Table 14 Technical evaluation and prioritization matrix of functional Requirements.
Functional requirement | Rank | Technical Challenge | Engineering Strategy | Priority category |
|---|---|---|---|---|
\(\:{FR}_{7}\) | 1 | Heavy hardware dependence; high frequency of use | Lightweight software combined with hardware reuse | Core Innovation |
\(\:{FR}_{4}\) | 2 | Bottlenecks in energy density; difficulty in optimizing BMS algorithms | AI-based predictive maintenance; preliminary research into solid-state batteries; explore alternative energy solutions | Core Innovation |
\(\:{FR}_{3}\) | 3 | Conflict between material strength and cost; high process complexity | Use Finite Element Analysis (FEA) to evaluate trade-offs among weight, strength, and cost for materials such as titanium alloys and carbon fiber. | Core Innovation |
\(\:{FR}_{5}\) | 4 | Decreased interface strength; sacrifice of compactness | Standardized interfaces; partial modularization | Differentiated Competition |
\(\:{FR}_{6}\) | 5 | High-cost components offer low marginal benefits | Directional sound field technology; selective investment | Differentiated Competition |
\(\:{FR}_{2}\) | 6 | High cost (e.g., PEEK), limitations in recycling technologies | Glass fiber reinforced plastic (GFRP), cost reduction via modification technologies | Supportive Function |
\(\:{FR}_{1}\) | 7 | Conflict between aesthetics and functionality; cost-sensitive | Conform to structural design; adopt minimalist approach | Supportive Function |
\(\:{FR}_{9}\) | 8 | Risk of structural weakening; limited applicability across scenarios | Quick-release design for key components (e.g., battery compartment) | Supportive Function |
\(\:{FR}_{8}\) | 9 | Declining demand under the trend of touchscreens | Conform to structural design; adopt minimalist approach | Supportive Function |
