Bracket Device Locking Nut Reduces Gap Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bracket devices fail to securely attach lightweight wires, such as fiber-optic wires, due to wind whipping and other forces, causing them to dislodge, and often require difficult installation.
Innovation Solution
A bracket device with a retention hook and locking nut system, where the locking nut moves between an unlocked and locked position to reduce the gap width, ensuring the wire is retained within the retention region, preventing dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bracket devices are used to secure lightweight wires, then the device structure is simple, but the wire can be dislodged due to wind whipping and other forces
Solution Approach 1:
The bracket device is divided into distinct functional components: a base for mounting, a retention hook for holding the wire, and a locking mechanism with movable and fixed portions. This segmentation allows each component to perform its specific function effectively, with the locking mechanism providing secure retention while the base ensures stable mounting.
Solution Approach 2:
The locking mechanism incorporates movable and fixed portions that can transition between locked and unlocked states. The movable portion can be shifted to engage or disengage from the fixed portion, dynamically adjusting the retention state of the wire. This dynamic capability allows the device to securely hold wires during operation while enabling easy installation and removal.
2Ease of operation
If traditional bracket devices are used, then the device structure is simple, but the installation process is difficult
Solution Approach 1:
The locking mechanism is designed with movable and fixed portions that can easily transition between engaged and disengaged states. During installation, the movable portion can be readily shifted to the unlocked position, allowing the wire to be inserted, and then shifted to the locked position to secure the wire. This dynamic design simplifies the installation process while maintaining secure retention.
Solution Approach 2:
The base is pre-configured with mounting features and the retention hook is pre-positioned to receive the wire. The locking mechanism is designed so that the movable portion can be easily shifted to the unlocked state before wire insertion, eliminating the need for complex assembly steps during installation.
3Stability of the object's composition
If lightweight wires are used, then the wire flexibility is good, but the wire can jump out of the bracket due to springing action
Solution Approach 1:
The locking mechanism dynamically secures the wire by engaging the movable portion with the fixed portion, creating a stable retention structure that counteracts the wire's springing action. The dynamic locking capability allows the device to maintain firm hold on flexible wires during operation while enabling easy access during installation and maintenance.
Solution Approach 2:
The retention hook and locking mechanism are designed to preemptively counteract the springing action of flexible wires. The hook geometry and locking engagement are configured to resist the wire's tendency to jump out, applying counteracting forces before the wire can dislodge during operation under wind or other loads.

AI summary
A bracket device to secure a tail wire of a drop wire clamp to a structure including a base having a surface. The bracket device further includes a retention hook having a first end, a second end, and retention region defined between the first end and second end. The first end of the retention hook is coupled to the base surface, and the second end of the retention hook is disposed at a predetermined distance from the base surface to define a gap therebetween having a width. The bracket device further includes a locking nut that is cooperatively coupled to the second end of the retention hook and adapted to move between an unlocked position to permit a wire to enter the retention region and a locked position in which a wire is retained by the retention hook in the retention region by a reduction of the gap width.
