Solution Overview

Problem

Existing blister pack storage and dispensing solutions fail to ensure consistent and convenient medication administration, leading to potential non-compliance, medication degradation, and unauthorized access due to improper storage and placement.

Innovation Solution

A vertically mounted, gravity-fed dispensing container with a holder portion for supporting blister packs, a catching container for collecting expelled medications, and a dispensing opening with a valve for controlled release, allowing for convenient storage and administration of medications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If blister packs are stored in inconsistent or inconvenient locations, then storage flexibility is improved, but medication compliance deteriorates and access security worsens

Engineering Contradiction:

Improvestorage flexibilityVSAvoidmedication compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The dispensing container is designed to be mounted in a consistent location (e.g., kitchen wall near food preparation area) and automatically presents medications through gravity-fed mechanisms, requiring no active management from users. The system serves itself by maintaining proper storage conditions and enabling easy dispensing without compromising compliance

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The dispensing container acts as an intermediary between the blister pack and the patient, providing a controlled interface that ensures medications are dispensed only when intended. The container's structured design with designated mounting locations and controlled access points mediates between storage flexibility and compliance reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If blister packs are placed in convenient locations for patient access, then ease of use is improved, but unauthorized access risk increases

Engineering Contradiction:

Improvepatient convenienceVSAvoidunauthorized access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system moves the dispensing action to a different dimensional level by using gravity-fed mechanisms where medications fall through controlled openings. The valve mechanism operates in a separate control dimension, allowing convenient patient access while maintaining security through multi-layered control structures

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Different parts of the dispensing container have different functional qualities: the mounting structure provides security and consistent positioning, the gravity-fed chamber enables easy dispensing, and the valve mechanism provides controlled access. This local differentiation of qualities allows simultaneous achievement of convenience and security

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If medications are stored without consistent location control, then storage adaptability is improved, but medication degradation accelerates

Engineering Contradiction:

Improvestorage location flexibilityVSAvoidmedication stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The dispensing container is designed with built-in protective features from the outset: the mounting structure ensures consistent positioning away from harmful environments, the enclosed structure protects against moisture and contamination, and the gravity-fed design minimizes handling. These beforehand protective measures cushion against degradation risks while maintaining storage flexibility

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A wall mounted vertical, gravity fed dispensing container for use with a blister pack includes a pair of perforated sheets defining a holder portion for receiving and supporting the blister pack while holding the blister pack parallel to the wall. The holder portion is formed as a separate element which can be snapped into the container. The two sheets are hinged at the bottom. Behind the holder portion is a catching container fixed to the holder portion and to the wall such that medication expelled from the blisters through the openings by a manually movable punch is caught in the catching container. A bottom wall of the catching container converges the medications to a bottom chute with a manually movable press lever operating a flap valve to discharge the medications into a cup. A front door covers the holder and the blister pack and contains a receptacle for the punch.
