Engineering Contradiction Analysis
1Productivity
If fixed charge parameters are used for all batteries, then charging process is simple and fast, but battery deterioration accelerates due to mismatched charging conditions
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting charge parameters (such as charge current, voltage thresholds, and charge termination conditions) based on the detected degradation degree of the battery. As the battery degrades, the system modifies these parameters to reduce stress on the battery, thereby extending its useful life while maintaining acceptable charging speed.
Solution Approach 2:
The patent implements dynamics by transitioning from static, fixed charge parameters to dynamic, adaptive charge parameters that change in response to battery condition. The controller continuously monitors battery degradation and adjusts charging conditions in real-time, making the charging process flexible and responsive to battery state rather than following a predetermined fixed schedule.
2Reliability
If charge parameters are customized for each battery condition, then battery useful life is extended, but charging control complexity increases
Solution Approach 1:
The patent applies feedback by implementing a closed-loop charging control system that continuously monitors battery degradation degree and uses this information to adjust charge parameters. The degradation-degree detector provides feedback to the controller, which then modifies charging conditions accordingly, creating a self-regulating system that extends battery life without requiring complex manual intervention.
Solution Approach 2:
The patent implements self-service by enabling the battery charging system to automatically adjust its own operating parameters based on its own degradation state. The system monitors its own battery condition and autonomously modifies charging conditions to optimize its performance and extend its lifespan, reducing the need for external control or complex user intervention.
3Reliability
If degradation detection and parameter correction are implemented, then battery deterioration is delayed, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies mechanics substitution by replacing complex mechanical or manual adjustment mechanisms with electronic detection and control systems. The degradation-degree detector and controller use electronic sensing and signal processing to monitor and adjust charging parameters, substituting simpler electronic systems for more complex mechanical adjustment mechanisms while achieving the same goal of extending battery life.

AI summary
A printing apparatus includes: a battery accommodating portion; a conveyor; a printing device; a power-source connector; an electric charger that charges the battery power source from an external power source when the power-source connector is connected to the external power source; and a degradation-degree detector that detects a degradation degree of the battery power source. A controller executes: a charge processing for controlling the electric charger using at least one charge parameter to charge the battery power source; storing data on the degradation degree of the battery power source based on a result of detection of the degradation-degree detector; a determining processing for determining whether a particular determination criterion relating to the degradation degree is satisfied in the stored data; and correcting the at least one charge parameter in accordance with a result of determination in the determining processing.
