Aims
Project Consumer Products (IDE, IEM, ME)
After successfully finishing the project a student is able to:
  • Design and engineer a consumer product that fulfils the request of a client.
  • Select and set priorities in a plethora of relevant design aspects in the form of deliverables towards a client for a new and mass-producible product.
  • Integrate and employ knowledge from different fields of expertise (like marketing, styling, CAD/CAM, intellectual property, packaging, production, supply chains, research methodology, etc.)
  • Document a product and its development cycle such that selected priorities and design choices are underpinned and can be discussed easily with representatives from a diverse audience.
  • Present and communicate a product and development in a convincing and coherent way.
  • Concurrently pay attention to subject-matters and organizational aspects (project planning, reflection on intermediary results and project management).
  • Display interest and takes action to plug gaps in own knowledge by self-study, enquiry or experimentation.
  • Perform a patent study about a product concept or about components of the product design.

Specialization: Designing in plastics
After successfully finishing this specialization a student is able to:
  • take the relationship between product design, material selection, production process (injection molding) and mold design into account.
  • summarize the properties of the most important plastics.
  • take the influence of temperature, environment, ageing and use on the properties of plastics and polymers into account.
  • take into account the influence of the most important processing methods for rubber and plastics on the properties of product and material.
  • set up a list of demands for material selection for a specific product.
  • select a material based on a list of demands, and propose an adequate processing method.

Specialization: Mould design
After successfully finishing this specialization a student is able to:
  • take into account the relationship between product design, material selection, production process (injection molding) and mold design.
  • name the boundary conditions for product design based on the choice of injection molding as production process.
  • construct surface and solid geometries in a 3D CAD system of products with a double curvature and/or thin walls.
  • design an injection mould using a 3D mould model with the product geometry as starting point.

Specialization: Simulation of injection moulding
After successfully finishing this specialization a student is able to:
  • take into account the relationship between product design, material selection, production process (injection moulding) and mould design.
  • optimize the product design for the injection moulding process.
  • optimize the process settings to avoid products out of specification due to inclusions of air, weld seams and product deformations.
  • minimizing the cycle time of the injection moulding process (and thereby optimizing the cooling time of the product)
Academic skills 6
Additionally the student is able to:
  • works as a member of an interdisciplinary team and reflect on the consequences of interdisciplinarity on the team cooperation and performance
  • reflect on his / her own discipline and its unique contribution (added value) to the design process
Content
This is a part of module 6, ME 6 Product Design of the Bachelor Mechanical Engineering.. See here for the compete description of the module.

Content Project Consumer Products
The goal of Module 6 is to introduce students to the complexities involved in the development of consumer products. Students are confronted with a large variety of subjects that collectively play a role in a development trajectory that is representative and typical for a consumer product. As multiple disciplines play important roles in the development of consumer products, the entire development cycle - from portfolio analysis, via market research to the presentation of mock-ups and manufacturability - is relevant. Also questions related to priority, argumentation, reflection and project management play important roles.
To touch upon the ‘real’ complexities in product development, students participate in a development project with a factual problem formulation. This means that -each study year- a new problem is formulated in co-operation with a company (or organisation). The client (company) introduces the problem and reflects on the results at the end of the project. Where desired and possible, the company will also be involved during the project.
To emphasize the realistic setting, students collaborate in multi-disciplinary project groups resembling competing design bureaus. Each project group ideally consists of nine students, with an equal distribution over the IDE, IEM and ME backgrounds. The students, besides having a joint responsibility for the project results, also have their individual responsibilities in the other module components. As an independent member of the project group, each student has, therefore, the responsibility to effectively and efficiently allocate the time available. To obtain the best possible project results, each student needs to contribute from his/her own field of expertise. It, however, also implies that not each student can be involved all the time. Consequently, students need to carefully plan their activities in such a way that the substantive input and the organization of project activities are well attuned.
The ME students in the group will focus on the production cycle of the polymer product or component thereof. The three ME courses in this module are designed to support and build their knowledge about the production, properties and lifetime of the product. Each ME student in a project group will have a different specialization, taking care of particular aspects within the product development cycle, closely collaborating with the other ME specialists.
 
Specialization: Mould design
The mould in the injection moulding machine is the component that combines product, design and the production process. Multiple expertise are required to find the optimum route towards the best product, meanwhile balancing between costs, quality and the robustness of the production process. For these reasons, designing an injection moulding mould is often a complicated process. This complexity is increased even further by the geometrical limitations while designing a mould, the many features of the mould have to be combined in the smallest possible volume to reduce costs. Because of all the above, 3D modeling tools based on CAD protocols have become indispensable. This specialization treats the required design principles and 3D modeling skills.
 
Specialization: Designing in plastics
Multiple aspects are important when it comes to designing a proper polymer part. While designing, conditions of use need to be coupled to the corresponding mechanical properties, influencing the material of choice. In addition, the production method (and the material) needs to be considered. In this specialization, these steps are elaborated on. 
 
Specialization: Simulations of injection moulding
The main advantages of the injection molding process are found in the high freedom of design, rapid production rates, and low production costs relative to the number of parts. On the downside, the large of amount of available process settings complicate the process. Hence, it is a challenge to obtain minimum cycle times while maintaining the required properties of the part. The current state of the available computational modeling tools allows us to examine the influences altering design and/or process settings in order to estimate the final (mechanical) properties of the produced part.
 
Academic skills 6
The purpose of the Socratic Dialogue meetings is to help your group complete your project. This will be achieved, firstly, by showing you how to question yourselves and each other in order to discover what particular set of skills each member can contribute to the group. Secondly, we will show you ways to discover the specific strengths of your group as a whole, and challenge you to integrate these strengths into your product design. Finally, after your project has been completed, you will be asked to assess your group’s process, and to modify the standards for your group that you had previously identified.
