Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for exchanging data, such as contact and communication data, between mobile phones and landline telephones are inefficient, requiring manual entry or dual data management, and are prone to misuse due to shared usage in offices and conference rooms.
Innovation Solution
Equipping both devices with NFC technology for secure data synchronization, using RFID for authentication and Bluetooth for data transmission, with secure coupling and certificate-based authentication to ensure secure data exchange and automatic call forwarding when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is saved on both mobile phone and landline telephone, then data availability is improved, but data management complexity and storage requirements increase
Solution Approach 1:
The patent introduces a server as an intermediary that centralizes data storage and management. The mobile phone and landline telephone both access data through this server, eliminating the need for duplicate local storage. This resolves the contradiction by maintaining data availability through centralized access while reducing data management complexity and storage requirements at individual devices.
2Adaptability or versatility
If landline telephone is used by multiple people, then device utilization is improved, but data security and access control worsen
Solution Approach 1:
The patent implements user-specific data profiles and access control lists that associate different data sets with different users. When multiple people use the same landline telephone, each user's data remains locally quality-controlled through their unique profile, ensuring data security is maintained despite high device utilization. The system selectively provides access based on user identity and permissions.
3Device complexity
If manual data entry is used, then device complexity is reduced, but time consumption and productivity worsen
Solution Approach 1:
The patent implements automatic data synchronization where the system itself performs data exchange between mobile phone and landline telephone without requiring manual intervention. Data is automatically uploaded to and downloaded from the server based on change detection, eliminating time-consuming manual entry while maintaining system simplicity through standardized communication protocols.
4Ease of operation
If NFC technology is used for authentication and data transfer, then connection speed and ease of operation are improved, but device complexity and security requirements increase
Solution Approach 1:
The patent pre-configures NFC tags with authentication credentials and device identifiers before actual use. When users bring devices close together, the authentication process is already prepared and can execute automatically or with minimal user input. This preliminary preparation maintains ease of operation during actual connection while managing authentication complexity through advance setup.
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
Facilitates seamless and secure transfer of data like phone numbers, address books, and calendars between devices, ensuring secure access and minimizing data exposure to unauthorized users, while allowing easy reconnection and secure handling in various environments.
Implementation Method 1
an RFID reader installed in a landline telephone, for example, generates a high-frequency electromagnetic alternating field, which reaches the antenna of an RFID tag arranged in a mobile phone, for example. In the case of an inductively operated RFID tag, an induction current is generated in the antenna coil as soon as it enters the electromagnetic field.

AI summary
The invention relates to a method for exchanging data between a mobile telephone and a fixed line telephone. According to the invention, a mobile telephone equipped with Near Field Communication (NFC) technology and a fixed line telephone that is also equipped with NFC technology are initially placed in a reception range, subsequently the mobile telephone and the fixed line telephone are coupled by means of the NFC technology, and then data is transmitted between the mobile telephone and the fixed line telephone by means of the NFC technology. Said coupling occurs when the mobile telephone and the fixed line telephone are authenticated, and two different NFC technologies are used for the authentication of the mobile telephone and the fixed line telephone, and the subsequent transmission of data.
