Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RO water purifiers face challenges in maintaining a constant and high flow rate for dispensing hot or cold water, especially when high temperatures are required, which can lead to inefficient use of purified water.
Innovation Solution
The RO water purifier incorporates a compartment for storage of pre-heated or pre-cooled purified water, along with a booster pump and a device for further heating or cooling, allowing for consistent high-flow dispensing of water at desired temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If in-line heating mechanism is used to dispense hot water, then water is heated on-demand, but flow rate becomes limited when high temperatures are required
Solution Approach 1:
The patent applies preliminary action by pre-heating purified water in a dedicated storage tank before dispensing. The heating element continuously or periodically heats water in the storage tank, so that hot water is already prepared and available when needed, eliminating the need for on-demand heating during dispensing and thus maintaining high flow rates.
2Temperature
If high power heating element is used to heat water to very high temperatures, then desired temperature is achieved, but flow rate becomes limiting
Solution Approach 1:
The system pre-heats water in a storage tank before dispensing, so that when hot water is requested, pre-heated water is immediately available for dispensing without limiting the flow rate. This separates the heating function from the dispensing function in time.
Solution Approach 2:
The heating function is segmented from the dispensing function. The heating element operates independently in the storage tank, while the dispensing system operates independently at the outlet. This segmentation allows both functions to operate at optimal capacities without constraining each other.
3Use of energy by moving object
If purified water is heated on-demand without storage, then energy efficiency is improved, but flow rate cannot be maintained constant and high
Solution Approach 1:
The system performs preliminary heating action by maintaining a supply of pre-heated water in the storage tank. This allows the system to switch between using pre-heated water (when available) and ambient water (when tank is empty), ensuring consistent high flow rate while managing energy consumption efficiently.
