Communication Device Pre-Startup Process for Reduced Startup Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices experience delays in starting communication due to the need for retransmission of start-up signals when the first communication unit fails to acquire a start-up command, leading to unnecessary power consumption and prolonged startup times for the second communication unit.
Innovation Solution
The communication device employs a pre-start-up process where the first communication unit initiates the startup of the second communication unit's constituents except the wireless unit upon receiving an external signal, ensuring the second unit is fully started only when a valid start-up command is received, thereby reducing startup time and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the first communication unit waits to confirm the start-up command before activating the second communication unit, then power consumption is reduced, but the startup time of the second communication unit increases
Solution Approach 1:
The first communication unit performs preliminary actions by pre-processing the external signal and preparing the control signal before the second communication unit is fully activated. This allows the second communication unit to start up faster while the first communication unit has already prepared the necessary activation commands, reducing the overall startup time without excessive power consumption.
Solution Approach 2:
The communication unit is divided into two distinct units: a first communication unit that operates continuously with low power consumption to monitor external signals, and a second communication unit that is activated only when needed. This segmentation allows the system to maintain low power consumption while enabling fast startup of the high-power second communication unit when required.
2Speed
If the first communication unit continuously monitors for start-up commands, then response time is improved, but power consumption increases
Solution Approach 1:
The system is segmented into a first communication unit designed for continuous low-power monitoring and a second communication unit for high-power communication tasks. This segmentation enables the first unit to maintain continuous operation with minimal power consumption while the second unit remains dormant until activation is required.
Solution Approach 2:
The first communication unit creates a control signal that is a processed copy of the external signal, which then activates the second communication unit. This copying mechanism allows the system to respond quickly to external commands while the first communication unit continues its low-power monitoring function.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the time required for the second communication unit to reach a full start-up state and minimizes power consumption by ensuring the high-power second communication unit is only activated when necessary, enhancing overall system efficiency.
