Preliminary Design

When starting a design project, first SIMUNES engineering team lists the design requirements for defining the problem, researching the requirements, creating concept models, conducting a feasibility assessment and completing the preliminary design.

During the research phase, it is of great importance for the engineer to obtain the necessary information, including possible problems, solutions, costs and market requirements, and to collect the desired data by conducting research in this direction. In the problem definition & design requirements analysis phase, all the design requirements of the project are defined until the end of the engineering design process.

This phase includes an assessment of the end user's needs, system features and functions. This study can be carried out together with the feasibility analysis and may include the planning of mechanical and aerodynamic test requirements.

A project's feasibility study supports the decision-making process by analysing and summarising the various alternatives or techniques for the project, narrowing the options to include only the most relevant scenarios. This phase allows the engineering team to start creating project schedules, planning resource requirements, determining whether the project is achievable and producing the design within a certain budget.

The next step is to identify the concept phase to evaluate possible solutions using cost management, risk assessment and conceptual design techniques. These concepts are defined in accordance with the requirements and conditions of the desired design. Design verification tools are used to detect weaknesses in the design. With the team work carried out by the design and analysis engineers together, this situation is evaluated and the necessary solution suggestions are determined.

Conceptual Design

Conceptual design is the first step in the multiphase process involved in creating a new product. Product cost and innovative design solutions are clarified at this stage. In this context, conceptual design is the most important stage of the engineering design process. In the conceptual design process of each project, there are basic principles to be considered, depending on the competencies of the project.

Conceptual design is even more important in original and innovative products. Because a design solution at this important stage; It directly affects quality, cost, time, creativity and innovation. In other words, the biggest contribution to the innovative aspect of the project is provided at this stage. For this reason, it is of paramount importance to include creative solution-finding techniques in the studies. The innovation process starts with producing creative ideas suitable for needs or problems.

In order to use innovation techniques in conceptual design, innovation must first be analysed. Innovation aims to commercialize a product or process with a high innovation aspect and achieve high added value. Here, it is very important to support the creativity level of the project with the commercial function.

Detail Design

The next step from the conceptual design is the detail design phase. In detail design, specifications and predictions are created while the design is finalized. In this step, which is ready for production, care is taken not to change the general lines of the design. Requests that have been changed or specified for the first time are evaluated and analysed.

By discussing how the analyses can be integrated into the concept, the changes to be made in the design are determined and corrected, and feedback is given to the user. It is known that detail design is the most important step in defining the costs of a project, as shown by practical and theoretical applications that have taken place over the years.

In detail design, it is ensured that the overall design plan meets the project objective. At the detailed design stage; The resulting design should be detailed to include the engineering data necessary for production. At this stage, information about the project, instructions, standards should be documented appropriately. It should be ensured that legal requirements such as desired or required safety standards in the design are met. The detailed design phase covers every information about the whole project, including business partner satisfaction and the functionality of the design.

Technical calculations and design form the basis of detailed design. At this stage, the parts are modelled and verified by making necessary examinations. All details of production and design should be defined in detail in this step. Here, the designer's task is to document and identify the necessary information regarding parts, assembly, materials and the project. After the drawings, models and assembly plan have been determined in detail, the next step is to verify the design.

Design Validation Studies

Verification of the design can be considered as checking that design provides the targeted competencies and obtaining compliance by the customer. ISO 9001:2015 form is a document that organizations use for design planning and verification, adapting it to their needs. More than one method can be used during the verification phase. In this step, if there is an alternative calculation method, some results can be obtained based on this method and the data can be compared. In another method, some results can be obtained by comparing the design with similar ones. Tests, experiments and reverse engineering methods can be used during verification. At this stage, it may be useful to review the documents, reports, proceedings and specifications created during the design process.

The general outlines of the planning at the design verification stage are mechanical design controls, controls of the technical drawings created, controls of the manufacturability and applicability of the design. At this verification stage, it is aimed to meet the required standards and customer satisfaction.

Technical Drawing

SIMUNES creates technical drawings of prototypes and ready-to-run products together with its expert design engineers, depending on customer requests. Great care is taken in the preparation of drawing letterheads, including line weights and font criteria. If there is an assembled structure in the design, the order of the fasteners is made by taking into account the assembly sequence and the production methodologies suitable for the assembly sequence.

Technical drawings of the parts to be produced are created by adding detailed notes of processes such as appropriate geometric tolerances, shape, position tolerances and surface roughness, coating and paint suitable for materials. Thus, technical drawings are prepared by showing all sufficient information to be used in the production processes of three-dimensional models.

Assembly Documentation

2D and 3D graphic contents are prepared by the SIMUNES engineering team in order to bring together, clearly explain, present and market the designed products. Documents created by SIMUNES contain all necessary and sufficient information to explain processes and procedures such as 3D engineering models, manufacturing assembly instructions in technical communications, product manuals, installation instructions, service manuals, training guides, marketing brochures and sales offer kits.

Thus, the comprehensibility of the projects is further improved and the user errors that may occur during installation are tried to be eliminated via the visualized details. While preparing the assembly documentation, studies are carried out within the scope of international standards and company standards.
