🔥 I. Heating Performance - Core Focus: Precision, Depth, Safety
Heating Method & Penetration:
- Far-infrared vs. Conventional Heating: Prioritize far-infrared heating technology. It converts most energy into far-infrared rays (wavelength: 4–14 μm), which are readily absorbed by human tissue. This enables deeper penetration (up to 3–5 cm beneath the skin) for an internal warming effect, significantly improving blood circulation and metabolism. Conventional resistive heating only warms the skin surface.
- Heating Element Materials: Carbon fiber or ceramic heating elements are optimal—ensuring uniform heat distribution, stability, and longevity.
Temperature Control Precision & Range:
- Precision Control: Devices must accurately maintain set temperatures within ±1°C. Fluctuations compromise comfort, efficacy, and safety (e.g., low-temperature burn risks).
- Adjustable Range: A broad range (e.g., 35°C–50°C+) accommodates different body areas (joints, lower back, abdomen), user tolerance, and therapy goals (relaxation, deep relief, metabolic stimulation).
- Real-Time Monitoring: Real-time temperature display (screen/app) with multi-point sensors ensures uniform heating and safety compliance.
Warm-Up Speed:
- Target 40°C within 5–10 minutes—slow speeds reduce efficiency; rapid heating may cause discomfort.
Thermal Field Uniformity:
- Even heat distribution across the contact surface (e.g., belt, mat) is critical. Depends on heating element layout and internal thermal design.
🧲 II. Magnetic Performance - Core Focus: Strength, Type, Penetration
Magnetic Field Type:
- Static vs. Pulsed:
- Static Fields: Constant strength; simple tech, lower cost. Primarily improves microcirculation and pain relief. Penetration depends on field strength.
- Pulsed Fields: Strength varies at set frequencies. Superior penetration and bioactivity (e.g., ion exchange, neural modulation). Technically complex but more effective. As a PM, prioritize devices with scientifically tuned pulse frequencies.
- Alternating Fields: Rapid polarity shifts (a pulsed subtype). High penetration and bioactivity.
Magnetic Field Strength:
- Units: Gauss (Gs) or Tesla (T) (1 T = 10,000 Gs).
- Effective Strength: Focus on depth-delivered strength (e.g., to joints/muscles), not surface specs. Avoid products with inflated surface values but poor penetration.
- Optimal Range: Home/clinical devices should deliver 1,000–5,000 Gs (0.1–0.5 T) at target depths. Surface values may exceed 10,000 Gs—scrutinize penetration data.
- Adjustability: Field strength should be adjustable for sensitivity and needs.
Magnetic Penetration:
- Depends on magnet design (e.g., magnetic circuit, pole arrangement) and field type (pulsed/alternating > static). Ensure effective penetration through fat/muscle to target areas.
Field Uniformity:
- Uniform distribution avoids localized hotspots/weak zones.
🔈 III. Vibration Performance - Core Focus: Modes, Intensity, Precision
Vibration Modes:
- Diversity: Multiple modes (continuous, interval, wave, kneading, tapping) simulate massage techniques for muscle states (tension, soreness, relaxation).
- Intelligence: Auto-adjustment based on heat/magnetic settings or presets enhances efficacy.
Vibration Intensity:
- Adjustable Range: Broad intensity levels (gentle to deep percussion) for all users.
- Perceptible Gradation: Clear differentiation between intensity levels.
Frequency & Amplitude:
- Frequency (Hz): Range should be specified (e.g., 10–80 Hz). Low frequencies relax; high frequencies stimulate.
- Amplitude: Vibration displacement depth. Linked to intensity; deep tissue requires higher amplitude.
- Precision: High-quality motors ensure stable frequency/amplitude output with minimal noise.
🛡 IV. Integrated Performance: Heat + Magnetic + Vibration Synergy
Synergistic Effects:
- Heat (vasodilation) + Magnetism (microcirculation/ion modulation) + Vibration (muscle relaxation/lymph flow) delivers 1+1+1>3 results (e.g., pain relief, recovery).
- Programs should sequence modalities (e.g., pre-heat → magnetic/vibration therapy).
Smart Programs:
- Preset routines for body parts (neck, back, knees) and goals (relaxation, pain relief, post-workout) with auto-adjusted parameters.
Zonal Control (Premium Devices):
- Independent settings for different areas (e.g., upper/lower back) on large mats/belts.
⚠ V. Safety Performance - Non-Negotiable
- Overheat Protection: Redundant safeguards (e.g., multi-sensor monitoring, hardware limiters).
- EMC Compliance: Fields within safe limits (per IEC/FCC/CE standards). Shielding to prevent interference (contraindicated for pacemaker users).
- Electrical Protections: Overcurrent/voltage/short-circuit safeguards.
- Material Safety: Skin-contact materials (fabric/silicone) must be hypoallergenic, non-toxic, and heat-resistant.
- Auto Shutoff: Adjustable timers (15–60 mins) prevent prolonged use.
- Emergency Stop: Instant power cutoff.
🏗 VI. Durability & Reliability
- Component Quality: Industrial/medical-grade heating elements, magnets (coils for pulsed fields), motors, sensors, and PCBs.
- Robust Design: Optimized internal layout, shock resistance, heat dissipation, and reinforced housing/connectors.
- Cabling: Durable power/connection cables with secure ports.
- IP Rating (Optional): Splash resistance (e.g., IPX4) for sweat-prone environments.
