The landscape of products has evolved from traditional physical goods to encompass online services accessible through digital platforms. User experience designers now prioritize usability in this digital era, emphasizing design characteristics for seamless product operation.
Product design extends across a spectrum, from high-end office furniture to intuitive software, where excellent design plays a pivotal role. At its core, product design involves the imaginative creation and refinement of goods to meet the desires and needs of a target market. The ultimate aim is to develop something innovative for commercial sale, involving strategic and operational actions to conceive, assess feasibility, and create usable products systematically.
The product design process is characterized by out-of-the-box thinking, prototype development, and iterative testing. Customer input is crucial in articulating market-specific problems that the designed goods intend to solve.
The significance of product design is underscored by its impact on companies. According to a Lucidpress survey, consistent design across communication channels can potentially increase a company's income and brand recognition by a factor of 33. Product design is crucial for delivering a memorable and delightful user experience, attracting new buyers, and fostering loyalty among existing customers.
A classic example of innovative product design is the ballpoint pen, created by László Jozsef Bró in 1938 as a solution to the issues associated with traditional fountain pens.

Tupperware containers also stand out as a game-changing product from the 1950s, showcasing exceptional American engineering with their airtight seal.
In the 21st century, where product differentiators are often scarce, branding becomes a crucial element in distinguishing one product from another. Product design emerges as a powerful tool, not just for functionality but also for creating a lasting and positive user experience that drives customer loyalty and business success.
Exploring the Nexus of Design Aesthetics and Price Expectation
Design aesthetics, a multifaceted aspect of product perception, is intricately intertwined with sociocultural, historical, and technological influences. Researchers have developed aesthetic design principles, such as Gestalt principles, emphasizing symmetry, proximity, similarity, continuance, repetition, and closure. The aesthetics of a product significantly impact the initial impression it makes on users, especially in a market saturated with products boasting similar functionalities. Users tend to consider a product's price only when it captures their attention or evokes emotions.
Prior research highlights that consumers form price expectations based on visual perceptions of extrinsic product attributes, particularly design aesthetics, before obtaining real price information. While both price expectations and attribute judgments influence consumer purchase intentions, limited research has delved into measuring how design aesthetics contribute to the perceived congruency between expected and real prices. This exploration gains significance as producers invest substantial resources in enhancing product competency through visual design, and the alignment between expected and actual prices holds sway over product design and sales performance.
The hierarchical strategy of aesthetic perception suggests that individuals categorize the aesthetics level of an object through pattern recognition without scrutinizing every detail. Consumers may perceive a product as beautiful or neutral based on their initial impression. The notion of "beautiful is good" links beauty to quality, with perceived quality serving as a cognitive evaluation of the intrinsic benefits sought by consumers. A visually appealing form can enhance consumer awareness of a product's usefulness and usability. However, when judging product quality is challenging, individuals often rely on extrinsic cues, such as design aesthetics, to infer quality or price.
In the realm of unfamiliar products or brands, where judging quality is challenging, consumers form price expectations based on visual cues like design aesthetics, without referencing previous price or brand information. This study intentionally removes brand information from products to create unfamiliarity, emphasizing the role of design aesthetics as crucial extrinsic cues influencing quality evaluation and price expectation. The intricate neural process of design aesthetics in product perception demands consideration in the product design process, with potential implications for market success.
Understanding Comprehensive Customer Requirements in Product Design
In the evolving landscape of consumer expectations, the traditional focus on functional aspects of product design is expanding to include softer elements such as appearance, aesthetics, affection, usability, and comfort. Recognizing the limitations of conventional design methodologies, which may overlook these critical factors, there is a growing emphasis on what is termed as "soft requirements." These soft requirements go beyond mere functionality to encompass aspects that contribute to user satisfaction, emotional connection, and overall product appeal.
Initial research in the realm of soft requirements primarily concentrated on visual factors, user-friendliness, and ergonomic considerations. As the market dynamics became more complex, methods like "design for wow" emerged, aiming to instill a sense of excitement in products. Kansei Engineering provided a systematic approach to translate customers' feelings and impressions into tangible product parameters, especially addressing emotional requirements. To comprehensively consider all factors, customer requirements and product features have been hierarchically categorized based on Maslow's hierarchy theory, Aesthetic-Meaning-Emotional taxonomy, and a holistic approach encompassing functionality, usability, and pleasure.
This study introduces the Emotional Design Classification (EDC), rooted in cognitive psychology, to comprehensively understand consumer requirements. EDC divides the human cognition process into visceral, behavioral, and reflective levels, each influencing and interacting with product design differently. Visceral cognition involves the initial emotional response to a product based on sensory input, impacting emotion directly and quickly. Behavioral cognition is the feeling experienced during product usage, relying less on consciousness. Reflective cognition is the highest cognitive level, involving introspection of visceral and behavioral cognition, influenced by information and cultural factors.
Requirements are classified based on these cognitive levels. Visceral requirements primarily pertain to appearance design, including auditory and somatosensory factors, influencing rapid buying decisions. Behavioral requirements, traditionally vital in design, now demand a balance between effective functionality and user experience, emphasizing learnability and usability. Reflective requirements are tied to the meanings of products, shaped by environment, culture, and identity, influencing customer loyalty. Accurate product positioning is crucial to satisfying reflective requirements and navigating the complex landscape of customer expectations. The topology structure established based on EDC provides a framework to integrate emotional considerations into innovative product design processes.
Integrated Approaches in Innovative Product Design
The pursuit of high-quality and rapid product innovation is crucial for maintaining competitiveness in today's market. However, innovation poses challenges for enterprises of all sizes, with potential impacts on their survival and growth. To enhance the quality and efficiency of product innovation, researchers have explored various principles from different perspectives, systematically defining innovation environments, content, goals, and processes. Numerous methods, including brainstorming, Theory of Inventive Problem Solving (TRIZ), and creative templates, have been developed to aid product designers in their innovative thinking. Computer-aided innovation (CAI) software and platforms further support these methods.
Given the complexity of the product development process, relying on a single method is often insufficient. Designers may face challenges such as overdependence on personal experiences, methods suitable only for specific aspects of the field, or partially innovative designs. Consequently, the integration of multiple methods during the innovation process becomes essential. Various studies, both domestic and international, have proposed models that integrate methods effectively. Examples include the FAST and TRIZ integrated tool application models, the analysis method combining 6W1H, function analysis, and trimming, and the fuzzy front-end model for generating innovative designs.
In essence, innovative product design involves creative thinking abilities, encompassing logical and non-logical activities like comparison, analysis, induction, transformation, analogy, and association. Existing integrated methods often address specific weaknesses of individual methods without comprehensively considering the entire design process based on designers' creative cognitive-thinking abilities. This results in limitations such as reduced information gathering, poor process data link-up, and invalid application methods. While computer-aided innovative design software can guide and assist designers in creative thinking, it cannot entirely replace human creativity. The collaborative process involves human-centric creative thinking, with computers supporting subsequent experiments, simulations, and other activities. As innovation continues to evolve, finding holistic and human-centered approaches to integrated design methods remains crucial for successful product development.
