Solution Overview
Problem
Existing battery-powered printers face challenges in accurately determining battery exhaustion without operator input, particularly when using multiple types of batteries, as uniform threshold settings can lead to over-discharge or under-discharge issues due to differing voltage characteristics between primary and secondary batteries.
Innovation Solution
A printer system that automatically adjusts threshold values for battery exhaustion determination based on the type of battery used, employing a voltage detecting device and a control system to switch between threshold settings corresponding to the specific voltage characteristics of primary and secondary batteries, preventing over-discharge and ensuring battery utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a uniform threshold value is set for battery exhaustion determination, then the device can operate with simple control logic, but the battery type cannot be properly accommodated leading to over-discharge or under-discharge issues
Solution Approach 1:
The patent applies parameter changes by switching between different threshold values based on the detected battery type. The control unit changes the threshold parameter from a first threshold (for primary batteries) to a second threshold (for secondary batteries) according to the battery characteristics detected through voltage drop measurements, thereby optimizing exhaustion determination accuracy for each battery type without requiring complex manual configuration
Solution Approach 2:
The patent implements self-service by enabling the printer to automatically detect battery type and adjust threshold values without operator intervention. The control unit autonomously measures voltage drops during printing operations, identifies whether a primary or secondary battery is installed, and self-adjusts the exhaustion threshold accordingly, eliminating the need for manual battery type input or complex user configuration
2Duration of action of moving object
If the threshold value is set according to primary battery characteristics, then primary batteries can be fully utilized, but secondary batteries may be over-discharged
Solution Approach 1:
The patent changes the threshold parameter dynamically based on battery type detection. When a primary battery is detected (through voltage drop characteristics), the first threshold value is applied to maximize utilization. When a secondary battery is detected, the second threshold value is applied to prevent over-discharge, thereby protecting secondary batteries from harmful over-discharge while fully utilizing primary batteries
3Object-affected harmful factors
If the threshold value is set according to secondary battery characteristics, then secondary batteries are protected from over-discharge, but primary batteries cannot be fully utilized
Solution Approach 1:
The patent dynamically adjusts the threshold parameter based on the detected battery type. For secondary batteries, the second threshold value is applied to prevent over-discharge and protect battery health. For primary batteries, the first threshold value is applied to enable full utilization until complete exhaustion, thereby optimizing both protection and utilization according to battery type
4Adaptability or versatility
If automatic battery type detection is implemented, then the device can adapt to different battery types, but the detection accuracy may be insufficient leading to false identification
Solution Approach 1:
The patent employs dynamic measurement by conducting voltage drop detection during actual printing operations rather than static measurements. The control unit measures voltage drops under various print loads and conditions, allowing the system to adaptively identify battery type based on characteristic voltage drop patterns, thereby improving detection accuracy while maintaining high adaptability to different battery types
Solution Approach 2:
The system uses feedback from voltage drop measurements during printing to iteratively refine battery type identification. The control unit continuously monitors voltage characteristics during operation, compares them against expected patterns for primary and secondary batteries, and adjusts the identified battery type accordingly, thereby improving detection accuracy through operational feedback while maintaining versatility
