Central Management Unit for Mobile Terminal Environmental Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing information to mobile terminals in communication networks require equipping devices with sensing capabilities or manual profile creation, and users must actively indicate their location to receive relevant information, which is inefficient and limited in providing timely and user-specific environmental data.
Innovation Solution
A central management unit connected to a database of environmental information retrieves location-specific data and compares it to user-defined profiles, transmitting alerts only when conditions exceed or drop below set threshold values, allowing for real-time, user-specific information delivery to mobile terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal is equipped with sensing devices to obtain environmental information, then the information can be obtained directly at the mobile device, but the device complexity and cost increase
Solution Approach 1:
The sensing function is extracted from the mobile terminal and relocated to fixed environmental monitoring stations. The mobile terminal only needs to receive and display information, not generate it through sensors. This resolves the contradiction by maintaining information availability while eliminating the need for complex sensing devices in the mobile terminal.
Solution Approach 2:
A network system acts as an intermediary between environmental sensors and the mobile terminal. Sensors at fixed locations transmit data through the network to the mobile device, eliminating the need for the mobile terminal to have its own sensors while maintaining real-time information availability.
2Reliability
If the user manually indicates their location to obtain environmental information, then the information can be provided, but the ease of operation decreases and time is lost
Solution Approach 1:
The system automatically determines the mobile terminal's location using network-based positioning (cell tower triangulation, GPS) without requiring user input. The terminal self-identifies its location, and the system automatically retrieves and provides relevant environmental information, eliminating manual location indication while maintaining accuracy.
Solution Approach 2:
The system continuously tracks and stores the mobile terminal's location information in advance, so when environmental data is requested, the location is already known and information can be immediately provided without requiring the user to manually indicate their position.
3Speed
If environmental information is continuously transmitted to the mobile terminal, then the user receives timely updates, but the quantity of information increases causing unnecessary messages
Solution Approach 1:
The system changes the parameter of information transmission from continuous to event-driven, sending data only when environmental parameters exceed or fall below user-defined thresholds. This maintains timely notification of critical changes while dramatically reducing the quantity of unnecessary information transmitted during normal conditions.
Solution Approach 2:
Instead of transmitting all environmental data continuously, the system selectively transmits only the specific information that exceeds user-defined thresholds or is currently relevant to the user's location and profile, providing sufficient information for decision-making without overwhelming the user with excessive data.
4Ease of operation
If generic environmental information is provided to all users, then the system is simple to operate, but the adaptability to individual user needs decreases
Solution Approach 1:
The system implements user-specific profiles with personalized thresholds, preferred information types, and location preferences. Each user receives environmental information tailored to their individual needs and concerns, such as different pollution thresholds for asthma patients versus general users, while the underlying system remains operationally simple through automated profile management.
