Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers driven by batteries face challenges in maintaining sufficient power delivery as the battery charge fluctuates, potentially leading to insufficient power for printing operations.
Innovation Solution
A printer configuration that includes a printing unit, power delivery unit, processor, and memory to monitor and adjust output power based on the remaining battery charge, using a power data object (PDO) to categorize and manage power delivery accordingly, ensuring continuous power supply for printing.

Engineering Contradiction Analysis
1Power
If the power transmission device delivers output power to the power reception device based on initial battery power, then the power delivery can start immediately with sufficient power, but the power necessary for the power transmission device itself may become insufficient when the remaining charge decreases
Solution Approach 1:
The patent applies dynamics by making the output power adjustable rather than fixed. The power transmission device dynamically changes the output power delivered to the external device based on real-time monitoring of battery remaining charge. When remaining charge is high, higher output power is provided; when remaining charge decreases, the output power is reduced to ensure sufficient power remains for the power transmission device's own operations.
Solution Approach 2:
The patent implements feedback by continuously monitoring the battery's remaining charge and using this information to adjust the output power delivery. The power transmission device receives feedback about the current charge state and modifies its power delivery accordingly, creating a closed-loop control system that adapts to changing battery conditions.
2Reliability
If the printer monitors and adjusts output power based on remaining battery charge, then the necessary power for printing can be secured, but the device complexity increases due to monitoring and control mechanisms
Solution Approach 1:
The patent applies self-service by enabling the power transmission device to automatically monitor its own battery charge state and autonomously adjust its output power without external intervention. The device manages its own power resources by detecting remaining charge levels and independently making decisions about power delivery adjustments, reducing the need for complex external control systems.
