Th...Ickes （1997） has mentioned that empathy is a complex form of psychological inference in which observation, memory, knowledge, and reasoning are combined to yield insights into the thoughts and feelings of others. The phenomenon of empathy has been discussed in philosophy, aesthetics, and psychology for many years. In the beginning of the 20th century, an extensive discussion on this phenomenon has been led by European intuition phenomenologists such as Husserl, Sartre, Brunswik, and Heider, etc. It is known that the theory of its development relates to understanding human feelings and emotions. Empathic design in the design field has developed emotional design, inclusion design and universal design, etc. Empathic design is an emerging issue in the design field. What are empathic design, designing process, design methodologies, and a strategic design model？ Why is empathic design important to the creative and designing processes？ Empathic design is one of the useful ways to understand interpersonal relationships that might influence the creative and designing processes, design strategies and innovation. Empathic design that emphasizes listening to the voice from customer＇s heart and designing this into design has been proved to be something the customer really needs in brand communication messages and brand values. This paper researches, investigates and gathers the research methodologies and combines a literature review, case study, structured interviews, and grounded theory. The structured interviews comprise four designers who worked in the brand design department, including two senior designers and two junior designers. Thus, a literature review is conducted in this research to discuss the empathic design model, explore founding theories and then seek to analyze and propose a structured empathic design model. Finally, the research presents an empathic design model to explain several denominations, which are empathic communication, empathic aesthetics, empathic innovation, empathic methodologies, empathic culture and others. The design creation process from abstract ideas to concrete manifestation for reference of design students, design teaching, and design practice.展开更多

As technology has evolved into various web fields, metaphors have become even more useful and at the same time more sophisticated. A current-generation site not only has an overall theme for the site, but the organization of the information and the navigational scheme is based on a metaphor of the theme, called a Web Metaphor. A web metaphor is a design element that helps the user to leverage their existing experience in the abstract environment of the web. In this study, an approach to a thinking process model for web design is proposed through the concept of metaphors, and a theoretical analysis based on creative thinking for solving design problems is studied. This study aims to provide a glimpse into the world of metaphors and how they can be used in user interface design, to analyze selected examples, and to introduce a model web design process. As the study of the essence of creative thinking in web design is ongoing, diverse possibilities for solving problems in web design can be found through the theoretical modeling of thinking in web design. This study will also explore strategic and effective web design by establishing a mental model for web designers based on the study of metaphors that will inspire the thinking of designers.展开更多

文摘Long-life energy storage batteries are integral to energy storage systems and electric vehicles,with lithium-ion batteries(LIBs)currently being the preferred option for extended usage-life energy storage.To further extend the life span of LIBs,it is essential to intensify investments in battery design,manufacturing processes,and the advancement of ancillary materials.The pursuit of long durability introduces new challenges for battery energy density.The advent of electrode material offers effective support in enhancing the battery’s long-duration performance.Often underestimated as part of the cathode composition,the binder plays a pivotal role in the longevity and electrochemical performance of the electrode.Maintaining the mechanical integrity of the electrode through judicious binder design is a fundamental requirement for achieving consistent long-life cycles and high energy density.This paper primarily concentrates on the commonly employed cathode systems in lithium-ion batteries,elucidates the significance of binders for both,discusses the application status,strengths,and weaknesses of novel binders,and ultimately puts forth corresponding optimization strategies.It underscores the critical function of binders in enhancing battery performance and advancing the sustainable development of lithium-ion batteries,aiming to offer fresh insights and perspectives for the design of high-performance LIBs.

文摘The growing prevalence of exercise-induced tibial stress fractures demands wearable sensors capable of monitoring dynamic musculoskeletal loads with medical-grade precision.While flexible pressure-sensing insoles show clinical potential,their development has been hindered by the intrinsic trade-off between high sensitivity and full-range linearity(R^(2)>0.99 up to 1 MPa)in conventional designs.Inspired by the tactile sensing mechanism of human skin,where dermal stratification enables wide-range pressure adaptation and ion-channelregulated signaling maintains linear electrical responses,we developed a dual-mechanism flexible iontronic pressure sensor(FIPS).This innovative design synergistically combines two bioinspired components:interdigitated fabric microstructures enabling pressure-proportional contact area expansion(αP1/3)and iontronic film facilitating self-adaptive ion concentration modulation(αP^(2/3)),which together generate a linear capacitance-pressure response(CαP).The FIPS achieves breakthrough performance:242 kPa^(-1)sensitivity with 0.997linearity across 0-1 MPa,yielding a record linear sensing factor(LSF=242,000).The design is validated across various substrates and ionic materials,demonstrating its versatility.Finally,the FIPS-driven design enables a smart insole demonstrating 1.8%error in tibial load assessment during gait analysis,outperforming nonlinear counterparts(6.5%error)in early fracture-risk prediction.The biomimetic design framework establishes a universal approach for developing high-performance linear sensors,establishing generalized principles for medical-grade wearable devices.

文摘While desalination is a key solution for global freshwater scarcity,its implementation faces environmental challenges due to concentrated brine byproducts mainly disposed of via coastal discharge systems.Solar interfacial evaporation offers sustainable management potential,yet inevitable salt nucleation at evaporation interfaces degrades photothermal conversion and operational stability via light scattering and pathway blockage.Inspired by the mangrove leaf,we propose a photothermal 3D polydopamine and polypyrrole polymerized spacer fabric(PPSF)-based upward hanging model evaporation configuration with a reverse water feeding mechanism.This design enables zero-liquiddischarge(ZLD)desalination through phase-separation crystallization.The interconnected porous architecture and the rough surface of the PPSF enable superior water transport,achieving excellent solar-absorbing efficiency of 97.8%.By adjusting the tilt angle(θ),the evaporator separates the evaporation and salt crystallization zones via controlled capillary-driven brine transport,minimizing heat dissipation from brine discharge.At an optimal tilt angle of 52°,the evaporator reaches an evaporation rate of 2.81 kg m^(−2) h^(−1) with minimal heat loss(0.366 W)under 1-sun illumination while treating a 7 wt%waste brine solution.Furthermore,it sustains an evaporation rate of 2.71 kg m^(−2) h^(−1) over 72 h while ensuring efficient salt recovery.These results highlight a scalable,energy-efficient approach for sustainable ZLD desalination.
