Adjustable Stamp Flip-Up Cover Mechanism

Solution Overview

Problem

Existing adjustable stamps stain users' fingers with ink when disassembling and assembling the printing type cover, as the process requires direct contact with the inked surface.

Innovation Solution

A flip-up printing type cover unit with a torsion spring and fastener mechanism that allows the cover to be opened and closed without direct contact with the inked surface, preventing finger staining during adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the printing type cover is directly disassembled and assembled for adjusting printing types, then the adjustment operation is simple, but users' fingers are stained with ink

Engineering Contradiction:

Improveadjustment operation simplicityVSAvoidfinger staining

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A transparent protective film is applied to the printing type cover, serving as an intermediary barrier between the user's fingers and the inked printing types. This film allows users to adjust printing types by touching the film surface rather than directly contacting the ink, thereby preventing finger staining while maintaining operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

A thin transparent film is used to cover the printing type cover surface. This flexible film conforms to the shape of the printing types and provides a protective barrier that prevents ink transfer to fingers during adjustment operations, while still allowing tactile feedback and visual inspection.

Inventive Principle:

Principle #30Flexible shells and thin films

2Object-affected harmful factors

If a flip-up printing type cover is used to prevent finger staining, then finger staining is reduced, but the device complexity increases

AI summary

An adjustment wheel assembly of an adjustable stamp, mounted on an adjustment wheel unit of the adjustable stamp, has a printing type cover combined with a torsion spring and pivotally mounted on the adjustable wheel unit, and a fastener mounted on the adjustment wheel unit. The printing type cover has a tab and a snap part formed on another side of the printing type cover to engage the fastener and disengage the fastener when a pressing part of the fastener is pressed. The torsion spring enables the printing type cover to flip up. The printing type cover is closed and fixed by pressing down the tab formed on an edge portion of the printing type cover. Accordingly, users' fingers can be prevented from being stained upon flipping up and closing the printing type cover.
