Solution Overview

Problem

Conventional dispensers are limited to a single chamber and type of product, making them inefficient for packaging multiple substances, such as suntan lotion, hand soap, and bug spray, which requires multiple separate dispensers, leading to bulkiness and difficulty in distribution.

Innovation Solution

A multi-chamber dispenser with a rigid frame that can accommodate multiple removable or permanently attached chambers, allowing for independent or shared dispensing conduits, and a rotatable cap to actuate each chamber for efficient substance dispensing in any orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate dispensers are used to store different substances, then each substance can be stored and dispensed individually, but the overall device becomes bulky and difficult to distribute

Engineering Contradiction:

Improveability to store and dispense multiple substancesVSAvoidbulkiness of dispenser package

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple separate dispensers into a single integrated multi-chamber dispenser unit. Multiple chambers are arranged within a common housing structure, allowing different substances to be stored and dispensed from one compact device rather than carrying multiple separate bottles or containers.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dispenser is designed with universal functionality to handle multiple types of substances through a single device. The common housing and dispensing mechanism serve multiple chambers simultaneously, enabling one dispenser to perform the functions of several separate dispensers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If a single chamber is used in a dispenser, then the dispenser structure is simple, but it can only dispense one type of product requiring multiple separate dispensers

Engineering Contradiction:

Improvesimplicity of dispenser structureVSAvoidability to dispense multiple product types

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The dispenser is segmented into multiple independent chambers within a common housing. Each chamber can be independently filled with different substances and activated, allowing the simple basic structure to be replicated and combined for multi-product functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple chambers are nested within the common housing structure, with each chamber containing its own substance while sharing the external dispenser body. This nesting arrangement allows multiple product types to be accommodated within a single dispenser unit.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A multi-chamber dispenser may be provided and may include one or more chambers that may be removably fastened to a rigid frame and/or one or more chambers that may be permanently fastened to the rigid frame. A chamber may be actuated by rotating a cap, or an actuator, or both, to an application position and then pressing the cap or actuator in order to dispense the substance of one or more chambers. The substance may be dispensed via an independent dispensing conduit or a shared dispensing conduit. The multi-chamber dispenser may operate in any orientation and may operate when less than all of the chambers are fastened to the dispenser.
