Lucjan Łągiewka (born 29 July 1949 in Kowary, Poland ) - Polish inventor and constructor. The inventor of (among other things) so-called "Lagiewka's bumper". It is a device, a kind of collisions shock absorber, which converts part of the kinetic energy of a moving object into the kinetic energy of rotation of the rotor EPAR device (Energetyczny Przetwornik Akumulacyjno-Rozpraszający, Accumulative-Dissipative Energy Converter), which allegedly can significantly reduce the forces acting on an object during impact and be a competitive option to current solutions [1] [2]. Hypotheses of inventors on the bumper have not been published in scientific journals and have no scientific confirmation [3]. At the moment, there is no mass-produced device that uses EPAR.

Associated with the project Stanisław Gumuła postulates that the bumper's action is inconsistent with the principle of d'Alembert [1], therefore, undermines the foundations of modern physics, and that the operation can not be explained by the known laws of physics [4]. The invention is the subject of criticism due to hypotheses of the authors about it's actions that contradict principles of physics. As well, due to unproven and questionable effectiveness of practical, in particular the postulated superiority over existing solutions, this invention is under criticism [5] [6] [7] [8] [9]. The invention of the Lagiewka's bumper initiated the creation of the EPAR project that develops the concept of the Accumulative-Dissipative Energy Converter and plans to introduce it to the consumer use. Stanisław Gumuła is the co-author of EPAR [10]. Lucjan Łągiewka and project EPAR for their invention were honored by (among others): Award sponsored by "Gorodissky & Partners'" company from Russia [11] and Economic and Scientific Innovation Fair Award INTARG - Katowice, Poland 2003 [12].
