Seating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating arrangements in operating rooms require hand-assisted adjustments, which are impractical for sterile environments and hinder portability.
Innovation Solution
A modular, hands-free adjustable seating apparatus featuring a foot-operated pedal to adjust seat height, with a seat mount and suspension arms allowing for easy disassembly and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand-assisted adjustment mechanisms are used for seat height adjustment, then the adjustment can be precisely controlled, but the surgeon's hands are occupied and contamination risk increases in sterile environments
Solution Approach 1:
A foot-operated pedal acts as an intermediary device between the surgeon and the seat adjustment mechanism. The pedal is connected to the height adjustment mechanism through a linkage system, allowing the surgeon to adjust seat height using foot motion instead of hand assistance, thereby maintaining sterile technique while achieving precise height control.
2Ease of operation
If conventional fixed-structure seating arrangements are used, then structural stability is maintained, but portability and ease of transportation are compromised
Solution Approach 1:
The seating apparatus is divided into multiple detachable segments including the seat pan, backrest, base, and height adjustment mechanism. These segments are connected through standardized interfaces that allow quick assembly and disassembly. The foot-operated pedal mechanism and suspension arms are designed as separate modules that can be easily attached and detached, enabling portable transportation while maintaining structural integrity when assembled.
3Ease of operation
If the seat is directly mounted to the seat mount without gap, then structural rigidity is improved, but ease of disassembly and portability are reduced
Solution Approach 1:
The seat is connected to the seat mount through adjustable suspension arms that allow controlled movement and gap variation. This dynamic connection enables the seat to be easily detached for portability while maintaining adequate structural support during use. The suspension mechanism provides both ease of disassembly and sufficient structural rigidity through its adjustable nature.

AI summary
Presented is a seating apparatus that is enabled to allow a doctor or a surgeon to achieve an appropriate sitting posture during surgery. The seating apparatus includes a seat mount, a strut, a back-rest, a pedal, a seat and a support base. The seat is connected to the seat mount through a fastening means such that the seat is suspended over the seat mount leaving a gap between the seat and the seat mount. The pedal is operatively coupled to a lower end of the strut and the pedal is configured to adjust height of the seat in a hands-free manner. The seating apparatus is modular and it provides an option to user to easily disassemble various components of seating apparatus for easy portability of the seating apparatus.
