Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for flushing central heating systems, such as power flushing, require a separate and expensive pump, result in high water usage, and dilute cleansing chemicals, leading to inefficiencies and environmental concerns.
Innovation Solution
A method involving a magnetic filter with two chambers, using the system's pump to circulate water, applying vibration to radiators to dislodge sediment, and adding a cleaning product to improve effectiveness, which reduces water usage and eliminates the need for a separate power flushing machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If power flushing is used to remove sludge and deposits, then cleaning effectiveness is improved, but water consumption increases significantly
Solution Approach 1:
The patent applies mechanical vibration directly to radiators and heat exchangers to dislodge sludge and deposits. The vibrator device generates vibrations that travel through the system components, loosening accumulated contaminants without requiring high-volume water flow, thereby achieving effective cleaning with minimal water consumption.
Solution Approach 2:
The patent introduces a magnetic filter as an intermediary device that captures and removes sludge and deposits from the circulating water. This filter allows the system to achieve cleaning effectiveness by trapping contaminants in the magnetic field rather than relying on high-volume water flushing, significantly reducing water consumption.
2Power
If a separate power flushing pump is used, then flushing capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing system pump multi-functional by having it serve both its normal circulation function and the flushing function. The pump circulates water during normal operation and also drives the flushing process when the vibrator is activated, eliminating the need for a separate power flushing pump and reducing device complexity.
Solution Approach 2:
The system uses its own existing pump to perform the flushing operation, making the system self-sufficient. The pump that already exists in the heating system is utilized for both circulation and flushing, eliminating the need for external specialized equipment and simplifying the overall system.
3Manufacturing precision
If high flow rate flushing is used, then contaminant removal is improved, but cleansing chemical effectiveness is reduced due to dilution
Solution Approach 1:
The vibrator device mechanically dislodges contaminants from surfaces, allowing cleansing chemicals to work more effectively on loosened debris rather than trying to dissolve heavy sludge deposits. This mechanical action reduces the amount of water needed for flushing, thereby maintaining higher concentrations of cleansing chemicals in the circulating water.
Solution Approach 2:
The magnetic filter acts as an intermediary that concentrates and removes contaminants from the water stream. This allows the system to use lower volumes of water with higher concentrations of cleansing chemicals, as the filter captures particles that would otherwise require large volumes of water to flush out.
