Solution Overview

Problem

Conventional fluid dispensers often face issues with compact design, ease of container replacement, and efficient fluid dispensing, particularly in maintaining a water-tight seal and minimizing waste, especially when dealing with foamy or viscous products.

Innovation Solution

The fluid dispenser incorporates a pump and adapter assembly with a resilient spring mechanism and angled receptacle, allowing for a compact design, easy container replacement, and efficient dispensing, using a push bar-type actuator that directly engages the pump nozzle without additional linkage, ensuring reliable operation and reduced manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a conventional pump actuator with additional linkage is used, then the pump can be actuated, but the device complexity increases and manufacturing cost increases

Engineering Contradiction:
Improveactuator linkage complexityVSAvoidpump actuation reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent removes the intermediate linkage mechanism from the pump actuator, directly coupling the push bar to the pump nozzle. This extraction of unnecessary components simplifies the device structure while maintaining reliable pump actuation through direct mechanical contact.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a complex linkage system to transmit motion from the push bar to the pump, the invention inverts the approach by having the push bar directly engage and move the pump nozzle. This reversal of the actuation mechanism eliminates intermediate components and reduces overall system complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If the container receptacle is positioned at a standard angle, then the housing structure is simplified, but the ease of emplacing the container decreases

Engineering Contradiction:
Improveease of container emplacementVSAvoidreceptacle structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs an asymmetric receptacle design where the container receiving area is angled differently from the main housing structure. This asymmetric configuration facilitates easier container insertion by aligning with natural handling orientations while maintaining overall structural integrity.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The invention introduces an angled receptacle that creates a dimensional variation in the housing structure. By angling the receptacle relative to the main housing body, the design provides ergonomic advantages for container placement without significantly complicating the overall manufacturing process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If the pump and adapter assembly is designed for compactness, then the dispenser size is reduced, but the ease of container replacement may be compromised

Engineering Contradiction:
Improvedispenser sizeVSAvoidcontainer replacement ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent divides the container system into separable components: a reusable pump and adapter assembly and replaceable containers. This segmentation allows the compact pump unit to remain permanently installed in the reduced-size dispenser while enabling easy container replacement through simple attachment and detachment mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pump and adapter assembly serves multiple functions: it acts as the dispensing mechanism, provides the container interface, and maintains the compact dispenser structure. This multi-functionality allows the compact design to support easy container replacement without requiring additional components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
