Solution Overview

Problem

Consumer products packaged in plastic containers often end up in landfills, contributing to environmental waste, and while refills are a sustainable option, they require effort and awareness from consumers, who may not find them convenient or attractive.

Innovation Solution

A refill container system featuring a thin-walled or flexible product chamber within a rigid outer shell container, supported by a fitment that allows easy display and use, minimizing material usage and environmental impact, with a destructive cover for easy access and a snap-fit closure for convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid plastic containers are used for consumer products, then product protection and durability are improved, but environmental waste and landfill contribution increase

Engineering Contradiction:
Improveproduct protectionVSAvoidenvironmental waste
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The packaging system is divided into two segments: a reusable rigid outer container and a disposable inner refill pouch. The rigid container maintains product protection and durability, while the flexible refill pouch contains the consumable product, separating the protective function from the consumable function to reduce overall waste.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible refill pouch is nested inside the rigid outer container. This allows the refill to be contained within the protective structure during storage and transport, then removed and inserted into a refillable dispensing container, maximizing the utility of the rigid container while minimizing material usage for the refill portion.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Loss of substance

If refill containers are provided with minimal packaging, then material usage and environmental impact are reduced, but consumer convenience and ease of use deteriorate

Engineering Contradiction:
Improvematerial usageVSAvoidconsumer convenience
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The refill pouch is nested within the rigid outer container, which provides structural support and protection during shipping. The rigid container includes an integrated dispensing mechanism that remains after the refill is inserted, providing ease of use without requiring the refill itself to be rigid or complex.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The rigid outer container serves as an intermediary between the minimal-packaging refill pouch and the consumer's dispensing needs. It provides the structural support, opening mechanism, and user interface that the flexible pouch alone cannot provide, while the pouch provides the actual product with minimal packaging.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Weight of moving object

If thin-walled flexible product chambers are used, then material weight and environmental impact are minimized, but structural support and stability worsen

Engineering Contradiction:
Improvebottle wall weightVSAvoidstructural support
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The structural support function is segmented from the product-containing function. The rigid outer container provides all necessary structural support, while the thin-walled flexible pouch only needs to contain the product, allowing it to be made from minimal material while maintaining overall system strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The product chamber is made from a flexible thin-walled pouch that can be compressed and deformed during dispensing. This flexible structure is supported by the rigid outer container, allowing the use of minimal material for the product-containing element while maintaining structural integrity through the rigid support structure.

Inventive Principle:
Principle #30Flexible shells and thin films

4Adaptability or versatility

If refills require consumer effort and awareness for proper use, then recycling and re-use sustainability are improved, but consumer acceptance and willingness to use deteriorate

Engineering Contradiction:
Improverecycling capabilityVSAvoidconsumer acceptance
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system is designed to be self-explanatory and self-servicing. The rigid outer container clearly indicates how to open and refill it, and the refill pouch is designed to be easily inserted and removed. The integrated dispensing mechanism automatically manages the refilling process, reducing the cognitive load and effort required from consumers while maintaining sustainability.

Inventive Principle:
Principle #25Self-service
