Many varieties and shapes of computer video monitors now exist. Their long-term use leads to eyestrain and body fatigue. There is a need for an adjustable stand which will hold the video monitor and the separate keyboard at any position the user deems comfortable. The computer’s central processor unit (CPU) can be remotely located. This device should be freestanding to allow use with a comfortable chair, couch, or lounge of the user’s choice. It should not require the user to assume the conventional “seated at a desk” posture to use the computer. It must be stable in all positions and safely support the equipment’s weight.

We planed to design a freestanding monitor and keyboard stand which can solve the problems and meet customers’ needs. A majority of people felt a middle or higher discomfort because of the position of their computers. Many expressed their desire to buy a product to solve their problem, with average max price at 188RMB. So basically there is a large number of potential users. We investigated various aspects they focus on, and drew a QFD diagram, which indicated the degree of freedom, or mobility, to be most important. It should be comfortable and friendly to use. Weight and size are also main factors, and we need to ensure strength of structure, to ensure safety. Material selection is of the same level and will influence the factors mentioned. Although appearance is the least emphasized. We will make a design to make it attractive to users.

Also, we need to select materials, do simulations and application preview to make sure it meets those requirements, and make a manufacture plan with proper cost.

After teamwork throughout the whole semester, we finished all the designing, modeling and optimizing work of our project. By function assessment in SolidWorks software, we can state that the Adjustable Computer Stand will effectively solve the technical problems that the present similar products cannot be horizontally placed in the slope field environment and are single in usage and storage. The final prototype will meet our initial requirements of Comfortability, Sturdiness, Durability and firmness. In addition, by cost estimation, we prove that it has its market prospect. Although we cannot manufacture the prototype in reality, we still list all the assembling and manufacturing methods of different parts in detail considering both cost and performance.
