Discarding and Recovering is usually applied as follows:
1. Making portions of an object that have fulfilled their functions go away (discard by dissolving or evaporating) or modify these directly during operation.
a. i.e. Use a dissolving capsule for medicine
2. Conversely, restore consumable parts of an object directly in operation
a. i.e. Self-sharpening lawn mower blades
In other words, Discarding and Recovering aims to make things go away after their use has been fulfilled, or repairs itself so that the part does not need to be replaced.
Medical practitioners utilize this principle daily. Consider dissolvable stitches, also known as absorbable sutures, and screws that dissolve in surgery. Absorbable sutures are made of materials that break down in body tissue after a known period of time. The disappearing aspect of the stitches is an advantage, especially when the stitches are used internally, because there are no foreign objects left in the patient’s body. There’s also no need for follow-up appointments to remove the stitches or screws because the apparatus discards itself.
Temporary tattoos are another example. The body art serves a temporary purpose, and then disappears after a few days. Breath strips work in a similar manner. The breath strips serve a temporary purpose, to alleviate bad breath, and then dissolve in your mouth.
Dry ice blasting is a popular process for preparing or cleaning a surface. Dry ice blasting is similar to sand, plastic, bead, or soda blasting, but with one distinct advantage. This process utilizes dry ice particles, which are made from carbon dioxide. When the dry ice particles fall on the ground, they disappear because dry ice sublimes at room temperature. As a result, there’s no residue or mess to clean up, because all of the blast material has disappeared.
Can you make an unnecessary aspect of your product or service disappear after its use has been fulfilled?
