Für die Plastik „Luftstütze“ dient mir eine Monstera deliciosa als Inspiration. Die Nodien und Internodien der Pflanze erinnern an ein erweiterbares, modulares System, aus welchem sich die Luftwurzeln herausdrücken und der Pflanze Halt und Stabilität verleihen. Die organische Plastik greift diesen Aspekt auf. Die frei hängenden Elemente verleihen der Plastik trotz eines gewissen Volumens eine Leichtigkeit und gleichzeitig Stabilität.

This thesis describes the optimization process for the pitchfork developed by the company Sverigegrepen. The work was done at the department of Applied Mechanics at Uppsala University. The project were handed by Ångström Materials Academy together with Sverigegrepen The work included a major prestudy of plastic construction, plastic materials, plastic injection and strength of materials. By applying the laws of beam theory, a mathematical expression could be provided, explaining the behaviour of the pitchforks teeth. By studying the pitchfork with tools such as 3D- CAD and FEA-simulations, an area where high concentrations of stress were found, an area known to have frequent issues with strength. From this data several concepts were created with an increased strength and a better distribution of stress. The plastic material was evaluated and tested to find the most valuable material characteristics. The provided information was used to isolate different functions in plastic materials, which is crucial for the pitchforks further functionality.
