Task 1: Constraints
In a true design process, client and designer would collaborate to determine a list of constraints. For the purpose of this task, the designer presents the following five constraints to be placed on the design of an all terrain vehicle (ATV): the dimensions are not to exceed: width 130 cm; length 210 cm; and mass 320 kg; build cost is not to exceed $7,000; effective range (easy terrain, moderate speed) of 100 km with no additional power source; additional power must be portable; at least three cubic decimeters of enclosed storage capacity; and must operate reliably in temperatures from -40 ℃ to +40 ℃.
The purpose of the dimensional constraint is to ensure the ATV can be loaded into most pickup truck beds. In addition,

skidplate) - unwanted; illuminate terrain ahead - unwanted; play music - unwanted; provide audible warnings (e.g. a horn) - unwanted; and provide cold storage for beer - unwanted.
All secondary functions listed as “required” contribute in some way to the ATV’s ability to provide off-road transportation. Some form of energy is needed and it must be converted to kinetic energy. A driver and his goods require some separation from moving parts. The act of transportation requires the driver to have access to variable speeds, braking, and steering. All other functions do not contribute to the basic function. These “unwanted” functions provide additional comfort, and safety; or non-transportation based functionality.
Task 3: Design Tools A pairwise comparison chart will rank the objectives of the ATV design project. While the aforementioned list of functions is a summary of what the product will do, the objectives describe what the product is. The following pairwise comparison chart illustrates the designer’s view of goals for this project (no client in this
‘The strengths, weaknesses, opportunities and threats analysis often forms the bedrock of any product planning process. It provides a simple yet effective framework for analysing both internal resources and external trends and competitors’ (Pender, L, 1999: 179)
Snowmobiling in today’s world is far more exciting and dangerous than it used to be in the 20th century. There are many types of snowmobiles and different capabilities for every make, model, and year. Every single snowmobile is different in its own way. Many snowmobiles have evolved and developed into amazing machines that are a great source of entertainment.
In recent years, GM’s reputation as being one of the best automotive companies has been debated. The consumer has rejected some of their vehicle designs as
The ELF can travel at speeds over 25 mph, and the motor is geared low enough to handle climbing hills with ease. The battery has a range of 16 miles with no pedaling, and 30 miles with pedaling. It takes about 2-3 hours to charge using a normal standard wall outlet. Obviously solar charging times depend on the availability of sunlight. In direct sunlight it can be completely recharged in about 8 hours.
Motorcycle is also called motorbike is a two or thee wheeled vehicle powered by a petrol, diesel, engine mounted midway between the front and rear wheels. The motorcycle, which is having much heavier and stronger, frame than that of a bicycle. The motorcycle is developed from the bicycle. The people for their convenient and smooth travel for the recreation and sports purpose use the motorcycles. The motorbikes are used throughout the world, the police and the fire department use motorcycles to carry medical personnel to accident scenes. Before the 20yrs ago a motocycle was carried for the noise, dirt and frequent breakdown which the use of its entailed. It was then truly a sportsman’s machine and of little use in the commercial field.
But there appears to be an escalating problem with SUVs. As Americans thirst for more of the power and comfort they provide, we are refraining from using proper caution while driving SUVs. These vehicles provide a false sense of security for drivers when faced by inclement driving situations. Because of the feature of four-wheel drive, drivers automatically assume safety. These vehicles are also very dangerous to the other vehicles on the road. By observing the trends and facts one will see that Sport Utility Vehicles are a major cause of the increasing danger on the roads today.
Harley Davidson’s approach to the manufacture of motorcycles creates value as raw materials evolve into sellable products. The 40,000 square meter plant in Kansas City, Missouri is laid out in a fashion that permits the backward integration of components within the production facility. From the fabrication of parts to the production of engines onsite, a single V-Rod is built by the 1,100 employees of this factory in less than 3 hours from start to finish.
Initial projections show that the current schedule will take 50 weeks to finish with a final budget estimate of $3.152 million. Although the project estimate comes in under budget, the time frame for completion extends beyond the acceptable 45 weeks. Therefore, the following discussion takes a closer look at the project's conditions by developing a project priority matrix, project network, and a Gantt chart to help Bjorn Ericksen and his team reduce the project duration. The author then offers a project closure approach.
Off-highway vehicles (OHV), which include snowmobiles, four-wheelers and dirt bikes, are the mode of choice for millions of Americans who want to experience the outdoors. They're blamed for irreparable damage to the environment, and touted as one of the most enjoyable ways to spend time with friends and family outside. Environmentalists insist that much harsher restrictions of OHV use on public lands are vital to preserving fragile ecosystems. OHV users say they follow the rules already in place and don't need any more.
Today, Off-highway vehicle (OHV) use is one if the fastest growing recreation activities taking place on the public of the western United States. OHV includes, but is not limited to motorcycles designed for off road use, All terrain vehicles (ATVs), 4-wheel drive automobiles, and other vehicles such a sand rails or dune buggies (Cordell, Betz, Green, & Owens, 2005).
drivability, fuel economy, and cost of ownership. Legal requirements are focused on significant emission and fuel
Client(s) may be in the first stage of our design thinking sequences (Archer, 1984, p. 67), and then the designer job is to explore what is the problem, what do we want, what do they need: to produce a design to meet the requirements. The initial design problem presented to the designer may be poorly and incompletely described (McDonnell, 1997, p. 45...
Focus shall be on utilizing pre-production tools while developing the prototypes. Actual material, wherever possible, shall be used in the development of prototypes rather than having substituted parts. Make the prototypes as closer as possible to actual outputs.
SUV’s have become the center of a large controversy in the last couple of years. Many studies have been conducted on the relation to the economy and the popularity of the SUV. The sport utility vehicle not only affects the economy with its gas-guzzling capabilities during a time of war, but with the safety questions that have continued to arise.
The move toward a more aggressively styled and higher riding vehicles have caused unintended consequences and risks. The risks include decreased “drivability”, obstruction of vision, and concerns surrounding safety. Current trends in vehicle design focus on addressing these problems to achieve appealing designs with the best qualities of both cars and trucks, as seen in all the new designs from the Land Rover.
