Bodily Perception and Innovation in Design:Modern Practices of Embodied Cognition Theory

Inspired by Maurice Merleau-Ponty’s phenomenology of perception and the concept of“body-subject”,this study advances a new paradigm of“embodied”design thinking.This approach not only investigates how design can foster an organic connection between people and the world but also delves into the“embodiment of emotions”within design practices,thereby strengthening emotional resonance and empathy between design works and individuals.This transformation in design thinking holds significant importance for advancing and deepening research into design methodologies.The research aims to enhance the understanding of the intrinsic logic within design,aiding designers in creating works that resonate more profoundly with human daily productivity and life,and facilitating an emotional dialogue between the design and its users.Originating from a profound human-centered design philosophy and guided by Don Ihde’s theory of embodiment,the study begins with the functional relationships of bodily embodiment,employing phenomenological methods in design,enriched by in-depth case study analysis.Our research analysis has revealed three core logics of bodily embodiment in design:The logic of behavioral embodiment emphasizes innate and acquired human behavioral patterns;the logic of organ embodiment pertains to the interactions between internal organs and the external environment;and the logic of scenographic embodiment includes the design of empathetic scenes and subtler environmental layouts.In essence,this study underscores that modern design logic should consider the interplay between the human body,behavior,and the environment.Such Embodied Design logic offers new theoretical perspectives and guiding principles for future research and practical applications in design methodologies.

Motivational Issues in Visual Design Education: Improving Teaching Methods From the Perspective of Self-Determination Theory

learning while making the teaching process more targeted and effective.Motivation,as the key factor driving individuals to take action and achieve specific goals,directly affects students’enthusiasm and creativity.Teaching strategies based on motivation can improve educational outcomes.The Self-Determination Theory provides a framework for enhancing students’intrinsic motivation,emphasizing the fulfillment of three basic psychological needs:autonomy,competence,and relatedness.Satisfying these needs allows students to demonstrate stronger learning motivation and sustained interest.Higher education instructors can support autonomy by giving students more choices,allowing them to create based on their interests,thus fostering creativity and increasing engagement.Additionally,teachers should provide competence support by setting appropriately challenging tasks,helping students gradually improve their skills and confidence,and enhancing their sense of competence.Finally,relatedness support emphasizes creating a collaborative learning environment where students can strengthen emotional connections and perceive the value of learning through group cooperation and discussions.Optimizing visual design education not only requires attention to motivation issues but also necessitates designing teaching strategies based on the Self-Determination Theory.Through support for autonomy,competence,and relatedness,educators can effectively stimulate students’intrinsic motivation,and enhance their creativity,problem-solving abilities,and interest in long-term learning.This approach makes education more meaningful and valuable,helping to cultivate more outstanding design talents.

Optimal design theories of tuned mass dampers with nonlinear viscous damping

Optimal design theory for linear tuned mass dampers （TMD） has been thoroughly investigated, but is still under development for nonlinear TMDs. In this paper, optimization procedures in the time domain are proposed for design of a TMD with nonlinear viscous damping. A dynamic analysis of a structure implemented with a nonlinear TMD is conducted first. Optimum design parameters for the nonlinear TMD are searched using an optimization method to minimize the performance index. The feasibility of the proposed optimization method is illustrated numerically by using the Taipei 101 structure implemented with TMD. The sensitivity analysis shows that the performance index is less sensitive to the damping coefficient than to the frequency ratio. Time history analysis is conducted using the Taipei 101 structure implemented with different TMDs under wind excitation. For both linear and nonlinear TMDs, the comfort requirements for building occupants are satisfied as long as the TMD is properly designed. It was found that as the damping exponent increases, the relative displacement of the TMD decreases but the damping force increases.

Hashin Failure Theory Based Damage Assessment Methodology of Composite Tidal Turbine Blades and Implications for the Blade Design

A damage assessment methodology based on the Hashin failure theory for glass fiber reinforced polymer(GFRP)composite blade is proposed. The typical failure mechanisms including the fiber tension/compression and matrix tension/compression are considered to describe the damage behaviors. To give the flapwise and edgewise loading along the blade span, the Blade Element Momentum Theory(BEMT) is adopted. In conjunction with the hydrodynamic analysis, the structural analysis of the composite blade is cooperatively performed with the Hashin damage model. The damage characteristics of the composite blade, under normal and extreme operational conditions,are comparatively analyzed. Numerical results demonstrate that the matrix tension damage is the most significant failure mode which occurs in the mid-span of the blade. The blade internal configurations including the box-beam, Ibeam, left-C beam and right-C beam are compared and analyzed. The GFRP and carbon fiber reinforced polymer(CFRP) are considered and combined. Numerical results show that the I-beam is the best structural type. The structural performance of composite tidal turbine blades could be improved by combining the GFRP and CFRP structure considering the damage and cost-effectiveness synthetically.

Improved PSO algorithm based on chaos theory and its application to design flood hydrograph

The deficiencies of basic particle swarm optimization （bPSO） are its ubiquitous prematurity and its inability to seek the global optimal solution when optimizing complex high-dimensional functions. To overcome such deficiencies, the chaos-PSO （COSPSO） algorithm was established by introducing the chaos optimization mechanism and a global particle stagnation-disturbance strategy into bPSO. In the improved algorithm, chaotic movement was adopted for the particles＇ initial movement trajectories to replace the former stochastic movement, and the chaos factor was used to guide the particles＇ path. When the global particles were stagnant, the disturbance strategy was used to keep the particles in motion. Five benchmark optimizations were introduced to test COSPSO, and they proved that COSPSO can remarkably improve efficiency in optimizing complex functions. Finally, a case study of COSPSO in calculating design flood hydrographs demonstrated the applicability of the improved algorithm.

Fundamental Issues Towards Unified Design Theory of Recycled and Natural Aggregate Concrete Components

In the past 20 years,recycled aggregate concrete(RAC),as a type of low-carbon concrete,has become a worldwide focus of research.However,the design methodology for RAC structural components remains a challenge.Consequently,demands for a unified design of natural aggregate concrete(NAC)and RAC components have been presented.Accordingly,this study analyses the necessity of a unified design theory and provides an in-depth demonstration of the strength determination,compressive constitutive relationship,and design method of concrete components.The coefficient of variation of RAC strength is found to be generally higher than that of NAC strength.The compressive and tensile strengths of RAC can be defined and determined using the same method as that used for NAC.The uniaxial compressive constitutive relationship between NAC and RAC has a unified mathematical expression.However,the elastic modulus of RAC decreases,and its brittleness exhibits an increasing trend compared with that of NAC.Finally,to unify the design formulae of RAC and NAC components for bearing capacity,modification factors for RAC components are proposed considering safety and reliability.Additionally,the feasibility of the proposed unified time-dependent design theory is demonstrated in terms of conceptual design and structural measures considering the effects of strength degradation and reinforcement corrosion.It is believed that this study enriches and develops the basic theory of concrete structures.
