Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies do not easily distinguish between recording material used for printing images and that used for press-bonding, making it difficult to track usage history.
Innovation Solution
An image forming apparatus with an image forming unit, sheet processing unit, and storing unit to track the history of image formation and sheet processing, including a thermal press-bonding unit for binding sheets using a recording material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single recording material is used for both image printing and sheet press-bonding, then material cost is reduced, but it becomes difficult to track and distinguish usage history between the two functions
Solution Approach 1:
The patent segments the recording material into two distinct types: one for image printing and another for sheet press-bonding. By physically separating the materials, the system can independently track consumption of each type through their respective counters, eliminating the confusion of mixed usage while maintaining comprehensive monitoring capability.
Solution Approach 2:
The patent introduces a controller as an intermediary that manages and distinguishes between different recording material usages. The controller receives information from separate counters for image printing and press-bonding, processes this data, and provides unified management, thereby enabling clear tracking of each function's material consumption without direct mixing.
2Measurement precision
If separate recording materials are used for image printing and press-bonding, then usage history tracking is improved, but device complexity and material management difficulty increase
Solution Approach 1:
The patent implements a universal controller that handles multiple functions: managing image printing operations, controlling press-bonding operations, and tracking both types of recording material usage. This single multi-functional component consolidates what would otherwise require separate management systems, reducing overall device complexity while maintaining precise tracking capabilities.
Solution Approach 2:
The patent employs feedback mechanisms where counters automatically monitor the usage of each recording material type and report to the controller. This automated feedback system eliminates the need for manual tracking, reducing operational complexity while ensuring accurate measurement and distinction of usage history for both image printing and press-bonding materials.
