The Bondgraph had been used widely in building and simulating a model. This paper solves a problem in an attic hatch (planar mechanism problem) using Bondgraph approach. Planar mechanisms are idealized systems that can translate and rotate in one plane. In the same way as linear translation or uni-axial rotation, planar motions can be considered as a special case of spatial motions of mechanisms. In the attic hatch system, people have to push with lot of power to open it. Then came up an idea to add a mass-pulley mechanism in order to open and close it easily. Before implementing this idea, it needs to simulate it first, because it needs to adjust many parameter combinations. This will also prevent someone to make unnecessary hole while implementing this idea (such as trial and error). This paper only dealt with building and simulating this idea, not going further in the real implementation. The simulation result shows that several parameters should be chosen carefully in order to achieve the final goal, i.e. to open the hatch easily and fast. The 20-Sim simulation package is used to verify the model.
