Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If vertical take-off and landing aircraft operate close to the ground, then site space usage is reduced, but airflow and noise impact on the environment increases
Solution Approach 1:
The patent introduces a vertical dimension by using a take-off and landing pole that extends upward from the ground. The aircraft docks at an elevated position on the pole rather than at ground level, effectively moving the operation point to a higher vertical dimension. This resolves the contradiction by maintaining compact ground footprint while reducing harmful ground-level airflow and noise impact.
Solution Approach 2:
The take-off and landing pole serves as an intermediary structure between the ground and the aircraft. It provides an elevated docking platform that mediates the interaction between the aircraft and the ground environment, allowing the aircraft to operate close to the ground site while minimizing direct harmful effects on the ground level through the pole's protective structure.
2Ease of operation
If helicopter landing platforms are installed on building roofs, then take-off and landing capability is achieved, but site space constraints in urban areas are not adequately addressed
Solution Approach 1:
Instead of requiring horizontal roof space for traditional helicopter platforms, this invention utilizes the vertical dimension by extending a docking pole upward from the ground or building facade. The aircraft docks at an elevated point on the pole, transforming the space requirement from horizontal (roof area) to vertical (pole height), thereby solving urban space constraints while maintaining full take-off and landing capability.
3Productivity
If multiple aircraft operate simultaneously in urban areas, then transportation capacity increases, but limited land use conditions create restrictions
Solution Approach 1:
The take-off and landing pole is designed with multiple docking levels or positions along its length, allowing multiple aircraft to dock at different vertical levels simultaneously. This segmentation of the docking space into multiple vertical zones enables increased transportation capacity without requiring proportionally more ground area, effectively resolving the contradiction between productivity and land use constraints.
