A product that is accessible and sustainable should enable as many people as possible to use it and have a long-life length. Accessibility in product development is called Universal design. These products should be developed so that they are effortless to operate no matter the age, gender, or eventual disability of the user. Tilting a bike carrier to access the tailgate can be a demanding process for certain people if it is heavily loaded. If the user fails to withstand the loads, high impact forces can occur. An ergonomic design could prevent users from being injured. It could also prevent bikes and carriers from being damaged. This research tries to answer the question of which the optimal design for an ergonomic and sustainable tilt function is. It aims to develop a concept. From this concept a prototype to perform validation tests on will be made. With a quantitative method, data is gathered through a document study and a mathematical model. Based on this data, several requirements for the concept are established. The concept is then developed to fulfill these requirements. The result is a tilt mechanism which consists of compression springs that pulls the carrier into a horizontal position. The result is considered to answer the research questions. This is based on the test results which shows that the operator can tilt the carrier using forces beneath recommended ergonomic values.
