Jaw Support Structure for Neck Posture Correction With Free Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing posture correction instruments, such as those described in Patent Literatures 1 and 2, are not designed to effectively address neck lowering and do not facilitate easy rehabilitation or daily activities while being worn.
Innovation Solution
A posture correction instrument with a jaw receiving portion and support portion that allows for wide neck movement, spherical motion, and adjustable length, which can be worn or fixed to a tabletop, and includes a support system that adjusts push-up force direction to correct neck posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed posture correction instrument is used to support the jaw and neck, then neck lowering is corrected, but the user cannot perform rehabilitation motions or daily activities easily
Solution Approach 1:
The patent applies the dynamics principle by making the jaw receiving portion capable of spherical movement rather than fixed. This allows the support portion to adapt to various neck positions and rehabilitation motions while maintaining postural support. The spherical joint enables dynamic adjustment during rehabilitation activities without compromising the corrective function.
Solution Approach 2:
The patent segments the instrument into distinct functional portions: a fixed support portion main body, a movable jaw receiving portion, and a wearing portion. This segmentation allows the support structure to remain stable while the jaw receiving portion provides motion freedom, resolving the contradiction between fixed support and dynamic rehabilitation capability.
2Reliability
If the jaw receiving portion is made fixed to provide stable support, then neck lowering is corrected effectively, but the degree of freedom for neck movement is reduced
Solution Approach 1:
The jaw receiving portion is designed with spherical movement capability, allowing it to adapt to various neck positions and movements. This dynamic design maintains stability for jaw support while providing the degree of freedom needed for natural neck motion and rehabilitation activities.
Solution Approach 2:
The patent applies local quality by making only the jaw receiving portion movable while keeping the support portion main body fixed. This localized mobility allows the jaw support to be stable and corrective, while the overall structure maintains its positional integrity during wear.
3Strength
If a plate-shaped jaw receiving portion is used, then structural strength is maintained, but adjustability and durability are reduced
Solution Approach 1:
The patent transitions from a fixed plate-shaped structure to a rod-shaped jaw receiving portion that can stretch and move spherically. This dynamic structure maintains structural strength through the rod configuration while providing superior adjustability for different user needs and rehabilitation stages.
Solution Approach 2:
The patent changes the geometric parameters of the jaw receiving portion from a rigid plate to a stretchable rod shape. This parameter change enables the structure to adapt to various conditions while maintaining durability, as the rod configuration is more resistant to deformation and better suited for dynamic movement.

AI summary
To provide a user-friendly instrument capable of easily performing motions of rehabilitation or the like and daily activities even in a worn state. A jaw receiving portion and a support portion are included. The jaw receiving portion includes a jaw receiving portion main body at one end thereof. The support portion includes a support portion main body, a shoulder portion, and a wearing portion. The support portion main body is configured to be able to support the jaw receiving portion. The shoulder portion is configured to be able to suspend the support portion main body from a shoulder of a user. The wearing portion is configured to be able to fix the support portion main body to a body of the user.
