Chair assembly with limb platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chair designs are not ergonomic, leading to discomfort for individuals with injured limbs, potentially worsening healing and causing strain for trainers or coaches treating the injuries, as they require uncomfortable positioning of the injured limb and trainer.
Innovation Solution
A chair assembly with an adjustable platform and arm configuration that allows for the comfortable propping up of limbs, featuring a seat, platform, and arm with adjustable height, angle, and pivot capabilities, along with legs and feet for stability, enabling ergonomic seating and treatment positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person sits on a current chair to have their limb treated, then the treatment can be performed, but the person experiences discomfort and reduced circulation in the limb
Solution Approach 1:
The arm is made adjustable in height along its longitudinal axis, allowing dynamic repositioning to achieve optimal limb elevation angles (30-60 degrees) that maintain circulation while providing comfort during treatment
Solution Approach 2:
The platform height and angle are made variable through the adjustable arm mechanism, enabling change in geometric parameters to optimize both comfort and circulation by positioning the limb at appropriate elevations
2Ease of operation
If towels or pillows are placed on a standard chair to support the limb, then some support is provided, but the underlying ergonomic problems are not solved and may be exacerbated
Solution Approach 1:
Instead of static support from towels or pillows, the invention provides dynamic, adjustable support through the height-adjustable arm and platform, enabling precise positioning that maintains proper circulation while supporting the limb
