Crimping Teeth Binding and Unbinding Sheet Bundles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing devices face challenges in efficiently unbinding sheet bundles without damaging the crimped portion, as the crimped area can be difficult to remove and may be damaged when attempting to loosen the bundle.
Innovation Solution
A medium processing device equipped with crimping teeth and circuitry that presses and deforms the sheet bundle to bind it, and then flattens the crimped area to unbind it, using a movement assembly and flat plate teeth to facilitate the unbinding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate unbinding device is provided to prevent damage to the crimped portion, then the reliability of sheet removal is improved, but the device complexity increases and the apparatus size increases
Solution Approach 1:
The patent combines the binding function and unbinding function into a single integrated device. The same crimping teeth that perform binding are used to perform unbinding by applying flattening force to the crimped portion, eliminating the need for a separate unbinding device and reducing overall device complexity while maintaining reliable sheet removal
Solution Approach 2:
The crimping teeth are designed to perform multiple functions: binding sheets by crimping and unbinding sheets by flattening the crimped portion. This multi-functional design allows a single component to handle both binding and unbinding operations, reducing the number of components needed while ensuring reliable sheet removal without damage
2Strength
If the crimped portion is pressed and deformed to bind the sheet bundle, then the binding strength is improved, but the difficulty of unbinding increases and may cause damage
Solution Approach 1:
The patent applies the inverse action principle by using the same crimping teeth to perform both crimping (binding) and flattening (unbinding) operations. By reversing the action - pressing down to bind and then pressing up to flatten - the device maintains strong binding while enabling easy unbinding without damage to the crimped portion
3Ease of operation
If flat plate teeth are added to flatten the crimped area for unbinding, then the ease of unbinding is improved, but the device complexity increases
Solution Approach 1:
The patent merges the flat plate teeth with the crimping teeth into a single integrated component. The crimping teeth structure incorporates flat plate portions that can perform both crimping and flattening functions, eliminating the need for separate flat plate teeth components and reducing device complexity while maintaining easy unbinding operation
