Curved Stacker Paddle Elastic Deformation for Medium Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medium processing devices face issues with misalignment and weak pressing force due to the flat paddle portion resting on the medium, leading to potential misalignment during the stacking process.
Innovation Solution
A stacker with a medium stacking portion, a medium butting portion, and a paddle mechanism that includes a feeding portion, allowing the paddle to stop in two modes: one where it does not contact the medium and another where it deforms upon contact, providing a stronger pressing force for alignment and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a flat paddle portion rests on the medium, then the structure is simple, but the pressing force is weak causing misalignment
Solution Approach 1:
The paddle portion is changed from a flat structure to a curved structure that arches upward from the rotation axis. This curvature allows the paddle to apply pressing force more effectively to the medium while maintaining structural simplicity. The curved shape enables the paddle to contact and press the medium at multiple points along its length, increasing the overall pressing force without adding complexity.
Solution Approach 2:
The invention changes the geometric parameters of the paddle portion by introducing curvature and arching characteristics. This parameter change transforms the paddle from a rigid flat surface to a flexible curved surface that can deform under load, thereby increasing the contact area and pressing force applied to the medium for better alignment.
2Manufacturing precision
If the paddle always contacts the medium, then alignment is maintained, but the pressing force remains insufficient
Solution Approach 1:
The curved, arched shape of the paddle portion enables it to store elastic energy during rotation and release it as pressing force when contacting the medium. The curvature allows the paddle to flex and rebound, creating a stronger pressing action that effectively aligns the medium while maintaining continuous contact.
3Ease of manufacture
If the paddle structure is simplified, then ease of manufacture increases, but the ability to press and align medium decreases
Solution Approach 1:
The curved paddle design can be manufactured using standard forming processes for curved surfaces, which are well-established in industrial manufacturing. The curvature is achieved through simple bending or molding operations, maintaining ease of manufacture while significantly improving the pressing and alignment functionality compared to a flat paddle.

Function Achieved in This Case
This configuration ensures accurate alignment and secure stacking of media by applying a sufficient pressing force, reducing misalignment and enhancing the efficiency of the medium processing and stacking process.
Implementation Method 1
a paddle transporting the medium received by the medium stacking portion in a direction of the medium butting portion by rotating, and having a first mode in which the paddle stops in a state in which a feeding portion of the paddle does not contact the medium on the medium stacking portion, and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed

AI summary
A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.
