Solution Overview

Problem

Existing handling supports for conveying products, particularly in the food industry, lack effective protection against dust and dirt, leading to contamination and spoilage during transportation.

Innovation Solution

A cover made from lightweight, easy-to-produce materials such as LDPE or biodegradable thermoplastic foils with center fold lines, sealed to form interconnected covers that can be easily applied over products on handling supports, preventing contamination and spoilage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If products are transported on handling supports without covers, then physical access is unrestricted and handling is easy, but dust and dirt contaminate the products

Engineering Contradiction:
Improveproduct contaminationVSAvoidphysical access to product
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent uses a flexible cover made from a sheet of material that can be draped over the product on the handling support. This thin film barrier prevents dust and dirt from contaminating the product while remaining easy to apply and remove, thus protecting the product without significantly impeding handling operations.

Inventive Principle:
Principle #30Flexible shells and thin films

2Object-affected harmful factors

If a cover is provided to protect products, then product contamination is prevented, but the cover adds complexity to the handling system

Engineering Contradiction:
Improveproduct contaminationVSAvoidhandling system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The handling system is segmented into distinct components: the handling support, the product, and the removable cover. This segmentation allows the cover to be independently applied and removed without affecting the handling support structure, thereby preventing contamination while minimizing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover is designed as a simple, inexpensive, single-use or limited-use component made from basic sheet material. This disposable approach eliminates the need for complex, expensive, or maintenance-intensive protective systems, preventing contamination without adding significant complexity to the handling system.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If expensive or complex protective measures are used, then product protection is enhanced, but production cost increases

Engineering Contradiction:
Improveproduct protectionVSAvoidproduction cost
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The cover is made from inexpensive sheet material that can be produced at low cost using simple manufacturing processes. This disposable or limited-use cover provides effective product protection without requiring expensive materials or complex manufacturing, thus enhancing product protection while keeping production costs low.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention uses basic sheet material with simple physical properties (flexibility, drapeability) that can be obtained from common, low-cost materials. By relying on simple physical parameters rather than expensive materials or complex structures, the solution achieves effective protection at minimal production cost.

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention pertains to a cover (1) for covering product (13) on a handling support (11) for conveying the product, in particular meat portions, the cover comprising a sheet (2) having a center (4) and fold lines (3) and that is provided in a folded state resulting in a folded sheet in which said sheet is functionally zigzag folded about said fold lines while leaving said center free for positioning said center on a handling support end, said folded sheet having ends (5, 5') at which surfaces of said zigzag folded sheet are attached together (9).
