Wand of mount or a summoned creature. Force the mount into the dungeon and watch it spring all the traps. I once had a summoner in my party who summoned ponies to charge through the dungeon and set of any traps or encounters before we went through. Poor kobolds never saw that fiendish pony coming...
On one of my characters I used keep a few sets of bombs for dungeoneering and safecracking. Fireworks, alchemical items, and a few bombs just in case I one day find a use for them and the GM allows me to blow up whatever I want.
Grapple hook on a rope. From a safe distance, throw the grapple hook over the trap, snag it and trigger it. If it is a pressure trap that cannot be hooked, put some weight in a bag, tie it to the rope, throw it over, and drag it on top of the pressure plate. Other types of traps, if you can spot the trigger, you are a zen archer. Ask the GM what the AC of the trigger is, and hit it with an arrow. Since all these methods are unconventional, you will probably need the GM to agree that these common sense solutions will work. Some are strictly RAW, and then there is not much you can do but trigger it yourself and try to run.
