Feeding Chair with Multi-Axis Adjustable Armrest for Ergonomic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chairs for supporting individuals while feeding a baby lack adjustable and ergonomic features that allow for optimal positioning, leading to discomfort and inefficiency during feeding.
Innovation Solution
A chair with rotatable, horizontally and vertically movable armrests that include an upper portion extending along a horizontal plane and an angled portion, allowing for customizable support of the baby and the caregiver's forearm, along with a locking mechanism to inhibit unwanted movement, enabling ergonomic configurations through motorized actuators and user-selectable positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the armrest is made fixed and simple in structure, then the device complexity is reduced, but the adaptability and ergonomic support are insufficient
Solution Approach 1:
The armrest is designed with multiple degrees of freedom, allowing it to move vertically, horizontally, and rotate about a vertical axis. This dynamic configuration enables the armrest to adapt to different feeding positions and ergonomic requirements without requiring an overly complex fixed structure.
Solution Approach 2:
The armrest mechanism is divided into independent movement components: vertical adjustment mechanism, horizontal adjustment mechanism, and rotation mechanism. Each component handles a specific degree of freedom, simplifying the overall design while achieving high adaptability.
2Ease of operation
If the armrest is made movable and adjustable in multiple directions, then the ergonomic support is improved, but the device complexity increases
Solution Approach 1:
The armrest incorporates self-adjustment capabilities where the caregiver can easily reposition the armrest to different heights, horizontal positions, and rotation angles without requiring complex control systems or assistance. The mechanism allows intuitive manual adjustment.
Solution Approach 2:
The multi-directional armrest serves multiple functions: supporting the caregiver's arm, providing a rest position, and offering ergonomic support in various feeding configurations. This universal design consolidates multiple support needs into a single adjustable component.
3Adaptability or versatility
If the armrest allows free movement in all directions, then the adaptability is improved, but the stability during feeding is reduced
Solution Approach 1:
The armrest includes a locking mechanism that detects when the armrest reaches a desired position and automatically locks to maintain that position. This feedback system ensures the armrest remains stable during feeding while still allowing easy repositioning when needed.
Solution Approach 2:
The locking mechanism is designed to engage automatically when the armrest is positioned, preventing unwanted movement before feeding begins. This preliminary stabilization action ensures the armrest remains fixed during the feeding process.

AI summary
The present invention relates to a chair for supporting a person feeding a baby. The chair includes a seat. The chair includes an armrest operatively connected to the seat. The armrest is selectively rotatable about a vertical axis, and moveable forward/rearward, laterally inward/outward and vertically relative to the seat. The armrest is shaped to receive a baby thereon.
