Abstract:
Prolonged sitting often results in discomfort, injury, and chronic pain, particularly for prehospital patients and manual wheelchair users who experience significant upper-limb pain and dysfunction. The Temperature Controlled Comfortable Chair (TCCC) addresses these issues by offering specialized relief and adaptable features. This study aims to develop a multifunctional chair to enhance comfort, mobility, and safety for individuals with varying medical needs. The TCCC integrates customizable sitting and sleeping arrangements, a temperature-regulated mattress, joystick-controlled mobility, and automatic lighting. Testing involved evaluating thermostat responses for heating and cooling functions and assessing the automatic lighting system under different light conditions. Results indicate that the TCCC effectively regulates temperature, maintaining comfort in varying weather conditions. The warming function facilitates drying, while the cooling function alleviates prickly heat. Automatic lighting activates in low-light scenarios, enhancing patient safety and addressing nyctophobia. The joystick-controlled mobility system, despite the chair's substantial weight, ensures effortless maneuverability. Data showed consistent performance of the automatic lighting feature across various light conditions, with specific lux levels triggering the DC light. The TCCC provides a comprehensive solution for prolonged sitting discomfort, integrating essential features to enhance user comfort and convenience. Its innovative design sets a new standard in ergonomic seating and sleeping solutions, suitable for both everyday and medical settings, emphasizing the importance of multifunctional and user-centric design in patient care.
