Pad for improving sitting posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pads for improving sitting posture primarily focus on passively maintaining shape, neglecting the need for adaptive muscle adjustment and adequate support for the legs, which limits their effectiveness in maintaining correct posture and relieving hip joint pressure, leading to poor comfort and limited back health benefits.
Innovation Solution
A pad with elevated segments for supporting the pelvis from the front and back, a bridge part for supporting the lower end of the ischium or coccyx, and optional features like a hollow airbag design, pressure sensor, and alarming device to promote correct relaxed angles and muscle activation, facilitating blood supply and spinal alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pad only focuses on shaping and passively maintaining body shape, then the pad structure is simple, but the effectiveness in improving posture is poor
Solution Approach 1:
The pad is divided into multiple functional segments: first and second elevated segments for supporting the pelvis from front and back, a bridge part for supporting the lower ischium or coccyx area, and optional components like airbags and massage elements. This segmentation allows each part to perform a specific function that collectively improves posture effectiveness while maintaining reasonable structural complexity
Solution Approach 2:
The pad incorporates dynamic elements such as inflatable airbags that can adjust to different body shapes and sizes, and massage elements that can actively stimulate muscles. These dynamic components enable the pad to adaptively respond to user needs, enhancing posture improvement effectiveness beyond static shaping
2Ease of operation
If the pad only focuses on hip and waist curves, then the pad design is simple, but the comfort and back health benefits are limited
Solution Approach 1:
The pad is designed to perform multiple functions simultaneously: it supports the pelvis and lower back, relieves pressure on the ischium and coccyx, promotes blood circulation through elevated segments, and provides muscle stimulation through massage elements. This multi-functionality approach enhances both comfort and back health benefits without requiring separate devices
Solution Approach 2:
Different regions of the pad have specialized properties: the elevated segments provide firm support for pelvic alignment, the bridge part offers cushioning for the coccyx area, and massage elements are strategically positioned to stimulate specific muscle groups. This localized quality enhancement improves comfort and health benefits across different body regions

AI summary
A cushion for improving sitting posture, comprising a cushion body (1). The cushion body (1) can be placed on a plane. At least two hump portions (11 and 13) are formed on the cushion body (1). The two hump portions (11 and 13) are a first hump portion (11) and a second hump portion (13), respectively. The first hump portion (11) and the second hump portion (13) are used for supporting the parts of a human body corresponding to the front and back of the pelvis (3), respectively. The first hump portion (11) and the second hump portion (13) are arranged at an interval, so that a trench (12) is formed on the cushion body (1) between the first hump portion (11) and the second hump portion (13). The trench (12) is used for supporting the part of the human body corresponding to the lower end of the ischium or the lower end of the sacrococcyx. The cushion can relax the hip joint and surrounding muscles of the human body so as to facilitate blood supply, can ensure that the human spine always tends to maintain a correct curve so as to protect the lumbar vertebrae (2) of the human body, and can also further relax the cervical vertebrae and surrounding neck muscle tissues so as to prevent backache and headache.
