Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety vacuum packaging methods are insecure regarding authenticity and first-opening guarantees, as they can be easily copied or replaced after initial opening with minimal effort and cost.
Innovation Solution
A method involving a safety vacuum packaging system where particles are fixed in a random immobile state through a vacuum seal, creating a unique fingerprint for authentication, and a computer program product for verifying this state by comparing initial and re-captured images of the particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional safety packaging methods (bar codes, seal closures, liquid coloring) are used, then basic security functions are provided, but the packaging can be easily copied and replaced after initial opening with minimal effort and cost
Solution Approach 1:
The packaging system is segmented into multiple functional components: a container for the product, a separate particle container holding numerous individual particles, and a vacuum seal mechanism. This segmentation allows the security function to be isolated in the particle arrangement while keeping the main packaging structure simple and cost-effective.
Solution Approach 2:
The particles are pre-arranged in a specific random immobile state within the container before sealing. This preliminary arrangement creates a unique fingerprint that is captured and stored for later verification. The action is performed in advance during packaging, enabling security verification without adding complexity to the final product structure.
2Reliability
If particles are fixed in a random immobile state through vacuum sealing, then a unique fingerprint is created for authentication, but the system becomes more complex compared to conventional safety packaging
Solution Approach 1:
The vacuum seal serves dual functions: it seals the packaging container and simultaneously fixes the particles in their random immobile state. The vacuum pressure naturally arranges and immobilizes the particles without requiring additional mechanisms or complex equipment. The system uses the sealing process itself to create the security feature.
Solution Approach 2:
The physical state of the particles is changed from mobile to immobile through the application of vacuum pressure. This parameter change (from atmospheric to vacuum conditions) creates the fixed random arrangement that serves as the security fingerprint, transforming a simple sealing process into a security-critical operation.
3Ease of operation
If conventional sealing methods are used, then packaging closure is achieved, but tampering and replacement cannot be reliably detected
Solution Approach 1:
The system captures an image of the particle arrangement immediately after vacuum sealing and stores it as a reference fingerprint. During verification, a new image is captured and compared against the stored fingerprint. This feedback loop provides automatic tamper detection: if the particle arrangement has changed (indicating opening or tampering), the system immediately identifies the discrepancy and alerts to the security breach.

Function Achieved in This Case
Enhances the security of the packaging by ensuring that any changes, such as opening or tampering, can be detected through the comparison of stored and re-captured particle states, thereby protecting the integrity of the contents.
Implementation Method 1
The safety vacuum packaging, in particular the interior space of the container, is vacuumed via a vacuum seal, whereby the plurality of particles is fixed in a random immobile state

AI summary
A method for closing and securing a safety vacuum packaging in which an object to be secured and a plurality of particles are arranged in an interior space of a container of the safety vacuum packaging. Subsequently, the safety vacuum packaging is vacuumed via a vacuum seal, and the plurality of particles is fixed in a random immobile state. The safety vacuum packaging is closed, and the random immobile state of the particles is captured. The captured random immobile state of the particles is stored for later comparison.
