Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recording apparatuses face issues with dirtiness due to excessive recording material, particularly on recording media that swell or jam, leading to smudging and clogging.
Innovation Solution
A recording apparatus with a controller that adjusts the amount of recording material based on an adjustment value and an index value for dirtiness, reducing the material usage to prevent smudging and clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the amount of recording material is increased to improve image density and quality, then image quality is improved, but dirtiness and smudging occur on the recording medium and recording part
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the recording material amount based on the absorption characteristics of different recording media. The controller modifies recording parameters (such as ink ejection amount or toner application amount) according to the absorption level detected for each medium type, thereby optimizing image quality while preventing dirtiness and smudging caused by excessive material application.
Solution Approach 2:
The patent implements feedback control by detecting the absorption characteristics of the recording medium and using this information to adjust the recording material amount. The system measures or estimates the absorption level, compares it with target values, and automatically adjusts recording parameters to maintain optimal image quality while preventing harmful effects of excessive material application.
2Reliability
If the amount of recording material is increased to ensure complete coverage, then coverage is improved, but jamming and clogging of the recording medium occurs
Solution Approach 1:
The patent changes recording parameters dynamically based on the detected absorption characteristics of the recording medium. By adjusting the amount of recording material applied according to the medium's absorption capacity, the system ensures complete coverage without applying excessive material that would cause jamming or clogging.
Solution Approach 2:
The patent applies partial action by adjusting the recording material amount to match the actual absorption needs of the medium. Instead of applying a fixed excessive amount, the system applies only the necessary amount based on detected absorption characteristics, thereby ensuring coverage completeness while avoiding the harmful effects of excessive material application.
3Object-affected harmful factors
If the recording material amount is adjusted dynamically, then dirtiness is suppressed, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent uses feedback control to suppress dirtiness by detecting absorption characteristics and automatically adjusting recording material amount. The controller receives absorption information, processes it, and adjusts recording parameters accordingly, creating a closed-loop system that suppresses dirtiness without requiring complex manual intervention or multiple separate control mechanisms.
Solution Approach 2:
The patent implements self-service control where the system automatically detects absorption characteristics and adjusts recording parameters without external intervention. The controller autonomously manages the recording material amount based on detected medium properties, reducing the need for additional complex control mechanisms while effectively suppressing dirtiness.

AI summary
There is provided a recording apparatus including: a recording part configured to perform a recording of an image onto a recording medium with a recording material; and a controller configured to adjust, based on an adjustment value, an amount of the recording material which is to be used at a time of the recording. The controller is configured to execute, based on an index value regarding dirtiness, a changing processing of changing at least one of the adjustment value and a value regarding the adjustment value, in a direction of decreasing the amount of the recording material.
