Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoloring apparatuses for Multi-Function Peripherals (MFPs) face inefficiencies in power consumption and warm-up time due to uniform temperature and conveyance speed settings across varying paper coverage rates, leading to wasted energy and prolonged decoloring processes.
Innovation Solution
A decoloring apparatus with a controller that adjusts the set temperature and conveyance speed based on specific coverage rates, optimizing heat application and reducing power consumption by prioritizing lower temperatures for higher coverage rates and higher speeds when a next job is pending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform temperature settings are used for all coverage rates, then decoloring completeness is ensured, but power consumption increases and warm-up time is prolonged
Solution Approach 1:
The patent applies local quality by setting different temperature parameters for different coverage rates. The storage section stores multiple sets of temperature and conveyance speed settings corresponding to different coverage rates (first through fourth coverage rates). The controller selects appropriate settings based on the actual coverage rate, applying locally optimized temperature rather than uniform temperature across all cases, thereby reducing power consumption while ensuring adequate decoloring for each specific coverage rate.
Solution Approach 2:
The patent implements parameter changes by varying both temperature and conveyance speed parameters according to coverage rate. The storage section contains multiple parameter sets with different temperature values and conveyance speed values. The controller dynamically selects and switches between these parameter sets based on detected coverage rate, optimizing the balance between decoloring effectiveness and power consumption for each specific coverage rate scenario.
2Reliability
If higher temperature is used for higher coverage rates, then decoloring effectiveness improves, but warm-up time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple optimized temperature and conveyance speed settings in the storage section before operation begins. These settings are prepared in advance for different coverage rate scenarios. When a specific coverage rate is detected, the controller immediately retrieves and applies the pre-prepared corresponding settings, avoiding the need to calculate or adjust parameters in real-time, thus reducing warm-up time while ensuring decoloring effectiveness.
Solution Approach 2:
The patent implements dynamics by making the temperature and conveyance speed settings changeable and adaptable based on coverage rate. Rather than using fixed uniform settings, the system dynamically selects from multiple stored settings according to the actual coverage rate. This dynamic adaptation allows the system to use lower temperatures for lower coverage rates (reducing warm-up time) while maintaining adequate decoloring effectiveness through higher temperatures for higher coverage rates when necessary.
3Use of energy by moving object
If conveyance speed is reduced for higher coverage rates, then heat application efficiency improves, but processing speed decreases
Solution Approach 1:
The patent applies parameter changes by simultaneously optimizing both temperature and conveyance speed parameters based on coverage rate. For lower coverage rates, the system uses higher conveyance speeds with appropriately adjusted temperatures, maintaining heat application efficiency while improving processing speed. For higher coverage rates, lower conveyance speeds with higher temperatures ensure adequate heat application. This coordinated parameter optimization resolves the contradiction between heat application efficiency and processing speed.
Solution Approach 2:
The patent implements dynamics by making conveyance speed variable and adaptive to coverage rate conditions. The controller dynamically adjusts conveyance speed based on the detected coverage rate, rather than maintaining a fixed speed. This dynamic adjustment allows the system to optimize the balance between heat application efficiency and processing speed for each specific coverage rate scenario, improving overall productivity without sacrificing decoloring quality.

AI summary
A decoloring apparatus includes a decoloring assembly, a driver configured to drive the decoloring section, and a storage configured to store first setting information, as setting information when there is no next job, and second setting information, as setting information when there is a next job, and a controller. The controller is configured to perform control to drive the decoloring assembly based on conveyance speed and set temperature corresponding to a predetermined coverage rate of the image receiving medium in the first setting information stored in the storage if there is no next job, or perform control to drive the decoloring assembly based on the conveyance speed and the set temperature corresponding to a predetermined coverage rate of the image receiving medium in the second setting information stored in the storage if there is a next job.
