Dynamic RF Power Adjustment for Detachable Tablet Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In detachable notebook computers, the continuous variation in the relative position between the tablet and keyboard leads to excessive power consumption in wireless communication chips due to non-adaptive RF power settings, reducing battery life.
Innovation Solution
A control method and electronic device that detect the positional relation between the first and second bodies, determine the distance parameter between communication units, and adjust their power accordingly to ensure optimal communication while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF power is set to maximum to ensure transmission quality for any position, then communication reliability is improved, but power consumption increases excessively
Solution Approach 1:
The patent implements dynamic RF power adjustment by continuously monitoring the relative position between tablet and keyboard and adapting transmission power accordingly. The system transitions from static maximum power setting to dynamic power control that matches actual communication needs, resolving the contradiction between maintaining reliable transmission and reducing unnecessary power consumption.
Solution Approach 2:
The patent changes the RF power parameter based on detected positional relationships. By calculating distance and orientation between communication units and adjusting transmission power as a variable parameter rather than a fixed maximum value, the system achieves both reliable communication and reduced power consumption.
2Adaptability or versatility
If the tablet is rotated around the keyboard, then usability and display flexibility are improved, but the distance between wireless chips varies continuously requiring higher power
Solution Approach 1:
The patent employs feedback mechanisms where sensors continuously detect the relative position between tablet and keyboard, this positional information is fed back to the communication control system which then adjusts RF power accordingly. This closed-loop feedback system enables the device to maintain communication quality across various rotated positions without excessive power consumption.
Solution Approach 2:
The system dynamically adapts communication parameters to match the dynamic rotational movements of the tablet. By making the power setting a dynamic variable that responds to positional changes rather than a static maximum, the system supports display flexibility while avoiding unnecessary power consumption during rotation.
