Solution Overview

Problem

Existing slicing machines in the food industry face challenges in cleaning and maintenance due to the disassembly of the longitudinal pressing unit, which often results in metal parts being left behind and compromising hygiene, especially when the unit is constructed from multiple parts.

Innovation Solution

A slicing machine with a longitudinal pressing unit that includes a locking unit movable between locking and release positions, allowing tool-free disassembly for easy cleaning and maintenance, reducing the risk of metal parts being lost or contacting the product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the longitudinal pressing unit is constructed from multiple parts to adapt to cross-sectional changes, then the adaptability to product dimensions is improved, but the cleaning process becomes more complex and time-consuming due to numerous gaps and spaces

Engineering Contradiction:
Improveadaptability to cross-sectional changesVSAvoidcleaning process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The longitudinal pressing unit is divided into a base body and a compensating section that can move relative to each other. The compensating section is segmented from the base body and can be disassembled independently, allowing thorough cleaning of previously difficult-to-reach areas while maintaining the adaptability to cross-sectional changes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The compensating section is designed to be movable relative to the base body in the transverse direction, allowing dynamic adaptation to varying product dimensions. This dynamic structure, combined with the ability to disassemble the compensating section, resolves the contradiction between adaptability and cleaning complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the longitudinal pressing unit is disassembled for cleaning, then thorough cleaning is achieved, but metal parts may be left behind and compromise hygiene

Engineering Contradiction:
Improvecleaning thoroughnessVSAvoidhygiene compliance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The compensating section is extracted as a separate, removable component from the base body. This extraction allows the compensating section to be completely removed and cleaned separately, eliminating the risk of metal parts being left behind in gaps and spaces, while ensuring thorough cleaning of all surfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The compensating section is designed to be easily removable and reattachable by the operator without specialized tools or procedures. This self-service design ensures that cleaning can be performed completely and consistently, reducing the risk of metal parts being overlooked.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the locking unit is designed to securely hold the compensating section, then structural stability is improved, but disassembly requires tools and increases complexity

Engineering Contradiction:
Improvestructural stabilityVSAvoiddisassembly ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The locking unit is segmented into a locking element on the base body and a corresponding locking feature on the compensating section. This segmentation allows the locking mechanism to provide secure structural stability during operation while enabling tool-free disassembly by simply moving the compensating section to release the locking engagement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking unit is designed with dynamic characteristics, allowing it to transition between a locked state (providing structural stability) and an unlocked state (enabling easy disassembly). The locking unit moves between a locking position and a release position, facilitating both stable operation and simple maintenance.

Inventive Principle:
Principle #15Dynamics
