Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power paragliders face issues with wind folding, line twisting, high manufacturing costs, and limited high-speed flight capabilities due to their cloth canopy and flexible line connections, which affect stability and control during takeoff and flight.
Innovation Solution
A paradrone design featuring a canopy with a parafoil supported by a horizontal and longitudinal canopy frame, connected via a connection rod without lines, and equipped with a servomotor unit to adjust the attack angle and direction, allowing for improved stability, reduced manufacturing costs, and enhanced flight capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible lines are used to connect the canopy and drive control unit, then the canopy can be easily positioned above the drive control unit, but the lines may twist from side to side causing uncontrollable conditions
Solution Approach 1:
The patent removes the flexible lines that connect the canopy and drive control unit, replacing them with a rigid connection structure. This extraction eliminates the source of twisting and uncontrollable conditions while maintaining the functional connection between components.
Solution Approach 2:
The connection system is segmented into distinct rigid components (canopy frame, connection rod, drive control unit mounting) rather than using a continuous flexible line. This segmentation allows each component to maintain its structural integrity and position without twisting.
2Ease of manufacture
If flexible lines are used to connect the canopy and drive control unit, then the canopy can be connected to the drive control unit, but it is not easy to takeoff
Solution Approach 1:
The takeoff process is segmented into distinct phases: ground preparation with the rigid structure already positioned, liftoff, and flight. The rigid connection structure is pre-positioned on the ground, eliminating the need to manage flexible lines during takeoff preparation.
Solution Approach 2:
The rigid connection structure between canopy and drive control unit is established before takeoff, with all components in their final positions. This preliminary positioning eliminates the complexity of managing flexible lines during the critical takeoff phase.
3Device complexity
If the attack angle of the canopy is fixed, then the structure is simple, but it is impossible to fly at high speed
Solution Approach 1:
The canopy structure transitions from a fixed attack angle to a dynamic, adjustable configuration. The servomotor unit enables real-time modification of the attack angle during flight, allowing the canopy to adapt to different flight conditions and speeds.
Solution Approach 2:
The adjustable attack angle mechanism serves multiple functions: enabling both low-speed and high-speed flight, providing stability during takeoff, and allowing adaptation to various flight conditions. This single mechanism provides universal adaptability across different operational requirements.
4Device complexity
If the drive control unit is located on the bottom, then the structure is simple, but the attack angle of the canopy becomes too large for high-speed flight
Solution Approach 1:
The system transitions from a static drive control unit position to a dynamic configuration where the attack angle can be adjusted independently of the drive control unit location. The servomotor unit enables real-time modification of the canopy's attack angle, decoupling the relationship between drive control unit positioning and flight performance.

Function Achieved in This Case
The solution reduces manufacturing costs, prevents wing folding, eliminates line twisting, and allows for adjustable attack angles, enabling stable takeoff and flight at various speeds, expanding the utility range from low-speed photography to high-speed long-distance travel.
Implementation Method 1
a longitudinal canopy frame that is coupled to the parafoil while having a bent structure to make the parafoil to generate lift force
Implementation Method 2
The servomotor unit may include: a servomotor body; a servomotor body coupler coupled to the servomotor body to accommodate the servomotor body; and a servomotor arm that couples and secures the intersect portion of the horizontal canopy frame and the longitudinal canopy frame

AI summary
A paradrone includes a canopy having a parafoil, a transverse canopy frame coupled to the parafoil to support the parafoil, a longitudinal canopy frame that is coupled to the parafoil while having a bent structure such that the parafoil generates a lift, and at least one parafoil connecting portion for connecting at least one canopy frame among the transverse canopy frame and the longitudinal canopy frame to the parafoil. The paradrone also includes a servomotor portion having a servomotor body and a servomotor arm for coupling and fixing intersecting parts of the transverse canopy frame and the longitudinal canopy frame. The servomotor arm is connected to a servomotor body and rotated in a predetermined direction by driving of the servomotor body to change the angle between the travelling direction of the paradrone fuselage and the transverse and longitudinal canopy frames, thereby changing the angle of attack.
