All persons with injuries sustained, who have deprived them of their normal way of life, should be entitled to care and assistance. Unfortunately, that's not always possible. Also, a number of injured people want to continue their lives as soon as possible, as well as before the injury, and do not seek the help of others. In order to make these people easier to carry out their daily tasks, it is necessary to monitor their normal day and to spot the scope for a possible improvement. One such example is a wheelchair. In particular, persons who are in wheelchairs manage their own car and thus increase their mobility. The biggest challenge they face is getting in and out of the car with the need to ride a wheelchair with them. The folding chair does exist, but the full potential of one such product which could enable additional space saving and easier manoeuvre with parts is not used. Following an analysis of the wheelchair market and the perceived advantages and disadvantages, it has shown that the element with the largest adjustment space is precisely the wheel. As the wheel is the most difficult part of the wheelchair to handle with, it has been decided that it will try to improve. Setting the function structure and the morphological matrix of the wheels, each element of which the wheel is composed got its function which fulfils and their interrelationship when using the wheels has beed defined. Two concepts are designed to perform all functions of the common wheel with additional assembling the same. Observating the most significant criteria, such as the cost-effectiveness and complexity of the performance, evaluation was carried out on a separate basis and a relationship between them. Comparing the results, it has been showed that the concept 2 is more likely to continue analysis and develop. The modelling and analysis of the general concept 2 have obtained a complete look for the final product with the corresponding dimensions. The wheel has been tested under an overload of 750 N, which would correspond to a load capacity of 150 kg for two wheels in pair as they function. Using this analysis materials needed to ensure that the whole structure is stable were determinated while saving the mass which is among the most essential characteristics of the foldable wheel.
