Operating Mode Switching via Proximity and Short-Range Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often unintentionally switch to environmental operating modes when entering environments due to proximity-based wireless communication, and fail to switch back to initial modes when leaving, causing issues like missed calls or unintended mode changes.
Innovation Solution
An operating mode switching method that uses proximity-based wireless communication to switch to environmental modes and short-ranged wireless communication to automatically switch back to initial modes when environmental signals are no longer received, ensuring intentional mode changes and avoiding unintentional stays in environmental modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If proximity-based wireless communication is used to switch to environmental operating mode, then the device can automatically switch modes when entering an environment, but the device fails to switch back to initial mode when leaving, causing missed calls and operational errors
Solution Approach 1:
The patent implements a feedback mechanism where the device continuously monitors for environmental signals (NFC tags or Bluetooth signals) and adjusts its operating mode based on the presence or absence of these signals. When the environmental signal is no longer detected, the device automatically switches back to the initial operating mode, ensuring reliable and accurate mode transitions.
2Reliability
If short-ranged wireless communication is used to detect environmental signals, then the device can automatically switch back to initial mode, but the device may unintentionally switch modes when the user enters an environment without intent
Solution Approach 1:
The patent uses proximity-based wireless communication (NFC) to perform a preliminary action of switching to the environmental operating mode only when the user intentionally brings the device close to an NFC tag. This intentional proximity-based trigger prevents unintentional mode switching while allowing automatic switching back when the environmental signal is lost.
3Ease of operation
If the device requires intentional proximity-based communication to switch modes, then mode switching is intentional, but the user often forgets to switch back to initial mode when leaving the environment
Solution Approach 1:
The patent implements automatic feedback-based mode switching where the device continuously monitors for environmental signals and automatically switches back to the initial operating mode when the signal is no longer detected. This eliminates the need for users to manually remember to switch modes, preventing time loss and operational errors.

AI summary
An operating mode switching method for a electronic device is disclosed. The operating mode switching method includes receiving a notification message via a proximity-based wireless communication technology; switching from an initial operating mode to an environmental operating mode corresponding to the notification message; and switching from the target operating mode back to the initial operating mode when not effectively receiving an environmental signal corresponding to the notification message via a short-ranged wireless communication technology.
