    This investigation analyses spotlight components to reduce the necessary amount and explore the potential to enhance the sustainable design. The DFMA and Sustainability design considerations for manufacturing assemblies were used and incorporated in this work. DFMA outcome displays that components were reduced while the LCA showed that weight, carbon footprint, acidification of the air, water eutrophication and overall energy consumption were reduced. This new approach is essential for demonstrating the efficiency of both tools used to reduce the cost of spotlight manufacture and enhance the sustainable aspects of product design.

    Design is the first step in any manufacturing process where the most crucial decisions are made which affect the product's ultimate cost. The researchers used DFMA method in this study to redesign and improve a joystick in order to achieve the goal to decrease the number of parts, handling and insertion time, and improve the design efficiency for a joystick. The main emphasis in this research has been on the design stage of a product development, with a view to accomplishing an optimal design approach for current product.DFMA principles have been used to develop new design ideas and the final design will be evaluate and compared to the current design. In result, the assembly time for redesign then increased by 21 % with a decrease in the assembly time from 294.2s to 232.44s and an improvement in design efficiency by 26.5 % from 20.4 % to 25.8 %.

    This paper presents an analysis of the mechanism of Belt-Pulley Driven Spray Plunger Pump. Belts and pulleys are used to transfer kinetic energy from the internal combustion (IC) engine to operate the pump. Combination of pulley and belts was used to transfer motion between each other simply without the need for meshed toothed gearing. The principal remains the same that there is a driver (powered) and driven (free). The benefit from application of belts which are mostly made of synthetic fibres is that no lubrication is necessary compared to chains. The analysis is focused on power transmitted from IC engine to plunger pump (design power) considering service factor as well as determining total number of belts to be used in the system with refer to FENNER Friction Belt Range Brochure Technical Docs.

    Design for assembly (DFA) analysis of old bicycle tire inflator
    This Paper is studied on the assembly problem of old bicycle tire inflator in the early stage of product design. During producing a product, the most important decisions are the final cost of the product. The approach based on Boothroyd Dewhurst methods has been implemented in this study to provide a quantitative measure called the design efficiency based on an analysis of a product. The main focuses of this research are to analyze the current design efficiency of old bicycle tire inflator and improved design efficiency. The product was design by using UNIGRAPHIC NX. The components and manufacturing of the old bicycle tire inflator were undergone alteration with the design for assembly (DFA) and redesigned methods.

    For this project, it is focused on redesign the original product and analysis of the product, which is the Speedy Chopper. The Speedy Chopper was inverted in the year 2015. The chopper is primarily used to mincing, mixing, whipping and prepare food for cooking purposes. Firstly, the objective of this project is same as the original product which is to make a tool that can chop food and vegetables, user-friendly operating, to save time when cutting the food and to reduce the usage of electricity. As a redesign, the original product is on the mechanism of the product where the original product is using the string that needs to pull several times to chop the input in the speedy chopper. So, the new design is using a rotating handle mechanism, and it is reducing the quantity of the part from the original product. Besides, engineering analysis will be conducted such as the product analysis, Failure Modes and Effects Analysis (FMEA), sustainability of the product and cost analysis before and after improvement of the product.

    Analysis of onion peeler machine using ansys simulation analysis
    Onion is the important cooking ingredients in the world of a cook. The current method to peel an onion is by a traditional method. There are have many effects when using a traditional method such as used by a hand and knife. By using this traditional method, the probability of injured such as sore eyes and hand pain are too high. Beside that, the process also takes a long time if the user needs to peel in the large quantities. The development of onion peeling machine needs to achieve the objective such as increasing the safety, save time and energy of human. The method of use in this project in fabricating this machine is by analysing the source of information data and apply its knowledge in fabricating the onion peeling machine. The method of design is generated with followed the engineering design guided. The final design selection of machine transforms into a 3D drawing using CATIA software. And then, 3D CAD data are analyses using ANSYS CFX simulation software to analyses the flow analysis of the part design. From this result, it will be considered whether it is necessary to make improvements on the machine design to improve the capabilities and effectiveness.

    Development of sustainable lightweight heat insulation panel from elastomeric and polymeric waste
    The project present about development lightweight sustainable heat insulation panel from waste material. Scrap tyres and plastic waste was used for this purpose. The fabrication process started with scrap tyres is being cut and blends into smaller pieces. Then, the pieces of the material of rubber from scrap tyres are mixed together with the plastic waste material polyethylene at different composition. The mixture of the materials is pressed together using hydraulic press machine and heat are applied to melt the material in order to create the panel by using the mould. There are few tests that are conducted to the panel to find out its weight, volume and density. In order to determine the most suitable sample among the sample, a test is carried out to each sample. This test involved the black box or wooden box and the container by using the thermocouple and probes to measure the temperature. From the both test using black box and the container, the most suitable sample that excellent in insulating the heat is the sample with the bigger composition of rubber which are sample with 95% of rubber and 5% of polyethylene polymer.

    This study focuses on evaluating a new alarm clock components and function to reduce the necessary quantities and to determine the potential to enhance sustainable design. The project aims to create a new alarm clock to enhance or improvise the alarm clock. To evaluate the built component, the CAD programme is used to create the new alarm clock and then transferred to FEA. The research will lead to understanding the use of CAD tools for the design and study of alarm clock enhancement by carrying out the project. This new approach shows that the tools that are to be used to reduce the cost of creating a new alarm clock and to enhance the environmental aspects of product design are successful.

    This study aims to analyse the components of the hairdryer to 1ecogniz the quantities or improvements in the features of the components involved, and it is necessary to study possible sustainable design improvements. Thus, it is implementing Design for Manufacturing (DFMA) and Life Cycle Analysis (LCA) approach to assist sustainability analysis. The results from a product survey of consumers found that 75% of consumers are from women while the rest are men who use hair dryers. Therefore, people in the 18-30 years old prefer to use the hairdryer when while 18.8% of users often keep the hair dryer on the makeup table and 12.5% of users keep the makeup drawer to look neat. While the results of sustainability study on hair dryer products have found that before analysis using PP Copolymer material there was a good impact on the product analysis in terms of Material Unit Cost of 2.80 USD / kg compared to previous use of ABS material of 2.90 USD / kg. While in terms of Material Financial Impact from the use of PP Copolymer there was a decrease of 0.20 USD compared to material abs usage of 1752.00 USD. In terms of weight the hairdryer has also experienced a weight reduction of 70.05 g to 60.04 g. But in terms of duration of use still the same period of the application for a year and also in term transportation still remain the same as truck distance 1600 km. The surface area of the product also decreased from 76268.30 mm2 to 74199.49 mm2. The methods used for hair dryer production are finite element analysis and sustainability analysis..
