Improvement of Safety and Ergonomics in Industrial Safety Helmet
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
This report summarize the performed master thesis in Industrial Design Engineering, Product Design at Luleå University of Technology, LTU, 2015. The project has been conducted in cooperation with 3M Svenska AB, and their Personal Safety Division-Head & Face Products.The overall aim of the project was to improve the ergonomics and safety of one of their industrial safety helmets, G3000. Hence, there were two objectives. The first was to produce a prototype of a chinstrap with a new solution of the safety feature that shall release the chinstrap from the helmet according to the standard for industrial safety helmets EN397. The other was to generate proposals of general improvements of the current G3000 helmet.Before the project started a project plan was made in order to allocate available resources and form the project outline. Thus, the process contained three different phases within which there were several different activities and methods. In the first phase, information was gained in order to understand the context. Benchmarking of competitive and related products was carried out to get inspiration by mainly studying other industrial safety helmets and climbing helmets. Interviews and surveys were made to identify user needs and define current problem areas using industrial safety helmet and chinstrap. Thus, three general occurring problems were identified and served the base for the upcoming idea development phase. Firstly, the helmet was easily experienced as sweaty and warm according to the users. Moreover, the helmet was also experienced bulky and clunky as well as it tends to inhibit the field of vision. Findings from the pre-study also showed that few users actually uses chinstrap as the majority think of it as uncomfortable.On the basis of the information gathered, the next phase aimed to generate ideas of design solutions to meet user needs and requirements from 3M and according to the standard of industrial safety helmets EN397. Thus, creative methods such as brainstorming, analogical thinking and 6-3-5 methods were used. Two workshops were also arranged in order to produce ideas, one with students from LTU and another with employees at 3M.Generated ideas were then evaluated and concepts were formed using sketching, CAD and prototyping. Selection was made using the evaluation method pros and cons. The outcome of the project and thus the final result is a chinstrap prototype that can be attached to the helmet shell at three points with anchorages that also includes the release function. Likewise, there are three final sketches visualizing improvements of ergonomic and safety of the current helmet according the previous identified problems.
