Stamp MB Unit Height Adjustment via Angled Link Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stamps with central spars face issues with space constraints, leading to offset pattern alignment and require independent adjustment of screws for the MB unit, resulting in potential misalignment and varied imprint images.
Innovation Solution
A stamp design with a central height adjustment element accessible from the front or rear, utilizing a single adjustment screw and an angled link track for parallel displacement of the MB unit, allowing for easy setup and alignment with the text plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a central spar is used to accommodate spring elements, then the structural stability is improved, but the space for viewing window arrangement is eliminated and pattern alignment becomes offset
Solution Approach 1:
The patent divides the spring element accommodation from the central spar structure. Instead of placing spring elements in the central spar, the invention uses separate spring elements arranged on the side parts of the bracket-shaped upper part, allowing the central area to remain clear for viewing window arrangement and proper pattern alignment.
2Adaptability or versatility
If two independent adjustment elements are used for MB unit height adjustment, then the adjustment range is increased, but the alignment precision deteriorates due to independent adjustment requirements
Solution Approach 1:
The patent combines two independent adjustment elements into a single integrated adjustment mechanism. The single adjustment element simultaneously controls both sides of the MB unit height, ensuring parallel adjustment and maintaining alignment precision while providing sufficient adjustment range.
3Device complexity
If adjustment elements are arranged on the top side, then the adjustment mechanism is simplified, but the accessibility is reduced requiring additional positions for setup
Solution Approach 1:
The patent relocates the adjustment element from the top side to the front or rear side of the stamp. This spatial repositioning in a different dimension allows the adjustment element to be accessible during normal rest and stamping positions without requiring additional setup positions, while maintaining a simple adjustment mechanism.
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
Enables precise and easy height adjustment of the MB unit relative to the text plate, ensuring accurate imprint alignment without additional positions, enhancing usability and impression quality.
Implementation Method 1
spring elements for returning the upper part to the rest position
Implementation Method 2
The impression unit can be adjusted via a turning mechanism from a rest position, in which the ink is picked up by a pad arranged in an ink pad, into an impression position against a spring force

AI summary
The invention describes a stamp (1) comprising at least one stamp component (2) and an impression unit (3) with an MB unit (assembled ribbon set unit) (19), wherein the stamp component (2) is formed from an upper part (4) and a lower part (6) with a pad receiving element (7), wherein the impression unit (3) with the MB unit (19) is movably connected to the upper part (4) via a reversing mechanism (11) in the lower part (6), wherein in the rest position (13) a text plate (15) mounted on the impression unit (3) and a stamp area of the MB unit (19) rests against a stamp pad (16) impregnated with stamp ink in the pad receiving element (7).During a stamping process to produce a stamp impression, the impression unit (3), in particular with a mounted text plate (15), and the MB unit (19) are adjustable to a stamping position (14) via the reversing mechanism (11), wherein at least one adjusting element (34, 44) is arranged on the MB unit (19). The adjusting element (34, 44) is accessible or operable in a rest position (13) or a stamping position (14) via the front (42) or back (43), wherein the adjusting element (34, 44) is designed for adjusting the height of the MB unit (19).
