Method and communication system for the coupled operation of an electric scrubbing brush and an electric pump device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric scrubbing brush pumps are inefficient as they operate independently of the brush's needs, leading to unnecessary power consumption and wear, and often activate undesirably due to pressure loss or sensor malfunctions, causing delays and increased energy demand.
Innovation Solution
A method for coupled operation between an electric scrubbing brush and a pump device, where the brush's activation signals control the pump's operation, ensuring the pump only supplies water when needed, matching the brush's requirements in terms of pressure and amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump operates continuously to ensure water supply, then the water pressure and amount are maintained, but unnecessary power consumption increases and pump wear accelerates
Solution Approach 1:
The pump control system uses feedback from the scrubbing brush operation status and pressure sensor readings to dynamically adjust pump operation. The control unit receives signals about brush activation and pressure conditions, then activates or deactivates the pump accordingly, ensuring water supply only when actually needed rather than operating continuously.
Solution Approach 2:
The system enables the pump to automatically respond to its own operational needs through integrated sensors and control logic. The pressure sensor detects pressure loss and triggers pump activation, while the brush operation status automatically controls pump deactivation, creating a self-regulating system that serves its own control requirements without external intervention.
2Reliability
If the pump activates on pressure loss to maintain water supply, then water pressure is maintained, but activation delay occurs due to valve opening requirements
Solution Approach 1:
The system performs preliminary actions by keeping the pressure line valve in a pre-open state during normal operation and using communication signals for pump activation. This eliminates the need for delayed valve opening sequences, allowing the pump to activate immediately when brush operation changes, thus maintaining water pressure without time loss.
Solution Approach 2:
The patent replaces the traditional mechanical pressure-loss-activated pump system with an electronically controlled system using communication interfaces. Instead of relying on mechanical valve opening sequences triggered by pressure sensors, the system uses electronic signals from the brush to directly control pump activation, eliminating mechanical delays.
3Ease of operation
If the pump operates independently without brush coordination, then pump operation is simple, but unnecessary activation occurs due to pressure line leakage or sensor malfunctions
Solution Approach 1:
The pump control system incorporates dual feedback mechanisms: one from the brush operation status via communication interface and another from pressure sensors. The control unit processes both feedback streams and requires consistent signals for pump activation, preventing false activation from sensor malfunctions or pressure line leakage while maintaining simple operation through automated decision logic.
Solution Approach 2:
The control unit serves multiple functions: it receives communication signals from the brush, processes pressure sensor inputs, makes activation decisions, and controls pump operation. This multi-functional approach integrates simplicity with reliability, allowing the single control unit to coordinate all aspects of pump operation based on comprehensive system status information.
4Quantity of substance
If the pump is always activated to ensure water availability, then water supply is guaranteed, but energy demand increases and pump lifespan decreases
Solution Approach 1:
Instead of continuous operation, the pump operates periodically based on actual demand signals from the scrubbing brush. The pump activates when the brush is turned on and deactivates when the brush stops, creating a periodic operation pattern that guarantees water supply availability only when needed while minimizing energy waste during idle periods.
Solution Approach 2:
The system discards the traditional approach of continuous pump operation and recovers energy by activating the pump only during necessary periods. The control system identifies and eliminates energy-wasting continuous operation, replacing it with demand-based periodic activation that maintains water supply availability while recovering lost energy efficiency.
