Color-Changing Damage Indicating Packaging for Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging for items like condoms, food, and pharmaceuticals lacks reliable evidence of tampering and damage indication, necessitating a solution for track and trace functionality that can detect exposure to oxygen, heat, or pressure.
Innovation Solution
Incorporating a damage indicating material into packaging substrates that changes color when exposed to oxygen, excessive heat, or pressure, combined with anti-counterfeiting taggant materials and track and trace elements, such as QR codes or RFID, to provide tamper evidence and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging is used, then the packaging structure is simple, but it provides no reliable evidence of tampering or damage indication
Solution Approach 1:
The patent incorporates damage indicating materials that change color in response to oxygen exposure, heat, or pressure. These materials are integrated into the packaging layers, providing visible evidence of tampering or damage through color changes from white/colorless to colored states, thereby enhancing reliability without significantly increasing structural complexity
Solution Approach 2:
The patent uses a multi-layer packaging structure where damage indicating materials and track and trace elements are nested between inner and outer wrapper layers. The pocket formed between layers contains these functional elements, allowing integration of multiple functions within a compact nested structure that provides tamper evidence while maintaining reasonable structural complexity
2Reliability
If damage indicating materials are incorporated into packaging, then tamper evidence is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines damage indicating materials, track and trace elements, and packaging layers into a single integrated structure. The materials are applied to or between wrapper layers during the packaging process, merging multiple functions (protection, indication, tracking) into one unified manufacturing process rather than requiring separate assembly steps
Solution Approach 2:
The packaging structure is designed to serve multiple functions simultaneously: the outer and inner wrapper layers provide physical protection, the pocket between layers provides damage indication through color-changing materials, and track and trace elements provide authentication. This multi-functionality is achieved through a single integrated design that can be manufactured in one process
3Reliability
If track and trace elements are added to packaging, then product authentication is enhanced, but device complexity increases
Solution Approach 1:
The patent incorporates track and trace elements such as QR codes, barcodes, or RFID tags into the packaging structure. These elements serve as information carriers that can be read remotely or visually inspected, providing product authentication without requiring complex physical structures. The information is encoded in a simplified form that can be processed by standard scanning or reading devices

Data Source
AI summary
Track and trace packaging is disclosed which may also be damage indicating. Track and trace functionality may be incorporated on, in or near the packaging at various stages of a supply chain. A damage indicating material can be incorporated into a variety of packaging substrates, which may change color when exposed to oxygen, excessive heat and/or excessive pressure. An anti-counterfeiting taggant material may be used to provide track and trace capabilities. Exemplary products with which the present track and trace packaging may be used include packaged condoms, food and beverages, pharmaceuticals, cannabis and the like.
