Solution Overview

Problem

Existing weight devices for washing machines interfere with fluid drainage due to their design, either requiring separation or reduced thickness, compromising stability and durability.

Innovation Solution

A weight device with an integrated fluid channel within the weight body, allowing for continuous weight and drainage functionality without separation, using a fluid tube and positioning ribs for stability and sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a weight device is provided surrounding the circular access opening to stabilize the washing drum, then the stability of the washing machine is improved, but the fluid drainage path is blocked

Engineering Contradiction:
Improvestability of washing machineVSAvoidfluid drainage
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The fluid channel is nested within the weight body, allowing the drainage tube to be positioned inside the weight device rather than outside. This nesting approach enables both the weight function and fluid drainage function to coexist in the same spatial region without interfering with each other.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The fluid channel extends in the radial direction through the weight body, utilizing the thickness dimension of the weight device to create a drainage path. This dimensional approach allows fluid drainage without compromising the circumferential stability provided by the weight device.

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

2Ease of operation

If the weight device is separated into several parts to provide space for the guiding tube, then the fluid drainage is enabled, but the weight and stability are reduced

Engineering Contradiction:
Improvefluid drainageVSAvoidstability of washing machine
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The weight device and fluid channel are merged into a single integrated component. The weight body itself contains the fluid channel, eliminating the need for separate parts and maintaining the full weight and stability of the unified weight device while enabling fluid drainage.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the weight device is made with reduced thickness to create a groove for the fluid tube, then the fluid drainage is enabled, but the weight and stability are reduced

Engineering Contradiction:
Improvefluid drainageVSAvoidweight of weight device
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The fluid channel is nested within the full-thickness weight body, utilizing the existing thickness rather than reducing it. This allows the weight device to maintain its full weight and stability while still providing a pathway for fluid drainage through the integrated channel.

Inventive Principle:
Principle #7Nested doll (Nesting)
