Kitchen Faucet Wand Soap Compartment With Momentary Diverter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen faucets lack an efficient and eco-friendly way to dispense soap without the need for single-use plastic containers, while being retrofittable and minimally complex.
Innovation Solution
A faucet sprayhead with a soap compartment and a momentary diverter valve that allows selective communication between water and soap, enabling the use of solid soap and reducing plastic waste by integrating it into the faucet design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional soap dispenser with plastic bottles is used, then soap can be dispensed, but plastic waste and carbon emissions increase
Solution Approach 1:
The patent combines the soap storage compartment and water delivery system into a single integrated sprayhead unit. The soap compartment (70) is merged with the waterway (40) and outer shell (42), allowing solid soap to be directly combined with water from the faucet to create soapy water, eliminating the need for separate plastic soap bottles and their associated waste.
Solution Approach 2:
The patent replaces expensive and wasteful single-use plastic liquid soap containers with a reusable sprayhead that accepts solid soap tablets or bars. The solid soap itself becomes the consumable element rather than the plastic container, significantly reducing plastic waste while maintaining the dispensing function.
2Object-affected harmful factors
If a soap dispenser is integrated into the faucet, then plastic waste is reduced, but the device complexity increases
Solution Approach 1:
The sprayhead is designed to perform multiple functions: it can dispense clean water through the first outlet (46) when the diverter valve is in the first position, and it can dispense soapy water through the second outlet (48) when the diverter valve is in the second position. This multi-functionality is achieved within a single integrated unit that attaches to the existing faucet, avoiding the need for separate soap dispensing equipment.
Solution Approach 2:
The patent incorporates a momentary diverter valve (82) that dynamically switches the water flow path between two modes: normal water flow mode (through the first outlet) and soap mixing mode (through the second outlet to the soap compartment). This dynamic switching mechanism allows the system to adapt its function based on user needs without requiring complex permanent modifications to the faucet infrastructure.
3Adaptability or versatility
If a diverter valve is added to enable soap dispensing, then soap functionality is achieved, but the ease of operation decreases
Solution Approach 1:
The momentary diverter valve is designed to be activated temporarily or periodically rather than requiring permanent switching. The user simply presses the diverter button momentarily to activate soap dispensing mode, and the system automatically returns to normal water flow mode when the button is released. This periodic activation approach simplifies operation compared to systems requiring permanent mode switching or complex control mechanisms.
