Drone Guard with Tension Adjusting Mechanism for Rotor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial vehicle protection systems, such as those disclosed in JP 6 245 566 B1, focus primarily on rotor protection but lack ease of mountability and portability for the protective member.
Innovation Solution
A protective member for aerial vehicles, comprising support members connected to the vehicle with a flexible member stretched between them, featuring a tension adjusting mechanism to adjust tension and ensure secure mounting, allowing for easy carrying and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective member with rigid structure is used to protect rotors from impact, then protection reliability is improved, but portability and ease of carrying deteriorate
Solution Approach 1:
The patent employs flexible members (such as elastic bands or flexible rods) instead of rigid protective structures. These flexible members can be stretched between support members to form a protective cage around the rotors, providing impact protection while remaining lightweight and easily storable when not in use, thus resolving the contradiction between protection reliability and portability
Solution Approach 2:
The protective member is designed to be dynamically deployable - it can be quickly assembled around the rotors when needed and easily removed or collapsed when not needed. The flexible members allow the structure to adapt its shape and provide protection only when required, maintaining portability while ensuring protection reliability during operation
2Reliability
If a protective member with complex mounting structure is used to ensure secure mounting, then mounting reliability is improved, but ease of mounting deteriorates
Solution Approach 1:
The protective member is divided into separate modular components: support members that attach to the aerial vehicle body, and flexible members that connect the support members. This segmentation allows each component to be independently attached using simple mechanisms, improving ease of mounting while maintaining secure mounting reliability through the coordinated assembly of multiple components
Solution Approach 2:
The support members are designed with pre-formed attachment interfaces (such as clips, hooks, or magnetic attachments) that can be preliminarily prepared and then quickly engaged with the aerial vehicle body. This preliminary preparation of mounting interfaces enables secure mounting without requiring complex assembly procedures during the mounting process
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 solution provides enhanced mountability and portability of the protective member while effectively preventing rotor damage from external impacts, maintaining a strong and flexible structure for impact absorption.
Implementation Method 1
at least one of the plurality of support members has a tension adjusting mechanism that is capable of adjusting a tension applied to the flexible member in a stretching direction, by changing a distance from a center of the body to the distal end portion
