Pump Device with Equidistant Flow Paths for Deodorant Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pumps are not commonly used for delivering deodorant products, particularly in gel or liquid forms, and there is a desire to maintain a user's customary application experience while providing a new delivery method, especially in conjunction with pouches.
Innovation Solution
A fluid delivery package design featuring a package shell, a pump, and a flexible pouch with an equidistant product flow path defined by a package head, ensuring even distribution of the product through multiple outlets, allowing for consistent application across a surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pump is used to deliver gel or liquid deodorant, then a new delivery method is provided, but the device complexity increases compared to traditional screw-push mechanisms
Solution Approach 1:
The pump mechanism is designed to work with multiple product types (gel, liquid deodorant) and can be integrated with different package configurations (pouch, bottle), making it a universal delivery system that replaces multiple specialized mechanisms with one versatile component
Solution Approach 2:
The pump is nested within the package structure, with the pump chamber containing the product and the pump mechanism integrated into the package head, creating a compact nested arrangement that reduces overall device complexity while maintaining pump functionality
2Manufacturing precision
If multiple product outlets are used for even distribution, then product distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The flow path is designed with asymmetric channel configurations that compensate for varying distances from the pump outlet to different product outlets, ensuring uniform product distribution across all outlets by balancing the flow dynamics through asymmetric geometric design
Solution Approach 2:
The flow path is engineered to create equipotential flow conditions where each product outlet receives equal flow rate, using strategically designed channel dimensions and positions to ensure that all outlets are effectively at equal potential for product delivery despite their spatial arrangement
3Volume of moving object
If the pump is integrated with the package head, then the device compactness is improved, but the ease of operation may be reduced
Solution Approach 1:
The package is segmented into distinct functional modules: the pump mechanism integrated into the package head, the product-containing pump chamber, and the product outlets in the package head, allowing each component to be optimized independently while maintaining overall compactness
Solution Approach 2:
An actuation button or lever serves as an intermediary between the user and the pump mechanism, providing a simple and intuitive interface that maintains ease of operation while the pump itself remains integrated within the package head structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and even dispensing of deodorant products, maintaining user experience while introducing a new delivery method that ensures consistent product distribution through equidistant flow paths, enhancing usability and aesthetic appeal.
Implementation Method 1
a pump in communication with a flexible package—such as a flexible pouch—containing a product such that the pump may pump the product out of the flexible package and through a pump discharge passage
