Segmented Seat Support for Stable Inter-Seat Leg Rest Without Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long periods of sitting during travel, especially in cramped and awkward positions, lead to discomfort, muscle fatigue, and health issues such as deep vein thrombosis and sleep deprivation.
Innovation Solution
A seat support system comprising a support member with an anti-skid portion and connecting members that securely attach to both the front and back seat assemblies, providing a stable, extendable surface for legs and enhancing comfort by reducing friction and preventing sagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used between front and back seats, then the device complexity is reduced, but the support portion sags under load reducing stability
Solution Approach 1:
The support member is divided into multiple portions (first support portion, second support portion, third support portion) that can be independently positioned and secured. Each portion can be separately attached to the front seat assembly, back seat assembly, or side walls, distributing the load and preventing sagging without requiring a single complex rigid structure.
2Area of moving object
If the support member is made longer to extend further between seats, then the area covered is increased, but the weight of the support increases
Solution Approach 1:
Instead of using one long continuous support member, the invention uses multiple shorter support portions that can be independently positioned. These segments cover the same overall area but use less material and weigh less than a single long rigid support would require.
Solution Approach 2:
The support member is described as a flexible or semi-flexible structure that can conform to the space between seats. This flexible film-like construction provides adequate support area while maintaining low weight, as flexible materials can span distances with minimal material thickness.
3Reliability
If multiple connecting members are added to secure the support, then the reliability of attachment is improved, but the device complexity increases
Solution Approach 1:
The support system is designed to attach to multiple locations (front seat assembly, back seat assembly, side walls) using the same basic support member and connecting mechanism. This multi-functional attachment capability provides reliable securing without requiring different complex mechanisms for different attachment points.
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 seat support system alleviates discomfort and health risks by offering a stable, comfortable seating position that reduces pressure on legs and allows for better posture adjustment, promoting relaxation and sleep during travel.
Implementation Method 1
The support member (11) has an anti-skid layer (12).
