Loading Tray Roller Installation via Flexible Holding Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium conveying apparatuses face challenges in satisfactorily installing a roller to assist medium conveyance within the loading tray, leading to potential jamming and inefficiencies in medium handling.
Innovation Solution
The medium conveying apparatus incorporates a loading tray with a placement surface featuring an opening and a holding part comprising first and second arms that can be bent outward to facilitate the installation and securement of an auxiliary roller, which assists in medium conveyance by reducing friction and preventing erroneous removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roller to assist conveyance is installed in the loading tray, then medium conveyance reliability is improved, but device complexity increases
Solution Approach 1:
The holding part is integrated into the loading tray structure, with the first and second arms forming a nested configuration that accommodates the roller while maintaining a compact overall structure. The arms can be inserted into recesses of the loading tray, creating a nested arrangement that reduces structural complexity.
Solution Approach 2:
The holding part is designed with movable arms that can flexibly adjust their position. The first and second arms are connected in a manner that allows them to move dynamically during roller installation and medium conveyance, enabling easy roller replacement while maintaining reliability.
2Strength
If the holding part uses rigid arms, then structural strength is improved, but ease of operation deteriorates
Solution Approach 1:
The holding part employs flexible arms that can bend and deform during roller installation. The arms are designed with appropriate flexibility to allow easy insertion and removal of the roller while maintaining sufficient structural strength to hold the roller securely during operation.
Solution Approach 2:
The arms are designed to be dynamically flexible during installation but statically strong during operation. The flexible connection between the first and second arms allows them to adapt to installation forces while maintaining structural integrity when supporting the roller.
3Adaptability or versatility
If the arms are made long to accommodate the roller, then adaptability is improved, but device complexity increases
Solution Approach 1:
The holding part is segmented into a first arm and a second arm connected by a flexible joint. This segmentation allows each arm to be shorter and simpler while collectively providing the necessary adaptability to accommodate the roller through their coordinated movement and flexible connection.

AI summary
Provided is a medium conveying apparatus to be able to satisfactorily install a roller to assist conveyance of a medium to a loading tray. A medium conveying apparatus includes a loading tray including a placement surface provided with an opening, to place a medium, a roller to assist conveyance of the medium, and a holding part provided on the placement surface, to hold both ends of a rotation axis of the roller. The holding part includes a first arm and a second arm standing on a front side of the placement surface. At least one of the first arm and the second arm is provided to be bent outward in a direction perpendicular to a medium conveying direction when the roller is installed from a back side of the placement surface through the opening.
