require pre-configuration, lack automatic detection of nearby devices, and restrict selective information sharing, leading to limitations in usability and privacy concerns.
Innovation Solution
An electronic data sharing device that uses a unique tag generation system for secure, proximity-based data exchange without pre-configuration, enabling users to share information without revealing personal details until a match is confirmed on a server, and includes features for automatic detection of nearby devices using radio communication and low-power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices exchange data via electromagnetic coupling or infra-red beams requiring close proximity and alignment, then data exchange can occur between devices, but users cannot detect nearby devices automatically and must manually align devices
Solution Approach 1:
The patent introduces radio frequency (RF) signals as an intermediary medium for device detection. Instead of requiring direct electromagnetic coupling or optical alignment between devices, the RF intermediary allows devices to broadcast and detect the presence of other devices wirelessly without precise alignment, enabling automatic detection while maintaining security through controlled data exchange protocols
2Productivity
If devices store and exchange contact details locally without pre-configuration, then users can exchange information quickly, but security vulnerabilities arise from unencrypted data transmission and lack of verification
Solution Approach 1:
The patent implements preliminary actions by pre-configuring devices with unique identification tags and establishing secure communication protocols before actual data exchange occurs. This allows rapid exchange of contact information while maintaining security through pre-verified encryption keys and authentication mechanisms that are already in place before the exchange happens
Solution Approach 2:
The patent uses encrypted copying of data between devices rather than direct unencrypted transmission. Contact information is copied from one device to another through secure protocols that verify the receiving device's authenticity, ensuring that data is replicated safely without exposing it to interception or unauthorized access
3Adaptability or versatility
If devices require users to enter contact details before use, then data can be exchanged, but users cannot share information if details change between entry and exchange
Solution Approach 1:
The patent enables devices to automatically update and synchronize contact information without requiring manual re-entry by users. The system self-updates contact details stored on devices, allowing users to exchange current information dynamically. This self-service mechanism maintains accuracy while eliminating the burden of manual configuration updates
4Ease of operation
If devices transmit data to servers in unencrypted format for web access, then users can access exchanged information via web pages, but third parties can access and compromise the data
Solution Approach 1:
The patent transmits only encrypted copies or references of contact information to servers rather than full unencrypted data. This allows web-based access and sharing functionality while maintaining security through encryption. The server stores and manages encrypted data copies, enabling web access without exposing plaintext information to third parties or compromising user privacy

AI summary
An electronic data sharing device for sharing user related information with users of other functionally similar electronic data sharing devices, the electronic data sharing device configured to: generate a temporary, non-unique, identification tag to identify the electronic data sharing device, transmit from the electronic data sharing device the generated identification tag via a wireless medium, receive at the electronic data sharing device a further identification tag generated by a further electronic data sharing device, and generate an alert on the electronic data sharing device when the transmission and reception of the identification tags coincide to indicate that the further electronic data sharing device is in the vicinity.
