Sony patents fluid-based system to control resistance in devices
Sony describes a mechanism that uses fluid pressure to adjust the resistance of a device. It features a flexible component that changes the size of a hole, thereby controlling how easily fluid can flow through the system.
In the filing’s own words
To provide a reaction force controlling apparatus and a reaction force controlling system that excellently control a reaction force. [Solving Means] A reaction force controlling apparatus according to the present technology includes a first deformable body, a base, and a second deformable body. The first deformable body includes a first space inside of the first deformable body, the first space having a variable volume. The base includes a second space that communicates with the first space through a circulation hole, and a third space that does not communicate with the first space or the second space. The second deformable body separates the second space from the third space, the second deformable body being deformed to change the opening area of the circulation hole, the deformation being performed due to fluid flowing into the third space or flowing out of the third space.
What exactly they claim (claim 1)
1. A reaction force controlling apparatus, comprising: a first deformable body that includes a first space inside of the first deformable body, the first space having a variable volume; a base that includes a second space that communicates with the first space through a circulation hole, and a third space that does not communicate with the first space or the second space; and a second deformable body that separates the second space from the third space, the second deformable body being deformed to change the opening area of the circulation hole, the deformation being performed due to fluid flowing into the third space or flowing out of the third space.
