Solution Overview

Problem

Existing methods for installing avifauna beacons on overhead electrical cables require discontinuing the electrical supply, are costly, and pose safety risks due to difficulties in accessing cables in challenging terrains and ensuring correct clamp closure by drones.

Innovation Solution

A device comprising a drone, an avifauna beacon, and an installation interface with centering means, actuation system, and presence detectors allows for the secure and continuous attachment of beacons to live cables using a clamp with spring-biased jaws and adjustable components for precise positioning and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If beacons are installed on aerial cables using nacelles or poles, then beacons can be fixed on cables, but access becomes difficult in marshy, hilly, mountainous areas or when lines are above watercourses or lakes

Engineering Contradiction:
Improvebeacon installation capabilityVSAvoidaccess to cables
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces an intermediary device (the beacon with integrated clamp and mounting mechanism) that can be deployed remotely via drone to attach directly to cables. This intermediary solution eliminates the need for physical access platforms (nacelles/poles) by enabling direct cable attachment from aerial position, thus resolving the access difficulty in challenging terrains.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If beacons are installed using helicopters or drones, then access to difficult terrains is improved, but the power to ensure correct clamp closure is insufficient

Engineering Contradiction:
Improveaccess to cablesVSAvoidclamp closure force
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The clamp mechanism incorporates spring-loaded jaws that dynamically adjust and apply continuous closing force to maintain secure cable grip. The spring mechanism provides the necessary force enhancement beyond what a simple drone actuator could deliver, ensuring reliable clamp closure while remaining compatible with drone deployment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs a rapid-deployment mechanism where the drone quickly positions and triggers the clamp closure in a single swift action. This 'rushing through' approach allows the drone to complete the installation task before imbalance or instability can affect the operation, overcoming the drone's limited power and stability constraints.

Inventive Principle:
Principle #21Skipping (Rushing through)

3Reliability

If electric lines are dismantled for beacon installation, then beacons can be securely installed, but electrical supply continuity is disrupted and costs increase

Engineering Contradiction:
Improvebeacon installation securityVSAvoidelectrical supply continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent prepares the clamp and mounting mechanism in advance on the drone platform, with all components pre-positioned and pre-tested. This preliminary preparation allows the beacon to be installed in a single secure attachment operation without requiring cable dismantling, thus maintaining electrical supply continuity while ensuring reliable installation.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If drones are used to press clamps against cables, then beacon installation is enabled, but drone imbalance risk increases

Engineering Contradiction:
Improvebeacon installation capabilityVSAvoiddrone balance
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The drone system incorporates counterbalancing mechanisms or strategically positioned components that offset the weight and force imbalances created during clamp actuation. This anti-weight approach allows the drone to maintain stability while delivering the necessary closing force to secure the beacon clamp on the cable.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
