Konstruktion av fästanordning till baklykta

Sammanfattning: Volvo Construction Equipment (Volvo CE) is a part of Volvo Group and is among the biggest and leading manufacturers of construction equipment. The factory in Eskilstuna consists of approximately 2,100 employees. works with IT, sales, manufacturing transmissions, and axles. Volvo CE aims to increase the modularity across the company through its new modularity system called Common Architecture & Shared Technology (CAST). The ambition for CAST is that vehicles and construction equipment share components through standardization and modularization in the company. This bachelor thesis for innovation and product development aims to contribute to Volvos CAST-system for wheel loader. This study was conducted at Volvo electric facility for wheel loader and dumpers, at Volvo Technology Center in Eskilstuna. The purpose of the study is to develop a prototype of a module that could ease when Volvo changes tail light supplier. The module will be constructed out of sheet metal steel. Q1: How can the fastener be modularized to enable easier change of taillight supplier? The method for this study follows a traditional product development process with a detailed plan for the project through Gantt schedule, followed by different methods to generate concepts, choose concept, and construct a prototype. Unstructured interviews and semi-structured interviews were used to interview respondents at Volvo. The response was translated into customer needs and became the basis for the requirements specification. An external search for inspiration was made to find different ways to create a fastener. Chosen solution was the fastener that consisted of two parts. Concept generation resulted in 14 different concept models which were chosen through different screening method. Concept models were tested with consultation from relevant respondents at Volvo.The conclusion from this study showed difficulties to fulfill all customer needs when the fastener consists of many parts and small u-formed bends. There are risks that the surface treatment gets damaged and chipped from friction and vibration since the bottom- and top-plate is locked without any dampers. The tolerance for the fastener needs more work to ensure stability and make the fastener into a reliable product. Recommendation for future solutions is to integrate an easily modifiable fastener for the taillight into the construction of the wheel loader counterweight without affecting the counterweight’s function and aesthetics.
