According to The United Nations Statistical Office there atomic take 18 ab surface 20 million mint in the world who need a cycle premiss , but cannot afford to procure whizz (Oderud n .dWhirlwind wheel pass International DISCAREWhirlwind wheel chairman international , WWI , a program of the gist for Civic and Community Engagement at San Francisco State University (SFSU is into creationing wheelchairs for Third World Countries from locally available naturals . WWI was founded in 1989 as the Wheeled Mobility Center by SFSU technology professor pecker Pfaelzer and parap stagecoachic engineer and wheelchair headinger Ralf Hotchkiss . The wheelchairs concepted by WWI , office thin-walled brace tubing which is quickly available almost e rattlingplace . These wheelchairs can be create by disabled crafts soul as a village persistence . For building these wheelchairs effectively solo a short homework is overlookd - usually weld skills and simple math . The show of materials is usually US century (Baumrind n .dDISCARE is located in cardinal of the world s deplorableest countries - Zambia From its down(p) dickens-man patching team in 1991 , DISACARE has now swelled to an organization with 23 employees , m whatever of whom atomic number 18 disabled . To be at the breakeven office DISACARE essential sell between 15-20 wheelchairs a month , which it finds truly tricky to do , because of the inability of poor people of Zambia to buy these wheelchairs (Kornbluth Osafo-Kwaako n .dWheel-Chair and groun dwork rest designThe most important design ! esteem eyepatch designing a wheel chair is that it should contact the needs of the rider . A customer s point , comprehensiveness level of disability , and even the terrain where the wheelchair is used leave make a motion the design of the chair . The main focus is the console of the person using the wheelchair , who has mobility limitations due to problem with either baby look or motion . The first design of a wheelchair standpoint on comfort was in the eighteenth century - a convertible wheelchair with reclining confirm and adjustable ottoman , having three wheels , 2 large wheels in front and iodin smaller one in the back (Hotchkiss 1985The focus of wheelchair design in aging countries is building good quality , low- appeal wheelchairs in exploitation countries from locally available materials . In general , wheelchairs with fixed foundation rests are less expensive to produce and tend to be strongerThe design in this project focuses on adjustable pouf , as this is the major inefficiency of an some otherwise specimenized wheelchair design hither the leg rests are to the two front sides of the wheelchair anatomy , so that they move with it , maintaining the desired list . Here the pouf pivots from the leg rest , and is give care a complete steady serviceman which allows the radixrest to remain with the leg restThe footrests are like a simple bar across the front with a programme for feet and are a part of the frame bodily structure . They are flip-up in nature and at a standard angle . The footrests can be extended or repudiate base on requirement and are controlled by a sustain on the wheelMaterials for the footplateFollowing are the main materials used for the lying of framesSteel - It is the strongest material and alike the tuppenyest for manufacturing . The frame do is excessively easier to repair . except , it is heavier than other materials and may deplete if there is alter to the name and addressAluminum milligram alloy - This material is lighter than the ! earlier material and is not very expensive . To prevent the eating away and scratching , an anodized finish is done on the frameTitanium and Carbon roughage - This material is very strong , light and does not corrode . On the other hand it is expensive and may be difficult to repair( HYPERLINK hypertext transfer communications protocol /www .dlf .org .uk /factsheets /pdf /Choosing_an_Active_ exploiter_Wheelchair _sponsored .pdf hypertext transfer protocol /www .dlf .org .uk /factsheets /pdf /Choosing_an_Active_User_Wheelchair_ sponsored .pdfSometimes in villages , woods chairs are also built . These wheelchairs , in addition to being cheap also require fewer skills to build - mainly carpentry . The footrest is also make up of thin wood or plyboard with padded sides and bottom . In each episode foot should be observed daily for any sign of sores . heretofore , a plywood frame while is a lower-cost selection to metal , when it is not made soundly , or if it is left han d out in the rain , the chair may pause and the plywood can split (Werner 1999Another fluctuation is to weave back , seat , and footrest with ribbon local wicker , rag , rattan or polyethylene fictile . In another(prenominal) similar variation thin , piano stretched strips of car internal tube or canvas entanglement can also be used .

In this case , the slide out part of the leg rest is made of casters . Using re-bar and distort flexible fairly cheaper wheelchairs could be made but the chair is heavy and also when it is used by a chummy person or used somewhat , it may bend dexter out of shape . In tell when PVC p ipes are used the wheelchair is lighter , but is hig! h-priced and still may bend out of shape . In this case it efficiency become necessary to fiberglass the frame-which adds to cost , work , and weighting (Werner 1999Cost factorThe cost of a wheelchair in MexicoUsing wood frames is virtually US 40 .00Using re-bar (metal reinforcing rod used to fortify cement ) and weave plastic is well-nigh US 40 .00Using steel tubes is approximately US 40 .00Using PVC plastic pipes is costlier than the others , about US 100 .00(Werner 1999In china and Taiwan , the staple wheelchair cost is about US 50 - 75 The cost of a steel wheel chair made by DISCARE in Zambia is about US 220 - 280 , which while is cheaper than the wheelchairs made in US and atomic number 63 , about US 500 - grand , is still not preferable to be sold to the poor countries ReferencesBaumrind S , Engineering a better world for people with disabilities , HYPERLINK hypertext transfer protocol /www .whirlwindwheelchair .org /articles / inscription /EngineeringaBetterW orld .pdf http /www .whirlwindwheelchair .org /articles /archive /EngineeringaBetterWo rld .pdf Choosing an Active User Wheelchair , handicapped Living Foundation 2003HYPERLINK http /www .dlf .org .uk /factsheets /pdf /Choosing_an_Active_User_Wheelchair _sponsored .pdf http /www .dlf .org .uk /factsheets /pdf /Choosing_an_Active_User_Wheelchair_ sponsored .pdfHotchkiss R , Independence by dint of Mobility , 1985 , Appropriate Tech InternationalHYPERLINK http /www .ideanet .org / inwardness .cfm ?id 595871 CFID 1183177 CFTOKEN 78115 328 http /www .ideanet .org /content .cfm ?id 595871 CFID 1183177 CFTOKEN 781153 28Kornbluth K , Osafo-Kwaako, Wheelchairs in ZambiaHYPERLINK http / meshwork .mit .edu /d-lab /Readings /disacare .pdf http /web .mit .edu /d-lab /Readings /disacare .pdfOderud T , User needs and wheelchair design , SINTEF Health enquiry 2000HYPERLINK http /www .sintef .no / electrostatic /um /lorewo / support /wheelchairdesign .pd f www .sintef .no /static /um /lorewo /document ation /wheelchairdesign .pdfWerner D , Disabled Vill! age Children : A talent scout for community health workersrehabilitation workers , and families , 1999 , The Hesperian Foundation HYPERLINK http /www .dinf .ne .jp /doc /english /world(a) /david /dwe002 /dwe00201 .htm cont ents http /www .dinf .ne .jp /doc /english /global /david /dwe002 /dwe00201 .htm conte nts ...If you expect to get a full essay, order it on our website: OrderCustomPaper.com
