Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices fail to provide application information, such as weather updates, that are tailored to a user's current activity state, as they rely on predetermined or manual update schedules rather than real-time user context.
Innovation Solution
An electronic device that identifies a user's activity state through sensor information and updates weather information accordingly, using a processor to synchronize with positioning and wireless communication circuits to display relevant graphic objects on a touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If weather information is updated at predetermined intervals or manually, then the update mechanism is simple and energy-efficient, but the information cannot be tailored to the user's current activity state
Solution Approach 1:
The system continuously monitors sensor data (accelerometer, gyroscope, barometer) to detect user activity states and uses this feedback to dynamically adjust the weather information update frequency. When the user is detected to be in motion, the system increases update frequency; when stationary, it reduces frequency. This closed-loop feedback mechanism enables adaptability without requiring complex manual configuration.
Solution Approach 2:
The system automatically determines the appropriate update frequency based on sensor-derived activity states without requiring user intervention. The processor autonomously adjusts the update period according to detected motion patterns, eliminating the need for manual update scheduling while adapting to user needs.
2Loss of information
If weather information is updated frequently to match user activity state, then information relevance is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the weather information update frequency based on real-time activity state detection. When the user is stationary, updates occur at lower frequency to conserve energy; when the user is in motion, the system increases update frequency to maintain information relevance. This dynamic adjustment optimizes the balance between information freshness and energy consumption.
Solution Approach 2:
The system changes the update period parameter based on detected activity state. The processor modifies the time interval between weather information updates according to motion detection results, using longer intervals during low-activity periods and shorter intervals during high-activity periods, thereby adapting energy consumption to actual user needs.
3Productivity
If the system continuously monitors sensor information to identify activity state, then real-time adaptability is achieved, but processing complexity and power usage increase
Solution Approach 1:
The system processes sensor data at different levels of intensity based on activity state. During low-activity periods, monitoring frequency is reduced to minimize processing overhead. During high-activity periods or when state changes are detected, the system intensifies monitoring and processing. This partial action approach maintains responsiveness while reducing average processing complexity.
Solution Approach 2:
The system employs periodic sensor sampling with variable intervals rather than continuous monitoring. The sampling frequency is adjusted based on detected activity patterns, with longer intervals during stable low-activity states and shorter intervals when changes are detected. This periodic approach reduces processing complexity while maintaining the ability to detect activity state changes.
