Solution Overview

Problem

Current packaging designs for particulate laundry scent additives are prone to dosing cup separation during handling, leading to incomplete products, potential spills when consumers test the scent, and inconvenience in dispensing with three separate elements, which results in financial losses and user dissatisfaction.

Innovation Solution

A package design featuring a container with a closure and dosing cup secured by a shrink sleeve, allowing the dosing cup to be securely attached and providing a vent opening for scent sampling without opening the package, enabling two-handed dispensing and preventing spills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the dosing cup is releasably engaged with the closure, then the consumer can remove the dosing cup for dispensing, but the dosing cup may become separated during shipping or handling

Engineering Contradiction:
Improvedosing cup removal for dispensingVSAvoiddosing cup attachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The dosing cup is pre-engaged with the closure in a secured state during manufacturing, and the consumer performs the releasing action only when needed for dispensing. This preliminary engagement ensures the dosing cup remains attached during shipping and handling, while still allowing easy removal at the point of use.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the closure is opened to smell the product, then the consumer can verify the scent, but the product may spill or be exposed to the environment

Engineering Contradiction:
Improvescent sampling capabilityVSAvoidproduct spillage
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The dosing cup is extracted from the sealed container environment and provided with a vent opening that allows air (and scent) to pass through while retaining the particulate laundry scent additive. This enables the consumer to smell the product by simply opening the dosing cup or creating pressure differential, without opening the main closure and risking product spillage.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If three separate elements (container, closure, dosing cup) are handled during dispensing, then each component can be optimized independently, but the consumer requires three hands or complex manipulation

Engineering Contradiction:
Improvecomponent optimizationVSAvoiddispensing operation simplicity
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The dosing cup and closure are merged into a single assembled unit where the dosing cup is releasably engaged with the closure. This merging allows the consumer to handle them as one component during dispensing operations, simplifying the user experience while maintaining the manufacturing advantages of having separate, optimizable parts.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If the vent opening is large enough for scent sampling, then the consumer can smell the product easily, but the particulate laundry scent additive may escape through the vent opening

Engineering Contradiction:
Improvescent sampling easeVSAvoidparticulate additive escape
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The vent opening is designed with specific local dimensions that are optimized for the dual function of allowing air and scent molecules to pass through while being small enough to retain the larger particulate laundry scent additive. This local quality control at the vent opening enables effective scent sampling without product loss.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design enhances robustness, prevents dosing cup separation, allows scent sampling without opening the package, and simplifies dispensing with two hands, reducing product loss and improving consumer experience.
