Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phones face challenges in maintaining wireless network connections due to signal interference and the need for manual configuration changes when switching access points, leading to frequent disconnections and battery drain during reconnection attempts.
Innovation Solution
A mobile phone with a storage device and controller that stores multiple configuration groups of wireless network files, allowing automatic selection and switching between them to establish and reestablish connections, prioritizing signal strength and configuration settings to maintain connectivity without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple configuration groups are stored and automatically switched between them, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments wireless network configuration files into three distinct groups (first, second, and third configuration groups) stored in the memory device. Each group contains configuration files for different access points or network conditions. This segmentation allows the system to systematically try different configuration groups when connection failures occur, improving reliability without requiring complete reconfiguration. The controller selectively accesses specific groups based on connection status, managing complexity through organized structure.
Solution Approach 2:
The patent implements preliminary action by pre-storing multiple configuration groups in the memory device before connection attempts. When a wireless connection fails, the controller automatically selects and applies the next configuration group without requiring manual user input. This preliminary preparation of multiple configuration options enables rapid automatic reconnection, improving reliability while the automated selection process manages the complexity of having multiple configurations.
2Reliability
If automatic reconnection attempts are made without evaluation, then connection reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements feedback mechanisms where the controller evaluates connection status before initiating reconnection attempts. The system monitors whether a wireless connection is established and only triggers automatic reconnection when disconnection is detected. This feedback-based approach prevents unnecessary reconnection attempts, managing energy consumption while maintaining connection reliability through targeted automatic reconnection only when needed.
Solution Approach 2:
The patent applies partial action by implementing limited automatic reconnection attempts rather than continuous or excessive retrying. The controller tries to establish connection using configuration files from the first configuration group, and only proceeds to second or third groups if initial attempts fail. This partial approach to reconnection (trying multiple configuration groups sequentially rather than indefinitely) maintains reliability while avoiding excessive energy consumption from futile connection attempts.
3Device complexity
If manual configuration reset is required for each access point, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service functionality where the mobile phone automatically selects and applies appropriate configuration files from stored groups without requiring manual user intervention. When a wireless connection is needed, the controller automatically attempts to establish connection using configuration files, and if disconnection occurs, automatically tries alternative configuration groups. This self-service capability significantly improves ease of operation, allowing users to connect to different access points without manually resetting configurations.
Solution Approach 2:
The patent creates a universal configuration management system that handles multiple access points and network conditions through a single automated mechanism. The controller is designed to work with multiple configuration groups, automatically selecting appropriate configurations based on connection status. This multi-functional approach improves ease of operation by providing a unified automatic connection management system that works across different access points and network conditions, rather than requiring separate manual configuration procedures for each scenario.

AI summary
A mobile phone is provided. A wireless connection module establishes a wireless connection between the mobile phone and an access point. A storage device stores a first configuration group, a second configuration group, and a third configuration group, each comprising at least one wireless network configuration file. A controller, when a wireless network function of the mobile phone is activated, selects the wireless network configuration file from the first configuration group, when failing to establish a wireless connection based on the wireless network configuration file selected from the first configuration group, selects the wireless network configuration file from the second configuration group, when failing to establish a wireless connection based on the wireless network configuration file selected from the second configuration group, selects the wireless network configuration file from the third configuration group, and establishes the wireless connection according to the selected wireless network configuration file.
