Bluetooth Relay Locating for Offline Lost Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart electronic devices that are lost and offline cannot be located by servers, leading to poor user experience.
Innovation Solution
A method and apparatus that enables a network-disconnected electronic device to send a Bluetooth signal to another device, which scans and pairs via Bluetooth, sends a query request to a server, receives location information, and relays it back to the lost device for accurate offline locating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a touchscreen display is used without physical buttons, then the device structure is simplified and integration is improved, but operability deteriorates when the screen is wet or oily
Solution Approach 1:
The system performs preliminary detection of touch input validity by analyzing touch duration, pressure, and movement patterns before executing the intended function. This preliminary validation prevents erroneous inputs caused by accidental touches on wet or oily surfaces, thereby maintaining ease of operation while preserving the simplified touchscreen structure.
Solution Approach 2:
The system provides visual feedback through UI element changes (such as highlighting or dimming) to indicate whether a touch input is recognized as valid or invalid. This feedback mechanism helps users understand why certain touches are not responding, allowing them to adjust their interaction and maintain effective operability despite environmental conditions.
2Ease of operation
If the entire screen is made touch-sensitive, then ease of operation is improved, but false touches from water or oil increase
Solution Approach 1:
The system applies different touch sensitivity thresholds and validation rules to different regions or types of UI elements on the screen. Critical elements like confirmation buttons have higher validation requirements, while less critical areas have lower thresholds. This localized quality approach maintains high ease of operation for important functions while reducing false touches in vulnerable areas.
Solution Approach 2:
The system dynamically adjusts touch sensitivity parameters based on environmental conditions, usage context, and individual element characteristics. When water or oil contamination is detected through touch patterns, the system automatically increases validation strictness for subsequent touches, maintaining operational ease for legitimate inputs while filtering out false touches caused by contaminants.
3Object-affected harmful factors
If touch input validation is made more strict, then false touches are reduced, but legitimate touches may be rejected
Solution Approach 1:
The system applies partial validation to low-risk operations and excessive (strict) validation to high-risk operations. For example, navigation gestures may have simpler validation, while text input or confirmation actions have stricter validation. This differentiated approach reduces false touch rejection for routine operations while maintaining high false touch rejection for critical functions, preserving overall ease of operation.
Solution Approach 2:
The system changes validation parameters such as touch duration thresholds, pressure requirements, and movement velocity limits based on the specific operation being performed and environmental conditions. These dynamic parameter adjustments allow the system to maintain high false touch rejection when needed while ensuring legitimate touches are always accepted, balancing both objectives through adaptive parameter optimization.

AI summary
Embodiments of this application disclose an electronic device interaction method and a related apparatus. The method includes: pairing a first electronic device with a second electronic device through Bluetooth. The first electronic device is in a network-disconnected state. The second electronic device sends a query request to a server, to obtain a status of the first electronic device. The second electronic device sends the status of the first electronic device to the first electronic device. If the first electronic device is in a lost state, the first electronic device sends an offline locating request. The offline locating request indicates the second electronic device to send location information of the second electronic device to the server. According to embodiments of this application, an offline and lost device can be located. This can help a user find the lost device more quickly and accurately.
