Abstract
This 4th semester master project concerns the design of a support system for hydraulic rescue tools used by firemen to free persons trapped in cars in automotive accidents. The research and analysis phase contributes to the foundation of the project through the use of situated interviews, observing drills, analyzing theoretical training manuals and DVDs etc. On the basis of the research and analysis, a problem is stated: How are the tools supported and procedures improved resulting in higher performance, more precision and less physical strain? In the concept generation phase, a concept based on integration of known proven technologies is formulated on the basis of a sketching workshop and further investigations. The concept evolves in the concept development phase by the use of sketching in combination with 1:1 working models that validate and explore design proposals through and empirical approach. The concept is detailed and documented by means of 3D modeling. As a result, Hydra - Hydraulic Tool Support System is presented. A support system that through a harness in combination with a load-bearing arm relieves the operator of physical stress. With Hydra, the operator is able to work faster, more precise and with more endurance.
I dette 4. Semester master projekt designes et bæreselesystem for hydrauliske redningsværktøjer, der bruges af brandmænd til at befri mennesker, der er fastklemt i biler på grund af færdselsulykker. Analysefasen skaber grundlaget for projektet gennem brugen af situated interviews, observering af øvelser, analyse af teoretisk materiale såsom træningsmanualer og DVD’er osv. På basis af analysefasen formuleres et problem: Hvordan understøttes værktøjet og procedurerne forbedret med højere ydelse, mere præcision og mindre fysiske belastning som følge? I konceptgenereringsfasen skitseres et koncept baseret på integration af kendte afprøvede teknologier baseret på en skitseringsworkshop og yderligere undersøgelser. Konceptet udvikler sig i konceptudviklingsfasen ved brugen af skitser i kombination med fuld skala forsøgsmodeller, der validerer og undersøger designforslag gennem en empirisk tilgang. Konceptet detaljeres ved hjælp af 3D-modellering. Som et resultat er Hydra – ”Hydraulic Tool Support System” præsenteret. Systemet understøtter det tunge værktøj ved hjælp af en bæresele i kombination med en lastbærende arm, der afhjælper brugeren for fysisk belastning. Med Hydra kan brugeren arbejde hurtigere, mere præcist og med mere udholdendhed.
