Dynamic Pelvic Support Seat for Posture Correction While Sitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating devices fail to effectively improve posture and prevent repetitive stress injuries associated with prolonged sitting, as they do not adequately adjust to the user's body shape, leading to gluteal spreading and incorrect pelvic alignment.
Innovation Solution
A seating apparatus with a foundation member featuring a front portion for upper legs and a bowl portion for the lower pelvic area, comprising central and lateral sections of varying flexibility, which applies upward and inward compressive forces to promote a forward lordotic position, rotating to adjust to the user's pelvic alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional seating devices with fixed shape are used, then manufacturing simplicity is maintained, but they fail to adjust to user's body shape causing incorrect pelvic alignment
Solution Approach 1:
The foundation member is designed to rotate between a first position (when user is not seated) and a second position (when user is seated), dynamically adapting to the user's body shape and pelvic alignment needs. This rotational capability allows the device to transition from a static to a dynamic configuration that conforms to individual user anatomy.
Solution Approach 2:
The foundation member is divided into multiple sections: a front portion for upper legs, a central portion, and a rear portion. This segmentation allows each section to independently respond to user body contours while maintaining overall structural integrity, enabling better adaptation without excessive complexity.
2Reliability
If conventional seating devices are used, then device simplicity is maintained, but they cause gluteal spreading and repetitive stress injuries
Solution Approach 1:
The device applies preliminary corrective action by rotating to a second position that pre-establishes proper pelvic alignment and prevents gluteal spreading before harmful postural habits can develop. The upwardly inclined rear portion proactively counteracts the natural tendency toward incorrect posture during sitting.
Solution Approach 2:
The foundation member changes its orientation parameter by rotating from a first position to a second position, altering the angle and inclination of support surfaces to optimize pelvic alignment. This parameter change transforms the device from a passive support to an active posture-correcting mechanism.
3Ease of operation
If the foundation member rotates to adjust to pelvic alignment, then posture correction is improved, but mechanical complexity increases
Solution Approach 1:
The foundation member performs self-adjustment by automatically rotating to the second position when the user sits down, without requiring external actuators, motors, or complex control systems. The user's body weight and positioning naturally trigger the rotational movement, making the system operate autonomously.
Solution Approach 2:
The foundation member acts as an intermediary between the seating surface and the user's body, mediating the interaction by rotating to accommodate pelvic alignment. This intermediary function allows the device to translate user positioning into automatic posture correction without direct mechanical intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus maintains correct pelvic alignment, reduces gluteal spreading, and stabilizes the pelvis in a lordotic curve, providing comfort and preventing repetitive stress injuries by dynamically supporting the user's posture during sitting.
Implementation Method 1
The lateral portion and the front portion collectively surround the central portion... apply an upwardly and inwardly compressive force when the lower pelvic area of the user is disposed in the bowl portion
Implementation Method 2
The bowl portion is configured to rotate between a first position when the user's lower pelvic area is not disposed in the bowl portion, and a second position, rotationally forward of the first position, when the user's lower pelvic area is disposed in the bowl portion

AI summary
An orthopedic device for improving posture while sitting, having a foundation member including a front portion for upper legs and a bowl portion for lower pelvic area. The bowl portion has a central portion and an upwardly inclined lateral portion. The lateral portion and the front portion collectively surround the central portion. A channel attachment is connected with one or more pelvic crest portions. The channel attachment portion connects over a concave recessed portion. The central portion has plural regions of varying flexibility and the lateral portion has plural regions of varying flexibility.
