Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers are often impractical in remote or disaster areas due to power requirements, use of chemicals, and non-portability, particularly because they rely on filters that are expensive and require frequent replacement, and may introduce toxic chemicals into the water.
Innovation Solution
A solar-powered water purifier that uses a main reservoir with a central collection cup and an inverted conical-shaped lid to capture and direct evaporated water condensation into the cup, eliminating the need for electricity, chemicals, and filters, and is constructed from non-contaminating materials like glass and metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water purifiers use filters, pumps, and UV lamps, then water purification effectiveness is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The invention extracts and eliminates the complex components (filters, pumps, UV lamps, chemicals) from the water purification system, retaining only the essential solar-powered distillation mechanism. This simplifies the device while maintaining purification effectiveness through physical phase separation.
Solution Approach 2:
The invention changes the operating parameters from requiring electricity and chemicals to using solar thermal energy. The system operates passively using natural solar heating and condensation processes, eliminating the need for active mechanical or chemical components.
2Reliability
If conventional water purifiers require electricity for pumps and UV lamps, then water purification effectiveness is improved, but adaptability to remote areas without power supply deteriorates
Solution Approach 1:
The invention replaces the mechanical electrical system (pumps, UV lamps requiring electricity) with a passive solar thermal system. Solar energy directly heats the water for distillation, and gravity provides the driving force for water movement, eliminating all electrical components.
Solution Approach 2:
The system uses free solar energy and gravity to perform all purification functions automatically. The solar collector heats water, steam rises and condenses on the cooler lid surfaces, and condensed water drips into the collection container without any external power or control inputs.
3Reliability
If water purifiers use chemicals for purification, then water purification effectiveness is improved, but harmful factors in the output water increase
Solution Approach 1:
The invention uses phase transitions (liquid to vapor to liquid) as the core purification mechanism. Water evaporates leaving contaminants behind, then condenses as pure distilled water on the cooler lid surfaces. This physical separation eliminates chemical contamination while achieving complete purification.
4Reliability
If water purifiers use filters with small pores, then water purification effectiveness is improved, but manufacturing cost and maintenance frequency increase
Solution Approach 1:
The invention removes filters entirely from the system, replacing the filtration mechanism with solar thermal distillation. This eliminates the need for expensive filter materials and their periodic replacement, reducing both manufacturing cost and maintenance requirements.

AI summary
A solar powered water purifier (1) having a main reservoir (2) for holding unpurified water (18), a collection tube (22) supported within the main reservoir and an inverted conical-shaped lid (11). The conical-shaped lid captures evaporated water from the main reservoir in the form of condensation and directs the condensation toward the collection tube for collection, which diverts water from to outside of the main reservoir for storage and/or use.
