“…It could be that the short duration of the test did not allow to find the differentiation between comfort and discomfort. Dangal et al [ 11 ] found differences between effects of a seat on comfort and discomfort while sitting for 90 minutes. Therefore, further study is needed with longer durations to show the effect of time in this restricted space.…”

BACKGROUND: Staggered seats are a solution for the Flying-V aircraft, where the cabin’s longitudinal axis has a 26 degrees angle with respect to the direction of flight, to compensate for an otherwise oblique sitting position. However, little is known on acceptable pitches in this staggered configuration. OBJECTIVE: The goal of this research is to evaluate the comfort of different pitches for seats that are staggered relative to the cabin’s longitudinal axis. METHODS: Two rows of staggered seats are positioned at three different pitches (27, 29 and 31 inches). 53 participants were seated in each setup. For each, a questionnaire was completed including questions on comfort and discomfort, top view photos were taken to analyse postures and physical dimensions were recorded to define passengers’ space. RESULTS: Comfort as well as discomfort were significantly different for the three setups. The comfort at 27 inches was seen as unacceptably low. The 29 and 31-inch configurations showed to result in acceptable levels of comfort, comparable to higher-end seating layouts. There were very little complaints about space in lateral direction (elbow and seat width), showing the advantage of having your won armrest and shoulder space in the staggered configuration. Interesting was that at larger pitches more complaints were found for the seat characteristics, probably in the shorter pitch the other discomfort was overruling this. CONCLUSION: The 26-degree staggered configuration offers improvements in shoulder- and elbow-space. The results for the 29- and 31-inch are expected to allow enough design freedom for further exploration of such a configuration for the Flying-V cabin interior.

“…As in the automotive seat industry, comfort has been an important factor for passengers in choosing an airline and the aircraft for many years, and it makes sense to design a comfortable interior and seat to attract passengers. Some studies show that a seat pan design using spring-foam technology can be lighter and more comfortable than conventional foam cushion materials [60,65]. Comfort is established by six factors: anthropometry, climate, sound, vibration, illumination, and smell.…”

Furniture as a functional object must satisfy both artistic and scientific requirements. In particular, ergonomic factors are very important in furniture design in terms of human health and productivity. To make furniture designs at the ideal intersection of science and art, it is necessary to approach furniture design with a scientific systematic. Accordingly, this paper summarizes and analyzes the current state of biomechanics in ergonomic furniture design, covering an overview of the biomechanics utilized in different types of furniture design, biomechanical analysis, and testing methods. In the conclusion of the study, the literature analysis identifies the key topics and areas of future exploration regarding the use of biomechanics in ergonomic furniture design. The findings of the review indicate that (1) the primary studies on biomechanics used in furniture design concentrate on special furniture, such as wheelchairs and transportation vehicle seats, with minimal investigation performed on common furniture; (2) mechanical analysis, experimental testing, and computer-aided ergonomics represent the main techniques applied in furniture design biomechanics; (3) the reliability of biomechanics used in furniture design needs to be improved due to the lack of fundamental parameters of the muscles and skeleton of the human body; and (4) more attention should be paid to the use of biomechanics in the design of common furniture, such as household and office furniture, which affects people’s health and comfort. The scientific and rational application of biomechanics should be integrated into ergonomic furniture design to promote healthy living and enhance work efficiency.

“…Foam materials have been formulated from basic materials comprising polymers, ceramics and metals such as aluminum, copper, steel, titanium and even gold. This kind of material has been utilized to solve different engineering problems mainly in general structural optimization (Gibson and Ashby, 1997), ships design (Banhart et al, 1998), aerospace applications (Dangal et al, 2021;Marx et al, 2020) and automotive industry (Moon et al, 2019;Romero et al, 2021;Yavuz et al, 2016). Porous structures can be used in ballistics for military areas (Ahmadi et al, 2020;Kaboglu et al, 2018;Marx et al, 2019), shock absorbers and heat exchangers for vehicles (Chin et al, 2022;Fiedler et al, 2021;Kuruneru et al, 2020).…”

PurposeThe purpose of this article covers the design and manufacture of porous materials that can be used in different engineering applications by additive manufacturing.Design/methodology/approachThe most important design parameters of the porous materials are the cell structure and wall thickness. These two design criteria are difficult to control in porous materials produced by conventional production methods. In the study, two different wall thicknesses and four different pore diameters of the porous structure were determined as design parameters.FindingsA compression test was applied to the produced samples. Also, the densities of the produced samples were compared. As a result of the study, changes in mechanical properties were observed according to the cell wall thickness and pore size.Originality/valueThe originality of the study is that, unlike traditional porous structure production, the pore structure and cell wall thicknesses can be produced in desired dimensions. In addition, a closed pore structure was tried to be produced in the study. Studies in the literature generally have a tube-type pore structure.
