TL;DR: In this paper, the authors provide designers and decision-makers with an overview of the underlying principles used in the reviewed methods along with the advantages and limitations of these methods, as well as an overall goal of the overall survey.
Abstract: The evaluation process of conceptual design alternatives is a critical point for companies which operate in fast-growing markets due to its influence on all subsequent phases with regard to cost, quality and performance of the end-product. While various methods exist that are able to successfully carry out this difficult and time-consuming process, many have drawbacks (e.g., inability to consider coupled decision, inability to incorporate uncertainty, etc). The growing number of articles on concept selection literature is an indication of the importance of effective design strategy and of its role in improving the competitiveness of an organisation. Accordingly, this paper surveys concept selection methods (CSMs) published between 1980 and 2008. Our overall goal is to provide designers and decision-makers with an overview of the underlying principles used in the reviewed methods along with the advantages and limitations.

TL;DR: A new evolutionary design tool is presented, which uses shape grammars and a grammar-based form of evolutionary computation, grammatical evolution (GE), which allows forms to be iteratively selected.

TL;DR: In this article, a comparative analysis of six design methods for biologically inspired design is presented, based on scrutiny of the methods, in relation to the support given towards the attainment of four goals (form optimisation, organisational effectiveness, multiple requirements satisfaction and paradigm innovation for improved functional performance), considered of paramount importance to typical design endeavours aiming at achieving innovative concepts.
Abstract: Design inspired by nature is getting to the forefront of the search for environmental sustainability. A number of design methods, intended especially to guide students and professionals from several disciplines in carrying out the development of biologically inspired design, have been proposed. The paper establishes a comparative analysis between six methods. These are presented in similar depth, with the parameters of analysis described. The analysis is based on scrutiny of the methods, in relation to the support given towards the attainment of four goals (form optimisation, organisational effectiveness, multiple requirements satisfaction and paradigm innovation for improved functional performance), considered of paramount importance to typical design endeavours aiming at achieving innovative concepts, optimisation of specific features or performance and environmental sustainability. The comparative analysis is intended to support designers in selecting a method that is adequate to the problem at hand. The analysis also identifies goals where the methods considered offer no or reduced support for their attainment, identifying the need for novel methodological proposals. As a conclusion, the requirement to integrate validation activities in the bionic design processes is emphasised.

TL;DR: In this article, a variable lift cam follower system is proposed, where follower lift varies according to the input or camshaft speed, and the height of the cam varies along the axis of the shaft and it slides in the axial direction.
Abstract: This work proposes a novel variable lift cam follower system. Here follower lift varies according to input or camshaft speed. The system comprises a trapezoidal shape cam with ping finite spline curve as displacement profile. The height of the cam varies along the axis of the shaft and it slides in the axial direction so that the lift of the cam varies. Sliding motion of cam was executed by actuating mechanism and it works on principle of centrifugal actuation. When input speed varies, due to centrifugal force, actuator initiates linear axial movement of bush and cam on the shaft. This axial movement of cam varies the follower lift with respect to speed. Various components of proposed mechanism are designed and fabricated by proper processes and assembled together with suitable provisions. The system is tested experimentally and follower lift was measured using the computerised measuring system. Results show that the mechanism works properly and is useful to get variable lift. The proposed mechanism can be used in automotive engines as a valve train for variable valve actuation with necessary modifications.

TL;DR: In this article, the authors suggest that sustainable design within a perspective of precaution can complement dominant preventive methods of decision-making used for ecodesign, and show how a precautionary approach can be used with the logic of sufficiency to complement the traditional preventive approaches based on efficiency for establishing/assessing sustainable solutions.
Abstract: This paper suggests that sustainable design within a perspective of precaution can complement dominant preventive methods of decision-making used for ecodesign. More specifically, it will show how a precautionary approach can be used with the logic of sufficiency to complement the traditional preventive approaches based on the logic of efficiency for establishing/assessing sustainable solutions. As a consequence precaution may allow designers to develop new areas of insight. Evidence suggests that environmental gains from technical improvements in product efficiency have historically been outweighed by an overall increase in consumption - rebound effects, where efficiency largely depends on technical innovations. Sufficiency relies on individual behavioural changes as well as on social innovation, improved well-being out of fewer goods and services. So a sustainable future can be founded on both efficiency (based on a preventive approach) and sufficiency (based on a precautionary approach).
