Table 4. Synthesis matrix: Aesthetics–function–sustainability

Synthesis dimensions	Aesthetic parameters (humanities)	Functional parameters (engineering)	Sustainability outputs	Key theoretical references
Emotional durability	Sensory resonance, unique fiber patterns, and biophilic texture	Structural integrity and mechanical resistance of materials	Extension of the product life cycle through affective bonding (preventing premature disposal)	Emotional design (Norman); Sustainable craft (Ingold)
Materiality agency	Wood as a “cultural text” and a carrier of collective memory	Structural integrity and mechanical resistance of materials	Material transformation of a commodity into a valued subject (consumption ethics)	New materialism (Bennett); Phenomenology (Pallasmaa)
Functional aesthetics	Organic beauty as a trigger for biophilic calmness	Optimization of material performance through modern engineering	Reduction of carbon footprint through the selection of ecologically durable natural materials	Functional aesthetics; Bio-aesthetics
