Solution Overview

Problem

Conventional wipe dispensing systems face issues such as drying out, non-uniform wipe saturation, chemical interaction leading to efficacy loss, lack of flexibility in fluid formulations, and limited storage duration of fluid-substrate combinations, resulting in wastage and inefficiency.

Innovation Solution

A substrate dispenser that allows on-demand dosing of fluids, featuring multiple fluid reservoirs, a computing system for personalized fluid application, and a substrate advancing mechanism, enabling customizable fluid application patterns and amounts based on user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If substrates are pre-dosed with fluid and stored in sealed packaging, then fluid application is convenient, but fluid evaporates and chemicals interact with substrate over time reducing efficacy

Engineering Contradiction:

Improveconvenience of fluid applicationVSAvoidfluid-substrate efficacy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system separates the substrate storage from the fluid storage, with substrates stored dry in a dispenser and fluids stored separately in replaceable reservoirs. The substrate is only dosed with fluid immediately before use, eliminating long-term contact and chemical interaction while maintaining ease of operation through automated dosing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The substrate is prepared in advance in a dry state and stored ready for use. The fluid is introduced just before the substrate is needed, ensuring maximum efficacy while maintaining convenience through the automated dispensing system that doses the substrate as it is dispensed.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple fluid reservoirs are used for different formulations, then flexibility in fluid choices increases, but device complexity increases

Engineering Contradiction:

Improveflexibility in fluid formulationsVSAvoidnumber of fluid reservoirs

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dispenser is designed with a universal fluid reservoir interface that can accommodate multiple different fluid formulations. The same basic reservoir structure and dosing mechanism work with various fluid types, allowing flexibility in fluid choices without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A fluid dosing substrate dispenser comprises a housing with a first fluid reservoir and/or a first fluid reservoir holder configured to removably receive the first fluid reservoir and a second fluid reservoir and/or a second fluid reservoir holder configured to removably receive the second fluid reservoir. The dispenser includes a substrate advancing mechanism configured to receive substrate from a substrate source and to advance a portion of the substrate through the housing and an application mechanism configured to apply fluid from at least one of the first fluid reservoir or the second fluid reservoir to one or more portions of the substrate. A computing system is configured to select at least one of amount of fluid for application, composition of fluid for application, or portion of the substrate the fluid is applied based on an input received by the computing system indicating the user of the substrate dispenser.
