Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet storing devices face issues with capacity limitations and scattering of folded sheets due to irregular storage conditions, particularly when sheets with varying widths are stacked, leading to misalignment and incorrect superposition.
Innovation Solution
A sheet storing device with a conveyance system that adjusts the distance from the holding position to the storage section, allowing sheets to be dropped and stored vertically, using a combination of belt units and a pressing mechanism to ensure alignment and orderly stacking, regardless of sheet size or type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If folded sheets are stored in a box-shaped storing device under irregular conditions, then the storing device can accommodate sheets of various sizes, but the capacity of the storing device runs short and the ejected sheets scatter
Solution Approach 1:
The patent applies the dynamics principle by making the holding lower end position adjustable rather than fixed. The conveyance device can change its holding position vertically to match different sheet widths, allowing the storing device to adapt to various sheet sizes while maintaining proper alignment and preventing scattering. This dynamic adjustment resolves the contradiction between versatility and capacity utilization.
Solution Approach 2:
The patent changes the parameter of the holding position height to accommodate different sheet widths. By adjusting the vertical position of the holding lower end, the system can properly store sheets of varying dimensions, maximizing storage capacity while maintaining order and preventing sheet scattering.
2Adaptability or versatility
If folded sheets with varying widths are stacked one after another, then the storing device can handle different sheet types, but sheets are not superposed under the correct order and they are not aligned
Solution Approach 1:
The conveyance device dynamically adjusts its holding lower end position to match the width of each sheet being stored. This dynamic positioning ensures that sheets of varying widths are properly aligned and superposed in the correct order, resolving the contradiction between handling different sheet types and maintaining alignment precision.
Solution Approach 2:
The system uses detection means to sense the width of incoming sheets and adjusts the holding lower end position accordingly. This feedback mechanism ensures proper alignment and superposition order for sheets of different widths, eliminating misalignment while maintaining versatility.
3Device complexity
If a fixed holding position is used for the conveyance device, then the device structure is simple, but sheets of different widths cannot be stored properly
Solution Approach 1:
The patent transforms the fixed holding position into a dynamic, adjustable position that can move vertically to accommodate different sheet widths. This dynamic feature, while adding some structural complexity, enables the device to handle various sheet types properly, resolving the contradiction between simplicity and adaptability.
