Solution Overview

Problem

The existing dovetail mounting system for numbering devices on numbering cylinders is prone to loosening and detachment, causing damage, and is difficult to adjust and adapt to different cylinder diameters.

Innovation Solution

A T-shaped or V-shaped mounting system with spring-loaded clamping elements that securely attach to annular grooves on the peripheral mounting ring, allowing for easy adjustment and secure attachment to various cylinder diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a dovetail mounting system with clamping mechanism is used to secure numbering devices, then the numbering devices can be firmly attached to the numbering cylinder, but the mounting system is prone to loosening and detachment during operation

Engineering Contradiction:
Improveattachment strengthVSAvoidmounting reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The mounting system is divided into separate functional components: the peripheral mounting ring with T-shaped cross-section, the numbering device with mounting groove, and the clamping mechanism. This segmentation allows each component to be optimized independently and facilitates easier replacement and maintenance of individual parts without affecting the entire mounting system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The T-shaped cross-section of the peripheral mounting ring introduces asymmetric geometry that prevents rotational misalignment and ensures proper orientation of the numbering device. The vertical web of the T-section engages with the mounting groove in a specific orientation, eliminating the possibility of incorrect installation and enhancing mounting reliability.

Inventive Principle:
Principle #4Asymmetry

2Adaptability or versatility

If a clamping mechanism with screws is used to secure the numbering device, then the attachment can be adjusted, but the adjustment process is difficult and time-consuming

Engineering Contradiction:
ImproveadjustabilityVSAvoidmounting ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The clamping mechanism incorporates a movable clamping part that can be easily displaced laterally to adjust the gap of the mounting groove. This dynamic adjustment capability allows for quick adaptation to different numbering device sizes and positions without requiring complex screw tightening procedures, significantly improving ease of operation while maintaining adaptability.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If the peripheral mounting ring has a fixed curvature matching a specific cylinder diameter, then the numbering device fits precisely, but it cannot be adapted to numbering cylinders with different diameters

Engineering Contradiction:
Improvemounting precisionVSAvoidcylinder diameter adaptability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The mounting system is designed with universal compatibility features that allow the same peripheral mounting ring and numbering device combination to be used across numbering cylinders of different diameters. The T-shaped cross-section and adjustable clamping mechanism work together to accommodate various curvatures, enabling one mounting system to serve multiple cylinder sizes without requiring custom-designed components for each diameter.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Strength

If the mounting groove gap is reduced to secure the numbering device, then the attachment becomes more firm, but the mounting and dismounting process becomes more difficult

Engineering Contradiction:
Improveattachment strengthVSAvoiddismounting ease
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The clamping mechanism is designed to be dynamically adjustable, allowing the gap of the mounting groove to be easily modified. During installation, the gap can be temporarily increased to facilitate mounting, then reduced to secure the numbering device firmly. For maintenance, the gap can be quickly enlarged again to enable easy dismounting. This dynamic control of the gap size resolves the contradiction between firm attachment and ease of repair.

Inventive Principle:
Principle #15Dynamics

AI summary

There is described a numbering system (1.06) for carrying out numbering in a printing press comprising a numbering cylinder, a rotatable shaft defining a rotation axis, at least one supporting disc (1.42) mounted on the rotatable shaft for rotation therewith, the supporting disc comprising a peripheral mounting ring (1.43) for mounting of at least one numbering device (1.06; 2.06) on a periphery of the supporting disc, which numbering device (1.06; 2.06) is secured to the peripheral mounting ring (1.43) by means of a clamping mechanism. The peripheral mounting ring (1.43) has a T-shaped cross-section defining a pair of annular mounting grooves (1.43a, 1.43b) on each side of the peripheral mounting ring (1.43). The numbering device (1.06; 2.06) comprises clamping elements (1.50; 2.50) on each side of the numbering device (1.06; 2.06) which are adapted to cooperate with the annular mounting grooves (1.43a,. 1.43b) for securing the numbering device (1.06; 2.06) onto the peripheral mounting ring (1.43). The clamping elements (1.50; 2.50) are preferably spring-loaded clamping elements.
