Wipes dispenser nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for wet wipes often fail to effectively retain moisture and prevent liquid from spraying when wipes are pulled out, leading to dryness and inefficiency in dispensing.
Innovation Solution
A dispensing nozzle made of resilient material with a fluid retaining member having a sloped surface, integrated with the nozzle, which traps and holds liquid, ensuring re-wetting of wipes and preventing spray expulsion during use, eliminating the need for a re-closable cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple dispensing nozzle is used, then the device complexity is reduced, but moisture retention and spray prevention are insufficient
Solution Approach 1:
The patent combines the dispensing nozzle and fluid retaining member into a single integrated component. The nozzle is made of resilient material that forms both the dispensing opening and the fluid retention structure, eliminating the need for separate parts while achieving both moisture retention and spray prevention functions.
Solution Approach 2:
The nozzle is constructed from resilient material that can deform elastically. This flexibility allows the nozzle to dynamically respond to wipe passage, opening to allow wipe through while closing to trap fluid, and the fluid retaining member uses this flexible property to prevent spray expulsion without requiring rigid mechanical components.
2Reliability
If the outlet opening is small to prevent spray, then spray prevention is improved, but fluid retention and re-wetting capability are reduced
Solution Approach 1:
The patent addresses the fluid quantity issue by adding a vertical dimension to fluid retention. The fluid retaining member extends below the outlet opening level, creating a reservoir space that accumulates squeezed fluid. This vertical extension allows the system to prevent horizontal spray while vertically storing sufficient fluid for re-wetting multiple wipes.
Solution Approach 2:
The resilient material of the nozzle allows dynamic parameter changes in the outlet opening size. The opening can expand to accommodate wipe passage and contract to trap fluid, while the fluid retaining member's capacity parameter ensures sufficient fluid storage. This dynamic parameter adjustment resolves the contradiction between small opening for spray prevention and sufficient fluid quantity for re-wetting.
3Ease of operation
If a resilient material is used for the nozzle, then ease of operation and wipe passage are improved, but manufacturing precision and structural control become more difficult
Solution Approach 1:
The patent utilizes the parameter changes inherent in resilient materials. The nozzle is designed with specific elastic properties that allow it to deform during wipe passage and recover to its original shape. By carefully selecting materials with appropriate elastic moduli and designing the wall thickness parameters, the system achieves both easy wipe passage and sufficient manufacturing precision for reliable fluid retention.
