Solution Overview

Problem

Deli slicers lack integrated packaging capabilities to prevent food slices from rejoining once stacked and packaged, which affects the efficiency and quality of food handling and storage.

Innovation Solution

An add-on device for slicing machines that includes a container with a sheet tray, alternating types of separation sheets, a mechanic/electro-mechanic mechanism for loading sheets, a three-position lever, and an electronic system to monitor and control the interleaving process, ensuring sheets are inserted between food slices to prevent rejoining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separation sheets are added to prevent food slices from rejoining, then packaging quality is improved, but device complexity increases

Engineering Contradiction:
Improvepackaging qualityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces separation sheets as intermediary elements between food slices to prevent them from rejoining. These sheets act as mediators that physically separate the slices during stacking and packaging, solving the reliability issue without requiring complex mechanical intervention in the slicing mechanism itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The separation sheet insertion function is extracted as a distinct add-on device that operates independently from the main slicing mechanism. This allows the core slicing function to remain simple while the packaging enhancement is implemented as a separate, modular component that can be added or removed as needed.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If an add-on device with multiple components is integrated, then slicing and packaging capabilities are combined, but ease of operation deteriorates

Engineering Contradiction:
Improvepackaging capabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The add-on device is designed to automatically perform the separation sheet insertion process. The mechanism self-regulates the timing and placement of sheets as food slices pass through, eliminating the need for manual intervention and maintaining ease of operation despite the added functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The separation sheet insertion mechanism is merged with the existing food slice conveyance path. By integrating the sheet insertion process into the natural flow of slice movement, the system combines slicing and packaging functions without requiring separate operational steps or increasing user burden.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If a mechanical/electro-mechanical mechanism is added for sheet insertion, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvepackaging efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mechanical/electro-mechanical mechanism operates continuously as food slices are being sliced and conveyed. The separation sheet insertion occurs in continuous synchronization with the slicing process, ensuring that every slice receives appropriate separation without interrupting the production flow, thereby improving packaging efficiency.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent employs electro-mechanical actuators to replace purely manual or complex mechanical systems for sheet insertion. By using electrically controlled mechanisms, the system achieves precise, automated sheet placement with simpler control logic and reduced mechanical complexity compared to traditional purely mechanical approaches.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
