Reverse innovative design - an integrated product design methodology
Computer-aided Design, 2008
Today's product designer is being asked to develop high quality, innovative products at an ever increasing pace. To meet this need, an intensive search is underway for advanced design methodologies that facilitate the acquisition of design knowledge and creative ideas for later reuse. Additionally, designers are embracing a wide range of 3D digital design applications, such as 3D digitization, 3D CAD and CAID, reverse engineering (RE), CAE analysis and rapid prototyping (RP). In this paper, we propose a reverse engineering innovative design methodology called Reverse Innovative Design (RID). The RID methodology facilitates design and knowledge reuse by leveraging 3D digital design applications. The core of our RID methodology is the definition and construction of feature-based parametric solid models from scanned data. The solid model is constructed with feature data to allow for design modification and iteration. Such a construction is well suited for downstream analysis and rapid prototyping. In this paper, we will review the commercial availability and technological developments of some relevant 3D digital design applications. We will then introduce three RE modelling strategies: an autosurfacing strategy for organic shapes; a solid modelling strategy with feature recognition and surface fitting for analytical models; and a curve-based modelling strategy for accurate reverse modelling. Freeform shapes are appearing with more frequency in product development. Since their "natural" parameters are hard to define and extract, we propose construction of a feature skeleton based upon industrial or regional standards or by user interaction. Global and local product definition parameters are then linked to the feature skeleton. Design modification is performed by solving a constrained optimization problem. A RID platform has been developed and the main RE strategies and core algorithms have been integrated into SolidWorks as an add-in product called ScanTo3D. We will use this system to demonstrate our RID methodology on a collection of innovative consumer product design examples.
Research in Engineering Design, 2023
When a product variant offers functionality that is high in demand, firms may decide to leverage that design to enhance other variants in their product line. This can be achieved by extracting functions and their realisations from one product variant and integrating them into another variant, resulting in a third product variant that has a new combination of functions and physical features. This article introduces a systematic approach called the Adaptive Redesign Method (ARM) to support this function integration process. The ARM is based on a new product model called the Detailed Design Model (DDM). In comparison to existing approaches, the DDM allows the architecture of an existing product to be modelled on a sufficiently detailed level to identify geometric features and parts that realise particular operating functions of a product. This detailed information provides a basis for systematic determination of the redesign activities needed to derive a new variant design, down to the detailed level of adding, removing and integrating specific parts and features. The main benefit is to assist with planning the redesign process while ensuring nothing is overlooked, which might be especially useful if the task is to be divided among several designers or if designers are not fully familiar with the designs at hand. A secondary benefit is to show how this type of redesign process can be decomposed into systematic steps, which could potentially reveal opportunities for computer support. The new approach has been developed and tested through reverse engineering studies of consumer products, confirming its applicability.
Supporting Product Development Activities By Reverse Engineering Technique
2020
Several product design processes were proposed in the literature. Their implementations in curriculums, however, do not equip students with the range of skills needed for designing innovative products. To address this issue, the proper integration of reverse engineering in product development processes can have a significant advantage for pouring insightful knowledge into their associated hands-on activities. This work illustrates the integration of reverse engineering techniques into a widely used process in engineering education. In order to test its relevance, the results of it use by a class of engineering student is illustrated. This approach is thought to provide students with a more effective design process for the acquisition of both explicit and tacit knowledge of design.

The application of reverse engineering (RE), digital prototyping (DP), computer- aided design (CAD) and computer-aided manufacturing (CAM) is essential in devel- oping of the new products. This paper describes a methodology to obtain a new model, for an existent product using the techniques above-mentioned. With these techniques we will reduce the overall time of the design and manufacturing process. For
PHENIX: product history-based reverse engineering
Reverse engineering (RE) is an activity which consists in digitising a real part in order to create a CAD model. Today, a lot of references are centred on geometrical approaches based on transformations of the point cloud. The issued CAD models are generally 'frozen' or barely re-usable. Nevertheless, to support engineering changes in a new design process, the product should be represented with a parametric geometry. This paper suggests a knowledge-based approach in order to provide a product's parametric CAD model. A data model based on the extension of the core product model (CPM) is suggested and enables to manage multi-CAD models of the knowledge-based RE process.
DESIGN FOR ASSEMBLY TECHNIQUES IN REVERSE ENGINEERING AND REDESIGN
Design for Assembly (DFA) is the process by which a product is designed to be easily assembled. Such design simplifications are accomplished through reducing the number of operations required to assemble the product, improving the handling of each component, and/or modifying the required operations (insertion, joining, etc.). There exist several techniques for assessing the assemblability of a design through an analysis of these three aspects. However, there also exists a clearly defined need for evolving such techniques to indicate how a product should be redesigned with respect to customer needs and associated functionality. This paper presents three such straightforward evolutions, aimed at reducing the number of components in an assembly during redesign. The first technique is a component elimination procedure, the second technique is a component combination analysis, and the third technique establishes a logical approach for revealing more abstract component elimination or combination opportunities. These three DFA techniques are integrated within a reverse engineering and redesign methodology. They are then applied to a industrial design application, i.e., redesign of an auxiliary automobile visor. Results demonstrate definitive part count reduction, while maintaining and improving design functionality.
RE (reverse engineering) as necessary phase by rapid product development
Journal of Materials Processing Technology, 2006
The engineering design supported by CAD/CAE techniques allows optimising the product concept before manufacturing with assistance of CAM, in management for rapid product development and rapid set-up production in advance. For some product development processes reverse engineering (RE) allows to generate surface models by three-dimensional (3D)-scanning technique, and consequently this methodology permits to manufacture different parts (for cars, for household appliances) and tools (moulds, dies, press tools) in a short development period. The aim of this paper is to present a brief overview of RE as a necessary phase which provide benefits to the design and production processes in advance.
Reverse Engineering in Product Manufacturing
Journal of emerging technologies and innovative research, 2019
In the field of manufacturing and design industry, reverse engineering has proved to be beneficial for the growth and development of the mechanical industries. This technique has been generally accepted as an effective product design and development process technique. In standard computerized manufacturing system, the operating order normally begins with the concept of the product and finishes with various types of machine or CNC operations to turn raw material into finished product which is ready to enter in the market. Using some digitization methods, it is always necessary to replicate a CAD model of the actual component where the documents and drawings prepared by the designers are not accessible and are needed for review and modifications to create an enhanced product design. The essential steps involved in reverse engineering method include classification of geometric structures and associated surface depictions, segmentation & the surface fittings of the basic & free-forms model shape & the development of realistic CAD models. This paper discusses about the technique of reverse engineering and its implementation fields related to the advancement of product design. Redesign of the product and reverse engineering work would substantially minimize the costs and time required for manufacturing the physical components in the manufacturing industries.
