Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic data sharing devices have security flaws, require pre-configuration, lack automatic detection capabilities, and restrict users in selecting shared information, leading to vulnerabilities and inconvenience in data exchange processes.
Innovation Solution
An electronic data sharing device that uses cryptographic tags for secure, wireless data exchange between devices, allowing users to share information without pre-configuration, with options for user-initiated or automatic synchronization, and enabling selective sharing of data, while ensuring privacy and security through encryption and unique device keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is exchanged between devices and later transmitted to a server, then contact information can be shared between users, but security vulnerabilities arise from third-party access and malware
Solution Approach 1:
The patent introduces a server as an intermediary that receives encrypted data from devices. The server acts as a secure mediator that stores and manages contact information without exposing it to unauthorized access, thereby resolving the security vulnerability while maintaining data sharing capability
Solution Approach 2:
The patent applies encryption to transform data from an unencrypted state to an encrypted state before transmission to the server. This parameter change (encryption) protects the data from third-party access and malware while allowing secure storage and retrieval
2Ease of operation
If users must enter contact details on the device prior to use, then data can be stored for exchange, but users face inconvenience if contact details change between entry and exchange
Solution Approach 1:
The patent performs data entry preliminarily by storing contact information on the device before exchange occurs. This preliminary action allows users to enter their contact details once, and the information remains available for multiple exchanges without requiring re-entry, while still allowing updates when needed
Solution Approach 2:
The patent makes the contact information dynamic by allowing users to update their contact details on the device at any time. The stored information can be modified without requiring device reconfiguration or reset, enabling flexibility while maintaining ease of use
3Productivity
If contact details are transferred to servers in an unencrypted format, then data can be accessed and shared, but third parties can gain unauthorized access to the data
Solution Approach 1:
The patent changes the encryption parameter by encrypting data before transmission to the server. This transformation maintains data accessibility through proper decryption while preventing unauthorized third-party access, thus resolving the contradiction between productivity and reliability
4Adaptability or versatility
If devices use electromagnetic coupling or infra-red beams for data exchange, then contact information can be transferred between devices, but devices cannot detect nearby devices automatically
Solution Approach 1:
The patent makes the device universal by implementing multiple communication methods (electromagnetic coupling, infra-red, and other wireless protocols). This multi-functionality enables both manual data exchange and automatic device detection, resolving the contradiction between adaptability and automation

AI summary
An electronic data sharing device for sharing user related information with users of other electronic data sharing devices, the electronic data sharing device comprising: a data exchange initiation device arranged to detect the initiation of a data exchange request; a tag generation module configured to generate a tag in preparation for the initiation of a data exchange routine, a communication module configured to exchange the tag generated on the electronic data sharing device with a tag generated by a further electronic data sharing device, wherein the exchanged tags enable user related information associated with respective users of the electronic data sharing devices to be subsequently accessed via a communication means by users who have previously initiated the data exchange request, wherein the electronic data sharing device is configured to exchange the tags in order to provide subsequent access to the user related information without requiring, before use of the device, any user related configuration or data entry associated with the device or service.
