Solution Overview

Problem

Conventional self-inking stamps with a cap-like top part enclose the bottom part, limiting the size of swiveling stamping inserts and making it difficult to accommodate larger AB units, and complicating ink cartridge replacement.

Innovation Solution

A stamp design with a reversing opening on the top part and lateral grip openings that connect to a removal opening, allowing the stamping insert to swing outside and enabling 180° rotation, along with guide elements for stability and easy ink cartridge replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the top part encloses the bottom part cap-like, then the stamp structure is compact and secure, but the stamping insert cannot be swivelled and larger AB units cannot be accommodated

Engineering Contradiction:
Improveability to accommodate larger AB unitsVSAvoidstructural complexity of opening mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The stamp is divided into distinct functional sections: a closed top part for security, a reversible bottom part for stamping inserts, and a separate ink cartridge system. This segmentation allows each component to be optimized independently - the top part remains enclosed for security while the bottom part can reverse to accommodate larger AB units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bottom part is designed to be reversible (swivellable), transforming from a static enclosed structure to a dynamic one that can change orientation. This allows the stamping insert to be accessed from the rear side while maintaining a compact closed form during normal operation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the bottom part is completely closed, then the stamp structure is secure, but ink cartridge replacement becomes difficult

Engineering Contradiction:
Improveease of ink cartridge replacementVSAvoidcomplexity of opening mechanisms
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The ink cartridge is extracted as a separate, removable component from the main stamp body. The grip elements allow the ink cartridge to be easily removed and replaced without opening the main enclosed structure, maintaining security while enabling easy maintenance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Grip elements serve as intermediaries between the user and the ink cartridge. These elements extend from the top part to facilitate gripping and replacing the ink cartridge without requiring direct access to the enclosed bottom part, simplifying the replacement process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If the stamping insert is swivelled within the bottom part, then the structure remains compact, but larger AB units cannot be accommodated

Engineering Contradiction:
Improvevolume available for stamping insertVSAvoidadaptability to different AB unit sizes
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The stamping insert is accessed from a different spatial dimension - the rear side of the top part - rather than from within the bottom part's interior. This dimensional change allows larger AB units to be accommodated by approaching from the rear, bypassing the width constraints of the bottom part's interior space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The technology is relates to a stamp with a pivotable stamping insert. The stamp includes a top part with a pair of side faces; a bottom part; a receiving device for an exchangeable ink cartridge with pad having grip elements and a stamping insert with a text plate positioned in the bottom part. The stamping insert is configured to move in a vertical direction from a resting position into a stamping position for producing a stamp impression by the text plate by means of a reversing mechanism. The reversing mechanism includes a reversing opening on a rear side of the top part for the stamping insert, and on each side face of the pair of side faces there is one grip opening for reaching through to the bottom part to the grip elements of the exchangeable ink cartridge with pad.
