Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses face challenges in controlling the ratio of detergent to water in cleaning solutions, leading to inefficiencies and increased costs due to complex structures and the need for multiple motors to pump different liquids.
Innovation Solution
A dual-head pump system with a single drive motor integrated with two pump bodies on opposite sides, allowing simultaneous pumping of clean water and detergent, simplifying the structure and reducing costs while maintaining a fixed mixing ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate pumps and motors are used for clean water and detergent, then the cleaning solution ratio can be controlled, but the device structure becomes complex and costs increase
Solution Approach 1:
The patent combines two separate pump bodies into a single integrated dual-head pump unit with a shared motor and housing. The first pump body handles clean water while the second pump body handles detergent, both driven by a common motor through synchronized drive mechanisms. This merging reduces the number of separate components, simplifies the overall structure, and lowers manufacturing costs while maintaining precise control over the cleaning solution mixing ratio through coordinated pumping action.
2Productivity
If multiple motors are used to pump different liquids, then liquid pumping capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent implements a universal motor design that performs multiple functions by driving both the first pump body for clean water and the second pump body for detergent simultaneously. The single motor is coupled to both pump bodies through drive mechanisms that enable independent control of each pump while sharing the same power source. This multi-functional approach maintains full liquid pumping capability for both substances while eliminating the need for separate motors, thereby reducing device complexity and cost.
