Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-stage filtration and evaporation systems are used, then wastewater treatment effectiveness is improved, but power consumption and system complexity increase
Solution Approach 1:
The invention extracts and eliminates the complex multi-stage filtration system (primary, secondary, tertiary treatment) and replaces it with a single evaporation-based treatment approach. This removes unnecessary system complexity while maintaining treatment effectiveness through direct solar heating and evaporation of effluent liquid.
Solution Approach 2:
The system uses solar energy for heating and natural convection currents for airflow, eliminating the need for external power sources. The design enables self-powered operation where the sun provides both thermal energy for evaporation and drives air circulation through temperature differential-induced convection.
2Reliability
If conventional filtration systems with multiple treatment stages are implemented, then treatment completeness is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The invention removes the complex multi-stage filtration infrastructure and replaces it with a simple evaporation pan system. This extraction of unnecessary components dramatically reduces device complexity while achieving treatment through phase change and residue separation.
Solution Approach 2:
The system changes the fundamental treatment parameter from filtration (physical separation through membranes) to evaporation (phase change from liquid to vapor). This parameter change simplifies the system structure while maintaining treatment effectiveness through solar thermal energy conversion.
3Ease of repair
If manual cleaning procedures are used for treatment chambers, then cleaning thoroughness can be maintained, but operational time and labor requirements increase
Solution Approach 1:
The evaporation system enables self-cleaning through the natural evaporation process. As effluent liquid evaporates, residues are left behind in controlled amounts, and the system design allows automatic or easily performed cleaning without requiring complex manual intervention or significant operational time.
