Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manned/unmanned aerial vehicles are used to observe peripheral situations, then high-altitude observation capability is achieved, but operation preparation time increases and response speed decreases
Solution Approach 1:
The patent extracts the power-driven device from the flying unit, eliminating the need for complex power systems, propellers, and control mechanisms. This simplification removes preparation barriers and enables immediate deployment in emergency situations while maintaining high-altitude observation capability through passive aerodynamic flight.
Solution Approach 2:
The patent employs a disposable, single-use flying unit that is launched and then discarded after completing its observation mission. This eliminates the need for maintenance, recovery, and reuse preparation, allowing rapid replacement and continuous operation without the time-consuming preparation associated with reusable manned or unmanned aerial vehicles.
2Adaptability or versatility
If manned/unmanned aerial vehicles are used for observation, then high-altitude viewing is achieved, but operational restrictions due to peripheral environment occur
Solution Approach 1:
The flying unit is designed to autonomously perform its observation function without human intervention or complex control systems. It launches itself, positions itself using aerodynamic forces, captures images, and returns automatically, eliminating operational restrictions related to pilot requirements, control complexity, and environmental constraints that affect manned or unmanned aerial vehicles.
3Object-affected harmful factors
If manned/unmanned aerial vehicles with power-driven devices are used, then propulsion capability is achieved, but position exposure due to noise occurs
Solution Approach 1:
The patent removes the power-driven device entirely from the flying unit, eliminating the noise source that causes position exposure. The unit relies on passive aerodynamic forces for propulsion and maneuvering, making it completely silent and undetectable by acoustic means, thus preventing position exposure while maintaining sufficient propulsion capability for the observation mission.
4Ease of manufacture
If complex power-driven systems are used in flying units, then propulsion and control capability are improved, but device complexity and maintenance costs increase
Solution Approach 1:
The patent extracts all complex power-driven systems including engines, propellers, batteries, and control mechanisms from the flying unit. This leaves only simple aerodynamic structures and imaging equipment, dramatically reducing device complexity and eliminating maintenance requirements while maintaining adequate propulsion and control through passive aerodynamic design.

Enables rapid, cost-effective, and secure high-altitude observations in emergency situations by eliminating the need for separate power sources and reducing exposure risks, while maintaining a simple structure for low maintenance costs.
Implementation Method 1
automatically generates rotational force by means of drag force applied to the body part when the body part falls so as to decrease a falling velocity of the body part
Implementation Method 2
falls, by its own weight, toward the ground from a position of a top dead point (TDP)
