“…From the perspective of "technical system", studies on the low-carbon function structure are rare, while product eco-design have been discussed widely. Since low-carbon design is an important branch of eco-design (Ren et al, 2017), most product eco-design takes carbon emission reduction as one of the indicators. These studies about eco-design are partially useful for low-carbon design.…”

Product conceptual design plays a decisive role in carbon emission of the products. Unfortunately, the traditional design methods based on carbon footprint calculation are not suitable for the conceptual design stage, and the latest low-carbon conceptual design research mainly focus on technology development to reduce carbon emissions at the manufacturing stage and less on carbon emissions caused by the unsustainable human use. This makes low-carbon product conceptual design less effective. To address this, a low-carbon conceptual design method is proposed for improving existing products, in which an improved process of requirements elicitation and analysis is implemented firstly, and then the improvement strategies are proposed from the perspectives of technical system and human use to help establish a low-carbon function structure. The conceptual design of a boiling water dispenser is taken as a case study. As a result, 5 low-carbon design strategies and a low-carbon function structure were comprehensively obtained. Next, by calculating the energy consumption of the assumed ideal scenario, it can be found that the re-designed product can save 39.4% energy compared to the existing product in the use stage. The results showed that the proposed method is effective in the generation of low-carbon design schemes at the conceptual design stage.

“…It focuses on the exaggeration and settlement of internal contradictions to obtain ideal solutions based on 40 inventive principles and 39 standard engineering parameters. [12][13][14] TRIZ specialize in generating innovation ideas during new product development. In a word, AD focus on transition between functional requirements and physical structure, but cannot improve the innovative of product.…”

Modular design, Axiomatic design (AD) and Theory of inventive problem solving (TRIZ) have been increasingly popularized in concept design of modern mechanical product. Each method has their own advantages and drawbacks. The benefit of modular design is reducing the product design period, and AD has the capability of problem analysis, while TRIZ’s expertise is innovative idea generation. According to the complementarity of these three approaches, an innovative and systematic methodology is proposed to design big complex mechanical system. Firstly, the module partition is executed based on scenario decomposition. Then, the behavior attributes of modules are listed to find the design contradiction, including motion form, spatial constraints, and performance requirements. TRIZ tools are employed to deal with the contradictions between behavior attributes. The decomposition and mapping of functional requirements and design parameters are carried out to construct the structural hierarchy of each module. Then, modules are integrated considering the connections between each other. Finally, the operation steps in application scenario are designed in temporal and spatial dimensions. Design of cutter changing robot for shield tunneling machine is taken as an example to validate the feasibility and effectiveness of the proposed method.

“…7,[11][12][13] In addition, the theory of inventive problem solving (TRIZ) is a powerful methodology summarized from 2.5 million patents targeted at addressing technical and developmental problems. The TRIZ, acclaimed as the ''Midas touch,'' has already solved a considerable number of innovative problems for enterprises worldwide, such as low-carbon design, 14 the integrated design of the fixture and connection of friction stir welding based on TRIZ conflict theory, 15 the improved design of mouse based on TRIZ invention principles, 16 and the elimination of technological contradictions of new wind generating set based on TRIZ tools. 17 Moreover, among the innovative designs developed in the early design phase, the selection of the optimal design is essential for NPD.…”

This study proposes a new hybrid method that adopts the theory of inventive problem solving and the Kansei evaluation in quality function deployment processes to facilitate innovative new product design and evaluation in the early design phase. The hybrid model and method procedures consist of four stages. First, user satisfaction needs are identified based on a questionnaire of linear numeric rating scale, factor analysis, and an analytic hierarchy process, and the completeness and reliability of this identification are guaranteed by the use of Cronbach's coefficient alpha statistic. Second, crucial design zones are identified by a correlation matrix, and analyzing the interrelationship matrix at the quality function deployment to establish critical innovation points. Third, the main tools of the theory of inventive problem solving are applied to address these critical innovation points. As such, several innovative alternatives are designed by combining the suitable inventive principles, design rulers, and crucial design zones. Finally, a general and rough set for the Kansei evaluation of the best design alternative is presented. Innovative car seat design is conducted to scientifically and efficiently verify this proposed method.
