Leg Support Bracket Spacing for Seated Personal Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tight seating spaces, individuals often struggle to maintain their personal leg space without exerting muscle force, leading to fatigue, discomfort, and potential pain, especially in long situations like air travel, where existing solutions are inadequate.
Innovation Solution
A personal passenger space support device featuring adjustable 'J' shaped brackets with a round cradle for each leg, connected by an adjustable interconnect to maintain lateral spacing, allowing users to relax without extending beyond their personal space, and can be easily broken down for storage and quick exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self muscle control is used to maintain personal leg space, then personal space is maintained, but fatigue and discomfort occur
Solution Approach 1:
The support device provides self-service by automatically maintaining leg positioning without requiring continuous muscle control from the user. The device structure itself performs the space-maintenance function that would otherwise require active human effort.
Solution Approach 2:
The support device acts as an intermediary between the user's legs and the seating environment. It mediates the interaction by providing structural support that prevents legs from encroaching on personal space while eliminating the need for direct muscle control.
2Ease of operation
If legs are relaxed without support, then muscle fatigue is reduced, but legs extend beyond personal space
Solution Approach 1:
The device enables passive relaxation while automatically maintaining space boundaries. The structural design of the support device itself ensures that relaxed legs remain within personal space without requiring active control or monitoring.
Solution Approach 2:
The support device preemptively prevents legs from extending beyond personal space by providing continuous structural restraint. This preliminary anti-action counteracts the natural tendency of relaxed legs to spread outward before the problem occurs.
3Reliability
If a rigid leg support structure is used, then personal space is maintained, but safety for quick exit is reduced
Solution Approach 1:
The support device transitions from a static rigid structure to a dynamic system that can rapidly change state. The collapsible design allows the device to shift from a space-maintaining configuration to a compact storage configuration quickly, enabling safe and rapid exit when needed.
Solution Approach 2:
The device is divided into separable components that can be independently manipulated. This segmentation allows the support structure to be quickly collapsed or removed, converting from a potential safety hazard into a portable storage configuration.

AI summary
A personal passenger space support device is disclosed as it may be implemented to comfortably support a user's legs at a predetermined spacing in the user's own personal space while in a seated position. An example of the device includes a first leg support configured for a user's right leg, and a second leg support configured for the user's left leg. An interconnect is configured to maintain the first and second leg supports at a predetermined lateral spacing to support the user's legs apart from one another without overhanging the user's own personal space.
