Solution Overview

Problem

Conventional pots do not effectively separate liquids from solids during pouring, leading to inconvenience and potential choking hazards when solids are poured along with the liquid.

Innovation Solution

A pot design featuring a ring-shaped filter plate positioned below the pouring opening, which allows liquids to pass through while blocking solids, ensuring they are retained within the pot body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional pot without filter plate is used, then the structure is simple and easy to manufacture, but solids are poured out together with liquid causing inconvenience and potential choking hazards

Engineering Contradiction:
Improveconvenience of drinkingVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pot is segmented into functional zones by introducing a filter plate that divides the pouring path into liquid-passing and solid-blocking sections. This segmentation allows the pot to simultaneously achieve simple overall structure while providing effective solid-liquid separation at the critical pouring point.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A filter plate is introduced as an intermediary component between the liquid and the user. This intermediary element selectively allows liquid to pass through while blocking solids, thereby solving the choking hazard problem without requiring complex mechanical separation systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a filter plate is added to separate solids from liquids, then solids are effectively blocked, but the device structure becomes more complex

Engineering Contradiction:
Improvesolid-liquid separation effectivenessVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The filter plate utilizes porous material properties to achieve solid-liquid separation. The porous structure naturally filters solids from liquid through size exclusion, providing reliable separation without requiring complex mechanical moving parts or additional control mechanisms.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The filter plate is strategically positioned only at the pouring opening where solid-liquid separation is most critical. This localized application of filtering function provides maximum separation effectiveness while minimizing the overall structural complexity of the pot.

Inventive Principle:
Principle #3Local quality

3Reliability

If filter plate is positioned below pouring opening, then solids are retained in pot body, but cleaning access may be restricted

Engineering Contradiction:
Improvesolid retentionVSAvoidcleaning accessibility
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The filter plate is designed with dynamic accessibility - while positioned below the pouring opening for effective solid retention, it can be easily removed or accessed when the pot body is inverted or opened. This dynamic access mechanism maintains both solid retention reliability and cleaning ease.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pot body can be inverted or opened to provide access to the filter plate from below, reversing the typical access direction. This inversion approach allows easy cleaning of the filter plate while maintaining its optimal position for solid retention during normal pouring operations.

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

AI summary

A pot is adapted to contain a liquid (21) and separate solids (22) from the liquid (21). The pot includes a pot body (3), a cover unit (4), and a ring-shaped filter plate (5). The pot body (3) defines a receiving space (33) adapted for receiving the liquid (21) therein, and has a top opening (311) and a pouring opening (312) in spatial communication with the receiving space (33). The cover unit (4) includes a cover member (41) removably covering the top opening (311), and an insert member (43) extending downwardly from the cover member (41) into the receiving space (33). The filter plate (5) is disposed in the receiving space (33) at a position below the pouring opening (312), is sleeved on one of a bottom portion of the cover member (41) and a top portion of the insert member (43), and is adapted for filtering out the solids (22) during passage of the liquid (21) therethrough.
