Portable Stamp Ink Part Removal via Positioning Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable stamps make it difficult to replace the ink part without staining the user's hands due to the tight fit between the ink part and the stamp box, requiring manual removal that often results in contact with the ink.
Innovation Solution
The portable stamp design incorporates a positioning plate that allows the ink part to be easily removed by pressing it horizontally and then upward, avoiding direct contact with the ink layer, using a buckle system for secure attachment and a torque spring for efficient opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ink part is mounted with its edge tightly abutting the inner wall of the bottom case, then the ink part is securely fixed, but it becomes difficult to remove the ink part and causes hand staining
Solution Approach 1:
The ink part is divided into two functional segments: a base body that fits within the bottom case and a positioning plate that extends outward. This segmentation allows the base body to remain securely fixed while the positioning plate provides an external handle for easy removal without contacting the ink layer.
Solution Approach 2:
The positioning plate acts as an intermediary element between the user and the ink part. It extends out of the bottom case to provide a clean handling surface, mediating the removal process and preventing direct contact with the ink layer while still enabling secure fixation within the case.
2Stability of the object's composition
If the ink part is tightly fitted in the bottom case, then the stamp structure is stable, but the user's hands become stained during replacement
Solution Approach 1:
The ink part is segmented into a base body for stable integration within the stamp structure and a positioning plate for clean user interaction. This segmentation maintains structural stability while eliminating the harmful effect of hand staining by providing a separate handling interface.
Solution Approach 2:
The positioning plate serves as an intermediary that maintains the stable connection between the ink part and stamp structure while providing a clean handling surface that prevents ink from contacting the user's hands during replacement.
3Ease of operation
If the ink part is easily removable, then the user can replace it without staining hands, but the fixation may become less secure
Solution Approach 1:
The ink part is segmented such that the base body provides secure fixation within the bottom case while the positioning plate extends outward to enable easy removal. The segmentation allows independent optimization of both fixation security and removal ease through separate functional zones.
Solution Approach 2:
The positioning plate acts as an intermediary that enables easy removal through external handling while the base body maintains secure fixation internally. This intermediary structure decouples the functions of fixation and removal, allowing both to be optimized independently.

AI summary
A portable stamp has a stamp box, an ink part and a stamping part. The stamp box has a first case and a second case pivotally connected to the first case. The ink part and the stamping part are mounted in the first case and the second case respectively. The first case has a peripheral wall and a positioning hole formed through the peripheral wall. The ink part is mounted in the peripheral wall and has a positioning plate mounted through the positioning hole. The ink part is located in the first case by the positioning plate. When replacing a dry ink part with a new one, a user just presses the positioning plate to loosen the dry ink part from the first case. Then the user can remove the dry ink part easily and mount the new ink part in the first case.
