Advice on Brand Name / Brand Registry

I sell on Amazon, and I have a brand that is trademarked and brand registered. It’s called “TILTECH”. It was originally a phone accessories brand, so that’s why it has “TECH” in the name. I have a new product that is a fun designed blanket. It has no special technology. Looking for advice. Should I just called it the TILTECH (insert rest of blanket name)? That way I’ll have registry, EBC, etc. Or should I make a more cutesy brand that fits for blankets and wait out the whole trademark thing / is there a way to get brand registered without that trademark?

I’ve heard that you can just show that it’s your product and that it has your brand on the product and that you have a website and they’ll approve your brand registry. Is that true? All input is much appreciated. Thank you!
