Seating system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating systems often encourage incorrect posture, leading to health issues such as back pain, spinal abnormalities, and breathing difficulties due to their standard sizing and support configurations.
Innovation Solution
An ergonomic seating system with a reduced seating surface and a sacral support surface, designed to maintain the pelvis in a neutral position, providing stable support at three anatomical points, thereby encouraging correct posture and minimizing pressure on internal organs, facilitating easier breathing and improved concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard-sized seat with broad seating surface is used, then manufacturing simplicity is maintained, but incorrect posture is encouraged leading to health problems
Solution Approach 1:
The seat is divided into distinct functional zones: a reduced seating surface area and a separate sacral support surface. This segmentation allows each zone to perform its specific function - the reduced seat prevents pelvic reclining while the sacral support provides targeted support at the sacrum, together promoting correct posture without requiring complex manufacturing
Solution Approach 2:
Instead of providing uniform support across the entire seat, the invention applies support locally at specific anatomical points. The sacral support surface provides localized support at the sacrum, while the reduced seating surface provides support only where needed. This local quality approach promotes correct posture while maintaining manufacturing simplicity
2Ease of operation
If a traditional lumbar support area is provided, then backrest support is enhanced, but natural lumbar lordosis becomes kyphosis and incorrect posture is encouraged
Solution Approach 1:
The invention extracts the lumbar support function from the traditional broad lumbar support area and relocates it to a specific sacral support surface. By taking out the support function and placing it at the sacrum rather than the lumbar region, the invention prevents the pelvis from reclining and maintains natural lumbar lordosis, avoiding the development of kyphosis
Solution Approach 2:
Instead of supporting the lumbar region as in traditional seats, the invention inverts the approach by supporting the sacrum. This inversion changes the support mechanism fundamentally - by supporting the sacrum and preventing pelvic reclining, the natural lumbar curvature is maintained rather than encouraged to become kyphotic
3Ease of operation
If the pelvis leans back on the backrest, then support comfort is increased, but thoracic kyphosis becomes more pronounced and shoulders rotate forward
Solution Approach 1:
The reduced seating surface area creates a preliminary anti-action by making it uncomfortable for the pelvis to lean back. The limited seat depth and reduced surface area prevent the user from reclining onto the backrest, thereby preventing the chain reaction that would lead to thoracic kyphosis and forward shoulder rotation before these postural deviations can occur
4Stability of the object's composition
If a broad seating surface is used, then seating stability is improved, but pressure on internal organs increases and diaphragmatic breathing is restricted
Solution Approach 1:
The seating surface is segmented into a reduced seat area and a separate sacral support surface. This segmentation provides stability through the three-point contact (two ischial tuberosities on the reduced seat surface, one point on the sacral support) while leaving the abdominal region uncompressed. The reduced seat surface area specifically prevents downward pressure on internal organs while maintaining seating stability
