Utveckling av personlyft till badkar
This thesis is performed as a summarizing project for the mechanical engineering education at School of Engineering in Jönköping. All knowledge necessary to complete this thesis was gathered from previous courses and education.
This project was to develop a new product for the company TR Equipment AB in Tranås. The new product is going to be based on an already existing product, TR 1700. TR 1700 is a bathtub equipped with a height adjustable function. This product is used in retirement homes and in the care of disabled people. The height adjustable function limits the stress needed to lift and assist the bather when using the product. This gives a better work situation for the caretaker. Our goal is a functional and attractive product designed and built with existing parts available from TR Equipments other products. If the timeframe allowed the method of DFM/DFA (Design For Manufacturing/Design For Assembly), be applied so that the company could start production on the product as soon as possible.
An analysis of different competitors in the same market was conducted. Result showed that the most of the competitors were foreign. The main market for this product is outside Sweden.
Specifications for the new product were drawn up, the new product should have a lift to transport the user in and out of the bathtub. Different concepts were generated and one dominant design was chosen for further development.
The next step was to choose the final design, from the new sketches made from the chosen design from the first round. Color is very essential for a product and the group decided to implement the red color found in TR Equipments previous products but in a new, more distinct way to highlight important functions, safety features and logotypes.
Ideas and solutions concerning the attachment of the chair into the lifting arm, and the design and function of the arm itself, has been included in the report. The thesis is for the most part focused on the design element of the product.
After working through all the steps and methods of product development a functional product with a clean, hygienic and practical design was constructed.
