- Abstract A mobile wireless charger is a device that charge a smartphone or other compatible gadgets without the need for physical cables. Principle of wireless mobile charger system based on inductive coupling phenomena. The main objective of this paper aims to address the challenge of packaging wireless mobile charger in peculiar door trim profile keeping overall functionality and aesthetic appearance of door trim intact. This paper deals with integration of a wireless charging system within the door trim of a vehicle to provide convenience and advanced functionality. The objective is to pack a wireless charger in door trim meeting the ergonomic target and equilibrium state stability while maintaining sleek and minimalist design of the door trim. The study focuses on innovative packaging solutions related to space optimization in door despite multiple challenges involved. Major challenge lies in packing the unit amidst complex mechanisms such as window regulators, speakers, structural reinforcements while managing the thermal heat generation with proper dissipation techniques Poor packaging could trap heat, affecting the performance and safety. Seamless integration into the trim enhances visual appeal and brand perception improving the overall premium feel of the interior. This paper explores the packaging of a wireless charger unit vertically in car door trim achieving equilibrium state stability. Not withstanding, this paper throws light on different strategies for Mobile stability to get maximum mutual inductance coefficient (M = (N2 * Φ21) / L1 = (N1 * Φ12) / L 2) between Mobile and Wireless charger mat which is directly proportional to charging percentage. KEY WORDS: M = Mutual inductance between two coils L1 = Self-inductances of the First coil L2 = Self -inductances of the Second coil N1 = No. of coil turn in first coil N2 = No. of coil turn in second coil Φ21 = Flux of first coil with respect second coil Φ12 = Flux of second coil with respect to first coil.
