Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional wing deployment mechanisms are used, then wings can be deployed from airborne bodies, but the transmission function is inefficient and kinetic efficiency is reduced
Solution Approach 1:
The patent extracts and eliminates the intermediate cogwheel transmission component from the deployment mechanism. The propelling assembly directly drives the wings through arms connected to the wings' rotation axes, removing the cogwheels that caused inefficient transmission and high kinetic energy loss, thereby achieving direct and efficient force transmission.
2Adaptability or versatility
If cogwheel-based deployment mechanisms are used, then wings can be deployed, but the mechanism cannot adapt to varying loads on the wings
Solution Approach 1:
The patent implements a dynamic deployment mechanism where the propelling assembly can vary its rotational speed and torque output to adapt to changing loads on the wings during deployment. The arms connected to the wings' rotation axes allow for continuous adjustment of deployment forces, enabling the system to respond dynamically to varying aerodynamic loads rather than following a fixed mechanical gear ratio.
3Reliability
If complex deployment mechanisms are used, then wings can be deployed with controlled motion, but manufacturing and assembly costs increase
Solution Approach 1:
The patent segments the deployment mechanism into three simple, independent components: a propelling assembly that provides rotational motion, arms that transmit force from the propelling assembly to the wings, and the wings themselves with their own rotation axes. This segmentation eliminates complex interconnected mechanisms like cogwheels, making each component easier to manufacture and assemble while maintaining reliable controlled deployment through the coordinated action of these simple segments.
4Device complexity
If traditional packaging designs are used, then the mechanism can be integrated, but meticulous packaging requirements increase device complexity
Solution Approach 1:
The patent merges the propelling assembly's rotation axis with the arms that directly connect to the wings' rotation axes, eliminating the need for separate cogwheel housings and complex mounting structures. This merging of functions allows the mechanism to be packaged more simply within the airborne body, as the components can be directly integrated without requiring meticulous packaging design for intermediate transmission elements.

AI summary
Wing deployment mechanism for deploying a pair of wings from an airborne body, wherein their deployment in motion, each one around an axis, defines the wings' deployment plane relative to the airborne body, and wherein the mechanism is characterized by that it comprises a propelable assembly mounted in the airborne body and suited to a rotational motion around an axis that is substantially orthogonal in its direction to the wings' deployment plane, a pair of arms that are linked, each one, on its one side to the assembly and at distance from the assembly's rotation axis, and on its other side to an end of one of the wings and at a distance from the axis around which the rotational motion of the wing in the wings' deployment plane is enabled, and wherein the link of each one of the arms is performed in a manner that enables angular motion of each of the arms relative to the assembly and to the end of the wing unto which it is linked, and wherein propelling the assembly to rotational motion and actuating a momentum for turning the wing as a result by the arm that is connected to it bring about concurrent rotational motion of the pair of wings in opposing directions and to their deployment on the wings' deployment plane, a method for deploying a pair of wings from an airborne body that is implementable in such mechanism and an airborne body equipped with such mechanism.
