Problem
Traditional strength‑training equipment is static and requires manual weight adjustments, making it difficult to accommodate individual differences in limb length, mobility, and strength. This leads to suboptimal loading, increased injury risk, and inefficient use of space in gyms, physiotherapy clinics, and corporate wellness settings.
Solution
Sparkfield Core is a robotic, sensor‑driven training system that automatically measures a user’s range of motion and force capacity, then configures each exercise in real time to match those parameters. The device uses a patented parallel‑kinematic structure with two high‑precision electric actuators to generate controlled resistance along the sagittal plane, ensuring load is always applied in the direction of movement for joint‑friendly training. Software continuously monitors movement and force, adjusting intensity second‑by‑second to maintain optimal muscle activation without inertia or weight handling. All training data—including repetitions, muscle groups engaged, and performance trends—are captured, analyzed, and presented through an intuitive dashboard, enabling users and professionals to track progress, personalize programs, and make evidence‑based decisions.
Target Audience
Primary customers are fitness facilities, physiotherapy practices, corporate wellness programs, and micro‑studios that require space‑efficient, personalized strength training solutions for a diverse member base.
Features
- Patentierte parallel‑kinematische Mechanik mit zwei synchronisierten Hochpräzisions‑Antrieben für beliebige Bewegungsbahnen in der sagittalen Ebene
- Echtzeit‑Messung von Beweglichkeit und Kraft, automatisierte Startpositionierung und adaptive Belastungssteuerung während des gesamten Satzes
- Gewichtlose Widerstandsgenerierung (keine mechanischen Gewichte), wodurch keine Trägheit, kein Be‑ und Entladen und keine unkontrollierten Fall‑risiken entstehen
- Integrierte Sensorik und Software zur kontinuierlichen Optimierung der Muskelaktivierung und zur Vermeidung von Gelenkbelastungen
- Umfangreiche Datenerfassung und Analyse (Wiederholungen, trainierte Muskelgruppen, Leistungs‑Trend‑Grafiken) mit visualisierten Berichten für Trainer, Therapeuten und Nutzer
- Kompakte Bauweise (230 cm × 80 cm, ca. 300 kg) geeignet für Personen von 150 cm bis 200 cm, mit austauschbarer Sitzbank für sitzende und stehende Übungen
- Mehrere Anwendungsmodi (Fitnessstudio, Mikrostudio, Physiotherapie, betriebliche Gesundheit) und dynamisch anpassbare Trainingsmethoden (HIT, Zirkel, Supersätze)
