Although there are numerous ergonomics assessment methods available for assessing safety, comfort, and performance of human-product interactions, there is a lack of comprehensive and widely available computational human-centered design framework that brings human factors principles into engineering design. In existing human-centered design approaches, computational assessment of human-product interaction is not explicitly considered as part of the early design phase, but rather it is addressed downstream in the design process through traditional human factors engineering strategies, often, includes physical prototyping and usability studies with extensive human-subject data collection. We hypothesize that digital human modeling can be utilized not only as an ergonomics evaluation tool but also as an engineering design methodology to embrace form and function during the early phases of the development. The digital human modeling approach has the potential to be a merger between the form and functionality aspects of product design by focusing on human needs, abilities, and limitations. This paper introduces a novel human-in-the-loop methodology which injects human factors engineering principles via digital human modeling into a computational design environment to assess the safety and performance of human-product interactions early in design.

Influence of a hybrid digital toolset on the creative behaviors of designers in early-stage design

JOURNAL OF COMPUTATIONAL design AND engineering 2019年第4期6卷 675-692页

The purpose of this research was to investigate how diversification of the repertoire of digital design techniques affects the creative behaviors of designers in the early design phases. The principal results of practice-based pilot experiments on the subject indicate three key properties of the hybrid digital tooling strategy. The strategy features intelligent human-machine integration, facilitating three different types of synergies between the designer and the digital media: human-dominated, machine-dominated, and a balanced human-machine collaboration. This strategy also boosts the cognitive behaviors of the designer by triggering divergent, transformative and convergent design activities and allowing for work on various abstraction levels. In addition, the strategy stimulates the explorative behaviors of the designer by encouraging the production of and interaction with a wide range of design representations, including physical and digital, dynamic and static objects. Thus, working with a broader range of digital modeling techniques can positively influence the creativity of designers in the early conception stages.

Current finite element (FE) approaches to model clothing on the human body in terms of personal protective equipment (PPE) are mainly bound to the discretization of the outer element layer of the human body model (HBM) and the given posture. Costs for PPE prototyping could be lowered drastically if an efficient and posture-independent clothing modeling method would be available, so that the effectiveness of PPE in terms of injury risk mitigation could be assessed in a donned configuration. In the present study, an FE modeling method was developed to map 2D planar clothing structures on arbitrary 3D human body contours. The method was successfully applied to the GHBMC M50-PS with a modular design based ballistic vest including all components, joints and fasteners. The 3D shaped clothing models in combination with arbitrary HBM allow to analyze the structural interaction of protective clothing with the human body in unforeseen dangerous situations. The presented method facilitates the building of full featured FE models of PPE in donned configurations.

The paper talks about the known concept of Multivariate anthropometry, a term explained in several other studies. The method consists of creating a family of manikins with a combination of more than one anthropometric variable to broaden, or to accommodate more users in a physical ergonomic analysis scenario. The paper explains how this method was adopted at a truck OEM and how it affects the design aspect of ergonomics. The paper also describes how the usage of such a method would be difficult to achieve before the advent of DHMs, CAD environments. Communicating this working method that is within reach of several industries is a history that is worth being aware of and sharing. Another section of the paper describes how different DHMs deal with this Multivariate method, and what possibilities are open for the users when they create their families in different software. The statistical concept of percentile is addressed in the paper, and presents it not as being a surpassed method, but rather as being one important variable of the Multivariate approach.

Numerous computational strategies were introduced in the past decades to integrate human aspects into the design process;perhaps, none provided a broader product design capacity equal to digital human modeling (DHM) research. The popularity of DHM usage in product development is increasing, and many companies take advantage of DHM in their virtual prototyping studies. However, DHM is usually interpreted as a post-conceptualization check gate methodology and is often applied to correct ergonomics assumptions. Although this approach provides some insight into product performance, designers often miss more widespread opportunities in terms of utilizing DHM as an early design stage design tool. This research presents our ongoing efforts in developing DHM-based early design computational human Factors engineering (HFE) support tools. We engage this reflection by summarizing two early design frameworks emerging from our recent work: (1) Prototyping Toolbox and (2) human Error and Functional Failure Reasoning (HEFFR). These frameworks are originated from the digital human-in-the-loop (DHIL) methodology. DHIL proposes a simulation-based computational design methodology that builds a bridge between existing Computer-Aided engineering (CAE) software packages and computational HFE tools to address safety, comfort, and performance-related issues early in design. Our primary focus in this paper is to demonstrate the frameworks emerging from our recent D-HIL research to promote better early design decision-making for human-centered product design.

Ergonomic design principles have been attempted to be included into product development and work system design over the times. The advancements in ergonomic evaluation have made it possible to integrate ergonomics into work system design. Virtual Ergonomics and digital human modeling (DHM) are fast emerging as enabling tools for ergonomic design, and analysis in digital manufacturing and product development. Ergonomic studies are done to analyze work-related musculoskeletal disorders on product design, workstations, and work systems by eliminating production prototypes and real-time evaluation of them, DHM shortens the cycle times of the product design and manufacturing processes. Anthropometry databases are used in product design and human ergonomics evaluation, and digital human modeling aids in ergonomics analysis from the beginning of the product and workstation design process. Conventional ergonomic assessment based on predetermined time standards and typical analytical approaches is discussed in the review article. To facilitate digital manikin modeling for human ergonomics analysis, various databases are integrated into the software. In this article, popular human ergonomics analysis software such as CATIA-DELMIA Jack and RAMSIS are studied for their merits and shortcomings in ergonomics design and analysis. © 2023, The Institution of Engineers (India).

Discomfort when using lower limb prostheses is still a major problem, leading to limited use of the prostheses and reduced mobility of the patient. The production of the socket is still more or less handcrafted, and modern Computer Aided engineering (CAE) technologies are rarely used due to the time-consuming and complex process. However, several researchers have already shown that the transfer of Computer-Aided design and Finite Element Modelling to the practical work of socket and liner design, a better fit socket can be obtained for improved comfort and safety. In Finite Element Modelling, static analysis has been predominant until now, although many previous researchers have suggested that dynamic computer simulations should be used to simulate the socket-limb interaction. This paper aims to present past efforts in Computer Aided design and simulations of prosthesis socket fit, and to present state-of-the-art technologies. Also presented are the capacity and limits of transient computer simulations. Furthermore, based on the paper review, we want to investigate to what extent this technology is used in everyday prosthetic work. As we can see, the technology for the data-driven design of lower limb prostheses is already available, and provides improved results in comparison to traditional methods. However, CAE and numerical simulations still present too high an effort to benefit ratio.

This paper presents research performed on behalf of Transport for London in the UK addressing the over representation of trucks involved in accidents with vulnerable road users where issues with driver vision are often cited as the main casual factors. A Direct Vision Standard for London and potentially for Europe has been developed that utilizes a volumetric assessment of field of view performance. This paper presents research into how to contextualize the somewhat abstract volumetric performance scores into real world metrics using digital human models. The research modelled 27 trucks currently available from major manufacturers and analyzed their volumetric performance. It also explored a supplementary process using digital human models define the minimum threshold of field of view performance. The current proposal utilizes thirteen human models, representing 5th %ile Italian females, positioned to front, left and right of the cab. The minimum standard was developed to ensure that no blind spot exists between the regulations for mirror coverage and the new Direct Vision Standard. The research is ongoing in line with the finalization of the standard at a European level.
