Solution Overview

Problem

Existing package closing systems with frangible radiofrequency identification labels face issues of accidental breakage when attached externally, and when protected internally or incorporated into seals, they are not destroyed upon opening, potentially facilitating misuse.

Innovation Solution

A package closing system where a frangible radiofrequency identification label is attached to the inner portion of the cover and the outer portion of the seal, ensuring destruction upon opening, utilizing a multilayer seal structure with a metal foil and electromagnetic field for sealing, and a reading device to verify the label's information against a database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the frangible radiofrequency identification label is attached to the outer portion of the cover and the outer portion of the package, then the label is exposed for authentication, but the label is susceptible to accidental breakage

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidaccidental breakage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The frangible radiofrequency identification label is nested within the sealing system, specifically attached to the inner portion of the cover and the outer portion of the seal, placing it inside the sealed space rather than externally exposed. This nesting protects the label from external damage while maintaining its authentication function.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The seal acts as an intermediary structure that holds the frangible label in a protected position. The label is attached to both the cover and the seal, using the seal as a mediator to secure the label within the sealed space, away from external harmful factors.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the radiofrequency identification label is attached to the inner portion of the cover or incorporated into sealing seals, then the label is protected from external exposure, but the label is not destroyed when the package is opened

Engineering Contradiction:

Improveprotection from external exposureVSAvoidauthentication integrity

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The label's state changes dynamically based on package opening. The frangible nature of the label allows it to transition from an intact protected state during sealing to a destroyed state upon package opening, enabling it to serve both protection and authentication destruction functions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The label is pre-positioned within the sealed space during the sealing process, attached to both the cover and the seal. This preliminary positioning ensures the label is protected during sealing but will be destroyed when the seal is broken during package opening.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the frangible label is attached to both the inner portion of the cover and the outer portion of the seal, then the label is protected and destroyed upon opening, but the attachment complexity increases

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidattachment structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The seal serves multiple functions: it seals the package, holds the frangible label in a protected position, and provides an attachment point that ensures label destruction upon opening. By making the seal multi-functional, the system reduces the need for separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A package closure system has a frangible radiofrequency identification label which is protected from the external environment by a cover and the frangible label is damaged preventing its normal operation when the package cover is removed. More specifically, a package closure system has a cover, a metallic induction seal attached to the package nozzle and a frangible radiofrequency identification label in which the frangible radiofrequency identification label is attached directly or indirectly to one of its parts on the inner portion of the cover and on another part on the outer portion of the metallic seal.
