Innovation Solution
A software wireless device architecture that includes framework software with user interface, domain management, and hardware control components, which monitors the running status of hardware and software modules, detects abnormalities, and performs automatic recovery by restarting and resetting parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If framework software is used to install and manage wireless communication software, then the system can implement multiple wireless communication systems with flexible configuration, but there is no failure detection mechanism leading to system downtime when software failures occur
Solution Approach 1:
The patent implements a feedback mechanism where the interface service software continuously monitors the running status of framework software components (user interface software, domain management software, hardware management software, hardware control software) by issuing monitoring requests and detecting responses or abnormalities. When a failure is detected, the system automatically restarts the failed software, creating a closed-loop feedback system that maintains reliability while preserving configuration flexibility.
2Ease of manufacture
If distributed object technology is used to separate wireless communication software into modular components, then development and maintenance costs are reduced, but there is no clear definition for recovery when framework software abnormalities occur
Solution Approach 1:
The patent implements self-service recovery where the interface service software automatically detects abnormalities in framework software components and restarts the failed software without requiring manual intervention. The system autonomously issues monitoring requests, detects failures, and performs recovery actions, making the repair process self-service oriented while maintaining the modular architecture benefits.
3Adaptability or versatility
If software programs are downloaded from external sources to control hardware modules, then the wireless device can respond to multiple radio systems, but software failures cannot be detected after startup or operation
Solution Approach 1:
The patent implements continuous feedback monitoring where the interface service software periodically issues running status monitoring requests to framework software components and detects their responses. This active feedback mechanism enables real-time detection of software failures in downloaded programs, allowing the system to maintain adaptability for multiple radio systems while implementing reliable failure detection through continuous status monitoring.

AI summary
This software wireless device comprises framework software that installs wireless communication software; and interface service software that is provided so as to be directly managed by an OS, and that manages a user interface service and the framework software. The framework software has user interface software, domain management software, hardware management software, and hardware control software. The interface service software issues a running status monitoring request to the user interface software and the domain management software, and determines that there is an abnormality if there is no response from the user interface software or the domain management software.
