Wireless Network State Feedback for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices with wireless LAN capabilities may inadvertently turn off the wireless network, leading to confusion between device malfunction and intentional disconnection, especially in sensitive environments where wireless interference can cause critical issues.
Innovation Solution
A wireless communicating electronic device with an on/off selector, a display to show the wireless network state, and a controller that activates or deactivates the wireless network based on user input and displays the state, using visual indicators like LEDs to inform the user of the network's status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an on/off button or function key is installed to control wireless LAN, then wireless communication can be turned off to prevent interference with electronic equipment, but users may mistakenly think the wireless LAN is malfunctioning when they turn it off intentionally
Solution Approach 1:
The patent applies feedback by implementing a display that continuously shows the current state of the wireless network (on/off status) to the user. This visual feedback mechanism ensures users are aware when they have turned off the wireless LAN, preventing the misconception that the system is malfunctioning. The display provides real-time information about the network state, creating a closed-loop communication between the system state and user perception.
Solution Approach 2:
The patent introduces an intermediary element (the display device) between the wireless network control mechanism and the user. This intermediary translates the internal system state (network on/off status) into visible information that users can perceive, thereby bridging the gap between system operation and user awareness without requiring users to understand technical details.
2Reliability
If wireless LAN is turned off to comply with regulations in sensitive environments, then interference with electronic equipment is prevented, but users lose the ability to use wireless communication when needed
Solution Approach 1:
The patent applies dynamics by making the wireless network state changeable and controllable by the user through the on/off button, with the display dynamically updating to reflect the current state. This dynamic system allows the wireless LAN to be turned off for compliance in sensitive environments, yet can be easily turned back on when users need wireless communication, providing adaptability to different operational contexts and user needs.
