Adaptable Roller Wrinkle Reduction for Variable Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium transport apparatuses face difficulties in effectively preventing the formation of wrinkles in media of varying materials and thicknesses, as existing structures are not adaptable to different types of media.
Innovation Solution
A medium transport apparatus with a wrinkle reducing section that can change its contact surfaces to accommodate different media, including rollers with various surface characteristics, and a tension adjusting mechanism to apply appropriate tension, thereby reducing wrinkle formation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed wrinkle reducing structure is used, then the structure is simple, but it cannot effectively prevent wrinkles in media of varying materials and thicknesses
Solution Approach 1:
The roller is designed with a rotatable contact surface that can be dynamically adjusted to present different surface characteristics (smooth, textured, or patterned) to the medium being transported. This dynamic reconfiguration allows a single roller structure to adapt to various media types and thicknesses, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The roller's contact surface is divided into multiple segments or zones with different surface characteristics. Each segment can be independently selected or activated based on the specific media requirements, enabling the system to handle diverse materials effectively without requiring multiple complete rollers.
2Reliability
If multiple wrinkle reducing components are added to handle different media, then wrinkle prevention improves, but the number of components increases
Solution Approach 1:
A single roller component is designed to perform multiple functions by rotating to present different surface characteristics. This multi-functional design eliminates the need for multiple separate wrinkle reducing components, maintaining high reliability while minimizing the number of parts in the system.
Solution Approach 2:
Multiple surface characteristics that would traditionally require separate components are merged into a single roller structure. The roller integrates smooth surfaces, textured surfaces, and patterned surfaces in one component, allowing the system to achieve effective wrinkle prevention across different media types with fewer components.

AI summary
A medium transport apparatus includes a transport section (3) configured to support a medium and transport the medium (M) in a transport direction (A), and a wrinkle reducing section (46, 47) configured to come into contact with the medium to reduce the formation of wrinkles in the medium. The wrinkle reducing section can change surfaces (46a-d) to come into contact with the medium. The medium transport apparatus having such a structure enables to reduce the formation of wrinkles in the medium.
