Solution Overview

Problem

The meat processing industry faces challenges in safely handling and transporting cutting blades due to their sharpness and risk of contamination, as well as the need for efficient storage and disposal of both new and used blades to maintain productivity and prevent premature wear or failure.

Innovation Solution

A flexible cutting blades package is created using a first and second flexible layer with an adhesive coating, where cavities are formed in the first layer to house the blades, and the second layer is sealed over with heat and pressure, forming a vacuum seal that prevents movement and potential contamination during transport and handling, allowing for safe storage and easy dispensing of blades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cutting blades are kept sharp and replaced regularly, then productivity and yield are improved, but storage and handling safety deteriorate due to accumulated sharp blades

Engineering Contradiction:
Improvemeat processing productivityVSAvoidsafety risk to workers
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The packaging system segments multiple blades into individual compartments within a single package, allowing plants to store multiple blades safely without handling loose sharp blades. The cavity structure divides the package into separate sections, each containing one blade, eliminating the need to handle multiple separate sharp objects.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible package acts as an intermediary container that safely holds and transports blades. The layered structure with adhesive bonds creates a protective barrier between workers and sharp blade edges, allowing safe handling of multiple blades simultaneously through the package rather than individually.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If blades are stored loosely for easy access, then ease of operation is improved, but contamination risk worsens

Engineering Contradiction:
Improveblade accessibilityVSAvoidcontamination risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Individual blade compartments isolate each blade from contaminants while maintaining easy access. The sealed cavity structure prevents contact between blades and inappropriate materials, yet the overall package can be opened to retrieve blades as needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blade can be removed from its protective cavity compartment when needed, allowing the rest of the package to remain sealed and protected. This enables selective access to individual blades while maintaining protection for remaining blades against contamination.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If blades are handled frequently for replacement, then productivity is improved, but blade damage and wear worsen

Engineering Contradiction:
Improveblade replacement efficiencyVSAvoidblade service life
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Multiple blades are pre-packaged together in a single unit, allowing rapid replacement of entire sets rather than individual blades. The package is prepared in advance with blades in protective cavities, enabling quick exchange without handling each blade separately, thus reducing premature wear from frequent individual handling.

Inventive Principle:
Principle #10Preliminary action

AI summary

A flexible package (10) for cutting blades. A flexible first layer (12) has at least one cavity (22) formed therein to form a base (20) for receiving a cutting blade (24). A flexible second layer (14) is arranged over the base and proximate the base. A seal (26) is formed about the periphery of each cavity to encapsulate a cutting blade placed into the cavity, the seal being formed by applying a predetermined combination of heat and pressure to selected portions of the second layer to cause adhesive (16) thereon to selectively bond to the base. Movement of each encapsulated cutting blade is deterred during transport and handling by the cavity in cooperation with the seal and the second layer, the blades becoming movable within the cavity when the seal is broken.
