Solution Overview

Problem

Existing brewing apparatuses are not versatile enough to efficiently infuse tea and brew coffee simultaneously, requiring separate and costly equipment for each purpose.

Innovation Solution

A multipurpose infuser filter strainer comprising a soft sieve, a hard sieve, a top cap ring, a bottom cap ring, and a soft mesh, where the soft sieve has mesh holes smaller than the hard sieve, allowing for both tea infusion and coffee brewing without structural changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single apparatus is designed to serve both tea infusion and coffee brewing, then versatility is improved, but the device complexity increases due to the need for multiple mesh sizes

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The filtering system is divided into three distinct sieve layers with different mesh sizes: a hard sieve with larger mesh holes for tea leaves, and a soft sieve with smaller mesh holes for coffee grounds. This segmentation allows each layer to specialize in filtering specific beverage components, enabling the single apparatus to handle both tea infusion and coffee brewing effectively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The soft sieve is nested within the hard sieve, with the soft sieve positioned inside the hard sieve's cylindrical structure. The bottom cap ring with its center opening allows the soft sieve to be inserted and secured within the hard sieve assembly. This nested configuration maximizes space utilization and enables dual functionality without significantly increasing overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If a soft sieve with small mesh holes is used for coffee brewing, then filtration quality is improved, but the sieve becomes vulnerable to deformation and damage

Engineering Contradiction:
Improvefiltration qualityVSAvoidsieve durability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The soft sieve is placed inside the hard sieve, which acts as a protective outer shell. This nested arrangement provides structural support to the delicate soft sieve before it is subjected to use, preventing deformation and damage. The hard sieve's rigid structure cushions and protects the soft sieve's fine mesh holes from external forces.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The filtering system combines two different sieve materials with distinct properties: a hard, rigid material for the outer sieve that provides structural strength, and a soft, flexible material for the inner sieve that provides fine filtration. This composite approach allows the system to achieve both high filtration quality and structural durability simultaneously.

Inventive Principle:
Principle #40Composite materials

AI summary

A multipurpose infuser filter strainer, configured to infusing tea and making coffee directly without the need of changing its structural arrangement, include a soft sieve defining opposing top opening and bottom opening, a hard sieve surrounding the soft sieve and defining opposing top opening and bottom opening for receiving the top opening and bottom opening of the soft sieve respectively, a top cap ring fastened to the top opening of hard sieve to hold the top opening of the soft sieve in place, a bottom cap ring fastened to the bottom opening of the hard sieve to hold the bottom opening of the soft sieve in place, and a soft mesh mounted in the bottom cap ring. Further, the mesh size of the soft sieve and the mesh size of the soft mesh are smaller than the mesh size of the hard sieve.
