Solution Overview

Problem

Conventional fluid containers face issues such as structural failure, germ transmission, and reduced lifespan due to repetitive deformation and opening, leading to difficulties in controlling fluid flow and increased risk of contamination.

Innovation Solution

A pressurizable fluid container with a plunger mechanism, teeter valve, and adjustable spray nozzle that allows for controlled fluid release through pressurization, reducing the need for tilting or squeezing, and minimizing contact with the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional fluid containers are squeezed or tilted to release fluid, then fluid flow is enabled, but structural failure occurs due to repetitive deformation

Engineering Contradiction:

Improvefluid flow controlVSAvoidcontainer wall structural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The invention divides the fluid release function into separate components: a valve mechanism at the dispensing end that can open/close without deforming the container body. The container structure remains intact while the valve segment handles the operational stress of fluid release.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention replaces the mechanical squeezing/tilting system with a valve-based dispensing system. Instead of deforming the container to release fluid, users activate a valve mechanism that controls fluid flow while the container maintains its structural form.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the container is frequently opened for drinking or cleaning, then fluid access is improved, but germ transmission and contamination increase

Engineering Contradiction:

Improvefluid accessVSAvoidgerm transmission and contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the drinking/cleaning function from the main container opening. A separate dispensing valve system provides fluid access without requiring removal of the cap or direct contact with the container rim, isolating the fluid source from contamination risks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The valve mechanism serves as an intermediary between the user and the fluid. Users interact with the valve rather than directly contacting the container opening or fluid source, reducing transmission of germs and foreign materials.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the container is repeatedly opened and closed, then fluid dispensing is enabled, but product lifespan is reduced due to mechanical stress

Engineering Contradiction:

Improvefluid dispensing capabilityVSAvoidproduct lifespan

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The invention separates the dispensing function into a dedicated valve mechanism that can be opened/closed repeatedly without affecting the main container structure. The container body experiences no mechanical stress from valve operation, preserving its lifespan.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The valve mechanism is pre-configured to handle repeated opening/closing operations. The valve components are designed to withstand mechanical stress from frequent actuation, protecting the overall product lifespan from wear and damage.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If pull-valve or screw-type cap mechanisms are used, then fluid sealing is improved, but damage and loss of parts occur due to constant use

Engineering Contradiction:

Improvefluid sealingVSAvoidpart damage and loss

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention replaces complex mechanical sealing systems (pull-valves, screw caps) with a simpler valve-based dispensing system. The new system maintains fluid sealing through the valve mechanism while eliminating the need for user manipulation that causes part damage or loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The valve mechanism automatically maintains sealing when closed and opens controllably for dispensing. The system self-regulates fluid flow without requiring user intervention that could damage or lose components.

Inventive Principle:

Principle #25Self-service
