Method and communication system for the coupled operation of an electric washing brush and an electric pump device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric washing brush pumps are inefficient as they provide water pressure unnecessarily and wear out quickly due to indirect water supply mechanisms, which lead to energy wastage and premature wear, and lack the ability to adapt to different operating modes of the washing brush.
Innovation Solution
A method where an electric washing brush and pump device are operated by separate battery packs, with the pump automatically activating or changing operation based on the brush's activation or operating mode, ensuring water is supplied only when needed, with adjustable pressure and quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is always activated to provide water pressure, then water supply is ensured, but energy consumption increases and pump wear increases
Solution Approach 1:
The pump control system uses feedback from the washing brush operation status to automatically activate or deactivate the pump. When the washing brush is activated, the pump receives an activation signal and starts providing water; when the brush is deactivated, the pump stops. This feedback mechanism ensures water supply reliability only when needed, eliminating continuous energy consumption and unnecessary pump wear.
Solution Approach 2:
The system establishes a predetermined operational relationship between the washing brush and pump, where the pump is pre-configured to activate automatically upon brush activation. This preliminary setup eliminates the need for separate pump activation actions and ensures immediate water supply when the brush is used, while preventing unnecessary operation when the brush is not in use.
2Loss of energy
If the pump activates only after pressure loss is detected, then energy is saved, but water supply is delayed
Solution Approach 1:
Instead of waiting for pressure loss to occur before activating the pump, the system pre-establishes the operational link between brush activation and pump activation. The pump activates immediately when the brush is turned on, before any water extraction or pressure loss occurs. This preliminary action eliminates the time delay associated with pressure loss detection while still avoiding unnecessary pump operation when the brush is not in use.
3Device complexity
If the pump operates independently without adapting to brush operation modes, then pump control is simple, but water pressure and quantity cannot be optimized for different cleaning needs
Solution Approach 1:
The pump control system receives feedback signals from the washing brush that indicate different operating modes or activation states. Based on this feedback, the pump automatically adjusts its operation to provide appropriate water pressure and quantity for each mode. This feedback-based adaptation enables the pump to respond to different cleaning needs without requiring complex manual controls or multiple pump units.
