Innovation Solution
An image forming apparatus that includes an acquiring unit for rendering information, a first image forming unit for forming images on a sheet, and a second image forming unit for creating an electrostatic attraction toner image, which allows the sheet to be attracted to an object surface using static electricity, with user-selectable modes for enhancing and imparting electrostatic attraction functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional image forming technology is used, then images can be formed on sheets, but the sheets cannot be attracted to surfaces using static electricity
Solution Approach 1:
The patent applies parameter changes by modifying the physical-chemical properties of the sheet surface through toner application. The toner contains electrostatic charge and forms a layer on the sheet that enables electrostatic attraction to surfaces, fundamentally changing the electrical parameters of the sheet material.
Solution Approach 2:
The invention uses composite materials by combining the sheet material with toner particles that possess electrostatic properties. The toner acts as a functional coating layer that imparts electrostatic attraction capability to the otherwise non-conductive sheet, creating a composite structure with enhanced functionality.
2Productivity
If sheets are used once and discarded, then simplicity is maintained, but resource waste occurs and reuse functionality is lost
Solution Approach 1:
The patent implements discarding and recovering by enabling the sheet to be reused through electrostatic attraction. Instead of discarding sheets after single use, the electrostatically charged toner layer allows sheets to be adhered to surfaces for repeated use, and the charge can be refreshed or maintained over multiple cycles.
Solution Approach 2:
The sheet with electrostatic toner coating serves itself by maintaining electrostatic charge that enables automatic adhesion to surfaces without additional mechanisms. The electrostatic property inherently provides the attraction function, eliminating the need for external adhesives or complex fixing systems.
3Reliability
If electrostatic attraction function is added to sheets, then adhesion to surfaces is enabled, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the image forming process with the electrostatic function imparting process. The same toner application mechanism that creates the visible image also imparts the electrostatic attraction function, combining two functions into a single manufacturing step rather than requiring separate processes.
Solution Approach 2:
The toner serves multiple functions simultaneously: it creates the visible image pattern and imparts the electrostatic attraction property to the sheet. This multi-functionality eliminates the need for separate functional coatings or additional manufacturing steps, simplifying the overall process despite adding functionality.
