Abstract The paper provides an overview of systematic design procedures and applications of compliant transmissions, which rely on elastic deformation to achieve, intended motion/force transmission function. The mechanisms described in this paper have compliance distributed throughout the structure without employing flexural hinges. Stroke-amplification mechanisms integrated with electrostatic linear actuators and thermal actuators in MEMS domain, and piezoceramic actuators ate illustrated as some of the applications of single-piece compliant transmissions. Additionally the concept of distributed compliance is illustrated with applications to shape-changing structures such as adaptive airfoils.

Cardan Joint

In this study, a compliant version of the Cardan universal joint is introduced. The original design consists of two identical parts assembled at right angle with respect to each other. The single piece part can be produced from planar materials; thus, it has the advantage of easiness in manufacturing. Dimensions of the mechanism are devised in order to satisfy the Cardan joint theory and to avoid an undesired contact between the identical parts. As a design example, a mechanism is dimensioned. The resultant stresses at flexural hinges of this sample are determined via finite element analysis method and torque transmission capability of this mechanism is determined. Further, this sample is manufactured and operated under a considerable output loading. Therefore, robustness of the compliant Cardan joint is verified with this prototype. As well, it is verified that the results of experiments are consistent with the theoretical approaches.

Design For Six Sigma

This study shows an application of the Design for Six Sigma (DFSS) Methodology in the field of medical engineering. This research aims to demonstrate the application of a systematic design approach in the development of the “Ocane”, an innovative concept of smart cane for visually impaired patients which was thought of in answer to the end user’s needs, deploying an easy to transport, locate, and adjust element with ultrasonic sensors and tactile feedback. DFSS is an analytical design methodology meant to organize project workflow in a sequence of specific steps. Other standardized design procedures such as Quality Function Deployment (QFD) and Stylistic Design Engineering (SDE) have been used to support DFSS in terms of targeting customer requirements and focusing on aesthetics for ergonomics analysis, respectively. First, the QFD process is introduced and applied to gather the final customer needs, completing the analysis with benchmarking and similar-thought products on the market. Afterwards, a description of the DFSS methodology and application to the case study was deployed. Thereafter, the SDE procedure is exposed by identifying the “Ocane” concept and development, and moving towards the completion of an inventive product with a creative design and careful attention to visually impaired clients’ requirements.

Recently, manufacturing companies have been moving into product-based service businesses in addition to providing the products themselves. It is not easy for engineers in manufacturing companies to create new service businesses. In order to design product-based services more effectively and efficiently, systematic design methods suitable for the service businesses have been proposed, which provide design processes, checklists, and patterns. However, inexperienced designers still feel difficulties because they cannot understand the meaning of the checklists and patterns. In this chapter, the authors propose knowledge transfer in product-based service design, in which structured design cases are used to understand and utilize the checklists and patterns in the service design method called DFACE-SI.

Poor sanitation is a major problem for health and water resources in many developing countries. Inexpensive but also attractive toilets could be a way to fight these problems. However, radical new ideas are needed to identify innovative solutions. Such novel ideas might be found by using systematic design methods that search nature for animals and plants that solve similar problems. The paper describes how four conceptual sanitation solutions for dry toilets solving problems with smell, cleaning and flies can be made in collaboration between a design engineer and a biologist using biomimetic design methods. The solutions have the potential to offer significant improvements compared to conventional non-water-based sanitation.

Traditional areas of application of fluid power systems are being challenged by alternative forms of energy transmission. In some cases this is because of environmental concerns associated with noise and leakage, in other applications the lack of systematic design methods for synthesizing fluid power systems has led to their replacement by electrical drives. This paper outlines some of the current research studies motivated by these challenges.

Compliant Parts

Compliant mechanisms have many advantages over their rigid-body counterparts. One disadvantage however is the fact that motion of the mechanism is associated with elastic energy storage in the compliant parts. This is a problem especially in cases where accurate force transmission is of primary concern, such as in medical graspers. A solution to this problem is to statically balance the elastic forces by the addition of a spring force compensation mechanism, such that the effect of the compliance is neutralized. The complete resulting mechanisms resulting from this concept are called statically balanced compliant mechanisms (SBCMs). This paper presents a feasibility study into the design of a grasper for medical purposes and demonstrates that the concept is possible and practically viable. It is shown that the compliant gripper of a laparoscopic forceps can be statically balanced with a single-piece compliant compensation mechanism, with a balancing error of only 0.03N while dimensions are such that the compensation part of the mechanism can be stored inside the hand grip of the instrument.
