Solution Overview

Problem

The conventional beverage infuser's filter positioning structure faces issues with easy engagement and disengagement, leading to potential noise and wear due to loose or tight connections, affecting the filter's separation from the cover and body.

Innovation Solution

A filter positioning structure featuring a casing member with a ring-shaped upper engaging part, a column-shaped connecting part, and a lower engaging part, where the upper engaging part has protruding parts for secure positioning and easy removal, and a C-shaped hole for smooth passage of the sucking pipe.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the engagement between the blocking part and the hook part is too tight, then the filter is firmly positioned in the cavity, but the blocking part is easy to be locked by the hook part and difficult to be taken off from the cavity

Engineering Contradiction:
Improvefirm positioning of filter in cavityVSAvoidease of separation of filter from cover
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The engagement structure transitions from a static tight-fit design to a dynamic system where the elastic blocking part can deform during assembly and disassembly. The elastic material allows the blocking part to be compressed during insertion for firm engagement, then naturally rebound to facilitate easy removal when force is applied, resolving the contradiction between firm positioning and ease of separation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the physical parameter of the blocking part from rigid to elastic, allowing it to change shape under different conditions. During assembly, the elastic blocking part deforms to pass through the hook part, creating firm engagement. During disassembly, the elastic property allows it to deform again to release from the hook part, solving both the firm positioning and easy removal requirements.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the engagement between the blocking part and the hook part is too loose, then the filter can be easily removed from the cavity, but the filter is easy to touch the inside wall of the body during separation and the blocking part may escape from the cavity

Engineering Contradiction:
Improveease of removal of filter from cavityVSAvoidreliable restriction of blocking part by hook part
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The blocking part is designed with a curved or rounded shape that complements the hook part's geometry. This curved design allows the blocking part to naturally follow the contour of the hook part during engagement, ensuring reliable restriction while maintaining ease of removal. The curvature enables smooth motion during assembly and disassembly without creating sharp edges that would cause jamming or escaping.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of operation

If the filter is loosely engaged in the body, then the filter can be easily separated, but the filter may collide the inside wall of the body during shaking to cause noise and wearing

Engineering Contradiction:
Improveease of separation of filterVSAvoidnoise and wearing from filter collision with body wall
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The engagement system is segmented into distinct functional zones: the elastic blocking part for secure engagement, the hook part for positioning, and the spaced relationship between the filter and body wall. This segmentation allows the filter to be firmly held during normal operation (preventing collision and noise) while enabling easy separation when needed, as the blocking part can be independently manipulated to release from the hook part.

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure illustrates a filter positioning structure for a beverage infuser. In the filter positioning structure, a casing member includes upper and lower engaging parts respectively connected with top and bottom ends of a connecting part. A filter can be combined with the lower engaging part. The upper engaging part is ring-shaped and has protruding parts on an outer periphery thereof. Therefore, the filter positioning structure can be positioned in the beverage infuser by blocking between the protruding parts and a stop part of a body of the beverage infuser.
