Solution Overview

Problem

Existing clothing treatment devices face issues with the reliability and stability of split-type detergent dispensing assemblies, leading to loose connections and potential damage during use.

Innovation Solution

A clothing treatment agent dispensing assembly with a docking mechanism that includes slidingly connected dispensing and storage containers, utilizing positioning pins and pin holes for secure engagement, and a sealing ring to prevent separation and leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a split-type dispensing box and storage box are used, then the overall size of the dispensing assembly is reduced, but the connection reliability between the boxes deteriorates

Engineering Contradiction:
Improveoverall size of dispensing assemblyVSAvoidconnection reliability between dispensing box and storage box
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The dispensing assembly is divided into separate dispensing box and storage box components that can be independently manufactured and assembled, reducing overall assembly size while maintaining functionality through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dispensing box is positioned to overlap with the storage box in the vertical direction, with the front end of the dispensing box extending beyond the front end of the storage box. This nested arrangement reduces the horizontal footprint of the assembly while maintaining reliable connection through the docking mechanism between the two boxes

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a drawer-type integrally formed dispensing box and storage box are used, then the connection reliability is improved, but the opening size on the panel increases

Engineering Contradiction:
Improveconnection reliability of dispensing assemblyVSAvoidopening size on panel
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The dispensing assembly is segmented into separate dispensing box and storage box components, each with its own opening on the panel. This allows for smaller individual openings compared to a single large opening required for an integrally formed drawer-type assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The nested arrangement where the dispensing box overlaps with the storage box vertically allows both components to access the panel through smaller, staggered openings rather than requiring one large opening, thus reducing the total panel area occupied

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A clothes treating agent dispensing assembly for a clothes treatment device and a clothes treatment device including a body; the clothes treating agent dispensing assembly including a dispensing container, a storage container and a docking mechanism. The dispensing container and the storage container are both in sliding connection with the body; the docking mechanism can engage the dispensing container and the storage container with each other and cause the dispensing container and the storage container to stably slide relative to the body as a whole. The docking mechanism can engage the dispensing container and the storage container with each other and avoid relative movement of the dispensing container and the storage container, so the relative stability of the dispensing container and the storage container is maintained when a drawer is moved, and the dispensing container and the storage container both can slide stably relative to the body.
