Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without direct internet connectivity or suitable user interfaces face challenges in unlocking functions, requiring cumbersome multi-step processes that are error-prone and difficult for non-experts to understand.
Innovation Solution
Utilizing an NFC interface as a second communication link between an intermediate device and a device, allowing for secure, physical authentication and enabling function unlocking without additional communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices use direct internet connectivity and standard communication interfaces for unlocking functions, then the unlocking process can be automated and efficient, but devices without internet connectivity or suitable user interfaces cannot be unlocked
Solution Approach 1:
The patent introduces an intermediate device (such as a smartphone) that acts as a mediator between the target device and the unlocking server. The intermediate device establishes a temporary communication bridge, allowing activation data to be transferred to devices that lack direct internet connectivity or suitable user interfaces. This resolves the contradiction by enabling universal device compatibility while keeping the unlocking process simple for end users.
2Reliability
If multiple communication channels are used for unlocking, then reliability can be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent employs dynamic communication channel selection where the system automatically chooses the most appropriate communication path based on device capabilities and availability. The intermediate device can switch between different communication protocols (NFC, Bluetooth, Wi-Fi) as needed, providing reliable unlocking without requiring the target device to have complex fixed communication infrastructure.
3Ease of operation
If standard license key activation is used, then the process is simple for connected devices, but security is compromised for devices without direct connectivity
Solution Approach 1:
The system performs preliminary authentication and validation through the intermediate device before final activation. The unlocking server verifies the license key and generates activation data in advance, which is then securely transmitted through the intermediate device to the target device. This preliminary action ensures security is maintained while keeping the final activation step simple for users.
