Solution Overview
Problem
Patients undergoing dialysis face challenges in charging their mobile devices during treatment due to safety concerns and limited battery life, leading to disruptions in their leisure activities and potential risks to the dialysis center's power system.
Innovation Solution
A holding device with an integrated charging unit is attached to a dialysis machine or patient bed, providing a safe and secure power supply to mobile terminal devices while incorporating a protection circuit to prevent overvoltage, undervoltage, short circuits, and thermal damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients use mobile terminal devices during dialysis treatment, then their leisure activities are enhanced, but the battery life is insufficient and devices may run out of power
Solution Approach 1:
A holding device with integrated charging unit acts as an intermediary between the dialysis machine's power system and the patient's mobile terminal device. The charging unit includes a protection circuit that mediates the power transfer, ensuring safe charging while extending the operational duration of the mobile device throughout the dialysis treatment period.
2Ease of operation
If patients connect their own chargers to the dialysis center's power outlets, then device charging is enabled, but safety risks increase due to potential power failures or fire hazards
Solution Approach 1:
The holding device with integrated charging unit serves as a safe intermediary between the dialysis machine's power system and the patient's mobile device. The protection circuit within the charging unit monitors and controls the charging process, preventing overvoltage, undervoltage, short circuits, and thermal damage, thereby eliminating the safety risks associated with direct connection to power outlets.
Solution Approach 2:
The charging unit incorporates a protection circuit that automatically monitors and protects against electrical hazards without requiring patient intervention. The system self-regulates the charging process, detecting defects and preventing harmful conditions, thereby providing safe charging service to patients.
3Reliability
If a protection circuit is integrated in the holding device, then safety is improved, but device complexity increases
Solution Approach 1:
The holding device with integrated charging unit is designed as a universal solution that can charge various mobile terminal devices while incorporating a comprehensive protection circuit. The protection circuit handles multiple protection functions (overvoltage, undervoltage, short circuit, thermal protection) within a single integrated system, achieving high reliability without proportionally increasing complexity.
