Trigger Spray Dispenser for Continuous Fabric Refreshening Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric refreshening products with aerosol or trigger sprayers are difficult to use on large fabric-covered surfaces like beddings, mattresses, and carpets, as they require multiple sprays, provide uneven coverage, and take a long time to dry, leading to incomplete deodorization and refreshening.
Innovation Solution
A packaged fabric refreshening product with a manually activated trigger-type spray dispenser that continuously dispenses a liquid composition containing 1-5 wt% cyclodextrin for at least 0.4 seconds, ensuring efficient and uniform coverage of large surfaces, allowing immediate usage and enhanced odor control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional aerosol or trigger sprayers are used to treat large fabric surfaces, then the product can be applied to fabric surfaces, but the treatment requires 20 or more sprays to cover the entire surface, making it slow and exhausting
Solution Approach 1:
The spray mechanism is segmented into multiple nozzles arranged in a specific pattern, allowing simultaneous coverage of multiple areas on the fabric surface with a single trigger pull, thereby reducing the number of sprays needed from 20+ to just a few sprays
Solution Approach 2:
Multiple spray nozzles are merged into a single dispensing unit that operates with one trigger mechanism, combining the functionality of multiple sprayers into one device to treat large fabric surfaces efficiently without requiring multiple separate spraying actions
2Ease of operation
If conventional sprayers dispense fabric refreshening products, then the fabric surface receives treatment, but the coverage is uneven with some spots dry and untreated while others are soaking wet
Solution Approach 1:
The spray nozzles are positioned at different locations and angles within the dispensing unit, with each nozzle targeted to cover a specific local area of the fabric surface, ensuring that every spot receives appropriate coverage without over-saturation or dry patches
Solution Approach 2:
The spray pattern is designed to distribute liquid across the fabric surface in a two-dimensional pattern rather than a single-point application, with nozzles arranged to create overlapping spray cones that collectively cover the entire treatment area uniformly
3Productivity
If conventional sprayers apply liquid fabric refreshening composition, then the fabric surface is treated, but the wet spots take a while to dry, preventing immediate use of the household items
Solution Approach 1:
The spray application uses a continuous, controlled flow of liquid composition that is optimized to provide sufficient coverage while maintaining rapid evaporation characteristics, allowing the fabric surface to be treated and immediately used without prolonged drying time
Solution Approach 2:
The liquid composition parameters are formulated to achieve optimal balance between coverage and drying speed, with the spray mechanism delivering the composition in a manner that promotes rapid evaporation while still providing effective treatment of the fabric surface
4Object-generated harmful factors
If conventional sprayers treat fabric surfaces with intermittent bursts, then the fabric receives treatment, but the untreated dry spots continue to emit malodors, limiting the overall deodorizing and refreshening effect
Solution Approach 1:
The multi-nozzle arrangement segments the treatment coverage into multiple overlapping zones that collectively eliminate all dry spots on the fabric surface, ensuring complete coverage and preventing any untreated areas where malodors could persist
Solution Approach 2:
The spray pattern design converts what would normally be waste liquid at the edges of spray cones into beneficial overlapping coverage areas, where the spray patterns of adjacent nozzles intersect to ensure complete coverage and eliminate any potential dry spots that would allow malodor emission

AI summary
A packaged fabric refreshening product for refreshening a fabric surface and reducing odor therefrom includes a liquid fabric freshening composition and a spray dispenser for dispensing the liquid fabric freshening composition. The liquid fabric freshening composition includes a liquid carrier and from 1 wt % to 5 wt % of cyclodextrin. The spray dispenser is a manually activated trigger-type spray dispenser, which, upon activation by a single movement of a trigger mechanism, is capable of continuously dispensing the liquid fabric freshening composition for a duration of at least 0.4 seconds. An effective amount of such liquid fabric freshening composition can be sprayed through such manually activated trigger-type spray dispenser onto a fabric surface, such as those on beddings, mattresses, sofas or carpets, which that is substantially planar with a minimal dimension of no less than 0.6 meters.
