Solution Overview

Problem

Existing pharmaceutical packaging does not efficiently protect and identify multiple doses of pharmaceuticals, making it difficult for users to differentiate and dispense them accurately.

Innovation Solution

A blister package with a body containing pockets arranged in specific orientations and a top seal that interfaces with the body, providing visual indicators and facilitating easy identification and dispensing of multiple doses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pharmaceutical packaging is used, then the packaging structure is simple, but the protection and identification of multiple doses is insufficient

Engineering Contradiction:
Improveprotection and identification of multiple dosesVSAvoidpackaging structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging is divided into multiple pockets within the blister body, each pocket containing a separate pharmaceutical dose. This segmentation allows multiple doses to be protected and identified individually while maintaining a single integrated packaging structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pockets are arranged in specific three-dimensional orientations (parallel and perpendicular arrangements) within the blister body, creating spatial differentiation that enables easy visual identification and differentiation of multiple doses without increasing packaging complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If multiple doses are packaged together, then the quantity of pharmaceuticals is increased, but the ease of identification and dispensing is reduced

Engineering Contradiction:
Improvequantity of pharmaceuticalsVSAvoididentification and dispensing
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

Each pharmaceutical dose is separated into its own pocket, allowing users to easily identify and dispense individual doses while maintaining the benefit of multiple doses in a single package. The pockets are designed to be visually distinguishable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pockets are arranged in asymmetric patterns (parallel and perpendicular orientations) that create visual differentiation between doses, making it easy for users to identify and locate specific doses for dispensing.

Inventive Principle:
Principle #4Asymmetry

3Ease of operation

If the pockets are arranged in specific orientations, then the ease of identification is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
ImproveidentificationVSAvoidpocket arrangement precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The pocket arrangement is segmented into distinct parallel and perpendicular groups, creating clear visual patterns that are easy to identify. This segmentation simplifies manufacturing by using repetitive, standardized pocket formations rather than requiring complex precise positioning of each individual pocket.

Inventive Principle:
Principle #1Segmentation

AI summary

A blister package is disclosed herein. The blister package includes a body, a plurality of pockets, and a top seal. The body has a top surface and a bottom surface opposite the top surface. The plurality of pockets is formed in the body. Each of the plurality of pockets extend below the top surface of the body. Each pocket of the plurality of pockets is configured to hold a pharmaceutical. The plurality of pockets is arranged in a manner that defines at least one dose. The plurality of pockets for the at least one dose includes a first pocket in parallel with a second pocket, and a third pocket perpendicular to the first pocket and the second pocket. The top seal is configured to interface with the body. The top seal is configured to hold the pharmaceutical in each respective pocket.
