Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional drone configurations are used, then the structure is simple, but the traveling range and endurance are limited
Solution Approach 1:
The aircraft is divided into modular components including a body, detachable pod, main wings, secondary wings, and linear supports. This segmentation allows for optimized design of each component while maintaining overall system performance for extended endurance operations.
Solution Approach 2:
The patent introduces a vertical dimension to the propeller arrangement with tail-top propellers positioned at a higher horizontal plane than the lifting propellers on linear supports. This three-dimensional propeller configuration optimizes airflow and reduces interference, contributing to improved endurance.
2Adaptability or versatility
If lifting capacity is increased to carry people and cargo, then transport capability improves, but energy consumption increases
Solution Approach 1:
The aircraft features a universal design with a detachable pod that can function as either a passenger pod or cargo pod. The same aircraft structure and propulsion system handle both passenger and cargo transport, optimizing energy efficiency while maintaining versatility in transport capability.
Solution Approach 2:
The aircraft employs dynamically adjustable propeller configurations with multiple lifting propellers on linear supports and tail-top propellers that can be independently controlled. This dynamic adjustment allows optimal energy distribution based on payload requirements, reducing overall energy consumption.
3Force
If propeller size is increased to improve lift, then lifting capacity improves, but the propellers interfere with each other's airflow
Solution Approach 1:
The patent arranges propellers in multiple horizontal planes vertically, with tail-top propellers positioned higher than lifting propellers on linear supports. This vertical stacking in three-dimensional space allows larger propeller radii while maintaining sufficient clearance to minimize airflow interference and energy loss.
Solution Approach 2:
The overlapping propeller configuration creates a nested arrangement where the rotational paths of propellers at different heights partially overlap but do not interfere significantly. This nested structure maximizes lifting capacity while minimizing the harmful effects of propeller interaction.
