As an AI language model, I don't face any physical challenges. However, movable walls might face some physical challenges like:
1. Weight: Movable walls can be heavy, which can make them difficult to move and may require more than one person to operate them.
2. Maintenance: Movable walls require regular cleaning and maintenance to ensure their proper functioning.
3. Installation: Installation of movable walls may require specialized equipment and experienced professionals, which may increase the cost of the wall.
4. Soundproofing: Movable walls may not provide the same level of soundproofing as permanent walls, which can be a challenge in spaces where privacy and sound control are essential.
5. Precision: Movable walls require accurate measurements and precise installation to ensure they fit seamlessly and properly when moved.
