Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face inefficiencies in determining the position or density of marks due to varying use conditions, leading to potential deterioration in mark determination precision and increased toner consumption.
Innovation Solution
An image forming apparatus is configured with a detection section to determine the position or density of marks, a correction section to adjust image formation based on these determinations, and a control section that adjusts mark patterns by altering elements such as width, density, and number of marks based on predictive assessments of determination precision, ensuring optimal mark determination efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same mark is always used for determination, then the determination process is simple, but the efficiency in time and toner consumption deteriorates under varying use conditions
Solution Approach 1:
The patent applies dynamics by making the mark pattern adjustable rather than fixed. The control section dynamically changes mark elements (width, density, number of marks) based on determination precision requirements and use conditions, allowing the system to adapt between simple and complex mark configurations as needed.
Solution Approach 2:
The patent implements parameter changes by modifying mark characteristics such as width, density, and number of marks based on determination precision requirements. The control section adjusts these parameters according to use conditions to optimize both determination efficiency and toner consumption.
2Measurement precision
If mark elements are increased to improve determination precision, then determination precision improves, but toner consumption increases
Solution Approach 1:
The patent uses parameter changes to adjust mark elements (width, density, number of marks) based on actual determination precision requirements. The control section increases or decreases these parameters dynamically, ensuring high precision only when necessary and reducing toner consumption when high precision is not required.
Solution Approach 2:
The patent applies partial action by using the minimum necessary mark elements to achieve adequate determination precision. Rather than always using maximum mark complexity, the system uses only the required level of complexity for each determination task, reducing unnecessary toner consumption.
3Ease of operation
If a fixed mark pattern is used, then the device operation is simple, but adaptability to varying use conditions deteriorates
Solution Approach 1:
The patent implements dynamics by enabling the mark pattern to change automatically based on use conditions and determination precision requirements. The control section manages these changes transparently, maintaining ease of operation while significantly improving adaptability to varying conditions.
Solution Approach 2:
The patent applies universality by designing a mark formation system that can perform multiple functions: using simple marks when conditions permit and complex marks when precision is required. This multi-functional capability allows the same system to adapt to various use conditions without requiring separate dedicated systems.

AI summary
An image forming apparatus includes a first determination section which determines at least one of a position and a density of a mark; a correction section which corrects at least one of an image forming position and an image formation density of a formation section; a second determination section which determines whether a related element which affects the determination result by the first determination section satisfies a set condition; and a control section which controls the formation section to form a mark based on a mark element including at least one of: a width in the moving direction of the object; a width in a direction perpendicular to the moving direction; a density; a distance with an adjacent mark in a pattern; and a number of marks in the pattern, which is increased when the second determination section determine that the related element satisfies the set condition.
