Electric Mobility Scooters 2INTRODUCTIONAs a sustainability manager for the manufacture of electric mobility scooters for the disabled, there is need to investigate to which the concept of The Circular Economy can be applied to the company and the products manufactured from the present linear energy and material flows. There is need of ensuring the sustainability of the manufacturing activities of the electric mobility scooters and also planning the future products and the business model of the company since all these affect the sustainability of the company. The major types of the components used in the manufacture of the electric mobility scooter can be categorized into electrical parts which include batteries, circuit boards, wires, switches, and motors, structural parts which include seat assembly, suspension, wheels, and chassis, as well as miscellaneous parts which include upholstery, bodywork, transmission, and tyres. These components are described below:Structural ComponentsThe major structural design elements of the scooters which are considered by the company include the convertible hood, seat assembly, chassis and suspension, and design layout.Chassis is basically the internal structural parts of the scooter which supports the wheels, steeringsystem, and transmission system. Both the rear and front wheels are connected indirectly to the frame of chassis by means of the suspension system which is attached to the wheels directly. Thematerials used by the company in the manufacture of the chassis frame include magnesium, titanium, aluminium, and steel[ CITATION Env10 \l 1033 ]. Steel is cheap and easily available and the availability and cost of the steel and the requirements required to process it are of major advantage for commercial production. The steel

The suspension system is a collection of shock absorbers and springs and can be of two types, namelyrear suspension and front suspension. This system insulated the electric mobility scooter and the rider from the shocks from the road and keeps the wheels in the closest contact possible with the ground hence providing control of the scooter to the operator. Currently, telegraphic forks are applied in the front suspension in the scooter which enables the front wheels suspense down and up hence providing a comfortable ride. The forks’ bottom is coupled to the front axle around which the front wheel rotates[ CITATION Jan12 \l 1033 ]. Figure 1: Suspension system[ CITATION Ema18 \l 1033 ]In steering geometry, the major parts considered include steering axis angle and wheelbase. The wheelbase determines the longitudinal stability of the scooter. The full body aerodynamics of the electric scooters is a significant design factor since it determines the lift and drag force of the vehicle. The drag force is majorly considered during the manufacture since the designer tends to decrease the drag of the system by making a huge front which slashes the air into numerous streams. The electric scooter is also incorporated with a convertible hood which provides protection of the operator against the advanced condition of weather such as sunlight, dust, and rail. The hood is supported on the top of the tyres which are positioned between rear

Some of the attributes incorporated and designed while designing seat assembly include foldable armrest of 90o, the seat can rotate 45o to assist in outguessing and ingress the person with the disability, and greater riding and seating comfort making the vehicle more comfortable and easy to operate[ CITATION Mar18 \l 1033 ]. Electrical ComponentsThe electrical components used in the manufacture of electric mobility scooters for the disabled include batteries, circuit boards, wires, and motors. The system is composed of two motors independently driving each major wheel through relays. The motors provide improvements in efficiency and performance. The source of power for this electric mobility scooter is a single battery which is kept on board of the scooter and is charged through an onboard battery charger unit from standard electric power[ CITATION Hou10 \l 1033 ]. The batteries manufactured in the company are the lead acid battery which is still the bestsolution in energy storage. The current improvements in battery monitors and chargers ensure a more reliable and efficient source hence increase improvising the lifespan if the battery and preventing flat battery. These rechargeable batteries enable the mobility scooter to travel more than 30 miles before the batteries become depleted. The circuit boards, switches, and wires used in electrical connection within the mobility scooter are supplied to the company from other manufacturers and then assembled in the scooter. The circuit boards used to depend on the type of disabled scooter model that the company is manufacturing at that particular time, the mobility
