Solution Overview

Problem

Traditional coffee filters require time-consuming and troublesome steps such as removing and cleaning filter cups and disposing of filter papers, which hinder the efficiency of beverage preparation.

Innovation Solution

A filter container with a main part and a filter piece that allows for easy removal of coffee grounds by keeping unwanted particles within the container, eliminating the need for cleaning and reducing preparation effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional filter paper and filter cup are used, then coffee filtering can be achieved, but the preparation process becomes troublesome and time-consuming due to multiple steps of removing, cleaning, and reinstalling

Engineering Contradiction:
Improvebeverage preparation efficiencyVSAvoidfilter preparation effort
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges the filter cup and filter paper into a single integrated filter container assembly. The filter container includes a cup body with a filter element built-in, eliminating the need to separately handle filter paper and filter cup. This integration allows the entire assembly to be removed and discarded as one unit after use, significantly reducing the number of steps involved in filter preparation and cleanup.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filter container is designed as a separable assembly that can be easily removed from the brewing device as a complete unit. The coupling portion allows for simple detachment, enabling the entire filter container with spent grounds to be disposed of together without requiring separate cleaning operations for the cup and filter media.

Inventive Principle:
Principle #1Segmentation

2Loss of time

If filter paper is used, then coffee grounds can be filtered, but additional time is spent on disposing of filter paper and cleaning the filter cup

Engineering Contradiction:
Improvefilter cleanup timeVSAvoidfilter system structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The filter element is built into the filter container structure, creating a unified assembly where the filtering function and the containment function are combined. This eliminates the need for separate filter paper disposal and cup cleaning operations, as the entire assembly can be removed and discarded together, reducing both time and complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If multiple separate components (filter cup, filter paper) are used, then filtering function is achieved, but the number of handling steps increases

Engineering Contradiction:
Improvefilter installation simplicityVSAvoidpreparation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The filter container integrates the cup body and filter element into a single pre-assembled unit. This merged structure requires only one installation action - placing the entire filter container into the brewing device - eliminating the need to separately install filter paper into the filter cup, thereby reducing both preparation time and operational complexity.

Inventive Principle:
Principle #5Merging (Combining)
