Soap Dispenser Makeup Air System for Consistent Liquid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soap dispenser systems lack efficient mechanisms for dispensing soap and maintaining air pressure to ensure consistent liquid dispensing and prevent liquid from remaining in the container.
Innovation Solution
A dispenser system with an air pump that provides makeup air through an inlet valve, connected to a container via an interface assembly with elastomeric valves, and a mechanism using spring arms and latches to secure the container, ensuring consistent dispensing and preventing liquid overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air pressure is used to dispense liquid soap, then dispensing consistency is improved, but liquid may remain in the container causing incomplete dispensing
Solution Approach 1:
The patent applies pneumatic principles by introducing an air pump that delivers makeup air to the container interior through an inlet valve. This pressurized air displaces the liquid soap toward the outlet, ensuring complete dispensing. The system uses gas pressure to move liquid, directly applying pneumatic-hydraulic interaction to resolve the issue of liquid remaining in the container.
2Measurement precision
If elastomeric valves are used to control air and liquid flow, then flow control precision is improved, but device complexity increases
Solution Approach 1:
The elastomeric inlet and outlet valves are designed to automatically respond to pressure changes within the system. When air pressure increases, the elastomeric material naturally deforms to open or close flow paths without requiring external actuation mechanisms. This self-regulating behavior provides precise flow control while minimizing additional mechanical complexity.
3Reliability
If spring arms and latches are used to secure the container, then container retention reliability is improved, but mechanism complexity increases
Solution Approach 1:
The spring arm and latch mechanism operates through periodic engagement and disengagement cycles. The spring arms provide continuous retaining force during normal operation, then automatically release when a key is inserted to rotate the dispensing mechanism. This periodic action pattern ensures reliable container retention during dispensing while allowing easy release when needed, balancing reliability with operational simplicity.
