Scenario-based functional modularization framework for consumer electronics using MFD and AHP: A case study on audio...

Area of Science:

• Engineering
• Product Design
• Sustainability Science

Background:

• Consumer electronics face pressure for personalization and sustainability, but traditional designs lead to underutilization and electronic waste (e-waste).
• Existing modularization methods prioritize production efficiency over multi-scenario adaptability and e-waste reduction.
• A systematic approach is needed to partition product functions based on distinct usage scenarios.

Purpose of the Study:

• To propose a novel scenario-based functional modularization framework for consumer electronics.
• To enhance product adaptability, personalization, and sustainability.
• To reduce functional redundancy and electronic waste (e-waste).

Main Methods:

• Integration of Modular Function Deployment (MFD) and Analytic Hierarchy Process (AHP) to quantify scenario-specific requirements.
• Development of a Modular Scenario Relevance Matrix (MSRM) for precise mapping of technical solutions to scenarios.
• Application of the framework to audio products for validation.

Main Results:

• Successful identification of a common module and scenario-specific functional modules (e.g., home entertainment, smart home, outdoor) for audio products.
• Demonstration of the framework's feasibility in designing adaptable consumer electronics.
• Quantification of scenario-specific requirements and mapping to technical solutions.

Conclusions:

• The proposed scenario-based functional modularization framework offers a systematic method for developing flexible and adaptable consumer electronics.
• Scenario-driven modularity enhances product sustainability by minimizing functional redundancy and e-waste.
• The approach effectively addresses diverse consumer demands for personalized and multi-scenario product usage.
