Solution Overview

Problem

Existing carbon block liquid treatment devices face issues with non-uniform liquid flow distribution and the need for simultaneous replacement of the post-filter and carbon block, leading to inefficient use of the post-filter and increased frequency of carbon block replacement.

Innovation Solution

A detachable liquid treatment device with an upper and lower treatment unit, featuring a housing with multiple inlets and outlets, and a sealing mechanism that allows independent replacement from the carbon block, ensuring uniform liquid flow distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the post-filter and carbon block are integrated together, then the sealing and structural stability are improved, but the replacement flexibility deteriorates as they must be replaced simultaneously

Engineering Contradiction:
Improvestructural stabilityVSAvoidreplacement flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The liquid treatment device is divided into separate components: the carbon block and the liquid treatment device with post-filter are detachably connected. This allows the post-filter to be replaced independently from the carbon block, resolving the contradiction by enabling flexible replacement while maintaining structural integrity during operation through the detachable connection mechanism.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the post-filter is made detachable from the carbon block, then the replacement flexibility is improved, but the sealing reliability deteriorates

Engineering Contradiction:
Improvereplacement flexibilityVSAvoidsealing reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A detachable connection mechanism serves as an intermediary between the carbon block and the liquid treatment device. This mechanism includes sealing components that ensure reliable sealing when connected, while allowing easy detachment for replacement. The intermediary structure resolves the contradiction by providing both secure connection for sealing and ease of separation for replacement.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If liquid enters only from the bottom of the carbon block, then the device complexity is reduced, but the liquid flow distribution deteriorates causing non-uniform treatment

Engineering Contradiction:
Improvedevice complexityVSAvoidliquid flow distribution uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The liquid inlet is extended from a single bottom inlet to multiple inlets distributed across different surfaces of the carbon block (side surface and top surface). This dimensional expansion of the inlet configuration enables uniform liquid flow distribution throughout the carbon block without significantly increasing device complexity, as the additional inlets are simply openings in existing surfaces.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
