Basic Ability

Contemporary product designers seek to create products that are not only robust for the current marketplace but also flexible for future changes, adaptations, and evolutions. This type of product flexibility is distinctive from mass customization, product architecture of singular products, and product families. The intent is to design products that intrinsically enable future changes even though such changes may not be known or planned in the current product offering. To accommodate product flexibility of this type, research advancements are needed in terms of fundamental design principles and evaluation methods for predicting and improving the flexibility of a product. This paper presents advancements in both areas. We first present the systematic enhancement of a flexibility assessment tool referred to as CMEA, Change Modes and Effects Analysis. CMEA provides the basic ability to assess the flexibility of a product, with analogous features to the well-known Failure Modes and Effects Analysis. Our enhancements extend the method to provide for intuitive and more repeatable measures of flexibility. We then use the enhanced CMEA to investigate a variety of consumer products with the goal of inductively deriving product flexibility principles. Concrete applications are shown for these principles from the domain of power yard tools, such as hedge trimmers, weed trimmers, and leaf blowers. Also, the applications are used to demonstrate the value of the CMEA enhancements.

For consumer products, early design stages are often concerned with the product’s industrial design, with primary focus on the consumer’s product experience. At this stage, aspects such as manufacturability and robustness are often not thoroughly taken into account. Industrial design concepts not properly suited for manufacture, assembly and process variability can result in final products in which the appearance intent is not satisfactorily realized. This can have a negative impact on the customer’s product quality perception. If such problems are discovered late in the product development process, late design changes and increased project costs may follow. The main difficulty in evaluating perceived quality aspects during industrial design is that the product is still under development. It is not mature enough to enable prediction of the prerequisites for achieving high manufacturing quality. In this paper, we suggest that concepts instead could be evaluated as far as the intrinsic tendency of the product appearance to support manufacturing variation and other noise factors. This is addressed through the concept of visual robustness: the ability of a product’s visual appearance to stimulate the same product experience despite variety in its visual design properties. Here, a method is suggested based on the Failure Modes and Effects Analysis (FMEA). The method follows a structured procedure for addressing appearance issues.

Common Platform

Product family design is a well recognized method to address the demands of mass customization. A potential drawback of product families is that the performance of individual members are reduced due to the constraints added by the common platform, i.e. parts and components need to be shared by other family members. This paper presents a formal mathematical framework where the product family design problem is stated as an optimization problem and where optimization is used to find an optimal product family. The object of study is kinematics design of a family of industrial robots. The robot is a serial manipulator where different robots share arms from a common platform. The objective is to show the trade-off between the size of the common platform and the kinematics performance of the robot.

Recent manufacturers have been utilizing product families to diversify and enhance the product performance by simultaneously designing multiple products under commonalization and standardization. Design information of product architecture and family is inevitably more complicated and numerous than that of a single product. Thus, more sophisticated computer-based support system is required for product architecture and family design. This paper proposes a knowledge model for a computer-based system to support reflective process of designing product architecture and product family. This research focuses on three problems which should be overcome when product family are modeled in the computer system; design repository without data redundancy and incorrectness, knowledge acquisition without forcing the additional effort on the designer, and integration of prescriptive models to support early stages of the design process. An ontology that is a foundation of a knowledge model is defined to resolve these problems. An example of designing an air conditioner product family is shown to demonstrate the capability of the system.

AbstractManufacturing companies nowadays face growing numbers of heterogeneous customer requirements. Due to that, internal and external complexity lead to an increase in the associated costs. Especially companies with a high Engineer-to-Order business are strongly affected. To reduce external and internal complexity, Starting Solutions are a suitable way to do that. Starting Solutions require on the one hand the evaluation of product flexibility, on the other hand the evaluation of customer requirements. These two requirements are compared to each other and Starting Solutions are thereby derived.

Headlamp assembly entailed a complex assembly process and error in assembled can result in technical problem and higher reject rate at the end of the assembly process. A study has been conducted, in one of the automotive headlamp assembly in Malaysia, where there are numerous defect detected during the assembly process, such as metal spacing missing, wrong model housing, wrong sticker affix, wrong orientation with a total of 80% defects detected. Currently the headlamps are assembled with no dimensional control, results in high physical nonconformity product. The main objective of this project is to identify potential failure in headlamp assembly process. The approach used was risk assessment tool which is Process Failure Mode and Effect. This work also developed the corrective action plan for accurate ranking of Failure Modes by Risk Priority Number-based method and implement it to the process assembly. The result showed that there was increased of 5% in preventive action and 4% increment of the detection action

Abstract Mass customization is becoming an important agenda in industry and academia alike. This paper deals with mass customization from a product development perspective. A framework of design for mass customization (DFMC) by developing product family architecture (PFA) is presented. To deal with tradeoffs between diversity of customer requirements and reusability of design and process capabilities, DFMC advocates shifting product development from designing individual products to designing product families. As the core of DFMC, the concept of PFA is developed to assist different functional departments within a manufacturing enterprise to work together cohesively. A PFA describes variety and product families and performs as a generic product platform for product differentiation in which individual customer requirements can be satisfied through systematic decisions of developing product variants. Based on such a PFA, the DFMC framework provides a unifying integration platform for synchronizing market positioning, soliciting customer requirements, increasing reusability, and enhancing manufacturing scale of economy across the entire product realization process.

This article focuses on the missing link in mass customization. Mass customization has not really caught on yet because of a missing link—knowing how to actually design and build mass-customized products. The solution is concurrently engineering product families and flexible processes so any product variation within a family can be built on-demand using common parts that are always available. Accomplishing this requires some new and different strategies: production strategy, supply chain strategy, design strategy, and marketing strategy. The production strategy aims to build any variation in a product family on demand economically, which requires versatile flexible processes without expensive setup charges or delays. Supply chain strategy assures that all parts, modules, and materials must be always nearby and spontaneously resupplied by using some specific techniques. Design strategy concurrently engineers the design of the product families and their flexible processes to build customized products on-demand from common parts and materials. Marketing strategy identifies product families that have a need for mass-customized products and can be economically built on demand.
