Washing machine control panel base with function of automatically adding detergent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fully automatic washing machines have inconvenient detergent dispensing systems, where detergents need to be manually added, affecting aesthetics, user experience, and the accuracy of detergent dispensing, which is not suitable for modern automation and environmental protection standards.
Innovation Solution
A control panel base with integrated chambers for solid detergents, containers for liquid detergents, and an automatic detergent dispensing apparatus using a Venturi tube for quantitative delivery, with detergent dispensing ports on the upper surface, facilitating convenient and accurate detergent addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the detergent box is disposed inside the control panel base, then the structure is compact, but the aesthetics are affected and support strength is reduced
Solution Approach 1:
The detergent box is extracted from the control panel base and disposed separately at the rear side, below the control panel base. This separation resolves the contradiction by allowing the control panel base to maintain its structural integrity and aesthetic appearance while still providing space for the detergent box in the overall washing machine structure.
2Volume of moving object
If the detergent box is disposed inside the control panel base, then the structure is compact, but the support strength is reduced
Solution Approach 1:
The detergent box is extracted from the control panel base and disposed separately at the rear side. This separation ensures that the control panel base maintains its full support strength for the display screen and operation buttons, while the detergent box is supported by the rear structure of the washing machine.
3Device complexity
If the detergent box is disposed at back of the control panel base, then the structure is simplified, but the user convenience is reduced
Solution Approach 1:
The detergent box is positioned in a different spatial dimension - at the rear side below the control panel base rather than inside it. This dimensional repositioning allows the box to be accessible to users from the rear or side, maintaining simplicity in the control panel base structure while improving user accessibility.
4Device complexity
If manual detergent dispensing is used, then the device complexity is reduced, but the dispensing accuracy is poor
Solution Approach 1:
The washing machine system automatically dispenses detergent from the detergent box based on pre-programmed dosing requirements, eliminating the need for manual user intervention. This self-service mechanism ensures accurate dispensing amounts according to different washing modes and fabric types, resolving the contradiction between simplicity and precision.
5Ease of operation
If detergent dispensing ports are added on the upper surface, then the user convenience is improved, but the structure complexity increases
Solution Approach 1:
The upper surface of the control panel base is designed with detergent dispensing ports that serve multiple functions: allowing users to add detergent, enabling automatic dispensing, and maintaining aesthetic appearance. This multi-functional design improves user convenience while minimizing additional structural complexity.
