Stamp Axle Bearing Element Integrated Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-inking stamps require a large number of individual parts, resulting in high assembly effort and complexity, particularly with manual installation of small components like axle bearing elements and locks.
Innovation Solution
A stamp design where the axle bearing element is pushed into the top part via guide webs and is automatically latched, with a locking head connected via an elastically deformable connecting web, allowing for simple and rapid assembly in a single working step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate parts (axle bearing element, lock, fixing disc) are used to assemble the stamp, then the reliability and functionality of the stamp are improved, but the assembly effort and device complexity increase significantly
Solution Approach 1:
The patent combines the axle bearing element and the locking head into a single integrated component. The axle bearing element includes an integrated locking head with a locking protrusion that engages with the locking recess in the top part, eliminating the need for separate locks and fixing discs. This merging reduces the number of parts from multiple components to a single piece, significantly simplifying assembly while maintaining the functional reliability of both bearing and locking mechanisms.
2Adaptability or versatility
If multiple small parts like axle bearing element and lock are used, then the stamp functionality is ensured, but manual assembly is required which reduces productivity
Solution Approach 1:
The axle bearing element is designed as a single integrated component that combines both the bearing function and the locking function. The component features a body portion that receives the axle and a locking head with a locking protrusion that engages with the top part. This integration allows the entire assembly to be installed in one operation, enabling automated assembly processes and eliminating the need for manual installation of multiple separate small parts, thereby significantly improving productivity.
3Stability of the object's composition
If the axle bearing element is securely fastened with separate locks, then the stability of the stamping position is improved, but the number of parts and assembly steps increase
Solution Approach 1:
The locking head is integrated into the axle bearing element as a single component. The locking head includes a locking protrusion that engages with a locking recess in the top part to secure the stamping position. This integration maintains the stability and reliability of the locking mechanism while reducing the number of separate parts from multiple components (axle bearing element, separate lock, fixing disc) to a single integrated piece, thereby simplifying the overall device structure.
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 solution enables quick and easy assembly of the stamp, reducing manual effort and part count, while ensuring secure fastening and operation of the locking head for precise stamping positions.
Implementation Method 1
a locking head for fixing a stamping position is connected to the axle bearing element via an elastically deformable connecting web

AI summary
The present disclosure relates to a stamp, comprising at least a stamping component and a stamping insert. The stamping component is formed of a top part and a bottom part with a cushion -receiving element and the stamping insert is connected to the top part via a reversing mechanism. The stamping insert is mounted via a continuous axle in an axle bearing element. In the resting position a text plate and/or MB unit (mounted band unit) mounted on the impression unit butts against an ink cartridge with ink pad soaked with stamping ink in the cushion-receiving element and in a stamping process for producing a stamp impression in a stamp position the stamping insert can be shifted by the reversing mechanism into a stamping position. The axle bearing element can be inserted and fastened in the top part via guide webs.
