Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the engine position is fixed on the frame, then the structure is simple, but the pilot cannot optimize control and stability for different flight conditions
Solution Approach 1:
The patent implements adjustable engine mounting arms with multiple aperture positions that allow the engine to be repositioned along the lateral arms. This dynamic adjustment capability enables optimization of engine position for different flight conditions (takeoff, cruise, landing) while maintaining a relatively simple mechanical structure through standardized aperture-based positioning.
Solution Approach 2:
The mounting mechanism is segmented into discrete aperture positions along the lateral arms, allowing the engine to be positioned at specific intervals. This segmentation provides adaptability through multiple fixed positions while keeping the overall structure simple through standardized hole patterns and mounting brackets.
2Adaptability or versatility
If the harness is rigidly fixed to the frame, then the structure is stable, but the pilot cannot adjust to different body positions and flight orientations
Solution Approach 1:
The harness connection to the frame incorporates a pivot assembly that allows rotational movement between the harness and frame. This dynamic connection enables the pilot to adjust to different body positions and flight orientations while maintaining stable attachment through the pivot mechanism's controlled movement capability.
Solution Approach 2:
The pivot assembly is pre-configured with specific orientation ranges and stop positions that allow the pilot to anticipate and prepare for different flight attitudes. The preliminary design of the pivot mechanism ensures stable connection while providing predetermined adjustment positions for various flight conditions.
3Ease of operation
If heavy components are concentrated in one location, then the structure is simple, but the weight distribution affects control and flight duration
Solution Approach 1:
The engine mounting arms are designed to allow positioning of heavy engine components at variable distances from the pivot point. By adjusting the engine position along the lateral arms, the pilot can dynamically change the weight distribution and moment arm to optimize control responsiveness for different flight phases without requiring a completely reconfigurable structure.

AI summary
A back mounted flight machine comprises a frame comprising a connecting bracket, a pair of lateral arms extending from the connector bracket, and an engine mounted on each of the lateral arms in a selected position. A harness is mounted on the connecting bracket of the frame between the pair of lateral arms. Further, a fastening mechanism is provided for connecting the harness to the connecting bracket to permit relative movement between the harness and the frame in a plurality of orientations.
