Using The Design Tools Available To You: Plan Your Project ✓ Solved
Using the design tools available to you plan your project
Using the design tools available to you, plan your project using a design model (e.g., Pahl and Beitz, MAE) to fully investigate the brief and develop a solution to the problem. This is to help develop your Global Awareness in Engineering and to help define the problem.
Globally conscious engineering: Produce plans for an innovative irrigation system that will bring water from a nearby pond or river to water your vegetable garden. It must be operable by an 8-year-old and allow villagers that cannot access a clean water supply the opportunity to water their crops. It should give a flow of 0.1l per minute per sq. meter of crops that are being grown. It must have the option to switch it off should the crops begin to become saturated. It must be protected as much as possible from vandalism.
The device must be manual mechanical and not use electronics in the form of solar panels as they are a target for thieves. Plastic parts are also preferred for this reason as steel has a high resale value. Where possible it should use freely available plumbing components that may be available locally. It should require minimal servicing and have easily repairable parts.
The submission requirements are laid out below and which section of the MAE Design Model they fit into. All drawings are to be drawn on A3, and you will need to find university facilities that allow you to scan this size into your document. Use Adobe Acrobat to collate them. All drawings to use BS8888 technical drawing standard. As part of the final drawing package, as a minimum I would expect to see one isometric assembly drawing (with annotations) and one orthographic assembly drawing (with annotations of finishes, movements, assembly dimensions, etc.). All concept drawings should be in isometric.
You are not constrained to using CATIA; you may use any CAD package you’re comfortable with. Google Sketchup or Autodesk Inventor are recommended. To achieve higher marks on the drawing section: work hard, ensure detail drawings are necessary, use correct lines and line types, and dimension efficiently and thoughtfully.
What you should submit: 1000-word report minimum (word count excluding references, figures, and charts).
Paper For Above Instructions
The process of designing an innovative irrigation system involves a comprehensive understanding of both the engineering principles and the user needs, particularly within the context of global consciousness. The aim is to create a solution that is functional, efficient, and sustainable. The goal is to develop a manual irrigation device that can serve areas lacking access to clean water. Through a detailed design process that encompasses various methodologies, the final product should not only meet the operational requirements but also emphasize minimal environmental impact and ease of use.
Investigation and Definition of the Problem
The first phase of the design process is to investigate and define the problem thoroughly. Access to clean water is a critical issue in many parts of the world, particularly in developing regions. The irrigation system must facilitate the transportation of water from nearby natural water sources, such as ponds or rivers, directly to vegetable gardens maintained by local villagers. The operation should be simplistic enough for an eight-year-old child to understand, effectively enabling communities with limited access to technology to utilize it.
Constraints must be identified, such as environmental considerations, the sustainability of materials, health and safety standards, and the cultural appropriateness of the device. Additionally, the system should adhere to guidelines that discourage electronic components due to their vulnerability to theft. Consequently, using primarily plastic materials for construction will ensure that the system remains affordable and accessible.
Understand Customer and User Needs
The need for a manual, mechanical irrigation system that is easy to use stems from the target demographic—villagers with potentially minimal access to education and technology. Key features of the design must include a water flow rate that meets agricultural needs (0.1 liters per square meter per minute) and a mechanism to shut off the water supply to prevent crop saturation. This requires careful planning to ensure that the irrigation system can operate efficiently without causing damage to crops or deformation of the soil.
Use of Creativity in Solution Establishment
Designing an irrigation system necessitates creativity and innovative thinking. The initial brainstorming stage may include various ideas, such as gravity-fed systems, siphons, or handheld devices that allow users to direct the flow of water manually. Evaluating the feasibility of these concepts through market and literature review will provide insight into existing solutions and reveal gaps that the new design can fill. The Pugh Matrix will be utilized later to compare these concepts based on criteria such as ease of operation, cost, materials used, and potential environmental impact.
Concept Development and Evaluation
Three unique concepts will be developed and documented in detail. These concepts should draw upon existing technologies but adapted to the specifics of the context in which they will be deployed. A comprehensive comparison must be made to ascertain which concept aligns best with user needs and the constraints identified earlier. This step is critical to validate the direction of the design before moving toward the selected concept and justification.
Drawing Package and Final Design
For the drawing package, the final design should include isometric and orthographic assembly drawings that conform to the BS8888 standard. These drawings will represent the assembly process, provide necessary technical details, and include annotations describing materials and functionality. Each drawing must be meticulously crafted, dimensioned correctly, and visually clear to ensure that they communicate effectively the assembly and functionality of the product.
Discussion of Final Design
In discussing the final design, emphasis should be placed on aesthetics, materials selected, and ease of functionality. Concerns regarding production, maintenance, and disposability must be evaluated, ensuring that every aspect of the design is sustainable and practical for the user. An environmentally-conscious approach should underpin the discussion, reflecting a commitment both to the solution's feasibility and its broader social implications.
Conclusion
Through investigating the problem, understanding user needs, applying creativity in solution generation, and developing a thorough design and evaluation process, the project aims to create a viable irrigation solution that responds to the pressing global need for clean water access. The adherence to engineering standards and a focus on sustainability throughout the stages not only guarantees functionality but also fosters a spirit of conscientious engineering practice.
