Abstract
A pressure disintegrable device includes a first volume that further includes a first portion and a second portion. The first portion is adapted to transmit a pressure applied to the first volume to a second portion disposed on the first portion. The second portion is adapted to decrease a melting point thereof as the transmitted pressure increases beyond a predetermined pressure. The pressure disintegrable device may also include a layer disposed on the first volume that is adapted to create a seal between the first volume and an external structure.
Claims18
A pressure disintegrable device, comprising:
- a first volume comprising:
- a first portion adapted to transmit a pressure applied to the first volume to a second portion disposed on the first portion,
- wherein the second portion is adapted to decrease a melting point thereof as the pressure increases beyond a predetermined pressure;
- and
- a layer disposed on the first volume and adapted to create a seal between the first volume and an external structure.
A method of operating a pressure disintegrable device, comprising:
- applying a pressure to a first volume comprising a first portion and a second portion disposed on the first portion,
- wherein a layer is disposed on the first volume and adapted to create a seal between the first volume and an external structure;
- transmitting, by the first portion, the pressure to the second portion in response to a pressure applied to the first volume;
- decreasing, by the second portion, a melting point of the second portion in response to the transmitted pressure;
- and
- changing, by the second portion, a state of the second portion from solid to liquid in response to the decrease in the melting point of the second portion.
A method of producing a pressure disintegrable device, comprising:
- obtaining a first plurality of grains of a first material;
- obtaining a second plurality of grains of a second material that decreases a melting point of the second material as an applied pressure increases beyond a predetermined pressure;
- forming a first volume by:
- forming a first portion by consolidating the first plurality of grains;
- and
- forming a second portion, disposed on the first portion, by consolidating the second plurality of grains;
- and
- applying, to the first volume, a layer disposed on the first volume and adapted to create a seal between the first volume and an external structure.
