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

VSEngineering 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

Engineering Contradiction:
Improvestructural stabilityVSAvoidviewing window space
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveadjustment rangeVSAvoidalignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveadjustment mechanism complexityVSAvoidadjustment accessibility
Core Design Contradiction:
Device complexityVSEase of operation

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.

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