Power Control Device for Decoloring Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power control systems for decoloring devices often exceed the upper limit of power consumption, leading to potential malfunctions in power supply when installed in environments with other power-consuming devices, risking excessive current draw.
Innovation Solution
A power control device comprising a heating section, an input section, and a control section that monitors and adjusts power consumption by limiting the number of paper sheets being decolored and adjusting heating to prevent total power consumption from exceeding a predetermined value, using mechanisms like pulse width modulation and temperature detection to manage power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the decoloring device operates continuously to process paper sheets, then productivity is improved, but total power consumption exceeds the upper limit causing power supply malfunction
Solution Approach 1:
The heating section operates in periodic cycles with active heating periods and idle periods. The control section monitors total power consumption and intermittently stops the heating section when the upper limit is approached, allowing periodic operation that maintains productivity while preventing continuous overload
Solution Approach 2:
The system dynamically adjusts the heating section operation based on real-time total power consumption monitoring. The control section modifies heating duration and intensity adaptively, transitioning between full operation, reduced operation, and idle states to maintain power consumption within safe limits
2Productivity
If the heating section operates at full power to decolor paper sheets efficiently, then decoloring effectiveness is improved, but total power consumption exceeds the predetermined upper limit
Solution Approach 1:
The control section changes operational parameters of the heating section based on total power consumption levels. When total power consumption approaches the upper limit, the system adjusts heating parameters (duration, intensity) to reduce power usage while maintaining decoloring functionality
Solution Approach 2:
The heating section operates at full capacity only when necessary and safe, otherwise operating partially or intermittently. The control section determines the appropriate level of heating action based on real-time power consumption monitoring, applying full heating only when total power consumption is well below the upper limit

AI summary
A power control device includes a heating section, an input section, and a control section. The heating section is configured to heat an object. The input section is configured to receive a power consumption value. The control section is configured to control the heating section so that a total power value obtained by adding a power consumption value of the heating section and the power consumption value received by the input section does not exceed a predetermined power value.
