Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foam soap dispensers are prone to damage and malfunction due to their disposable and mechanically driven design, which limits their functionality and reliability.
Innovation Solution
A battery-powered foam soap dispenser is designed with a motor, stirring unit, and pump system that uses a series of stirring gears to generate foam, where the motor drives the stirring unit and pump simultaneously, allowing the elastic sleeve body to extract and deliver soap liquid to the stirring unit, resulting in the creation of foam output through an output tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical structure with vertical movement pump is used, then the dispenser can deliver soap liquid, but it is prone to damage and malfunction
Solution Approach 1:
The patent replaces the conventional mechanical vertical movement pump with an elastic sleeve pump that uses elastic deformation to achieve liquid delivery. The elastic sleeve body expands and contracts to draw soap liquid from the container and deliver it to the stirring unit, eliminating complex mechanical linkages and reducing malfunction risks.
Solution Approach 2:
The patent changes the operational parameter from mechanical vertical movement to elastic expansion and contraction. The elastic sleeve body changes its volume and shape through elastic deformation, enabling the pump to deliver soap liquid without complex mechanical structures. This parameter change improves reliability while simplifying the device.
2Ease of manufacture
If conventional disposable pumps are used, then the dispenser is simple to manufacture, but it has easy damage and malfunction
Solution Approach 1:
The patent employs an elastic sleeve body as the pump component, which is a flexible element that expands and contracts to deliver soap liquid. This flexible shell design simplifies manufacturing compared to traditional mechanical pumps while improving reliability by eliminating complex mechanical parts that are prone to damage and malfunction.
3Manufacturing precision
If a motor-driven stirring gear system is used, then meticulous foam soap liquid is generated, but the device complexity increases
Solution Approach 1:
The patent merges the motor, stirring unit, and pump into an integrated system where the motor drives both components simultaneously. The stirring gears are positioned within the stirring unit housing, and the motor's transmission shaft directly connects to the stirring mechanism. This merging reduces overall device complexity while maintaining the ability to generate meticulous foam soap liquid.

Function Achieved in This Case
The battery-powered dispenser enhances the reliability and functionality of foam soap delivery by generating consistent and meticulous foam output, reducing the risk of damage and malfunction compared to conventional designs.
Implementation Method 1
an elastic sleeve body of the pump is operated by the motor to contract and expand, allowing the second tube to extract the soap liquid from the container to the pump
Implementation Method 2
the rotation of the stirring gears allows the soap liquid to become foam

AI summary
A foam soap dispenser includes a motor, stirring unit, pump and container, where the motor is combined with and linked to the stirring unit and pump; an output tube is configured on the front end of the stirring unit; the pump has an elastic sleeve body, first and second tubes, where the second tube is in communication with the container inside which soap liquid is filled. The motor drives the stirring unit and pump to operate simultaneously after the motor is started, an elastic sleeve body of the pump is operated by the motor to contract and expand, allowing the second tube to extract the soap liquid from the container to the pump, and the soap liquid is then delivered to the stirring unit through the first tube. Finally, the rotation of the stirring gears allows the soap liquid to become foam, which is output through the output tube.
