Solution Overview

Problem

Current centrifugal slicing machines are limited in producing a variety of potato chip designs on a single production line, leading to high costs and inefficiencies in manufacturing mixed chip designs, as each design requires separate production lines and can be disrupted by maintenance issues, affecting product quality and integrity.

Innovation Solution

A stationary slicing head assembly with serially arranged knife blades of different cutting edge profiles allows for the production of multiple slice designs from a single slicing head, enabling a consistent and scalable mix of chip designs on a single production line, reducing the need for multiple production lines and minimizing product contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple production lines are used to produce different chip designs, then product variety is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveproduct varietyVSAvoidnumber of production lines
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slicing head assembly is designed to perform multiple functions by incorporating knife blades with different cutting edge profiles (flat, wavy, ridged) that can be selectively positioned. This allows a single production line to produce various chip designs, eliminating the need for multiple dedicated production lines and reducing overall system complexity.

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

Solution Approach 2:

The slicing head assembly is divided into multiple slicing shoes, each equipped with different types of knife blades. This segmentation allows independent selection and positioning of specific blade types to produce different chip designs as needed, providing flexibility without requiring entire separate production lines for each design.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If separate production lines are used for different chip designs, then product quality control is improved, but productivity and efficiency deteriorate

Engineering Contradiction:
Improveproduct quality controlVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The slicing head assembly incorporates adjustable and interchangeable knife blades that can be dynamically repositioned or replaced based on production requirements. This dynamic capability allows the system to maintain optimal cutting conditions for different chip designs while operating on a single production line, preserving quality control without sacrificing productivity.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple production lines are used to produce mixed chip designs, then product variety is improved, but loss of time and operational cost increase

Engineering Contradiction:
Improvemixed chip design productionVSAvoidmanufacturing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention merges the functionality of multiple production lines into a single integrated slicing head assembly that can produce different chip designs simultaneously or sequentially. This consolidation eliminates the time required to transfer products between separate production lines and removes the need for post-production mixing operations, significantly reducing manufacturing time and operational costs.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple production lines are used for different chip designs, then product variety is improved, but harmful factors such as product contamination increase

Engineering Contradiction:
Improvechip design varietyVSAvoidproduct contamination risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

By designing a universal slicing head assembly that can produce different chip designs within a single controlled environment, the invention eliminates the need for product transfer and mixing between separate production lines. This reduces exposure to contamination risks associated with multiple production environments and handling operations while maintaining the ability to produce diverse chip designs.

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