Method of obtaining different mechanisms by fixing different links in a kinematic chain, is known as inversion of the mechanism.
Inversion of 4-Bar Mechanism
- Crank-Crank Mechanism : Coupling rod of locomotive
- Crank-Rocker Mechanism : Beam Engine
- Rocker-Rocker Mechanism : Watt's indicator
Inversion of Slider-Crank Mechanism
- First Inversion - link 1 is fixed : Reciprocating engine
- Second Inversion- link 2 is fixed : Rotary engine, Whitworth quick return mechanism

- Third Inversion - link 3 is fixed: Crank and slotted lever mechanism, Oscillating cylinder mechanism

| Crank and slotted lever quick return motion mechanism |
- Fourth Inversion - link 4 is fixed: Hand pump, bull engine

Inversion of Double Slider Crank
It has four binary links, two revolute pairs, two sliding pairs.

| Double Slider Mechanism |
- Link 1 is fixed : Elliptical Trammel
- Link 2 is fixed : Scotch yoke mechanism
- Link 3 is Fixed : Oldham Coupling
Oldham coupling is used to connect two shaft which has lateral misalignment.
