Indicia Reading Terminal Battery Charging via Host Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indicia reading systems with wireless communication between terminals and cradles face limitations in battery charging performance, particularly when operating in various modes, due to limited power supply from host devices, which can lead to reduced battery life and inefficient operation.
Innovation Solution
The system is configured to charge the terminal's battery using power from the host device while operating in presentation mode, minimizing battery drain by optimizing power usage through reduced current consumption and auxiliary device integration, such as a bypass circuit, to maintain optimal battery levels during continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is implemented between terminal and cradle, then mobility and ease of operation are improved, but battery charging performance deteriorates due to limited power supply from host device
Solution Approach 1:
The system performs preliminary charging actions by detecting when the terminal is in presentation mode and automatically initiating battery charging from the host device power supply during that time, rather than waiting for the terminal to be returned to the cradle
Solution Approach 2:
The terminal monitors its own operational mode and autonomously manages its battery charging needs by utilizing power from the host device during presentation mode operation, without requiring external intervention or cradle docking
2Productivity
If terminal operates in presentation mode continuously, then productivity is improved, but battery charge level deteriorates due to power consumption
Solution Approach 1:
The system ensures continuous useful action by maintaining battery charging during presentation mode operation, allowing the terminal to operate continuously without interruption for recharging while maintaining productivity
Solution Approach 2:
The system uses feedback from detecting the terminal's operational mode to dynamically adjust power management, automatically charging the battery when presentation mode is detected and managing power consumption accordingly
