Solution Overview

Problem

Existing blister card packages often face a tradeoff between being child-resistant and senior-friendly/tamperproof, where they may be difficult for seniors to access due to requiring strength, or less secure for children if they are easier to open.

Innovation Solution

A multi-layered blister package design featuring a blister sheet with aligned apertures and removable tabs on a back sheet, which balances child-resistant, senior-friendly, and tamperproof features by allowing controlled access through a combination of foil layers and foldable panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the blister card package requires greater human dexterity and strength to dispense products, then the package provides greater tamperproof features and child safety, but it becomes difficult for senior citizens to access due to lack of strength

Engineering Contradiction:
Improvechild safety and tamperproof featuresVSAvoidaccessibility for senior citizens
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The package is divided into multiple functional layers: a blister sheet containing products, a front sheet with apertures, and a back sheet with foldable panels and tabs. This segmentation allows each layer to contribute differently to security and accessibility, resolving the contradiction between child safety and senior accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The back sheet incorporates foldable panels that can be folded along fold lines to align tabs with access slots. This dynamic mechanism enables the package to transition between a secure closed state (resisting child access) and an accessible open state (allowing senior access through tab manipulation), thereby resolving the strength requirement contradiction.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the blister card package requires less strength to dispense products, then it provides greater simplicity for adults and seniors, but it becomes less tamperproof and easily accessed by children

Engineering Contradiction:
Improvesimplicity for adults and seniorsVSAvoidtamperproof features and child safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The tabs act as intermediary elements between the user and the product. They require minimal strength to manipulate (providing simplicity for seniors) but create a complex interaction sequence that prevents children from easily accessing the product. The tabs mediate between the opposing requirements of ease of operation and security.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The package structure is pre-configured with aligned tabs and access slots that must be manually manipulated in a specific sequence. This preliminary arrangement of components creates an inherent security mechanism that maintains tamperproof features while requiring only simple tab removal for adult access.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the package uses a multi-layered structure with foldable panels and aligned tabs, then it balances child-resistant and senior-friendly features, but it increases device complexity

Engineering Contradiction:
Improvebalancing child-resistant and senior-friendly featuresVSAvoidmulti-layered structure with foldable panels
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The multi-layered structure serves multiple functions simultaneously: the blister sheet contains and protects products, the front sheet with apertures provides viewing and access, the back sheet with foldable panels creates security mechanisms, and the aligned tabs enable controlled dispensing. This multi-functionality justifies the increased structural complexity by resolving the adaptability contradiction.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A multi-layered blister package and assembling method include a blister sheet having a blisters for containing a product therein and an opposing cover surface adjacent to blister openings. The package also includes a front sheet having apertures configured to receive the blisters and a back sheet coupled to at least a portion of the front sheet. The back sheet includes an inner back panel foldably connected to an outer back panel. The inner and outer back panels each include removable tabs each covering an access slot. The tabs and access slots of the inner and outer back panels are in alignment when the inner back panel is folded adjacent to the outer back panel. The cover surface of the blister sheet is positioned adjacent to the inner back panel such that each blister opening is in alignment with the tabs and access slots of the inner and outer back panels.
