DISEGNO TECNICO INDUSTRIALE A - L

Academic Year 2026/2027 - Teacher: GAETANO SEQUENZIA

Expected Learning Outcomes

The course aims to provide the student with the concepts of graphic communication and industrial technical design, so that the same is able to represent, even through the freehand sketch and to interpret, through the reading of drawings, individual components and assembled of machines, identifying their technological and functional shapes and characteristics. The design should never be an end in itself, but must provide a clear and unambiguous representation of the designer's idea, allowing the realization and subsequent testing. The student must also acquire a first knowledge of the standardized functional components of the machines and the design procedures. The study of the insertion of technical documentation into the product life cycle is a characteristic element of the course. Finally, the basic elements of Computer Graphics and solid modeling will be illustrated, as they are the modern and current alternative to the classical tools of manual design. The objectives set by the course through the planned didactic activities are included in the training project of the CdS and will allow the student to acquire a design methodology necessary for the industrial engineer.

Dublin description

With reference to the objective of the Degree Programme, namely to train students in the field of industrial engineering, the contribution of the course is reflected in the acquisition of the knowledge and skills summarised below.

Knowledge and understanding

Successful completion of the course examination implies that the student has acquired:

  • knowledge of the theoretical and practical aspects and of the main design methodologies covered by the disciplines included in the degree programme;

  • the ability to understand problems, including highly complex ones, related to the design and implementation of complex mechanical, electrical, and mechatronic systems, as well as systems and plants for the production, transmission, and utilisation of energy;

  • knowledge of measurement methodologies for mechanical, thermal, and electrical quantities, as well as signal processing techniques.

Applying knowledge and understanding

  • ability to read and interpret mechanical drawings and diagrams.

Course Structure

The course consists of lectures, during which students are frequently required to participate actively. Practical exercises are also included, with the aim of enabling students to acquire the skills necessary for their training as industrial designers. All activities are fully consistent with the educational objectives of the course. Should it become necessary to deliver the course in a blended or distance-learning format, the appropriate measures will be implemented to ensure that the planned programme, as outlined in the syllabus, is fully delivered.

Learning Assessment

Learning Assessment Procedures

The oral examination may be taken on all the dates scheduled in the examination calendar for the graphic assignments and on any subsequent dates agreed upon with the students during the same graphic examinations.

Online registration is required to take the graphic examination. Students who are admitted following the in-course assessments must register online for the first examination date scheduled in the examination calendar.

The oral examination is not compulsory. Students who do not wish to take it may request that the final assessment be based on the course assignments and the graphic examination or in-course assessment. In this case, the grade cannot exceed 26/30 (twenty-six out of thirty). Students admitted conditionally are required to take the oral examination.

The final grade is calculated as the weighted average of the grades awarded for the course assignments, the graphic examination or in-course assessment, and, when taken, the oral examination.

During the oral examination, the assessment focuses on the relevance of the student's answers to the questions asked, the ability to provide a critical explanation of the proposed topic and establish connections with other relevant topics, and the appropriate use of technical terminology.

The assessment of learning outcomes may also be conducted remotely, should circumstances require it.

To ensure equal opportunities and in compliance with current legislation, students registered with CInAP may agree with the instructor on appropriate compensatory and/or exemption measures, based on the educational objectives and their specific needs. Students may also contact the CInAP coordinator(s) at DIEEI, Prof. Antonella Di Stefano and Prof. Arturo Pagano (https://www.cinap.unict.it/content/referenti).
