Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices face challenges in efficiently searching for and maintaining connections with Wi-Fi base stations while moving, leading to unstable communication and increased power consumption due to continuous searching.
Innovation Solution
Incorporating an acceleration sensor and control module that determines the device's status through detected acceleration patterns, allowing the communication module to selectively search for and connect to Wi-Fi base stations only when the device is in a staying state, thereby reducing unnecessary searches and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication module continuously searches for Wi-Fi base stations while moving, then connectivity availability is improved, but power consumption increases and communication stability deteriorates
Solution Approach 1:
The patent applies dynamics by making the base station search behavior adaptive to the device's movement state. The control module dynamically adjusts search behavior based on acceleration sensor input: when motion is detected, continuous searching is suspended; when stationary, searching resumes. This dynamic adjustment resolves the contradiction by optimizing power consumption during movement while maintaining connectivity reliability when stationary.
Solution Approach 2:
The patent implements periodic action through conditional base station searching. Instead of continuous searching, the system periodically initiates searches only when specific conditions are met (device is stationary, determined by acceleration sensor). This periodic approach reduces power consumption compared to continuous searching while maintaining adequate connectivity availability when the device is likely to remain in one location.
2Reliability
If the communication module continuously searches for Wi-Fi base stations, then connectivity availability is improved, but communication stability deteriorates due to instability while moving
Solution Approach 1:
The system dynamically adjusts search behavior based on real-time motion detection. When the acceleration sensor detects movement, the control module suspends base station searching to prevent unstable connections. When stationary, searching is enabled to ensure connectivity availability. This dynamic control simultaneously improves communication stability by avoiding searches during movement and maintains productivity by enabling searches when stationary.
3Adaptability or versatility
If base station searching is enabled during movement, then connectivity availability is improved, but unnecessary power consumption occurs
Solution Approach 1:
The patent applies preliminary action by checking the movement state via acceleration sensor before initiating base station searching. This preliminary check prevents unnecessary searching during movement, thereby avoiding energy waste. The system prepares to search only when the device is confirmed stationary, making the connectivity adaptation efficient and energy-conscious.
