Foam supplying device for bathroom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foam supplying devices for bathrooms require complex installation processes due to the need for separate installation of the device body, compressor, and compressed air supply units, as well as external hoses and wiring.
Innovation Solution
A foam supplying device with a built-in compressor and battery, integrated into a single housing unit that includes a flow channel, water inflow and foam outflow ports, and a three-way valve for switching between water and foam output, eliminating the need for external compressed air and power supply arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the compressor and compressed gas supply unit are disposed outside the housing, then the device can be manufactured with separate components, but the installation work becomes complicated requiring hose arrangement and multiple installation steps
Solution Approach 1:
The patent integrates the compressor and battery into the housing to form a single integrated unit. The compressor is disposed in the housing with its inlet communicating with the atmosphere and outlet communicating with the flow channel, while the battery is mounted in the housing to supply power to the compressor. This merging eliminates the need for external hoses and separate installation of compressed gas supply units, significantly simplifying the installation process while maintaining manufacturing feasibility.
2Ease of manufacture
If external hoses and wiring are used to connect the compressed gas supply unit, then the components can be separated for easier manufacturing, but the installation complexity increases
Solution Approach 1:
The patent combines the compressor, battery, and housing into a single integrated assembly where the compressor is disposed in the housing and the battery is mounted in the housing. The compressor inlet communicates with the atmosphere and the outlet communicates with the flow channel, eliminating the need for external hoses. The battery supplies power directly to the compressor within the housing, eliminating external wiring requirements for power supply.
3Ease of operation
If the compressor is built in the housing, then the installation process is simplified, but the device structure becomes more integrated and complex
Solution Approach 1:
While integrating components, the patent maintains functional segmentation: the housing provides structural support and containment, the compressor is disposed in the housing as a distinct functional unit with separate inlet and outlet communications, and the battery is mounted in the housing as a separate power supply unit. This segmentation allows for modular assembly and maintenance while achieving the simplified installation benefit of integration.
