Focus: Prioritize "Lightweight + Flexibility."
| Core Criteria | Specification | Rationale |
|---|---|---|
| ① Load Capacity | $ge 200text{kg}$ per platform (to accommodate 1–2 workers with tools). | Ensures safety and usability for small teams. |
| ② Size Adaptability | Folded width $le 0.8text{m}$ (to pass through doorways and elevators), adjustable platform height (e.g., $1.5text{–}4.5text{m}$). | Allows easy access and positioning in confined interior spaces. |
| ③ Additional Features | Must include guardrails ($ge 1.1text{m}$ high, for fall protection), anti-slip platform design (prevents slipping during work). | Enhances operator safety. |
Focus: Emphasize "Stability + Wind Resistance."
| Core Criteria | Specification | Rationale |
|---|---|---|
| ① Load Capacity | $ge 300text{kg}$ per platform (supports 2–3 people working collaboratively, including tool weight). | Necessary for multi-person jobs and heavy equipment. |
| ② Stable Structure | Equipped with adjustable base plates (to handle uneven ground, $pm 10text{cm}$ adjustment range), wind bracing ties/outriggers or ballast weights (wind resistance rating $ge text{Level } 6$). | Ensures structural integrity and safety in outdoor conditions. |
| ③ Material Standard | Use aluminum tubing with a wall thickness of $ge 2text{mm}$. Frame connections must have reinforcing ribs (to prevent swaying at high altitudes). | Guarantees robustness and reduces oscillation. |
Focus: Key is "Portability + Rapid Assembly."
| Core Criteria | Specification | Rationale |
|---|---|---|
| ① Assembly Time | $le 15$ minutes per person (modular clip/snap design, requiring no specialized tools). | Maximizes efficiency for quick deployment. |
| ② Storage Volume | Folded volume $le 0.5text{m}^3$ (easy to transport by vehicle). | Ensures convenient logistics across multiple sites. |
| ③ Durability & Safety | Platform surface with anti-slip tread patterns. Wheels must include locking brake devices (prevents sliding once fixed). | Ensures reliable use during rapid setup and teardown. |
