Solution Overview

Problem

Existing package seals do not allow for precise real-time monitoring of when a package is opened, and they lack a simple and effective method for controlling the integrity of the seal beyond visual inspection.

Innovation Solution

A package with a specially designed seal that includes a control component integrated into an irreversibly degradable part, which is anchored to the package and features an electronic unit for detecting degradation and initiating detection means upon seal positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional seals are used for packages, then the seal structure remains simple and easy to manufacture, but the ability to monitor seal integrity in real-time is lost and visual inspection is required

Engineering Contradiction:
Improveseal integrity monitoring precisionVSAvoidseal structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control component is integrated within the degradable part of the seal, creating a nested structure where the detection system is contained inside the seal itself. This allows real-time monitoring capability to be embedded within the existing seal structure without requiring separate external monitoring systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces visual inspection (mechanical/optical system) with an electronic detection system that automatically monitors seal integrity. The electronic unit detects degradation of the control component and transmits this information remotely, substituting human visual inspection with automated electronic sensing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If visual inspection is used to check seal status, then no additional electronic components are needed, but real-time monitoring capability and precise timing information are unavailable

Engineering Contradiction:
Improveseal status information availabilityVSAvoidelectronic unit complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The electronic unit provides continuous feedback on seal integrity status by detecting the state of the control component and transmitting this information to external systems. This feedback mechanism enables real-time monitoring of seal status without requiring physical inspection, automatically informing stakeholders of the package's security state.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the seal uses irreversible degradation to indicate opening, then the seal provides reliable tamper evidence, but the ability to detect precisely when opening occurred is lost

Engineering Contradiction:
Improveopening time detection precisionVSAvoidseal integrity reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The control component is pre-positioned within the degradable part of the seal before the seal is applied to the package. This preliminary setup ensures that when degradation occurs during opening, the electronic detection system is already in place to immediately detect and record the precise moment of opening, capturing timing information that would otherwise be lost.

Inventive Principle:
Principle #10Preliminary action
