Retrofit hanging and freestanding smart interactive punching bag designs

Primary: Need retrofit hanging and freestanding smart interactive punching bag designs. Need universal designs for a smart wrap or sleeve that people can use to quickly wrap I.e., retrofit their existing punching bags. This would turn them into smart punching bags because the wrap is an interactive smart wrap with various sensors embedded into it. Designs for both residential and commercial places. Secondary: Should have the possibility of including a rechargeable battery back. Universal cellphone holder for users to tuck in their phones but is accessible and visible. Also possibility of holding a universal battery packs of various sizes. They should be in a place where there is least amount of whipping from punches and kicks.
