Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile electronic device continuously performs wireless signal searching procedure, then the network connection availability is improved, but the power consumption is increased
Solution Approach 1:
The patent applies dynamics by making the signal searching frequency adjustable rather than fixed. The system dynamically changes the searching frequency based on motion status detection, transitioning between high-frequency searching when moving and low-frequency searching when stationary, thereby adapting the energy consumption to actual network needs
Solution Approach 2:
The patent implements feedback through motion sensors that continuously monitor device movement and provide information to the control unit. This feedback loop enables the system to automatically adjust searching behavior based on real-time motion status, reducing unnecessary searches when the device is stationary in poor reception areas
2Use of energy by moving object
If the motion sensor is activated to determine motion status, then the power consumption is reduced by avoiding unnecessary searches, but the device complexity is increased
Solution Approach 1:
The patent applies universality by utilizing the motion sensor's capability for multiple purposes. The motion sensor not only detects device movement for searching frequency adjustment but can also serve other device functions, amortizing the complexity cost across multiple uses and making the added component more justifiable

AI summary
A method for searching wireless signal, a mobile electronic device using the same, and a non-transitory storage medium are provided. In the method, after a motion sensor of the mobile electronic device is activated, a motion status of the mobile electronic device is determined by using the motion sensor. Then, a frequency of the mobile electronic device performing a wireless signal searching procedure is adjusted according to the motion status, so as to reduce power wasted due to the unnecessary wireless signal searching procedure being performed.
