There are basically two ways to connect the seat and its frame. Seat leg Part Alternative 1 Alternative 2 Geometry Solid Hollow Leg and seat connection Connected Independent More same as the main stick geometry, hollow tube is preferable than solid tube simply because the strength to weight ratio of a hollow tube is better than that of a solid tube.
Hence, the hand grip shape is the preferable shape for the handle. For the none structural part, for example the seat and the umbrella cover, light weight but low cost material such as plastic or other polymer will be selected as the building material.
For example, the surface area of a 30mm diameters square tube is mm2 but the surface area for a 30mm diameter cylinder is mm2.
The base area of the stick is larger when the seat is open thus increase the centre of gravity to make it more stable. Therefore, for cost and weight conservation and providing more spaces for other components, screw is the better method for connecting the seat and its frame.
We design the stick based on two purposes where people can used to support their body at the armpit or just used the hand rest as a usual walking stick. They used it to support their body weight and assist them when walking.
Combined Cane and Umbrella Drawing: Provide a stick which does not heavy in weight and long lasting. The seat that we design is light in weight and stable enough to support the user weight. Being independent is much harder than we think; Lucia and Frankie showed it to us every step of the book.
The walking stick that we design has the combination of seat and umbrella. Square tube consumes more spaces than cylinder with the same strength. Although the first method makes life easier, it does consume more material and add weight to the product.
Material Selection Below is a list of parts in this product and the selected material for building the part: A seat that is stable enough to support the user.
Apart from rich functionality, our product also is very stable when sit on and it also has a handle that help user to stand up which is another great accessibility feature.
The walking stick that we design is also has the handle which can be used to support user weight at armpit. It is multipurpose product.
The holes and key mechanism is simple to use, the design is simple and the fabrication process takes less time than building the thread mechanism. Advises from lecture -En.
For the geometry selection, hollow material with at least 3mm wall thickness is preferable compare to solid. This stick also has an adjustable height so that people can adjust the height based on their height.
But as the same case as the seat, ergonomics and user friendly is given the priority when designing walking aid for the disable, therefore the one piece leg method is the preferred method.
Combined Walking Stick and Seat Drawing: Constraints and performance target would be set after the functional requirements are generated so that the product design will meet the customer requirements and at the same time can be manufactured in a cost effective and efficient way.
The user does not have to worries about any unconditional situation happen in the future. The adjustable height is to ensure that people with several of height can use it.
The umbrella we design it in the stick so that it can be easier to bring and the user can used it at any time. Lecture note and lecture presentation 4.
Rectangle seat is the preferable choice because users comfort, ergonomics having more weight than the small amount of saving in material and weight.Jun 10, · The CATIA Version 5 Part Design application makes it possible to design precise 3D mechanical parts with an intuitive and flexible user interface, from sketc.
EMD CONCEPTUAL DESIGN AND CAD WALKING STICK WITH SEAT AND UMBRELLA Abstract Some people use walking stick to assist them when walking because their leg is not strong enough to support their body weight or.
