Ergonomic Student Laptop Desk Design Using the TRIZ Method

Students are among the most common users of laptop devices. With the variety of activities done by students using their laptops, many issues are faced because the physical interaction between user and laptop is not well designed. This research aims to produce a laptop desk design for students. The study was conducted with 30 undergraduate and postgraduate student subjects in an integrated campus environment of Universitas Islam Indonesia. Based on the results of questionnaires given to the subjects, six main problems of the laptop desks were identified: storage, lack of additional functions, lack of laptop mats, complaints while typing or using laptops, and complaints of neck pain. An analysis was done to find a solution using the TRIZ method. The TRIZ analysis tools used were cause and effect chain analysis (CECA) and engineering contradiction. The validation of the success of the solution was determined by using a homogeneity test with P > 0.05. This shows that there is no difference between the solutions given to the table design in terms of consumer expectation.
