Multi-Tier Cushion Set with Gel Pads to Reduce Pressure Sores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cushions fail to provide sufficient support for individuals with sedentary lifestyles or paralyzed lower limbs, leading to prolonged pressure on hipbones and compromised blood circulation, which can result in bedsores.
Innovation Solution
A cushion set comprising a pad with multiple sunken portions, a filling pad made of gel-infused viscoelastic foam, and a support pad set including upper and lower foam pads and a soft gel pad, designed to distribute pressure and promote blood circulation, with adjustable coupling mechanisms for customizable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cushion is used, then the cushion provides basic comfort, but it does not give sufficient support to the buttocks of users who lead a sedentary lifestyle or have paralyzed lower limbs
Solution Approach 1:
The cushion is divided into multiple independent support pads (first support pad, second support pad, third support pad) with different firmness levels, allowing targeted support for different body regions. The first support pad for the坐骨 area, second support pad for the thigh area, and third support pad for the calf area, each providing appropriate pressure distribution for their specific location.
Solution Approach 2:
Different regions of the cushion have locally optimized properties - the first support pad has higher firmness for structural support at the坐骨, while the second and third support pads have progressively softer characteristics for comfort and circulation in the limb areas. This local differentiation ensures both support and pressure relief where needed.
2Reliability
If a firm cushion is used to provide support, then support capability is improved, but blood circulation is compromised leading to bedsores
Solution Approach 1:
The cushion incorporates adjustable support mechanisms where the intensity and positioning of support can be modified based on user needs. The support pads can be adjusted in firmness and position to dynamically adapt to different users and conditions, balancing support with circulation requirements.
Solution Approach 2:
The cushion system allows adjustment of support parameters including firmness level, support position, and pressure distribution characteristics. By changing these parameters, the cushion can provide adequate support while maintaining blood circulation, preventing the harmful effects of both too-firm and too-soft configurations.
3Reliability
If a cushion with multiple support levels is designed, then support effectiveness is improved, but device complexity increases
Solution Approach 1:
The cushion is segmented into multiple independent support pads that can function independently or in combination. This modular segmentation provides multiple support levels and configurations without requiring a completely complex integrated system, as each pad can be adjusted or removed as needed.
Solution Approach 2:
The multiple support pads are designed to serve multiple functions - they can be used individually or in combination, adjusted for different users, and configured for various support needs. This multi-functionality reduces the need for entirely separate cushion systems for different conditions, simplifying the overall device complexity while maintaining support effectiveness.

AI summary
Provided is a cushion set including a pad, a filling pad, an envelope, and a support pad set. The pad has a first-tier sunken portion and a second-tier sunken portion. The filling pad is disposed in the second-tier sunken portion. The envelope is disposed on the pad. The envelope has a pocket-shaped body. A plurality of coupling portions is disposed at edges of the body. The support pad set includes an upper foam pad, a lower foam pad, and a soft gel pad. The support pad set is disposed in the body of the envelope. The soft gel pad corresponds in position to the filling pad of the second-tier sunken portion of the pad.
