Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional single arm support structure is used, then the structure is simple, but it cannot provide sufficient lateral support and control for bi-wing configurations
Solution Approach 1:
The arm support structure is divided into two separate arms (first arm and second arm) that can be independently positioned and controlled. Each arm can be adjusted to different angles and positions to provide optimal support for the bi-wing configuration, allowing the system to achieve greater lateral support capability while maintaining manageable complexity through modular design
Solution Approach 2:
The arm support structure is designed to accommodate multiple wing configurations (bi-wing, single wing, etc.) using the same basic mechanism. The arms can be adjusted to different positions and angles to support various configurations, making the system universally applicable while providing the necessary lateral support for each specific configuration
2Adaptability or versatility
If fixed arm positions are used, then the structure is simple to control, but it cannot adapt to different wing configurations and attack angles
Solution Approach 1:
The arm support structure incorporates adjustable mechanisms that allow the arms to be dynamically repositioned according to different wing configurations and attack angles. The arms can be rotated and positioned at various angles, transforming the static structure into a dynamic system that adapts to different operational requirements while maintaining controlled complexity through defined adjustment ranges
Solution Approach 2:
The adjustable arm mechanism uses nested components where one arm can be positioned relative to another, with each arm having its own adjustment capabilities. This nested arrangement allows multiple degrees of freedom and configuration options within a compact structure, achieving high adaptability without proportionally increasing overall system complexity
3Stability of the object's composition
If no lateral support is provided, then the structure is simpler, but the wing configuration cannot maintain proper orientation and positioning
Solution Approach 1:
The arm support structure functions as a counterbalancing mechanism that provides lateral support to counteract aerodynamic forces and maintain proper wing orientation. The arms are positioned to provide opposing support forces that stabilize the wing configuration against destabilizing lateral forces, ensuring stable operation while adding only the necessary support elements

AI summary
An apparatus for moving a patient on a pad and holding the pad in place on a surgical table. An upper member and a lower member having wings extending from opposite sides are configured and arranged to secure the position of the arms. In this position the arm has been securely wrapped without use of the patient's body weight, and the arm can be easily unwrapped by reversing the steps above, without the necessity of repositioning the patient (to get their body weight off of the device or a draw sheet), for access to the arm during the surgical procedure. Access may be necessary for anesthesia monitoring lines, invasive arterial lines, non-invasive blood pressure cuffs, SPO2 finger probes, and intravenous lines needed for medications and fluid delivery.
