The global megatrends of digitization and individualization substantially affect manufacturing enterprises. Assembly workers are exposed to increased process complexity resulting in physical and cognitive workload. Worker guidance systems (WGS) are used to overcome this challenge through output of information regarding what should be done, how it should be done and why it should be done. An unsolved scientific challenge in this context is efficient information supply of WGS. Information such as worker’s instruction texts, pictures or 3D representations are created by employees of the work preparation department and transferred to the WGS. Manual information supply is a time-consuming and complex process, which requires a high (non-value-adding) effort as well as comprehensive knowledge in handling 3D CAD modelling and software programming. This paper presents a novel approach to reduce the required manual effort in information supply process. A knowledge-based model is proposed that enables an automated information supply of WGS in smart assembly environment by means of algorithms and self-learning expert systems, which pursues a holistic and consistent approach without media breaks. The automated approach assists employees of work preparation department, which means they can concentrate on their essential core competencies instead of being busy, for example, creating assembly plans, instruction texts or pictures for individual WGS. Finally, the technical implementation as a software-based proof-of-concept demonstrator and sub-sequent integration into the IT environment of TU Wien Pilot Factory Industry 4.0 is outlined.

Worker information systems provide the right information at the right time in a lean way. In this paper, the need for an integrated feedback system with formalised text parts is exposed. To meet the disadvantages of a lack of feedback, two important points are identified: involving of workers and guaranteeing a high information quality. Several approaches show that workers have to be included into an early stage of product development process to improve product details and especially assembly scenarios. Also, workers get an idea of their contribution to a zero-waste production. If more information is created, the quality gets more important. It is explained what quality criteria should be considered. Technical realisations for a feedback system close this paper.

“…Such difficulties can lead to serious production problems, including ergonomic issues for operators [27], work accidents [28], and compromised product quality, prompting companies to invest significant resources in redesign efforts. Some authors [29] did extensive research on the dynamic stress and post-breakage behavior of a prestressing strand and proposed a finite element model that is generally useful to study the global response of the strand, along with many localized phenomena that have a strong influence on their performance, but which are difficult to capture either experimentally or through closed-form analytical models [30,31]. However, investigations into certain behaviors, such as cable breakage, require a relatively large or fullscale model to adequately develop contact and friction conditions [32].…”

In the automotive industry, arranging wire harnesses in assembly plants requires manual work. The stiffness of the high-voltage cable implies that personnel applies sufficient force on the cable to achieve a proper installation. Sometimes, the applied force is not strong enough; thus, the cable is not properly installed, or the personnel gets injured, raising ergonomic concerns that need attention. The challenges arise from the intrinsic cable characteristics such as diameter, copper type, cable strand quantity, first-layer insulator, cable insulator glue, and protective covering. The primary objective of this research is to examine how various factors, such as cable length and protective covering, impact the mechanical properties that influence the assembly of high-voltage cables. The methodology proposed consisted of characterizing the mechanical properties of the high-voltage cables in a cantilever beam test to measure deflection in response to an applied force. The measured properties were contrasted through a Finite Element Analysis of the high-voltage cable. The results validated the initial hypothesis, revealing two key findings. Firstly, the stiffness of cables varies with increasing length. Secondly, cables with tape exhibit greater stiffness than those with conduit and cables without covering, as detailed in the results section. In conclusion, extending cables without attachment points is recommended until the interfaces and environment permit. Furthermore, minimizing tape for cable protection while exploring alternative safeguards can enhance stiffness and facilitate an ergonomic installation assembly under favorable conditions. This study contributes valuable insights for optimizing high-voltage cable installation processes in assembly plants, addressing stiffness concerns through informed choices and design considerations.
