Thoracic Stabilizer with Feedback Sensors for Scapular Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercises fail to effectively strengthen the scapulo-thoracic muscles, particularly the serratus anterior, which are crucial for maintaining the neutral spine position and preventing spinal injuries due to sedentary lifestyles and lack of weight-bearing exercises, leading to poor posture and increased vulnerability to spinal pain and injuries.
Innovation Solution
A feedback exercise device with a spine contact member and two rigid planar members that provide tactile and potentially electrical or vibratory stimulation, along with an adjustable strap system, to secure the device on the thoracic curve and scapulae, allowing users to maintain correct posture and strengthen the scapulo-thoracic muscles during upper limb weight-bearing exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional exercises are used, then general muscle strengthening occurs, but the scapulo-thoracic muscles (serratus anterior) are not effectively strengthened
Solution Approach 1:
The device incorporates sensory means including a spine contact member and rigid planar members that provide tactile feedback to the user. Pressure-sensitive elements detect contact between the scapula and planar members, and vibration motors provide haptic feedback to guide proper scapular retraction and thoracic curve maintenance during exercise
Solution Approach 2:
The patent replaces traditional mechanical resistance equipment with a feedback-based system using pressure sensors and vibration motors. The electronic control system monitors muscle activation through pressure detection and provides real-time feedback, substituting complex mechanical exercise machines with a more versatile wearable device
2Measurement precision
If the device provides detailed sensory feedback and stimulation, then posture monitoring accuracy improves, but device complexity increases
Solution Approach 1:
The sensory means is divided into separate contact members: a spine contact member for detecting thoracic curve position and rigid planar members for detecting scapular contact. This segmentation allows independent monitoring of different postural parameters while keeping each sensor element relatively simple
Solution Approach 2:
The rigid planar members serve multiple functions: they provide a surface for scapular contact, act as structural support for the sensory means, and serve as reference points for posture detection. The vibration motors both stimulate muscle activation and provide feedback signals

AI summary
The invention provides an exercise device for strengthening muscles in the scapula-thoracic region. The device enables simulated weight-bearing action for the upper limb while maintaining good postural form. The device can also be used to provide feedback on good postural form. The exercise device comprises a spine contact member (26) to be positioned at the thoracic curve of a person (10), and two rigid planar members (28) which extend laterally from the spine contact member (26). The rigid planar members (28) are positioned over the scapulae of the person (10). The spine contact member (26) and associated rigid planar members (28) are held in position by straps (30) which pass over and under the shoulders of the person (10).
