Solution Overview

Problem

Existing liquid cleaning elements face mechanical instability issues due to the tendency of materials to relax or deform after connection, leading to potential cracks and stress, especially in bent sections, which compromises their shape and functionality.

Innovation Solution

The carrier medium is pre-manufactured in its final shape, allowing it to be connected to the cleaning medium without mechanical stress, thereby maintaining stability and preventing deformation or relaxation, with integrated liquid connectors for efficient liquid handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the carrier medium is shaped after connection with the cleaning medium, then the liquid cleaning element can be formed with integrated components, but the material tends to relax into its original flat state causing mechanical stress and potential cracks

Engineering Contradiction:
Improveintegration of componentsVSAvoidmechanical stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The carrier medium is pre-shaped into the final three-dimensional geometry of the liquid cleaning element before being connected to the cleaning medium. This preliminary shaping action eliminates the need for post-connection deformation, preventing material relaxation and mechanical stress that would otherwise occur when bending the carrier medium after assembly.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the carrier medium is pre-manufactured in final shape, then mechanical stability is improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvemechanical stabilityVSAvoidmanufacturing process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The liquid cleaning element is divided into two separate components: the carrier medium and the cleaning medium. The carrier medium is manufactured separately in its final three-dimensional shape, while the cleaning medium is applied or attached afterward. This segmentation allows each component to be optimized independently for its specific function and manufacturing requirements.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the carrier medium is bent after connection, then the liquid cleaning element can be adapted to fit specific spaces, but the cleaning medium may slide on the carrier medium to relax into initial position

Engineering Contradiction:
Improveshape adaptationVSAvoidposition stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The carrier medium is pre-formed into the required three-dimensional shape and configuration before the cleaning medium is applied. This ensures that the final assembled element maintains its intended geometry and position without subsequent relaxation or sliding, as no post-assembly bending is required.

Inventive Principle:
Principle #10Preliminary action
