Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If reverse osmosis process is used to purify water, then water purification quality is improved, but large amount of wastewater is generated that requires manual disposal
Solution Approach 1:
The system automatically recycles wastewater through the mixing member without user intervention. The mixing member mixes purified water with wastewater and delivers it to the water device, enabling the system to handle wastewater disposal autonomously and improving operational convenience.
2Device complexity
If wastewater is discharged directly without recycling, then system complexity is reduced, but water resource efficiency deteriorates
Solution Approach 1:
Instead of discarding wastewater, the system recovers it by channeling through the mixing member where it is mixed with purified water. This recovered mixed water is then delivered to the water device, transforming waste into useful resource and improving water efficiency.
Solution Approach 2:
The mixing member serves multiple functions: it mixes purified water with wastewater, acts as a flow control device, and delivers mixed water to the water device. This multi-functionality enables wastewater recycling without proportionally increasing system complexity.
3Loss of substance
If mixing member with tapered holes is used to recycle wastewater, then water resource efficiency is improved, but device complexity increases
Solution Approach 1:
The mixing member features tapered holes with varying diameters at different locations to create different flow resistance characteristics. This local variation in hole geometry optimizes mixing efficiency and flow control while keeping the overall structure relatively simple.
4Reliability
If non-return members are installed in connecting members, then water flow control reliability is improved, but device complexity increases
Solution Approach 1:
The non-return function is extracted as a separate movable component within the connecting member, allowing it to be independently controlled by water pressure. This extraction enables reliable one-way flow control while maintaining relatively simple overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively recycles wastewater by pumping it back into the system for reuse, achieving water savings and sterilization without compromising water quality, addressing the inefficiencies of manual disposal and wastewater management in conventional systems.
Implementation Method 1
Reverse osmosis (RO) system is a water purification technology which can remove ions, molecules and particles from drinking water
Implementation Method 2
A mixing chamber formed inside the mixing member is communicated with the water inlet end through a tapered water inlet hole which has a gradually-larger diameter from the mixing chamber to the water inlet end while the mixing chamber is communicated with the water outlet end through a tapered water outlet hole which has a gradually-larger diameter from the mixing chamber to the water outlet end
Implementation Method 3
The mixing member is connected to the wastewater inlet tube through a first connecting member which comprises a first non-return member installed therein
Implementation Method 4
the mixing member is also connected to an ozonizer, and when the negative pressure is generated in the mixing chamber, an appropriate amount of ozone is configured to flow into the mixing chamber to mix with water

AI summary
A reverse osmosis system may include a water supply, a filter, and a mixing member. The water supply is connected to a first water tube and a second water tube. The first water tube is connected to the filter, and the filter is connected to a drain pipe which is connected to a wastewater tank. The wastewater generated from the filter under reverse osmosis process can be discharged into the wastewater tank. The mixing member has a water inlet end, a water outlet end, and a wastewater inlet tube, which are communicated with each other, and the water inlet end of the mixing member is connected to the second water tube. When water flows through the mixing member, the negative pressure is generated to pump wastewater in the wastewater tank through the wastewater inlet tube into the mixing member, thereby achieving the effect of water saving.
