Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face limited battery life due to high power consumption while continuously searching for access points, especially when not in use, leading to inefficient power management.
Innovation Solution
The device deactivates components responsible for searching for access points until a message transmission is imminent, activating them only when necessary to conserve power and extend battery life.

Engineering Contradiction Analysis
1Reliability
If the device continuously searches for access points, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The device transitions from continuous searching to periodic searching, where the search function is activated at specific intervals or under specific conditions (such as when motion is detected or when a timer expires). This periodic operation maintains the ability to detect access points while significantly reducing the average power consumption compared to continuous operation.
Solution Approach 2:
The search function is made dynamic by adjusting its activation state based on device state (active/idle), detected motion, or communication needs. The system dynamically switches between active searching and dormant states, optimizing the balance between maintaining communication reliability and conserving battery power based on real-time conditions.
2Duration of action of moving object
If components are deactivated to conserve power, then battery life is extended, but response time increases
Solution Approach 1:
The device performs preliminary actions by keeping the search function in a low-power standby state where it can be quickly activated. Motion sensors or timers detect conditions that may require communication, and the search function is activated in advance or immediately when needed, reducing the actual response time while maintaining extended battery life through periodic deactivation.
Solution Approach 2:
The system uses feedback from motion sensors, communication status, and timing mechanisms to dynamically control component activation. When feedback indicates that communication may be needed (motion detected, timer expired, or communication request received), the system activates the search function, ensuring rapid response while minimizing overall power consumption through intelligent control.
