Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet rollers in automatic transaction machines face challenges in achieving compactness and thinness while maintaining shape and strength, leading to limitations in space usability, design freedom, and productivity due to thickness constraints and difficulties in mounting elastic sheets of varying thicknesses.
Innovation Solution
A sheet roller design featuring a roller body coupled with a rotation shaft and U-shaped coupling members with elastic sheets interposed between them, allowing for adjustable thickness and easy assembly, with features like sheet fixing protrusions and inclined guide surfaces to stabilize the elastic sheets and facilitate assembly regardless of component order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the roller body is made thicker to maintain shape and strength, then the shape and strength are improved, but the thickness increases which limits space usability and design freedom
Solution Approach 1:
The roller body is divided into two separate components: a roller core and a roller sheet. The roller core provides the structural strength and shape, while the roller sheet is a separate elastic component that can be selectively mounted. This segmentation allows the roller body to maintain sufficient thickness for strength without being constrained by the need to accommodate coupling grooves of various depths.
Solution Approach 2:
The roller sheet is designed to be selectively mountable and removable from the roller core. The coupling members allow the roller sheet to be dynamically adjusted or replaced without changing the roller core structure. This dynamic configuration enables the system to adapt to different elastic sheet thicknesses while maintaining the roller core's structural integrity.
2Adaptability or versatility
If coupling grooves are formed deeper in the roller body to accommodate thicker elastic sheets, then thicker elastic sheets can be mounted, but the roller body thickness increases
Solution Approach 1:
The coupling function is segmented from the roller core. Instead of forming coupling grooves directly in the roller body, separate coupling members are used that interface with the roller sheet. This allows the roller core to maintain a consistent, optimized thickness while the coupling members accommodate various elastic sheet thicknesses.
Solution Approach 2:
The coupling members act as intermediary components between the roller core and the elastic sheet. These coupling members with varying depths can be selectively mounted on the roller core to accommodate different elastic sheet thicknesses, without requiring the roller core itself to be thicker or have varying groove depths.
3Manufacturing precision
If separate roller bodies and coupling pieces are fabricated for different elastic sheet thicknesses, then the correct thickness is achieved, but manufacturing complexity and time increase
Solution Approach 1:
The roller core is designed as a universal component that can accommodate multiple types of elastic sheets with different thicknesses. The standardized coupling members allow a single roller core design to work with various elastic sheet thicknesses, eliminating the need to fabricate separate roller bodies for different applications and improving manufacturing precision while maintaining productivity.
4Ease of operation
If the sheet roller is pre-assembled or post-assembled in different orders from the standard order, then assembly flexibility is improved, but components must be separated and reassembled which reduces productivity
Solution Approach 1:
The sheet roller is segmented into distinct modular components: the roller core, coupling members, and elastic sheets. This modular segmentation allows components to be assembled in different sequences without requiring complete disassembly and reassembly, as each component can be independently installed or removed from the standardized interfaces.
Solution Approach 2:
The coupling members are designed with dynamic mounting capabilities that allow the elastic sheets to be installed or removed without affecting the roller core or other components. This dynamic interface enables assembly flexibility while maintaining productivity, as components can be quickly adjusted or replaced without requiring systematic disassembly of the entire assembly.

AI summary
Disclosed is a sheet roller capable of achieving compactness and thinness, and improves space usability and design freedom. The sheet roller includes a roller body coupled with the rotation shaft, a plurality of coupling members coupled with a side surface of the roller body in order to surround a part of an outer peripheral surface of the roller body, and disposed on the outer peripheral surface of the roller body in such a manner as to be spaced apart from one another, and an elastic sheet interposed between the roller body and each of the plurality of coupling members. The roller body is formed to have a predetermined thickness thereof while maintaining a predetermined shape and strength thereof, and thus, improving space usability and the design freedom of an automatic transaction machine where the sheet roller is mounted.
