Wiper Pin and Hole Attachment for Transport Belt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices, such as those described in JP-A-2012-116619, face issues with the secondary blade falling due to its own weight during replacement, leading to decreased workability and efficiency in the process.
Innovation Solution
A transport device with a wiper mechanism that includes a base portion and an attachment portion with pins and holes, allowing the wiper to be securely attached and preventing it from falling, even when the holding portion is released, using a combination of pins and holes to maintain the wiper's position and a protrusion and recession design to reduce adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holding portion is released to allow wiper replacement, then the wiper can be detached from the attachment portion, but the wiper falls under its own weight causing deterioration of workability
Solution Approach 1:
The pin is preliminarily inserted into the hole at a position that protrudes from the attachment portion surface. This preliminary positioning ensures that when the holding portion is released, the pin remains engaged with the hole, preventing the wiper from falling under its own weight while still allowing intentional detachment when needed.
Solution Approach 2:
The pin acts as an intermediary element between the wiper base portion and the attachment portion. It provides a mechanical connection that maintains the wiper in position during normal operation but allows controlled detachment when the holding portion is released, solving the contradiction between stability and replaceability.
2Reliability
If the wiper is securely attached during operation, then the wiper remains in position, but the replacement process becomes more complex
Solution Approach 1:
The attachment mechanism is segmented into two simple components: a pin element on the wiper base portion and a corresponding hole in the attachment portion. This segmentation creates a straightforward insertion-based connection that provides secure attachment during operation while maintaining simplicity for easy replacement without complex locking or fastening mechanisms.

AI summary
Provided are a transporting belt including a support face configured to support a medium, the transporting belt being configured to transport the medium; a wiper configured to wipe the support face; an attachment portion to which the wiper is attached; and a holding portion configured to switch between a pressing state in which the wiper is pressed against the attachment portion and a release state in which the pressure of the wiper against the attachment portion is released, in which the wiper includes a base portion attached to the attachment portion, either one of the base portion and the attachment portion includes at least one pin, and the other one includes a hole through which the at least one pine is inserted.
