Hand-Operated Stamp Ink Storage Retaining Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operated stamps face issues with soiling during storage member removal and insertion, complex refilling processes, and the need for complete stamp replacement when ink is depleted, due to cumbersome designs and expensive production methods.
Innovation Solution
A hand-operated stamp with a trough-shaped retaining means for the ink storage member, allowing easy manipulation without direct contact and enabling in-situ re-impregnation, combined with a latching mechanism for simple assembly and disassembly, and ink refilling channels for efficient ink distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage member is removed from the package and inserted in the stamp using conventional tools, then the storage member can be installed, but soiling occurs during handling
Solution Approach 1:
The patent introduces a retaining means as an intermediary component that holds the storage member during handling and installation. This retaining means acts as a mediator between the user's hands and the storage member, preventing direct contact and thus preventing soiling of the storage member with stamping ink.
Solution Approach 2:
The patent divides the storage member system into separate functional components: the storage member itself (containing stamping ink), the retaining means (for handling and mounting), and the stamp body. This segmentation allows the storage member to be handled indirectly through the retaining means, avoiding contamination.
2Quantity of substance
If the storage member is completely removed for refilling, then ink can be replenished, but the process becomes complex and time-consuming
Solution Approach 1:
The patent incorporates a filling socket and associated refilling mechanism that allows ink to be introduced into the storage member without complete removal. The refilling channels are pre-configured in the retaining means, enabling quick top-up operations while the storage member remains mounted in the stamp.
Solution Approach 2:
The patent extracts the refilling function from the complete removal process by providing dedicated refilling access points (filling sockets) in the retaining means. This allows the essential function of ink replenishment to be performed independently of complete storage member removal.
3Ease of operation
If the storage member is designed for easy removal and insertion, then handling is simplified, but direct contact causes soiling
Solution Approach 1:
The retaining means serves as an intermediary handling device that simplifies storage member installation while preventing direct contact. The retaining means can be easily manipulated and inserted into the stamp, carrying the storage member without requiring the user to touch the storage member directly.
4Ease of operation
If a latching mechanism is added for simple assembly, then device complexity increases, but assembly and disassembly become easier
Solution Approach 1:
The latching mechanism is designed to be self-actuating through simple user actions. The retaining means automatically engages or disengages from the stamp body through straightforward movements, making the assembly and disassembly process intuitive and easy to perform without complex mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design minimizes soiling during storage member handling, simplifies refilling, and allows for easy storage member exchange, reducing production complexity and costs while maintaining efficient ink distribution and stamp functionality.
Implementation Method 1
a partially open-pored printing plate which is displaceable against a spring force from a resting position, in which it is retracted in a housing
Implementation Method 2
said printing plate resting on an ink storage member so as to receive stamping ink therefrom

AI summary
A hand-operated stamp (1) includes an at least partially open-pored printing plate (27) which can be displaced counter to a spring force, from a resting position in which it is retracted into a housing (2), into a printing position by an actuation element (3). The printing plate rests against an ink storage body (25) in order to receive stamping ink therefrom, the ink storage body being mounted in a holder (24) which at least partially encloses it. The holder (24) is trough-shaped and is directly locked with a connecting part (6) which is locked with the actuation unit and which comprises at least one refill support (40, 41) which is oriented towards an ink refill opening (42, 43) in the base wall of the holder (24).
