Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective member is composed of a large number of plastic pipes and joints assembled in a complicated manner, then the protection function is improved, but the mountability and portability deteriorate
Solution Approach 1:
The protective member is divided into a modular structure consisting of multiple identical or similar supporter units. Each supporter unit is a self-contained module that can be independently assembled and detached, transforming the complicated monolithic structure into simple repeatable units that maintain protection functionality while improving ease of assembly and disassembly
Solution Approach 2:
The protective member is designed with detachable supporters that can be easily attached and detached from the aerial vehicle. This dynamic configuration allows the protective member to be quickly deployed when needed and easily removed when not in use, significantly improving mountability and portability while maintaining the protection function during flight operations
2Reliability
If the protective member is designed without considering detachment, then the protection function is maintained, but the portability deteriorates
Solution Approach 1:
The protective member is segmented into detachable supporter units that can be separated from the aerial vehicle. This segmentation enables the protective member to be easily transported separately from the aerial vehicle, improving portability while maintaining the integrity and protection function when assembled
Solution Approach 2:
The protective member is designed to be temporarily attached and detached based on flight requirements. The supporters can be easily removed and stored or transported separately when not in use, enhancing portability and adaptability while ensuring the protection function is available when needed
3Adaptability or versatility
If the protective member is frequently attached and detached, then the portability is improved, but the connection reliability deteriorates
Solution Approach 1:
The supporters are pre-designed with specific mounting structures and connection interfaces that ensure proper alignment and secure attachment. This preliminary design of the connection mechanism ensures that even with frequent attachment and detachment, the connection reliability remains high due to the built-in alignment guides and secure fastening features
Solution Approach 2:
The system includes a mounting state determiner that detects whether the protective member is properly mounted by sensing the support state. This feedback mechanism provides real-time verification of proper connection, alerting users to any improper attachment before flight, thereby maintaining connection reliability even with frequent assembly and disassembly operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures reliable mounting of the protective member, preventing rotor damage and enhancing flight safety by accurately determining and maintaining suitable support states, thus allowing for easy detachment and reattachment without compromising performance.
Implementation Method 1
each of the plurality of supporters has a strain sensor that detects deformation of the extension part caused by tension applied to the protective member
