This paper presents a conceptual product design method that considers the carbon emission factors of mechanical and electrical products, with the purpose of considering low carbon issues before designing products. Based on a comprehensive analysis of conventional product design procedures, the study extracts design information related to greenhouse gas emissions, itemizes and quantifies the information, and ultimately uncovers the relationship among carbon emissions, function and cost of newly designed products. This paper explains the proposed concepts of carbon efficiency and carbon factor, and combined them with the product design process to present a low-carbon design process of mechanical and electrical products. Furthermore, this paper presents a low-carbon design method of mechanical and electrical products, drawing on the product family design idea, with the GHG efficiency and cost constrained. The potential value of the method is demonstrated in a case study of a tomato picking robot.

“…In the paper, the fixed shape of the structure is used, and the individual parts are fixed to each other (by welding). A similar approach is also used in [39]. A beam element type could also be used to simulate the behavior of a structure created from a set of components (based on Merkur ® ).…”

Optimization of a Truss Structure Used to Design of the Manipulator Arm from a Set of Components

The design of a manipulator arm, which is built from a construction kit, is presented in this article. The procedure is based on the results of the discrete optimization of a truss structure and its application to a simple component system (assuming a predefined shape and material of components). A genetic algorithm is used to optimize the truss structure, and the results of the solution are verified on a simple task used in literature (the code was written in the Python language). The construction kit was inspired by Merkur®, and the article proposes several components with different shapes and materials. The construction kit and the optimization of the truss structure were used to design the manipulator arm. The truss topology has been predefined with respect to the construction set. The finite element method (software ANSYS®) was used to analyze the components (shell elements) and truss structures (linear analysis, buckling analysis, etc.). To validate the presented approach, the arm designed by topological optimization was used. The comparison shows that the use of components may be an alternative to topology optimization and additive manufacturing. The next step will be the modification of the presented method in order to minimize the differences between the simplified task used for optimization (truss structure-rod element) and the simulation composed of components (components assembly-shell element).
