Situation

• Addressing increased wrist fatigue from handheld weight concentration and consumer needs for lightweight design
• Replacement of conventional ABS/PC with low-density PP composites while maintaining equivalent structural strength

Task

• Task 1: Goal: Achieving 60–90g weight reduction via high-stiffness MWCNT/PP composites
  • Challenge: Resolving filler agglomeration and enhancing interfacial bonding strength
• Task 2: Establishing thickness optimization process and defining strength lower-bound
  • Challenge: Managing exponential variable growth and computational resource shortages

Action

• Defining "Impact Energy Concentration Zones" to compress scale to 1/10 and improve efficiency by 30x
• Utilizing silane treatment and metal oxide nanorods to improve reinforcement dispersibility
• Selection of optimal molding methods through comparative analysis of numerical and empirical data

Result

• Achieving over 30% reduction in component weight by leveraging a 46% increase in tensile strength
• Establishment of cost-effective solutions through domain-driven data refinement
