Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in accurately determining their location and providing relevant services due to signal interference and the need to receive a list of transmitters in advance, leading to mismatched information and inadequate adaptive services based on distance and movement.
Innovation Solution
An electronic device equipped with a communication module, sensor, and processor that acquires identification information from external devices, detects movement, and selects appropriate service information based on location and movement conditions, transmitting this information to a server for personalized service provision without pre-receiving a list of transmitters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device receives a list of transmitters in advance, then service information can be provided through comparison, but data communication is performed unnecessarily and mismatch with actual information may occur due to time difference
Solution Approach 1:
The patent applies preliminary action by having the electronic device receive and store transmitter information in advance before actually needing it. The device pre-loads transmitter lists and stores them locally, so when the device enters a particular area, it can immediately compare its current location with the pre-stored transmitter information without needing to communicate with the server in real-time. This resolves the contradiction by performing the data reception action beforehand, reducing both the timing mismatch and unnecessary real-time communication.
2Measurement precision
If distance is detected simply based on signal strength, then the detection process is simple, but it is difficult to accurately determine distance due to signal interference and distortion
Solution Approach 1:
The patent introduces an intermediary approach by using multiple detection methods between simple signal strength measurement and complex multi-parameter analysis. The device uses signal strength as a preliminary indicator but combines it with transmitter list matching and comparison against pre-stored transmitter information. This intermediary method improves distance detection accuracy without requiring overly complex detection systems, as it leverages the existing transmitter database to validate and refine distance estimates.
3Loss of time
If the transmitter broadcasts a signal once for 1 to 10 seconds, then the transmission frequency is low, but the electronic device must wait to receive a plurality of signals
Solution Approach 1:
The patent applies preliminary action by pre-loading and storing transmitter information lists before the device actually needs to identify transmitters in a particular area. When the device enters an area, it can immediately compare its current transmitter detections with the pre-stored lists without waiting for multiple signal broadcasts or performing real-time server queries. This dramatically reduces waiting time and improves service response speed, as the comparison operation is performed locally and instantaneously against pre-fetched data.
4Adaptability or versatility
If the electronic device receives service information without considering movement, then the system is simple, but adaptive services for various movement cannot be provided
Solution Approach 1:
The patent applies dynamics by making the service information selection adaptive to the device's movement state. The system detects whether the device is moving or stationary and dynamically selects different service information based on this state. When moving, the device receives service information suitable for transit or passing through an area, while when stationary, it receives detailed service information appropriate for staying in the area. This dynamic adaptation increases versatility without requiring overly complex logic, as it uses a simple movement state detection to trigger different service modes.
