Portable Device Contextual Control via Wireless ID Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face safety and convenience issues with portable devices, such as cell phones, as they often inadvertently use SMS programs while driving or in inappropriate settings, leading to accidents or disturbances, due to lack of automatic control over device functions based on location or context.
Innovation Solution
An electronic system and method that includes a first wireless transceiving module with a device identification code and a portable device equipped with a second wireless transceiving module, storage module, and processor, which communicates to obtain the device identification code and automatically executes pre-assigned instructions when the code matches a pre-built identification code, enabling or disabling device functions such as SMS programs based on location or context, such as disabling SMS while driving or muting in a cinema.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic control of device functions based on location or context is implemented, then user convenience and safety are improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-storing multiple identification codes and corresponding control instructions in the portable device. When the portable device detects a match between a transmitted identification code and stored codes, it automatically executes the corresponding instruction (such as disabling SMS or adjusting volume) without requiring user intervention. This preliminary preparation of code-instruction pairs enables automatic contextual control while maintaining relatively simple system architecture.
2Speed
If wireless communication modules are continuously activated to detect identification codes, then response speed is improved, but power consumption increases
Solution Approach 1:
The wireless communication module in the portable device operates periodically rather than continuously. It activates to receive and match identification codes at intervals, comparing received codes against pre-stored codes. This periodic operation maintains adequate response capability for contextual detection while significantly reducing power consumption compared to continuous activation, as the module can enter low-power states between detection cycles.

AI summary
An electronic system includes a first wireless transceiving module having a device identification code and a portable device. The portable device may include a second wireless transceiving module, and a processor. The second wireless transceiving module obtains the device identification code from the first wireless transceiving module. When the second wireless transceiving module obtains the device identification code from the first wireless transceiving module, the processor checks whether the device identification code matches to a pre-built identification code; and when the device identification code matches to the pre-built identification code, the portable device automatically determines a position of the portable device, and displays a map related to the position of the portable device in a display.
