Adaptive Robotic Head Support for Neck Muscle Rehabilitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head braces for patients with head drop conditions, such as those resulting from neurological diseases or accidents, are inadequate as they restrict movement, cause muscle atrophy, and do not effectively support strengthening of neck muscles.
Innovation Solution
A head support system with multiple degrees of freedom, attached to the head via straps, connected to an adjustment system controlled by a processor and sensors. This system allows for real-time adjustments to support the head in various positions, promoting muscle strengthening and preventing atrophy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static neck braces are used to keep the head upright, then head support is provided, but head movement is constrained and muscle atrophy occurs
Solution Approach 1:
The patent transforms the static brace into a dynamic system with motors and sensors that can actively adjust head position and provide controlled support. The system moves from a fixed configuration to an adaptive one that can respond to patient needs while allowing movement.
Solution Approach 2:
The system incorporates sensors that detect head position and muscle activity, feeding this information back to the control system. This feedback loop enables the brace to automatically adjust support levels and allow appropriate movement while maintaining stability when needed.
2Reliability
If static neck braces are used to support the head, then head position is maintained, but muscle strengthening is prevented and atrophy occurs
Solution Approach 1:
The dynamic system can transition between providing full support and providing minimal support, allowing muscles to be activated during controlled movements. This dynamic adjustment enables both position maintenance and muscle strengthening.
Solution Approach 2:
The system changes the support parameter dynamically based on detected muscle activity and head position. By adjusting the level of support provided, the system creates conditions for muscle strengthening while maintaining head position stability when required.
3Adaptability or versatility
If manual adjustment of head braces is implemented, then support can be customized, but the adjustment process is complex and requires disengagement of the brace
Solution Approach 1:
Sensors provide real-time feedback on head position and support requirements, enabling automatic adjustment without manual intervention. The system self-regulates based on detected conditions, eliminating the need for complex manual procedures.
Solution Approach 2:
The system performs automatic adjustments based on sensor input and control algorithms, making the brace self-regulating. This eliminates the need for users to manually disengage and reposition components, greatly simplifying operation.
4Reliability
If passive suspension support is used, then head support is provided, but muscle activity is not utilized and atrophy progresses
Solution Approach 1:
The system detects muscle activity through sensors and uses this feedback to adjust support levels. When muscle activity is detected, the system reduces support to allow strengthening; when activity is insufficient, it increases support to maintain position.
Solution Approach 2:
The system transitions from passive suspension to active, adaptive support that responds to muscle activity. This dynamic adjustment creates an interactive system that both supports the head and promotes muscle strengthening through controlled engagement.
