16 Partial or excessive actions

If 100 percent of an object is hard to achieve using a given solution method then, by using 'slightly less' or 'slightly more' of the same method, the problem may be considerably easier to solve.
  • Apply silicone sealant in excess then smooth off the surplus with a caulking tool.
  • Fill, then top off when filling the gas tank of your car.
  • Laser-cut a metal part slightly oversized, then machine it down to the exact dimension.
  • 3D printing with support structures that are removed after the part has solidified.
  • Furniture assembly: partially tighten all screws first to align the parts, then fully tighten once everything is in place.
Principe 16 : Apply silicone sealant in excess then smooth off the surplus with a caulking tool.
