Solution Overview
Problem
Existing posture correction devices are not effectively customizable, flexible, or adaptable to user-specific attributes, often exacerbating posture-related conditions due to their weight and ergonomic design issues, and lack automatic operation for unskilled users.
Innovation Solution
A wearable device with a flexible resting pad, a deformable back stretcher, and a sensor unit that uses a displacement mechanism and electrical motor for automatic posture correction, combined with LED therapy for chronic pain relief, allowing for customization and adaptability to user-specific factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional posture correction devices are used, then posture alignment is provided, but the devices are heavy and cause additional stress on shoulders
Solution Approach 1:
The device is divided into multiple independent components: a lightweight headrest assembly, a separate supporting unit with back stretcher, and modular adjustment mechanisms. This segmentation allows each component to be optimized for minimal weight while maintaining functional effectiveness for posture correction.
Solution Approach 2:
The headrest and supporting structures utilize flexible, thin-shell designs that provide necessary structural support for posture correction while minimizing material usage and overall device weight. The flexible materials conform to user anatomy without requiring heavy rigid frameworks.
2Reliability
If manual manipulation devices are used, then posture correction is provided, but they lack flexibility and adaptability for unskilled users
Solution Approach 1:
The device incorporates self-adjusting mechanisms including automatic sensing systems that detect user posture and automatically adjust the headrest position and back stretcher tension without requiring manual manipulation. This eliminates the need for user skill while maintaining effective posture correction.
Solution Approach 2:
Integrated sensors provide real-time feedback on user posture and device positioning, automatically adjusting support forces and alerting users when optimal posture is achieved. This closed-loop feedback system ensures reliable correction while requiring minimal user input or expertise.
3Adaptability or versatility
If stretchable materials with adjustable constructions are used, then customization is improved, but the devices become heavier
Solution Approach 1:
The device achieves customization through electronic parameter adjustment of motorized components and inflatable elements rather than adding physical adjustment mechanisms. This allows extensive adaptability for different user sizes and preferences while maintaining lightweight construction through minimal mechanical components.
4Reliability
If straps are tightened for proper support, then posture alignment is improved, but additional stress is caused on shoulders
Solution Approach 1:
The device employs counterbalancing support forces through strategically positioned back stretchers and adjustable shoulder supports that offset the weight and pressure of tightening straps. This distributes the load across multiple contact points, maintaining effective posture alignment while preventing concentrated stress on shoulders.

AI summary
A wearable device for detection of a posture deviation of a body of a user, and to provide proper alignment thereon, comprises a resting pad adapted to cover a back region of the body of the user, wherein the resting pad includes an internal surface oriented towards the back region, and an external surface oriented away from the back region, a supporting unit adapted to be attached with the resting pad, at the external surface, wherein the supporting unit further includes a back stretcher adapted to be deformed through flexure, and a flexing mechanism adapted to cause the flexure of the back stretcher and a sensor unit configured to determine deviation in the posture of the body of the user. Further, the resting pad is made of a flexible material to accommodate the flexure of the back stretcher.
