Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heating and cooling systems are used in dialysis clinics, then thermal comfort can be maintained, but high energy consumption and CO2 emissions result
Solution Approach 1:
The patent recovers thermal energy from dialysis waste water, which would otherwise be discharged as waste heat, and uses it for space heating and hot water supply. This converts a harmful waste stream into a beneficial energy source, reducing the need for conventional heating systems and lowering CO2 emissions while maintaining thermal comfort in patient rooms.
Solution Approach 2:
The system uses the dialysis process itself to generate thermal energy for the building. The waste water from dialysis treatments, which is naturally warmed during the treatment process, serves as a heat source for heating the clinic spaces and providing hot water, making the system self-sufficient rather than relying entirely on external energy sources.
2Object-generated harmful factors
If photovoltaic systems are installed to generate renewable energy, then CO2 emissions are reduced, but roof space and installation complexity increase
Solution Approach 1:
The patent integrates multiple functions into a single system: the heat pump provides both heating and cooling capabilities, the photovoltaic system generates electricity for both general building operations and specifically for powering the heat pump, and the waste water heat recovery system provides both space heating and domestic hot water. This multi-functionality reduces overall system complexity despite the addition of renewable energy components.
Solution Approach 2:
The patent combines several energy systems into an integrated energy management system: photovoltaic panels are installed on the roof to generate electricity, which powers a heat pump that provides heating and cooling, while simultaneously a heat recovery system captures thermal energy from dialysis waste water. These systems work together as a unified approach to achieve energy self-sufficiency and eliminate CO2 emissions.
3Loss of energy
If waste water heat recovery is implemented, then energy efficiency improves, but system complexity and initial investment increase
Solution Approach 1:
The patent installs a heat recovery system that captures thermal energy from dialysis waste water, which would otherwise be discharged to the sewer system. This converts a waste product into a valuable energy resource, pre-heating incoming fresh water and providing space heating, thereby dramatically improving energy efficiency of the dialysis process while the added system complexity is offset by long-term energy savings.
