Foot support device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot support devices fail to provide adequate support and protection from bedding, are inconvenient to use, and are not portable.
Innovation Solution
A foot support device comprising sidewalls and a backwall that engage the lateral and plantar regions of the feet, allowing for adjustable positioning and collapsibility, enabling universal use and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an in-bed tent frame is used to elevate bedding over feet, then bedding weight is alleviated, but foot support is not provided and the device is inconvenient to use
Solution Approach 1:
The device is divided into two separate functional components: an in-bed frame for elevating bedding and a foot support device for providing foot support. This segmentation allows each component to be optimized for its specific function while being used together as a complete system.
Solution Approach 2:
The foot support device acts as an intermediary between the user's feet and the bedding, providing support and preventing direct contact with bedding while the in-bed frame elevates the bedding overhead.
2Object-affected harmful factors
If an in-bed tent frame is used to elevate bedding, then bedding weight is reduced, but the device requires mattress adjustment and bed-specific configuration
Solution Approach 1:
The foot support device is designed to be self-positioning on the mattress surface without requiring mattress lifting or complex assembly. The user simply places the device on the mattress and positions their feet, eliminating the need for technical adjustments.
3Strength
If previous foot support devices are designed to be robust, then foot support is provided, but portability is compromised
Solution Approach 1:
The foot support device utilizes a flexible, thin-walled hollow structure that maintains structural integrity and support capability while minimizing weight and bulk, enabling easy portability and storage.
4Reliability
If a foot support device provides comprehensive foot engagement, then foot support and protection are improved, but device complexity increases
Solution Approach 1:
Multiple wall structures (first sidewall, second sidewall, third sidewall, fourth sidewall, and backwall) are merged into a single integrated hollow structure that provides comprehensive foot engagement through its interior surfaces while maintaining structural simplicity.

AI summary
A novel foot support device includes a first sidewall adapted to engage the lateral side of a first foot, a second sidewall adapted to engage the lateral side of a second foot, and a backwall adapted to engage both the plantar region of the first foot and the plantar region of the second foot. In a particular embodiment, the first sidewall includes an inclined interior surface, the second sidewall includes an inclined interior surface, and the backwall includes an inclined interior surface. In another particular embodiment, the foot support device includes sidewalls and a backwall that can flatten and pivot relative to one another, facilitating a collapsible foot support device.
