A rehabilitation assistant system incorporating a supporting unit, audio stimulation, acupoint stimulation, phototherapeutic, electronic stimulation, display and optical frequency-flashed stimulation, and an exercise unit, which provides simultaneous multi-modal therapies including binaural beats, laser light, near-infrared light, transcranial direct current stimulation, and virtual reality exercises, controlled by a central unit to enhance cognitive function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple stimulation modalities are applied simultaneously to treat cognitive impairment, then rehabilitation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple stimulation modalities (audio binaural beats, acupoint laser stimulation, phototherapeutic near-infrared light, electronic transcranial direct current stimulation, display virtual reality, and optical frequency-flashed stimulation) into a single integrated head-mounted device. The supporting unit is configured to correspond to the head shape and includes all stimulation units positioned to deliver simultaneous multi-modal therapy to the user's head and eyes, thereby improving rehabilitation efficiency while managing device complexity through unified integration.
Solution Approach 2:
The supporting unit serves multiple functions by housing and positioning all six different stimulation modalities in a single device structure. The supporting unit corresponds to the head shape and includes mounting positions for audio stimulation, acupoint stimulation, phototherapeutic stimulation, electronic stimulation, display, and optical frequency-flashed stimulation, allowing one device to perform what would otherwise require multiple separate devices.
2Adaptability or versatility
If multiple stimulation units are integrated in a single device, then treatment comprehensiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The control unit automatically coordinates and controls all six stimulation modalities based on preset commands and digital information stored within the device. The system can autonomously manage the simultaneous operation of audio stimulation, acupoint agents, near-infrared light lamps, electronic stimulation agents, display content, and optical frequency-flashed stimulation without requiring manual coordination of multiple separate devices, thereby maintaining treatment comprehensiveness while improving ease of operation.
3Measurement precision
If acupoint agents are positioned at multiple specific acupoints, then stimulation precision is improved, but device complexity increases
Solution Approach 1:
The acupoint setting base includes specific positioning structures for placing acupoint agents at precise locations: Baihui acupoint at the center of the top area, Shenting acupoint 4.5 finger distances forward from the center, and Fengchi acupoints 7 finger distances backward and separated by 2.25 finger distances. Each position is optimized for its specific therapeutic target, providing localized precision stimulation while the base structure manages the complexity of multi-point positioning.
