Situația dificilă
Dispozitivul de terapie cu laser de tip încheietura mâinii, cea mai recentă inovație a companiei ARICOM, utilizează radioterapie vasculară externă cu laser. Este conceput pentru iradierea locală a cavității nazale și a suprafeței corpului, oferind efecte terapeutice auxiliare, cum ar fi reducerea inflamației, ameliorarea durerii, scăderea vâscozității sângelui și scăderea nivelului de lipide din sânge.
In the early stages, ARICOM encountered persistent issues with their battery suppliers. Problems such as batteries failing to charge and having short discharge times plagued the device, and these issues remained unsolved for an extended period. Eventually, ARICOM turned to Cowon Battery for a solution. With the active and close collaboration of Cowon's battery engineers, these battery-related problems were effectively resolved, significantly enhancing the device's performance and reliability.
Abordarea de rezolvare a problemelor
După ce a primit dispozitivul de terapie cu laser defectuos de la ARICOM, Cowon a efectuat o analiză detaliată pentru a identifica cauzele problemelor. Ei au identificat motivele din spatele incapacității bateriei de a se încărca și timpul scurt de descărcare, apoi au dezvoltat o soluție pas cu pas.
1.Charging Issue: The primary reason the battery couldn't charge was due to over-discharge, which caused the battery to deplete completely and trigger low-voltage protection. This mechanism prevents the battery from charging further to avoid excessive damage.
Solution: Cowon's battery engineers conducted a series of comprehensive tests and determined that the original IC's over-discharge protection voltage was too low. They replaced it with an IC featuring a higher over-discharge protection voltage. Additionally, they calibrated the battery management system (BMS) to better handle low-voltage conditions, ensuring the battery could recover from over-discharge situations. This adjustment successfully resolved the charging issue, allowing the battery to charge efficiently even after deep discharge.
2.Short Discharge Time: The short discharge time was due to sev
