P07402: UV-Tube Water Disinfection Project/public/
Generate Product Concepts
Table of Contents
Functional DiagramA functional diagram was developed to show material and energy input/output. Also through this process, three sub-functions were identified:
- Water Input / Filtration
- Tube Cavity
- Power Systems
Initial Concept DevelopmentThe team participated in initial concept development, focusing on the three subfunctions identified above. Through branstorming and group discussion, the following ideas were initially developed/considered:
Concept Development RefinedThese concepts were further discussed and refined to develop several specific concepts, as shown below categorized by subfunction.
Water Input/FiltrationBoth batch and continuous flow were considered for water filtration. Five main concepts were developed:
- Terracotta Pot with Sand
- Fast Filtering Mesh
- Purchased Bag Filters
- Commercial In-Line Filters
Tube CavityThe driving idea behind the tube cavity concepts was to create a design which facilitates the construction and maintenance of the device. Material selection was also considered. There were two main concepts developed:
Power SystemsThere are two sources of power for the device. It may be connected to the grid (in a very similar manner to the current design), or powered from an alternative source. The alternative sources considered are solar and human powered DC generator input.
The DC Generator power concept necessitates a mechanical system to transmit mechanical power into the motor/generator. Several concepts were developed, and are listed below.
