Fluid Dispenser Barrier Envelope for Trim Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispenser assemblies with internal trim often experience physico-chemical interactions that alter the fluid's composition and properties, making it difficult to maintain the integrity of the fluid, especially when the receptacle has a small opening, and they lack an attractive and cost-effective design.
Innovation Solution
A fluid dispenser assembly featuring a transparent or translucent receptacle with an opaque internal trim and a barrier envelope that separates the fluid from the trim, using a flexible pouch or coating to prevent contact and maintain the fluid's integrity, while allowing the trim to be visible for aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If internal trim is disposed in the inside space of the receptacle, then the appearance of the dispenser assembly is enhanced and made more attractive, but physico-chemical interactions occur between the fluid and the internal trim which alter the fluid's composition and properties
Solution Approach 1:
The internal trim is segmented from the fluid contact zone by introducing a barrier envelope (pouch) that contains the fluid. This segmentation allows the trim to remain visible through the transparent receptacle while physically separating it from the fluid, preventing physico-chemical interactions and maintaining fluid composition stability.
Solution Approach 2:
A barrier envelope (pouch) is introduced as an intermediary element between the internal trim and the fluid. This mediator prevents direct contact between the trim and fluid, blocking physico-chemical interactions while allowing the trim to maintain its aesthetic function visible through the transparent receptacle walls.
2Stability of the object's composition
If a barrier envelope is introduced to separate the fluid from the internal trim, then the fluid's integrity is maintained, but the device complexity increases
Solution Approach 1:
A flexible pouch (thin film barrier) is used as the envelope to separate the fluid from the internal trim. This flexible shell provides an effective barrier against physico-chemical interactions while being simple to manufacture, assemble, and cost-effective, thus minimizing the increase in device complexity.
3Volume of moving object
If the receptacle has a small opening, then the dispenser assembly presents a compact design, but it becomes difficult to insert and deploy the barrier envelope inside the internal trim
Solution Approach 1:
The barrier envelope is designed with dynamic properties - it can be compressed into a compact form for insertion through the small opening, then expanded to its full functional shape inside the receptacle. This dynamic transformation capability allows easy assembly despite the small opening size.
Solution Approach 2:
The flexible pouch can be folded or rolled into a compact configuration that fits through the small opening of the receptacle, then deployed to unfold and occupy the necessary space inside the internal trim, solving the assembly difficulty associated with small openings.
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
The solution effectively prevents physico-chemical changes in the fluid, maintains its integrity, and provides an attractive, cost-effective, and easy-to-manufacture dispenser assembly, even with small openings, ensuring the fluid's quality and appearance are preserved.
Implementation Method 1
a barrier envelope for containing the fluid, said envelope being disposed inside the internal trim so that the fluid is not in contact with said internal trim
Implementation Method 2
the receptacle is made of a transparent or translucent material, such as glass, so that the internal trim is visible through the receptacle
Implementation Method 3
the internal trim is opaque so as to mask at least some, and preferably all, of said barrier envelope

AI summary
A fluid dispenser assembly includes an outer receptacle with an opening, the receptacle including an inside wall defining an inside space; internal trim disposed in the inside space; a dispenser member, such as a pump, for dispensing the fluid; and a barrier envelope for containing the fluid, the envelope being disposed inside the internal trim so that the fluid is not in contact with said internal trim. The receptacle is made of a transparent or translucent material, such as glass, so that the internal trim is visible through the receptacle, and the internal trim is substantially opaque so as to mask at least some, and preferably all, of the barrier envelope.
