Fluid dosing substrate dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wipe dispensing systems face issues such as wipe drying out, non-uniform saturation, chemical interaction leading to efficacy loss, lack of flexibility in chemical formulations, and inflexibility in fluid combinations, resulting in inefficient and costly cleaning solutions.
Innovation Solution
A fluid reservoir with multiple modes of operation and a mobile substrate dispenser that allows selective dosing and dispensing of substrates, integrated with a smart cart system for modular adaptability, enabling on-demand fluid application and substrate advancement based on user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If substrates are pre-dosed with fluid in sealed packaging, then the substrate is ready for immediate use, but the fluid may evaporate or the substrate may dry out over time
Solution Approach 1:
The system separates the substrate storage from the fluid reservoir. The substrate is stored in a dispenser while the fluid is stored in a separate refillable reservoir. The substrate is only contacted with fluid at the moment of dispensing, preventing evaporation and drying out issues that occur in pre-dosed sealed packaging.
Solution Approach 2:
The substrate is prepared in advance and stored in the dispenser, but the fluid application is delayed until the moment of use. The system pre-positions the substrate without pre-applying the fluid, allowing the substrate to remain ready for use while avoiding the fluid retention problems of pre-dosed systems.
2Adaptability or versatility
If multiple pre-dosed substrates with different fluids are carried, then different surface cleaning needs are met, but the cleaning cart becomes overloaded and complex to manage
Solution Approach 1:
The substrate dispenser is designed to work with multiple different fluid reservoirs. A single substrate dispenser unit can accommodate various fluids (glass cleaner, disinfectant, all-purpose cleaner) by simply changing the reservoir, eliminating the need to carry multiple separate dispensers or pre-dosed substrate packages for different surfaces.
Solution Approach 2:
The system allows dynamic reconfiguration by enabling easy swapping of fluid reservoirs. The user can adapt the cleaning setup to different surface needs by replacing the fluid reservoir while keeping the same substrate dispenser, providing versatility without increasing overall system complexity.
3Reliability
If substrates are stored in sealed packaging to prevent drying, then substrate moisture is preserved, but wipes may attach to each other and become inseparable
Solution Approach 1:
The system separates substrate storage from fluid application. Substrates are stored dry in the dispenser and only contacted with fluid during the dispensing process. This eliminates the problem of wipes sticking together in sealed packaging while ensuring each wipe is properly saturated with fluid when needed.
Solution Approach 2:
The dispensing mechanism acts as an intermediary between the stored substrate and the fluid reservoir. The substrate passes through this intermediary where fluid is applied in controlled amounts, preventing the substrate from being stuck in a state where wipes are both moistened and stuck together as in sealed pre-dosed packages.
4Adaptability or versatility
If cleaning services carry a variety of cleaning solutions for different surfaces, then all surface types can be cleaned, but the variety of solutions creates burden and complications
Solution Approach 1:
The substrate dispenser serves as a universal platform that can accommodate multiple different fluid reservoirs. Instead of needing separate dispensers or remembering which pre-dosed substrates are for which surfaces, the user simply selects the appropriate fluid reservoir and uses it with the same substrate dispenser, simplifying the cleaning process across multiple surface types.

AI summary
A fluid dispenser comprises a housing, a first fluid interface on a first portion of the housing for attachment of a fluid applicator, and a second fluid interface on a second portion of the housing. The second fluid interface is configured to move from a first position in sealing engagement with the second portion of the housing to a second position for fluid connection of an interior of the housing to a fluid applicator system of a fluid dosing substrate dispenser when the fluid dispenser is fluidly connected to the fluid dosing substrate dispenser.
