Detergent dispenser for washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with detergent dispensers often require users to exert considerable effort when adding detergents, risk damaging the dispenser due to the weight of the detergent container, and restrict the front design of the machine, making it inconvenient and aesthetically limiting.
Innovation Solution
A washing machine design featuring a detergent dispenser located above the tub with a dispenser cover that opens and closes, allowing easy access and reducing interference with the air supply device, while separating detergent and subsidiary detergent input areas for improved user convenience and design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detergent dispenser is positioned on the front surface of the washing machine, then users can easily access the dispenser to add detergents, but this restricts the front design of the washing machine
Solution Approach 1:
The detergent dispenser is moved from the front surface to the upper surface of the washing machine, changing the spatial dimension of access. This allows users to access the dispenser from above rather than from the front, thereby maintaining ease of operation while freeing up the front surface for design purposes.
2Ease of operation
If users hold the detergent container while adding detergents to the dispenser, then detergent can be transferred, but users may exert considerable effort and be inconvenienced or hurt
Solution Approach 1:
The dispenser opening is positioned at an elevated location on the upper surface, creating an equipotential relationship between the detergent container and dispenser. This allows detergent to be poured or transferred without the user needing to lift or hold the container at an awkward height, reducing physical strain and improving ergonomics.
3Ease of operation
If the detergent container is placed on the detergent dispenser during pouring, then detergent transfer is simplified, but the detergent dispenser may be damaged by the load of the container
Solution Approach 1:
The detergent container is extracted or removed from the dispenser after the pouring process is complete. The design allows for temporary placement during pouring but requires the container to be taken out afterward, preventing continuous loading that would damage the dispenser structure while still enabling easy detergent transfer.
4Ease of operation
If the detergent dispenser is positioned on the front surface, then detergent access is convenient, but it interferes with the air supply device and limits design options
Solution Approach 1:
The detergent dispenser is relocated from the front surface to the upper surface of the washing machine, utilizing a different spatial dimension. This relocation eliminates interference with the air supply device on the front surface while maintaining convenient access for users, thereby reducing overall system complexity and design constraints.
