Low Clearance Medical Imaging Chair with Scissor Lift and Radiolucent Backrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile medical chairs are bulky and restrictive, failing to meet ADA accessibility standards while maintaining functionality, particularly in lowering height without compromising flexibility or armrest movement, which limits their use for patients with disabilities and various medical procedures.
Innovation Solution
A low-clearance mobile medical chair with a scissor lift mechanism, pivotally secured leg and backrest sections, and retractable armrests, allowing height adjustment, radiolucent design, and rotational capability to facilitate safe and accessible patient movement and positioning for diverse medical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic and mechanical equipment are added to provide varied functions, then the functionality and patient positioning capability are improved, but the device becomes bulky and cannot be lowered to ADA recommended height
Solution Approach 1:
The backrest is divided into two separate sections that can be independently positioned. The first back section and second back section can be adjusted to different angles and locked in place, allowing the chair to provide varied positioning capability while maintaining a compact structure that can be lowered to ADA recommended height of 16-19 inches.
2Ease of operation
If pivoting armrests mechanisms are added to facilitate patient access, then the ease of operation is improved, but the device complexity increases and limits chair movement when armrests are not upright
Solution Approach 1:
The armrests are designed to be completely removable from the chair structure. This eliminates the complex pivoting mechanisms found in traditional chairs while still providing easy patient access. The armrests can be detached and stored elsewhere, and when removed, they do not limit chair movement or maneuverability.
3Ease of operation
If the chair is lowered to ADA recommended height for accessibility, then the ease of operation is improved, but the functionality and flexibility are compromised
Solution Approach 1:
The chair incorporates a scissor lift mechanism with an actuator that enables dynamic height adjustment. The chair can be lowered to ADA recommended height of 16-19 inches for patient access and accessibility, then raised to elevated positions for various medical procedures. This dynamic adjustment capability allows the chair to maintain full functionality across different height positions.
4Adaptability or versatility
If radiolucent backrest is used for imaging procedures, then the adaptability for medical procedures is improved, but the structural strength may be reduced
Solution Approach 1:
The backrest is constructed from radiolucent materials that allow X-rays and other imaging procedures to pass through. Despite using these specialized materials, the backrest maintains sufficient structural strength to support patient weight and provide stable positioning during medical procedures through proper engineering and support structures.
