Solution Overview

Problem

Existing labeling machines lack flexibility in adapting to different work processes without compromising operational safety, as the protective mechanisms often impair functionality or create gaps that allow user intervention.

Innovation Solution

A labeling machine design featuring a combination of stationary and displaceable protective elements that can be adjusted to various positions, ensuring protection of the label transfer area from user intervention without protruding into the carousel's working area, thus allowing flexible operation while maintaining safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a one-piece movable guard is used to protect the label transfer area, then operational safety is improved, but the flexibility to adjust the functional part position is reduced

Engineering Contradiction:
Improveoperational safetyVSAvoidflexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The unit guard is divided into a fixed base and a movable protective element that can be independently positioned. This segmentation allows the protective function to be maintained while enabling flexible adjustment of the functional part relative to the carousel, resolving the contradiction between safety and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protective element is designed to be movable relative to the base, transforming the static guard into a dynamic system. This allows the guard to adapt its position according to different operating requirements while maintaining continuous protection of the label transfer area.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the guard projects far into the working area to prevent gaps, then operational safety is improved, but the functionality of the carousel is impaired

Engineering Contradiction:
Improveoperational safetyVSAvoidfunctionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective element can move between different positions, allowing it to project into the working area only when needed for safety, while retracting when container transport requires clear access. This dynamic positioning resolves the contradiction between safety coverage and operational functionality.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the functional part is moved close to the carousel for different container formats, then adaptability is improved, but gaps may be created that compromise safety

Engineering Contradiction:
Improveadaptability to container formatsVSAvoidoperational safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The movable protective element can be positioned to follow the functional part's movement relative to the carousel, maintaining continuous coverage and preventing gap formation even when the functional part is adjusted for different container formats.

Inventive Principle:
Principle #15Dynamics
