Solution Overview

Problem

Existing sausage-shaped product production systems pose a risk of operator injury due to the potential for fingers to enter the gap between the filling tube and the casing brake assembly during operation, despite safety measures, and there is a need for enhanced safety and hygiene in the production process.

Innovation Solution

A casing brake assembly with a safety means comprising a tubular element and a switch element, arranged coaxially with the filling tube, which interacts with the production apparatus to stop operations if an object, such as a finger, is detected, and is designed for easy cleaning and mounting, eliminating the need for additional sensor means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensor means are provided to detect the presence or absence of the casing brake assembly, then operator safety is improved by preventing machine operation without the casing brake assembly in position, but the device complexity increases and additional sensor means are required

Engineering Contradiction:
Improveoperator safetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The safety function is merged with the existing casing brake assembly structure. The tubular element and switch element are integrated into the casing brake assembly itself, combining the braking function with the safety detection function in a single integrated component rather than adding separate sensor means.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The casing brake assembly performs its own safety detection function through the switch element that detects its presence or absence. The assembly is self-sufficient in providing safety functionality without requiring external sensor systems, eliminating the need for additional sensor means.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the filling tube is shifted away for providing packaging casing or adapting the clipping machine to different products, then adaptability is improved, but the risk of operator injury increases as fingers may enter the circular opening of the casing brake assembly

Engineering Contradiction:
ImproveadaptabilityVSAvoidoperator injury risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The switch element is positioned to detect the presence or absence of the casing brake assembly before the machine operates. This preliminary detection prevents the machine from operating when the casing brake assembly is absent or improperly positioned, thereby preventing potential operator injury before it can occur.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The switch element provides feedback about the position and presence of the casing brake assembly to the control system. This feedback mechanism ensures the machine only operates when safety conditions are met, creating a closed-loop safety system that responds to the actual state of the apparatus.

Inventive Principle:
Principle #23Feedback
