Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If energy storage devices with higher energy density are used, then electrical flight performance is improved, but currently such devices are not yet available
Solution Approach 1:
The base body is divided into multiple segments (first segment, second segment, third segment) with each segment capable of receiving energy storage devices. This modular segmentation allows flexible configuration of energy storage capacity while maintaining structural integrity and enabling incremental upgrades as higher density devices become available.
2Weight of moving object
If fiber-reinforced composites such as CFRP and GFRP are used to make multicopters lightweight, then flight performance is improved, but manufacturing cost increases and environmental damage occurs due to difficulty in recycling
Solution Approach 1:
The patent employs composite material construction for the base body segments, utilizing materials that balance lightweight properties with manufacturability and recyclability. The segmented design allows each component to be optimized for its specific function while maintaining overall structural efficiency.
3Use of energy by moving object
If the area around the rotor units is kept unobstructed for efficient airflow, then rotor efficiency is improved, but space for mounting energy storage devices is reduced
Solution Approach 1:
Energy storage devices are positioned in the vertical dimension within the base body segments, below the rotor units. This vertical arrangement preserves the horizontal clearance around rotors for optimal airflow while utilizing the vertical space within the base body for energy storage capacity.
4Stability of the object's composition
If the main mass of the multicopter is located centrally, then flight stability is improved and energy consumption is reduced, but access for maintenance becomes more difficult
Solution Approach 1:
The base body is segmented into multiple accessible sections (first segment, second segment, third segment) that can be independently opened or accessed. This segmentation maintains central mass distribution for flight stability while providing multiple access points for maintenance operations.
5Ease of repair
If a modular design with interchangeable energy storage units is implemented, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The base body is divided into distinct segments (first segment, second segment, third segment) with defined receiving devices for energy storage devices. This segmentation creates a modular architecture that simplifies maintenance operations while the standardized receiving device design across segments reduces overall system complexity.
Solution Approach 2:
Multiple segments are equipped with similar receiving device structures, creating a universal interface for energy storage devices throughout the base body. This universality simplifies maintenance procedures and reduces the variety of components that must be managed, offsetting the apparent complexity with standardization.
