Solution Overview

Problem

Existing washing machines lack an efficient and intuitive method for automatically or manually supplying detergents, with existing solutions not allowing for easy removal or direct discharge of detergent mixed water to the washing tub.

Innovation Solution

A washing machine design featuring a removable detergent dispenser with a built-in pump system, where the detergent is mixed with water and directly discharged into the washing tub, allowing for automatic or manual operation and easy removal of the dispenser for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the detergent dispenser is made removable for easy maintenance, then the ease of repair is improved, but the device complexity increases due to additional coupling mechanisms

Engineering Contradiction:
Improveease of removalVSAvoiddevice complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The detergent dispenser is designed as a separable component that can be removed from the washing machine body. The dispenser includes a container, pump, and coupling mechanism that allow it to be detached and reattached. This segmentation enables easy maintenance and cleaning of the dispenser without disassembling the entire washing machine.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pump is integrated inside the detergent dispenser container, creating a nested structure where the pump housing is formed by the container walls. This nesting reduces the overall number of separate components and simplifies the coupling mechanism between the dispenser and the washing machine body.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the detergent dispenser is positioned in the upper portion of the washing machine, then the ease of operation is improved for user access, but the length of the detergent supply path increases

Engineering Contradiction:
Improveease of accessVSAvoidsupply path length
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The detergent is pre-mixed with water in the dispenser container before being supplied to the washing tub. This preliminary mixing action occurs at the upper portion location, allowing the detergent to be prepared in advance and then discharged directly, reducing the effective supply path length for the actual detergent delivery.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pump uses hydraulic principles to move the detergent solution from the upper dispenser location to the washing tub. The pump creates pressure to propel the detergent through the supply path, effectively compensating for the increased distance by using fluid pressure rather than gravity alone.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Extent of automation

If automatic detergent supply is implemented using a pump, then the extent of automation is improved, but the device complexity increases due to additional mechanical components

Engineering Contradiction:
Improveautomation levelVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The pump is integrated within the detergent dispenser assembly, merging the pumping function with the storage function. This combination reduces the number of separate mechanical components in the washing machine, as the pump becomes part of the removable dispenser unit rather than a fixed component in the main body.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pump serves multiple functions: it stores detergent, mixes detergent with water, and supplies the mixed solution to the washing tub. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity while maintaining automation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If the detergent dispenser allows direct discharge to the washing tub, then the productivity is improved by reducing transfer time, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvedetergent supply efficiencyVSAvoidalignment precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The coupling mechanism between the dispenser and the washing machine body is designed to be dynamically adjustable, allowing for automatic alignment during the coupling process. This dynamic adjustment compensates for manufacturing tolerances and ensures proper alignment of the discharge path with the washing tub opening.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The dispenser is designed with self-aligning features that automatically position the discharge opening correctly when coupled to the washing machine body. The coupling mechanism includes guide elements and positioning features that ensure accurate alignment without requiring high-precision manual assembly.

Inventive Principle:
Principle #25Self-service
