Solution Overview

Problem

The challenge in storing and transporting food in Gastronorm containers is the risk of malicious contamination, which is not easily detectable by the customer, as existing vacuum systems can be tampered with to create a false vacuum, masking potential contamination.

Innovation Solution

A Gastronorm container with a vacuum-tight lid and a vacuum valve is equipped with a security label that cannot be removed without destruction, ensuring the vacuum valve remains sealed and detectable, even if attempted to be opened or tampered with, using a forgery-proof label only available to the manufacturer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a vacuum valve is provided on the Gastronorm container to create and release vacuum, then shelf life is extended and food preservation is improved, but the risk of malicious contamination increases as the valve can be tampered with to introduce contaminants

Engineering Contradiction:
Improveshelf lifeVSAvoidcontamination risk
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

A security label is introduced as an intermediary element between the customer and the vacuum valve. This label covers the valve opening and can only be removed by destroying it, serving as a mediator that prevents direct access to the valve while allowing legitimate vacuum operations. The label acts as a security barrier that detects and prevents malicious tampering attempts.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the vacuum valve is covered with a security label that cannot be removed without damage, then contamination risk is reduced and security is improved, but the complexity of the container system increases

Engineering Contradiction:
Improvefood safetyVSAvoidcontainer system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The security label is designed as a disposable, low-cost component that is applied to the container by the manufacturer and remains on the container throughout storage and transport. The label is intended to be destroyed (removed) only at the point of use by the customer, at which point its protective function is no longer needed. This approach provides high security at minimal cost and complexity.

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

3Difficulty of detecting and measuring

If a security label is applied to the vacuum valve, then any attempt to open or tamper with the container becomes detectable, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvetamper detectionVSAvoidmanufacturing process
Core Design Contradiction:
Difficulty of detecting and measuringVSEase of manufacture

Solution Approach 1:

The security label is applied to the vacuum valve during the manufacturing process, before the container is sealed and before it leaves the factory. This preliminary action ensures that the label is already in place and provides security from the moment the container is filled and vacuumed. The label application is integrated into the existing manufacturing workflow, requiring minimal additional steps.

Inventive Principle:
Principle #10Preliminary action
