Design of a universal mounting system for flat panel TV screens

Abstract

In compact living spaces like micro-houses and apartments, there is a growing interest in décor and furnishing that utilize multi-functional systems and furniture. Of particular interest is the ability to facilitate the transformation of room setups, allowing for changes in the viewing positions of TVs regardless of alterations in room orientation. A thorough examination of the problem area uncovered several shortcomings in current market designs. These include limited adjustability, where fixed TV mounts mounted on walls or ceilings lack flexibility, making it difficult to achieve desired viewing angles without dismantling and reassembling the setup. Additionally, there are issues with limited compatibility, as some TV mounts fail to adhere to established VESA standards, a universal mounting standard for flat panel displays. Furthermore, many modern TV mounts lack additional functionality, such as cable management, resulting in cluttered and unsightly cable arrangements. The objective of the master thesis project is to develop a full-motion universal mounting system for flat panel displays that addresses these challenges. The system will be designed to be easily mountable and capable of supporting large and heavy television sizes. Utilizing 3D modeling software, such as SolidWorks, the product was meticulously designed to meet all design requirements. Additionally, Granta EduPack was employed to select the optimal material for the TV mount that is light, cheap and strong ensuring durability and safety. An extensive analysis of the product was performed on the compound beam of the product to validate whether the product is strong enough to withstand the design load of 55” – 70” flat display. The section modulus was identified as the contributing factor to the higher stiffness of the beam produce reduced deflections. With the aim of a minimizing weight, the minimum design cross-section of the beam was obtained by means of the safety analysis criterion. The cross section of the beam was optimized to accommodate the design load and also help reduce manufacturing and material cost and usage.
