Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses do not accurately account for the power supply status during charging, leading to discrepancies between calculated and actual printing time.
Innovation Solution
The printing apparatus acquires and utilizes power supply information to calculate and display accurate printing time, taking into account the charging status and power consumption for each operation type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the printing apparatus calculates printing time based on stored power capacity alone, then the calculation is simple, but the printing time estimate becomes inaccurate due to not considering power supply status during charging
Solution Approach 1:
The control unit acquires power supply information in advance before calculating printing time. By obtaining data about the power supply status (including charging speed and expected charging completion time) beforehand, the system can make more accurate printing time estimates that account for both current stored power and upcoming power replenishment, rather than simply reacting when power runs low.
Solution Approach 2:
The system continuously monitors and acquires power supply information feedback, including the status of the power storage portion during charging. This feedback loop allows the control unit to adjust printing time calculations dynamically based on actual charging performance and power supply conditions, improving accuracy over static calculations.
2Reliability
If the printing apparatus stops printing operation to charge the power storage portion when stored power falls below a threshold, then the power storage is maintained, but printing productivity is reduced due to interruptions
Solution Approach 1:
By acquiring power supply information in advance, the system can predict when charging will complete and plan printing operations accordingly. This allows the system to maintain printing operations longer by anticipating power availability, rather than conservatively stopping at fixed power thresholds.
Solution Approach 2:
The printing operation control becomes dynamic rather than static. Instead of using a fixed power threshold to trigger charging interruptions, the system adaptively adjusts printing operations based on real-time power supply status and predicted charging completion, optimizing the balance between power reliability and printing productivity.
3Ease of operation
If the printing apparatus uses a fixed power threshold to trigger charging, then the control logic is simple, but the printing time calculation does not reflect actual power supply conditions
Solution Approach 1:
The control unit acquires comprehensive power supply information before making control decisions. This preliminary acquisition of data about charging status, power supply capacity, and expected charging time enables the system to make informed decisions without complex real-time calculations during printing operations.
Solution Approach 2:
The system incorporates feedback from power supply status monitoring into the control logic. By continuously acquiring information about the power storage portion's charging state and power supply conditions, the system maintains simple control structures while avoiding information loss about actual power availability.

AI summary
A technique capable of acquiring printing time according to the status of power supply to a power storage portion is provided. A printing apparatus that comprises a power storage unit (302) capable of storing power supplied via a USB cable and can operate using the power supplied from the power storage unit, the printing apparatus (10) includes: a printing unit (206) configured to perform printing on a printing medium; and a notification unit (216) configured to provide notification of charging time in which the power storage unit is charged with power supplied from the USB cable and time based on printing time in which the printing medium is printed by the printing unit.
