There are many facets to creativity, and the topic has a profound impact on society. Substantial and sustained study on creativity has been undertaken, and much is now known about the fundamentals and how creativity can be augmented. To draw these elements together, a framework was developed called the creativity diamond, formulated on the basis of reviews of prior work, as well as the consideration of 20 PhD studies on the topics of creativity, design, innovation, and product development. The framework embodies the principles that quantity of ideas breeds quality through selection, and that a range of creativity tools can provoke additional ideas to augment our innate creativity. The creativity diamond proposed is a tool consisting of a divergent phase associated with the development of many distinctive ideas and a convergent phase associated with the refinement of ideas. The creativity diamond framework can be used to prompt and help select which tool or approach to use in a creative environment for innovative tasks. The framework has now been used by many students and professionals in diverse contexts.
This paper asked participants to assess four selected expert-rated Taiwan International Student Design Competition (TISDC) products using four methods: Consensual Assessment Technique (CAT), Creative Product Semantic Scale (CPSS), Product Creativity Measurement Instrument (PCMI), and revised Creative Solution Diagnosis Scale (rCSDS). The results revealed that, between experts and non-experts, the ranking results by the CAT and CPSS were the same, while the ranking results of the rCSDS were different. The CAT, CPSS, and TISDC methods provided the same results indicating that raters may return the same results on creativity assessment, and the results are not affected by the selected methods.If it is necessary to use non-experts to assess creativity and the creativity results are expected to be the same with that of experts, asking non-expert raters to use CPSS to assess creativity and then ranking the creativity score is more reliable. The study offers a contribution to the creativity domain on deciding which methods may be more reliable from a comparison perspective.
In order to investigate the effect of graphene oxide (GO)/multi wall carbon nanotubes (WMCNTs) on the mechanical properties and low‐velocity impact response of magnesium‐based fiber metal laminates (FMLs), the FMLs specimens reinforced with GO, WMCNTs or their mixture were prepared, and quasi‐static tensile and low‐velocity drop hammer impact tests were performed. The tensile test results showed that the mechanical performance of FMLs could be improved by adding a certain concentration of nanoparticles. The tensile strength increased by 14.9% and 26.6% when the concentration of GO or WMCNTs is 0.6 wt%, respectively. Due to the agglomeration phenomenon, there are the opposite effect for the tensile strength of FMLs when the particle concentration is excessive. After the mixture of GO and WMCNTs was added to the epoxy matrix, the tensile strength of FMLs could still be increased by 12.8% at the GO to WMCNTs ratio of 0.6:0.9 (the overall concentration of particle is 1.5 wt%). And the elastic modulus is also significantly increased, but it has a negative effect on the ductility. The low‐velocity impact test results showed that the FMLs reinforced a mixture of GO and WMCNTs have greater peak impact load due to the lager stiffness. The FMLs reinforced with WMCNTs have better energy absorption capacity under impact load due to lager damage area.
Neurotechnology has been applied to gain insights on creativity-related cognitive factors. Prior research has identified relations between cognitive factors and creativity qualitatively; while quantitative relations, such as the relative importance of cognitive factors and creativity, have not been fully determined. Therefore, taking the creative design process as an example, this study using electroencephalography (EEG) aims to objectively identify how creativity-related cognitive factors of retrieval, recall, association, and combination contribute to creativity. The theoretical basis for an EEG-based decoding method to objectively identify which cognitive factors occur in a creative process is developed. Thirty participants were recruited for a practical study to verify the reliability of the decoding method. Based on the methodology, relationships between the relative importance level of the cognitive factor and creative output quality levels were detected. Results indicated that the occurrence of recall and association are reported with a high reliability level by the decoding method. The results also indicated that association is the dominant cognitive factor for higher creative output quality levels. Recall is the dominant cognitive factor for lower creative output quality levels.
