Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sheet processing devices often suffer from deteriorated processing quality due to creases or deflections in sheets, which affect the quality of post-processing operations such as stapling and folding.
Innovation Solution
A sheet processing device with a flexible member and a pressing mechanism that uses a first and second member to adjust the position of deflections in the sheet, eliminating creases through controlled deflection of a flexible member, thereby ensuring proper alignment and stapling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional sheet processing device processes sheets without deflection control, then the device complexity is low, but the processing quality deteriorates due to creases and misalignment
Solution Approach 1:
The flexible member automatically adjusts to the sheet's deflection state through its own elasticity, pressing the sheet flat without requiring external sensors or control systems. The system uses the sheet's own properties (flexibility, thickness) to drive the deflection correction, eliminating the need for complex detection and control mechanisms.
Solution Approach 2:
The flexible member changes its physical state from a relaxed configuration to a pressed configuration by utilizing elastic deformation. When the sheet is placed on the tray, the flexible member elastically deforms to conform to the sheet's surface, automatically adjusting its shape parameter to match the sheet's deflection state and thereby flattening the sheet.
2Manufacturing precision
If sensors are added to detect sheet deflection, then processing quality improves, but the device complexity and cost increase
Solution Approach 1:
The flexible member acts as a passive, self-adjusting element that automatically responds to sheet deflection without requiring active sensing or control. The elastic deformation of the flexible member itself serves as the deflection detection and correction mechanism, replacing the need for separate sensors and control systems.
Solution Approach 2:
The flexible member is a simple, inexpensive mechanical element that can be easily replaced if needed. It uses basic elastic materials rather than expensive electronic sensors, providing a cost-effective solution that sacrifices complexity for reliability and ease of manufacture.
3Stability of the object's composition
If the flexible member is made rigid to ensure stability, then positional stability improves, but the ability to adapt to sheet deflection is lost
Solution Approach 1:
The flexible member transitions from a static, rigid structure to a dynamic, adaptable structure that can change its shape in response to the sheet's deflection. The flexibility allows the member to dynamically adjust its position and shape during the sheet processing operation, maintaining contact with the sheet surface while providing pressing force.
Solution Approach 2:
The flexible member is designed as a thin, flexible structure that can conform to the sheet's surface while maintaining its pressing function. This flexible shell structure provides both adaptability to various sheet deflection states and sufficient structural integrity to exert the necessary pressing force.

AI summary
A sheet processing device in an embodiment includes a processing section, a tray, a lifting and lowering device, a flexible member, a first member, and a second member. The processing section processes a sheet. The sheet can be placed on a first surface on a first side of the tray. The lifting and lowering device moves the sheet to the processing section. The flexible member is provided on the first side of the tray and has flexibility. The first member is connected to a first end portion of the flexible member. The second member is connected to a second end portion opposite to the first end portion of the flexible member. The second member is separated from the first member in a first direction. A separation distance between the second member and the first member is shorter than length of the flexible member between the second member and the first member.
