Cooling system for a shoe sole using additive manufacturing (English)
Abstract [sv]

Innovation genom additiv tillverkning sker snabbt i dagens industri där snabb prototyptillverkning är något som additiv tillverkning lämpar sig bäst för. Däremot utforskas möjligheter för tillverkning av detaljer med funktionellt syfte då additiv tillverkning möjliggör mer komplicerad design än traditionella tillverkningsmetoder. Med de miljöproblem som förekommer i dagens samhälle ger det upphov till extrema väderförhållanden, exempelvis skogsbränder. Givet det så har detta projekt utforskat möjligheten av att genom additiv tillverkning konstruera en sula med ett inbyggt kylsystem i syfte att kyla foten under förlängd arbetstid i omgivning med hög temperatur.

Kravet som ställdes på sulan var att i en omgivning med hög temperatur skall sulan kunna kyla mer än en traditionell sula över en period på 8 timmar. Med hjälp av CAD- och FEM-program analyserades tre primära modeller med avseende på temperaturutväxling samt belastning, varav dessa tre modeller ställdes i relation till en traditionell sula utan kylsystem. Resultaten hänvisar till att med de krav som ställdes på sulan ges en högre kylningseffekt vid två av tre av dessa modeller relativt en traditionell sula. Dessutom finns potential för fortsatt utveckling av liknande sulor med avseende på specialtillverkning.

Abstract [en]

Innovation through additive manufacturing occurs quickly in today’s industry where rapid prototyping is something that additive manufacturing excels at. However, research is being made to explore the ability for manufacturing components with functional use, where additive manufacturing makes more complex design possible in relation to traditional manufacturing methods. With the environmental problem that occurs in today’s world comes more extreme weather conditions, for example forest fires. With that as a basis, this project has explored the possibility of creating the sole of a shoe with a built-in cooling system, using additive manufacturing, for the purpose of extended work in an environment with a high temperature.

The requirements put on the sole was that in an environment of high temperature the sole should be able to help reduce temperature inside the shoe itself over the course of an eight-hour workday. Three primary models were analysed in terms of transient temperature as well as load and deformation with the help of CAD and FEM programs, where these three soles were compared to a sole without any form of cooling system. The results show that with the parameters of the project, a greater cooling effect is achieved in two of the three models, compared to a regular sole. Furthermore, there is the potential for continued development of similar models of soles with respect to specific demands in fields such as hiking.
