Bed-Mounted Backboard With Adjustable Leg and Ankle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A sedentary lifestyle and poor muscle strength in the trunk contribute to the high incidence of acute low back pain, with existing solutions being either costly or inconvenient for effective trunk muscle strengthening.
Innovation Solution
A rectangular board with adjustable legs and a foam-covered bar for performing trunk extension and flexion exercises on a conventional bed, allowing for adjustable stabilization and storage under the bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If exercise equipment is used to strengthen trunk muscles, then muscle strength improves, but cost and convenience deteriorate
Solution Approach 1:
The device is divided into separate functional components: a rectangular board for exercise support, adjustable legs for positioning, and a foam-covered bar for ankle stabilization. This segmentation allows each component to be optimized independently while maintaining overall simplicity and ease of assembly in a home setting.
Solution Approach 2:
The board serves multiple functions: it provides a stable surface for both prone back extension exercises and supine abdominal exercises. The adjustable legs can be configured for different bed heights and positions, making the single device versatile for various exercise types and user needs without requiring multiple specialized equipment pieces.
2Reliability
If stable exercise support is provided, then exercise effectiveness improves, but device complexity increases
Solution Approach 1:
The legs are designed to be adjustable rather than fixed, allowing users to modify the position and angle of the legs based on their specific exercise needs and bed configuration. This dynamic adjustability provides stability when needed while keeping the structure simple and adaptable, avoiding the complexity of fixed, over-engineered support systems.
Solution Approach 2:
The foam-covered bar acts as an intermediary element between the user's ankles and the board structure. It provides the necessary stabilization for effective exercise while distributing pressure comfortably, achieving reliable support without requiring complex mechanical restraint systems or additional stabilization mechanisms.

AI summary
An exercise device for the purpose of strengthening the trunk muscles is used on the top surface of a bed or a similar platform. The exercise device has a rectangular board with a first and second end, a first and second side, a top, and a bottom. A single pair of legs is attached to the first end of the board. A rigid foam covered bar spans the top of said rectangular board and is attached to the first and second sides of the rectangular board.
