Design Steps

This paper illustrates a method, in conformity with Standards [10 - 14], regarding gear design. The optimization process using this method consists in reducing the number of design steps and also in its accuracy. This method takes into consideration the functionality of gears. This method, called also the operational method [1], involves 10 kinematic and dynamic restrictions, that provide a direct calculus of gears, without any iterations. The standard methods require successive iterations, until the appropriate result is obtained. The comparison between these methods is presented below. The kinematic and dynamic restrictions, being defined as mathematical functions, could easily be implemented in a programming language.

Element Method

A computer-aided methodology that applies the Finite Element Method (FEM) to gear design is presented in this work. The analysis takes into account the real tooth profile created by the involute flank of the tooth and the trochoidal fillet at the bottom of the tooth. The method enables gears with modified addendum and with any number of teeth to be modeled, so it can be used in CAD systems that require accurate models. Finally, the design process uses finite element modeling as an analysis tool to study the behaviour of components or products before they physically exist, thereby eliminating the need to create physical prototypes and providing a clean engineering design process.

Abstract This paper presents the use of constraint management techniques to design spur and helical gears. The constraints for gear design are presented in a declarative manner such that they can be incorporated in a general Design Shell environment. A declarative representation allows the designer to experiment with a number of different designs and perform “what-if” scenarios. Since spur gears form a subset of helical gears, the mathematical formulation is presented for helical gears only. The analysis of helical gears is based on the AGMA/ANSI Standard 2001-B88.

In the spring of 1973 it was decided to implement the language BCPL on the experimental microprogrammable computer RIKKE-1 being constructed in this department. The language was chosen to be the systems programming language for RlKKE-1, one argurment being the possibility of transferring the Oxford Operating system OS 8 to RIKKE-1. This paper describes the design process for an internal representation of OCODE, the resulting machine, the emulator, and the assembler, and finally there is a discussion of our experiences of running the OCODE machine during the past 8 months. Some future analysis and possible modifications are mentioned.

Technological Flexibility

End User Development offers technological flexibility to encourage the appropriation of software applications within specific contexts of use. Appropriation needs to be understood as a phenomenon of many collaborative and creative activities. To support appropriation, we propose integrating communication infrastructure into software application that follows an“easy-to-collaborate”-principle. Such an appropriation infrastructure stimulates the experience sharing among a heterogeneous product community and supports the situated development of usages. Taking the case of the BSCWeasel groupware, we demonstrate how an appropriation infrastructure can be realized. Empirical results from the BSCWeasel project demonstrate the impact of such an infrastructure on the appropriation and design process. Based on these results, we argue that the social construction of IT artifacts should be tightly integrated in the material construction of IT artifacts in bridging design and use discourses.

A design method for the geometric shape and modification of asymmetric spur gear was proposed, in which the geometric shape and modification of the gear can be obtained directly according to the rack-cutter profile. In the geometric design process of the gear, a rack-cutter with different pressure angles and fillet radius in the driving side and coast side was selected, and the generated asymmetric spur gear profiles also had different pressure angles and fillets accordingly. In the modification design of the gear, the pressure angle modification of rack-cutter was conducted firstly and then the corresponding modified involute gear profile was obtained. The geometric model of spur gears was developed using computer-aided design, and the meshing process was analyzed using finite element simulation method. Furthermore, the transmission error and load sharing ratio of unmodified and modified asymmetric spur gears were investigated. Research results showed that the proposed gear design method was feasible and desired spur gear can be obtained through one time rapid machining by the method. Asymmetric spur gear with better transmission characteristic can be obtained via involute modification.

Visual Appearance

Gestalt principles have previously served as qualitative guidelines for good visual design in art, architecture, and product design. This paper introduces a formal method to quantify classical Gestalt principles (proximity, continuity, closure, symmetry, parallelism, and similarity) for two-dimensional product representations. With the approach, designers use their judgment to divide a 2D representation of a new concept or existing design into its key atomistic elements, identify the most appropriate Gestalt principles that apply to the grouping of those elements, and then can objectively quantify the design’s adherence to those principles using mathematical functions of the design parameters. This quantification provides a tool to augment a design team’s own subjective interpretations in evaluating and communicating a product’s visual appearance at any stage of or throughout the design process.

In this design presents the design of electric pulse monitoring devices in residential homes. This tool is designed using the Raspberry Pi as a microprosessor. In the design process, this tool uses a light sensor (Light Dependent Resistor) to read the change of lights from green to red on the electric token, Camera Pi NoIR to take pictures of electric pulses, and SIM 800 to send SMS notifications. With the programming language used in the design of this tool is Language C. In monitoring the use of electric pulses, this tool is also designed to be able to send notifications automatically when the use of electric pulses has reached the minimum limit. Notifications sent will be received in the form of sms and email by the homeowner. It is expected that this tool can provide convenience to homeowners to monitor the use of electric pulses from a distance when the house is empty.

Customer Values

Service design has been generally discussed in the engineering field in recent years. Many manufacturers have been focusing more on services than on products themselves. To ensure the feasibility of designed services, a service designer should consider not only customer values but also the requirements of a service provider. However, there are few standard methods to deal with the service provider’s requirements and to reflect them in the service design. In this research, the authors suggest a method to describe service provider’s requirements for the service design based on the Service Engineering methodology. In addition, the authors propose a design process to analyze service providers’ requirements and adjust the specifications of a designed service in order to fulfill the requirements of both service providers and service receivers simultaneously.
