This paper presents the design process of a novel general-purpose electric vehicle chassis as agriculture payload carrier platform to perform agricultural tasks: detection, guidance, mapping, and action. This design applied a human-centered design frameworks and processes: Kumar's seven modes of the design innovation process, and the three lenses of human-centered design by IDEO. After approach from three design-project perspectives mapping, a universal electric-powered multiwheel independent drive and independent steering robotic vehicle platform is designed for agricultural application. A real size prototype has been built to prove the design.

This paper presents a design process of a novel electric wheelchair controller to enable a dual control access for both the users in the wheelchair and their caregivers. This design applied human-centered design frameworks, processes, and tools: Kumar's seven modes of the design innovation process and IDEO, Palo Alto, CA, design method cards. After such design process, a design of dual control access controller of an electric wheelchair is established. A real-size prototype has been built to prove the design concept; and further, the method of control switching between people in and behind the wheelchair has been optimized with the established prototype.

Load Conditions

The development of an electric vehicle chassis is one step in the design process of a vehicle, especially for crossover vehicles that are being designed. The chassis design of the vehicle must have a chassis that is solid and can sustain all the loads that occur on the chassis, such as passenger loads, electric motors and so on. In the chassis design process, stress analysis is needed to verify the strength of the chassis if the loads that are applied. Stress analysis begins with making an initial model of an existing chassis using CAD then stress analysis using FEA Solidworks software. Stress analysis includes static and crash load. The results of the analysis under static load conditions obtained a maximum stress that occurs at 206 MPa, a factor of safety = 1.69, and a deflection of 0.4 mm where the chassis deflection due to bending is less than 1 mm. Keywords: chassis, EV, strength simulation, FEA.

BACKGROUND Design-based approaches to healthcare strive to support the development of innovative, effective and person-centered solutions for healthcare. Although their use is increasing, there is no systematic overview describing the details of human centered design (HCD) methods in health innovations. OBJECTIVE This study aims to provide an overview of human centered design approaches applied for the development of health innovations, with the aim of assisting healthcare workers and design researchers in selecting suitable methods for participatory and human centered design processes. METHODS We performed electronic searches in Pubmed, CINHAL, Embase, Cochrane Library, Web of Science, PsycInfo and Sociological Abstracts (2000 – 2020) using search terms related to “human-centered design”, “design thinking”(DT) and “user-centered design”(UCD). Abstracts and full-text articles were screened by two reviewers independently based on predefined inclusion criteria. Data extraction focussed on (a) the methodology employed throughout the research process, (b) the choice of methods in different phases of the innovation cycle and (c) the level of engagement of end-users. RESULTS A wide variation of design-based practices are increasingly applied in health research. Design-based approaches are applied in health research in combination with traditional qualitative and quantitative approaches. All included studies structured the innovation process using a variation of the following phases: understand – define – generate ideas – test. HCD/DT-based research primarily targeted understanding the context and defining the problem whereas UCD-based work focused mainly on the direct generation of solutions. CONCLUSIONS Design-based researchers should tailor their choice of design methods according to their primary focus; problem identification or solution development. Design techniques are challenging to evaluate with traditional biomedical research methods, limiting the opportunity for standardized assessment. Future research on HCD practices should focus on the development of specific standards, transdisciplinary evaluation methods, and guidelines for stakeholder engagement.

Users With Special Needs

Human-Centered Design focuses on the analysis, specification and involvement of a product's end users as driving elements in the design process. The primary research objective of the case-study presented in this paper is to illustrate that it is essential to include users with special needs into all major steps of designing a web-portal that provides services to these special users. But how can this be accomplished in the case of users with special cognitive and affective needs? Would the “classical” Human-Centered Design Process (HCD) be sufficient or would it need to be adapted and complemented with special procedures and tools? In this paper the design team shares the strategies they adopted and the experiences they gained by including users with dyslexia in the design of the LITERACY Web-Portal. Besides providing insight into the special effort and steps needed to adapt HCD for users with special needs, the paper encourages application designers to include end-users even though - or particularly because - they have needs that are special and critical for the adoption of the product.
