Human Capability-Sensitive Design Rules for Products using Inclusive Design Principles
MetadataShow full item record
Several design methodologies have been developed that seek to address the diverse needs of disabled users. This work reviews three such methodologies: universal design, design for all, and inclusive design. The core ideas to these methodologies are researched and explained. This work then describes a multitude of state of the art design techniques that utilize these design methodologies, and analyzes two such techniques that are readily applicable in the abstracted, functionally focused design methods that engineers commonly use. Previous research in inclusive and universal design has led to several sets of inclusive design rules and guidelines. These guidelines suggest modifications to products, environments, and services that could lead to more inclusive redesigns. It would be very beneficial to apply these design guidelines in the initial concept generation process to develop inclusive products; as current accessible design methods rely on expensive specialized modifications to typical products. Preliminary research into these inclusive design rules, and their underlying design representation scheme, has shown that these rules and methods are useful in designing inclusive architectural products. Here, architectural products are defined as products and environments for which the space around the product is important for inclusive design. This work seeks to supplement previous research, and analyze the effectiveness of these design rules when applied to consumer products (i.e. products for which product usability is very important to inclusive design). This work analyzes sets of inclusive design rules; first by observation, followed by an in-depth case study testing each design rule on a product that was originally designed for users without disabilities. These case studies analyze how inclusive design rules affect products, and what modifications these inclusive design rules lead to. We then study potential users’ and experienced designers’ opinions regarding the inclusivity of these products in order to gain insight on the effectiveness of the related design rule. The design rules are further analyzed in a second validation study. This validation study tasks participants with redesigning typical products using the given design rules. We analyze how the participants apply the design rules, and what effects they have on product inclusivity.

For the purpose of maintenance requirements or for some applications in the chemical industry (for instance chlorine) the centrifugal compressor must be designed with a horizontally (axially) split casing. Beyond the decision about the type of manufacturing (cast or welded) or about the material selection one of the utmost issues regarding the design of the compressor lies in the leak tightness of the flanges. The design of the compressor casing needs detailed checking for tightness. In order to ensure a proper design with respect to integrity of stress and tightness under test and operating conditions several FE Analyses and resulting criteria have been developed by the OEMs. Furthermore in order to demonstrate the leak tightness the casing is subjected to a hydrostatic test prior to the assembly of the inner parts and rotor. According the API specification a hydrostatic pressure of at least 1.5 times maximum design pressure is applied. This standard procedure is usually considered to be sufficient for demonstrating the casing integrity, the tightness in operation and to check the accuracy of the FE analysis. However some applications require the use of several sections (consisting of some stages) inside one casing. According to the stage configuration hot and cold casing sections might be close to each other. In operation the compressor casing is subjected not only to pressure but also to thermal loading. These potential high temperature gradients can considerably influence the compressor behaviour regarding its tightness. The conventional hydrostatic test can even be less critical than at some particular operating conditions of the compressor on site. This paper describes some experiences of the author’s company with this type of compressors and the performed calculations. Different configurations are analysed and compared between each others. The paper shows the steps for the optimization of casings in order to develop an appropriate split line flange design supported by FE calculations. Some examples of different casing concepts are shown and discussed. At last the paper highlights some decisive issues which influence the tightness of compressor like: - Design of inner casing - Arrangement of sections - Geometry of flange - Design and arrangement of bolts.
