Solution Overview

Problem

Existing liquid collecting devices, such as those for body fluids, are cumbersome and inefficient due to the need for separate components like funnels and storage containers, making the collection process tedious and costly.

Innovation Solution

A liquid collecting device with a collecting container featuring a diversion cavity and annular jacket cavities for storing storage liquid, where the jacket cavities extend along the axial direction of the diversion cavity and have inflow and outflow ports, allowing for dual functions of diverting and storing liquids, thereby simplifying the operation by eliminating the need for a separate storage container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate components (funnel, collecting tube, storage container) are used for liquid collection, then each component can perform its specific function, but the operation becomes tedious and the device complexity increases

Engineering Contradiction:

Improvefunctional performanceVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the funnel, collecting tube, and storage container into a single integrated collecting container. The diversion cavity acts as the funnel for receiving body fluid, the connecting cavity serves as the collecting tube for liquid flow, and the storage cavity functions as the storage container. This merging eliminates the need for multiple separate components while maintaining all necessary functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The collecting container is designed with multi-functionality, where a single structure performs multiple roles: the diversion cavity receives and directs body fluid, the connecting cavity transports the liquid, and the storage cavity holds the collected sample. This universal design allows one component to replace several specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate components are used for liquid collection, then functional requirements are met, but the collection process becomes time-consuming and productivity decreases

Engineering Contradiction:

Improvecollection accuracyVSAvoidcollection efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

By merging the funnel, collecting tube, and storage container into one integrated structure, the patent enables the user to complete the entire collection process in a single continuous action. The user simply needs to spit into the diversion cavity, and the liquid automatically flows through the connecting cavity into the storage cavity, eliminating multiple manual steps and significantly improving collection efficiency.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If separate components are used for liquid collection, then each component can be optimized independently, but the overall device cost increases

Engineering Contradiction:

Improvecomponent optimizationVSAvoidmaterial consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent reduces material consumption by combining multiple components into a single collecting container. Instead of requiring separate materials for the funnel, collecting tube, and storage container, the integrated design uses one continuous structure, thereby reducing the total quantity of material needed while maintaining all necessary functions.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If a single integrated container is used for both diversion and storage, then operation is simplified and efficiency improves, but the device must perform multiple functions simultaneously

Engineering Contradiction:

Improveoperation simplicityVSAvoidfunctional versatility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The collecting container is designed with internal cavities that provide different functions: the diversion cavity for receiving body fluid, the connecting cavity for liquid flow, and the storage cavity for holding the collected sample. This multi-functional design allows a single component to perform multiple operations, simplifying the user experience while maintaining functional versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The single collecting container is segmented into multiple internal cavities, each optimized for its specific function. The diversion cavity has a wider opening for receiving liquid, the connecting cavity provides a flow path, and the storage cavity holds the final sample. This segmentation allows each region to be optimized for its purpose while remaining part of a unified structure.

Inventive Principle:

Principle #1Segmentation
