Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming systems face challenges in optimizing image resolution and gradation settings for different intended uses, leading to either excessive data volume or reduced accuracy in positioning and density adjustment.
Innovation Solution
An image forming apparatus with a control section that determines image characteristics based on intended use, adjusting resolution and gradation settings to optimize image quality and data efficiency, allowing for high-resolution imaging for positioning and low-resolution imaging for evidence confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution and high gradation settings are used for reading images, then positioning accuracy and density adjustment accuracy are improved, but data volume increases excessively and storage burden increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting reading resolution and gradation based on the intended use of the image. For positioning, high resolution is used; for evidence confirmation, low resolution is used. This resolves the contradiction by changing the reading parameters to match the specific application requirement, avoiding unnecessary high data volume when high precision is not needed.
Solution Approach 2:
The patent implements dynamics by making the reading characteristics variable rather than fixed. The control section determines appropriate reading resolution and gradation based on the intended use (positioning, density adjustment, or evidence confirmation). This dynamic adjustment allows the system to optimize between measurement precision and data volume depending on the specific task at hand.
2Measurement precision
If high resolution and high gradation settings are used for reading images, then density adjustment accuracy is improved, but data volume increases excessively and storage burden increases
Solution Approach 1:
The patent applies parameter changes by adjusting the gradation depth according to the intended use. For density adjustment, high gradation is used to ensure measurement precision, while for evidence confirmation, low gradation suffices. This resolves the contradiction between density adjustment accuracy and data volume by matching gradation settings to specific application needs.
Solution Approach 2:
The patent implements dynamics by making reading gradation variable based on the intended use. The control section determines appropriate gradation settings dynamically - high gradation for density adjustment tasks, low gradation for evidence confirmation. This allows optimization between measurement precision and data volume for different operational contexts.
3Device complexity
If the same reading resolution and gradation are used for all intended uses, then device complexity is reduced, but either positioning accuracy or data efficiency cannot be optimized
Solution Approach 1:
The patent implements dynamics by introducing variable reading characteristics controlled by a control section that determines appropriate settings based on intended use. While this increases control logic, it enables optimization of positioning accuracy by using high resolution when needed. The complexity increase is justified by the significant improvement in measurement precision for positioning tasks.

AI summary
In an image forming system including: an image forming section configured to form an image on a sheet; a reading section configured to read the image formed on the sheet by the image forming section; and a control section configured to control image forming by the image forming section and reading by the reading section, the control section determines characteristics on reading of the image formed on the sheet by the reading section depending on an intended use of the image to be read by the reading section.
