Wearable Spinal Angle Sensor for Posture Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for correcting sagittal imbalance often require limiting a user's range of motion, which can restrict daily activities and fail to effectively maintain proper posture, leading to chronic back pain and increased risk of injury.
Innovation Solution
A wearable device with sensors and a controller that measures the angle of the spine relative to a reference plane, providing audible, visual, or tactile warnings when the user approaches an undesirable posture, while allowing a predetermined range of motion and optionally mechanically limiting further movement to prevent harmful flexion or extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices force the user to maintain correct posture by limiting range of motion, then posture correction is achieved, but the user's ability to perform daily activities is unnecessarily restricted
Solution Approach 1:
The device incorporates sensors that continuously monitor spinal orientation and provide real-time feedback to the user through alerts when undesirable posture is detected. This feedback mechanism enables users to self-correct posture without mechanical restriction, resolving the contradiction between effective posture correction and user mobility by replacing forced immobilization with informed voluntary control.
2Reliability
If the posterior tension band is weakened due to aging and muscle atrophy, then maintaining correct posture becomes difficult, but conventional devices that immobilize the back fail to address the underlying muscle weakness
Solution Approach 1:
The device empowers users to independently monitor and correct their own posture through sensor-based detection and user-friendly alerts. This self-service approach eliminates the need for complex mechanical immobilization structures, addressing both the need for reliable posture maintenance and the desire to avoid unnecessarily complicated device designs.
3Loss of information
If sensors and warning mechanisms are added to provide real-time posture monitoring, then posture awareness is improved, but device complexity increases
Solution Approach 1:
The device extracts only the essential function of posture monitoring and feedback, implementing a streamlined system with sensors, a controller, and warning mechanisms. By focusing on the core information needs (spinal orientation detection and alerting) rather than comprehensive biomechanical analysis, the device provides valuable posture information feedback while keeping the system relatively simple and manageable.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to maintain proper posture during daily activities by alerting them to unsafe spinal orientations and allowing flexible movement within a safe range, thereby reducing the risk of back pain and injury.
Implementation Method 1
at least one sensor configured to measure the angle of the first portion of the user's body relative to a reference

AI summary
The present invention relates to apparatus and methods for warning a user about undesirable motion of a first portion of the user's body relative to a second portion of the user's body. In one representative embodiment, an apparatus for warning a user about motion of a first portion of the user's body relative to a second portion of the user's body comprises at least one sensor configured to measure the angle of the first portion of the user's body relative to a reference. The sensor is configured to be worn on the user's body, and is in communication with a controller. A warning mechanism is also in communication with the controller, and the controller is operable to activate the warning mechanism upon movement of the first portion of the user's body relative to the second portion of the user's body beyond a predetermined angle relative to the reference.
