Oral ingestion is the predominant pathway of metal(loid)s exposure. In this study, the health risks of typical metal(loid)s (including Mn, As, Cr, Cd, and Pb) via multi-source, oral pathways for children aged 3–12 years, living in an area of China dominated by the electronic manufacturing industry, were studied based on the field sampling of duplicated diet, soil, and drinking water. Child-specific ingestion parameters were measured (except the soil ingestion rates, which were from a previous study of the same population), and a Monte Carlo method was applied to determine the uncertainty of the risk assessment. It was observed that children living in such environments were at risk of metal(loid)s exposure, with the accumulative carcinogenic risk exceeding the maximum acceptable level. Food intake was identified to be the primary exposure pathway. Moreover, Pb and Cr were the major risk elements to local children’s health. Compared with primary school students, kindergarten children experienced a higher risk. This study highlights that high attention should be paid to children living in suburban areas dominated by the electronic manufacturing industry, and that priority should be given to studies on metal(loid)s exposure deriving from different types of food and their corresponding bioavailability, in order to further discern the precise risk sources to protect children’s health.

Purpose – This paper aims to design a novel jaw gripper with human-sized anthropomorphic features to be suitable for precise in-hand posture transitions, such as twisting and re-positioning. The growing demand from traditional high-mix low-volume and new massive customized manufacturing industry requires the robot with configurability and flexibility. In the electronic manufacturing industry particularly, the design of the robotic hand with sufficient dexterity and configuration is important for the robot to accomplish the assembly task reliably and robustly. It is important for the robot to be able to grasp and manipulate a large number of assembly parts or tools. Design/methodology/approach – In this research, a novel jaw-like gripper with human-sized anthropomorphic features is designed for online in-hand precise positioning and twisting. It retains the simplicity feature of traditional industrial grippers and dexterity features of dexterous robotic hands. Findings – The gripper is able to apply suitable gripping force on assembly parts and performs reliable twisting movement within limited time to meet the industrial requirements. Manipulating several cylindrical assembly parts by robot, as an experimental case in this paper, is studied to evaluate its performance. The effectiveness of proposed gripper design and mechanical analysis is proved by the simulation and experimental results. Originality/value – The main originality of this research is that a novel jaw gripper with human-sized anthropomorphic features is designed to be suitable for precise in-hand posture transitions, such as twisting and re-positioning. With this gripper, the robotic system will be sufficiently flexible to deal with various assembly tasks.

Green Product Design

Abstract In the industrial society, the concept of green product research is becoming prevalent in many manufacturing industries. The green technology is implemented to develop an environmentally green product that brought attention to a growing technological field as it attains sustainable growth in a market. The green process includes logistics, manufacturing, and product design to reach a high level of sustainability. The utilization of green technologies in manufacturing industries reduces the major effect of industrial outcomes on environment. The product manufactured in the electronic industries is rapidly utilized by more population. This paper deals with the research issue faced during product manufacturing in electronic industries. Initially, the issues encountered during product development are air pollution, solid waste, and water pollution. The product is enriched with the characteristic features such as an increase in efficiency, reduction in toxic content, and must be eco-friendly. The developed green product should satisfy environmental standards. Environmental Conscious Manufacturing (ECM) accountability to satisfy the government rules and regulations for product development in the manufacturing industry and also deals with the customer’s expectation. The eco-friendly product includes eco-design, recycling, clean production, low cost, and reclamation of products. The eco-design is responsible for improving the environmental outcomes and also reliable for a reduction in long-term cost. The green product design and manufacturing focus mainly on energy conservation and the development of a product with less wastage. The research on green product manufacturing is mainly to save the environment by reducing carbon foot print and to make the product in less cost. The main consequence faced during the development of the green product is destroying the environment by utilizing natural resources. Thus, in this paper, the issues faced during the green product design and manufacturing of the electronic manufacturing industry are discussed.
