Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying objects face challenges in increasing cruising range and fuel efficiency, especially when transporting larger and heavier loads, and require improvements in flight efficiency over ocean or mountainous areas where external power is unavailable.
Innovation Solution
A flying object design with a loading part that tilts backward in the forward and backward direction during landing or hovering, positioning the center of the loading part relative to the airframe to optimize lift generation and reduce drag, and using a streamlined shape to enhance fuel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the size and weight of goods carried in a single flight are increased, then the load capacity is improved, but drag and motor addition increase leading to decreased fuel efficiency
Solution Approach 1:
The loading part is designed to be tiltable relative to the airframe, allowing the center of gravity to be adjusted forward or backward. This dynamic positioning optimizes the weight distribution and reduces drag during flight, improving fuel efficiency while maintaining increased load capacity
Solution Approach 2:
The attitude angle of the loading part can be changed to optimize aerodynamic characteristics. By adjusting the tilt angle of the loading part, the drag coefficient is reduced, allowing larger loads to be carried with improved fuel efficiency
2Use of energy by moving object
If the loading part is positioned to optimize lift generation, then fuel efficiency is improved, but the complexity of positioning and attachment increases
Solution Approach 1:
The loading part is equipped with a tilting mechanism that allows adjustment of its attitude angle relative to the airframe. This enables the system to optimize lift generation and fuel efficiency dynamically during flight operations
Solution Approach 2:
The loading part is designed as a separate, detachable module from the airframe. This segmentation allows for simplified attachment and detachment operations while maintaining the ability to optimize positioning for fuel efficiency
