Reusable Cleaning Liquid Dispensing System With Replaceable Spouted Pouch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for pouched liquid cleaning products, such as spouted pouches, face challenges in providing accurate and controlled dispensing of cleaning liquids, especially when consumers need to dispense small amounts repeatedly over time, as the flexible pouches can be unwieldy and difficult to pour from.
Innovation Solution
A re-usable dispensing system comprising a rigid container with a replaceable spouted pouch, where the pouch spout and container have engagement members that establish fluid communication, allowing for precise dispensing of cleaning liquids from a flexible pouch body, enabling controlled pouring into small locations or machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a flexible spouted pouch is used for dispensing cleaning liquid, then material usage is reduced and environmental friendliness is improved, but controlled dispensing becomes difficult due to the unwieldy nature of the flexible body
Solution Approach 1:
The system is divided into two functional segments: a flexible pouch for material containment and a rigid container for controlled dispensing. The pouch body remains flexible to minimize material usage, while the rigid container portion provides structural support for accurate pouring control.
Solution Approach 2:
The flexible pouch and rigid container are merged into a single hybrid structure where the pouch integrates with the container body. This combination allows the structure to benefit from both the material efficiency of flexible packaging and the dispensing control of rigid containers.
2Ease of operation
If a rigid container is used for dispensing cleaning liquid, then controlled pouring is achieved, but material usage increases and environmental friendliness decreases
Solution Approach 1:
The container is segmented into a rigid portion for structural support and dispensing control, and a flexible pouch portion for material containment. This segmentation allows each material type to be used only where its properties are most beneficial.
Solution Approach 2:
Different regions of the packaging have different material properties: the lower pouch portion is flexible to reduce material usage, while the upper container portion is rigid to provide controlled pouring. Each local region has the quality needed for its specific function.
3Loss of substance
If a flexible pouch is used, then material usage is minimized, but the structure becomes unwieldy and difficult to handle for repeated small amount dispensing
Solution Approach 1:
The packaging is segmented into flexible and rigid portions, with the rigid container providing structural stability for handling and repeated dispensing operations, while the flexible pouch minimizes material usage.
Solution Approach 2:
The packaging uses a composite structure combining flexible and rigid materials in a single unit. This composite approach allows the structure to exhibit both the material efficiency of flexible packaging and the structural stability of rigid containers.
