Flying Machine Rotor Wire Entanglement Prevention via Protective Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying machines with rotor blades face entanglement issues with connecting wires, particularly when the external device is positioned above or alongside the flying machine, as the wires can become tangled with the rotor blades during operation.
Innovation Solution
Incorporating a pipe-shaped protective member that rotates orthogonally to the rotor blades, with the connecting wire passing through its inner portion to connect the flying machine body and external device, ensuring the wire remains distanced from the rotor blades and preventing entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting wire is positioned outside the rotor blade rotation area, then wire entanglement with rotor blades is prevented, but the device structure becomes more complex and occupies more space
Solution Approach 1:
The connecting wire is nested within the hollow interior of the protective member, which itself is positioned within or around the rotor blade assembly. This nested configuration allows the wire to be protected from entanglement while maintaining a compact overall structure that does not significantly increase device complexity or space occupation.
Solution Approach 2:
The protective member acts as an intermediary structure between the connecting wire and the rotor blades. It provides a physical barrier that prevents direct contact between the wire and rotating blades, thereby preventing entanglement without requiring the wire itself to be routed through complex pathways or requiring major structural modifications to the flying machine.
2Reliability
If the protective member is positioned to protect the wire, then wire entanglement is suppressed, but the flying machine's overall size increases
Solution Approach 1:
The protective member is implemented as a thin-walled hollow structure that provides adequate protection for the connecting wire while occupying minimal volume. The thin-film-like protective barrier suffices to prevent wire entanglement without significantly increasing the flying machine's overall size or weight.
Solution Approach 2:
The protective member utilizes the vertical or radial dimension by positioning itself in the rotation area of the rotor blades, allowing the wire to pass through its hollow interior. This dimensional arrangement protects the wire without requiring horizontal expansion of the device, thereby maintaining a compact footprint.
3Reliability
If the connecting wire passes through the protective member's hollow interior, then wire entanglement is prevented, but manufacturing complexity increases
Solution Approach 1:
The hollow interior of the protective member is pre-formed during manufacturing, creating a ready-made conduit for the connecting wire. This preliminary preparation eliminates the need for complex post-assembly routing or modification, allowing the wire to be simply inserted or routed through the existing hollow space, thereby maintaining ease of assembly.
Solution Approach 2:
The protective member serves multiple functions simultaneously: it provides structural support, acts as a protective barrier against wire entanglement, and provides a built-in conduit for the connecting wire. This multi-functionality reduces the need for separate components and simplifies the overall manufacturing process compared to designs requiring dedicated wire routing structures.

AI summary
A flying machine includes: a flying machine body that includes a rotor blade; a protective member that forms a frame shape inside which the rotor blade is disposed, that is rotatably fixed to both end portions of the flying machine body, and that is pipe shaped; and a connecting wire that passes through an inner portion of the protective member to connect the flying machine body and an external device together.
