Rotatable Anchoring Device for Guide Wire Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring devices for guide wires do not provide sufficient options for holding multiple guide wires without interference, particularly when two people need to pass each other, as they lack flexibility in wire guide placement and energy absorption during falls.
Innovation Solution
The anchoring device features rotatable and positionable carriers with wire guides at varying distances from the central axis, allowing for increased flexibility in guide wire placement and energy absorption through energy-absorbing elements like disc springs and deformation sleeves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wire guides are placed at fixed positions on the support, then the structure is simple, but the flexibility for holding multiple guide wires without interference is limited
Solution Approach 1:
The wire guides are made rotatable relative to the support structure, allowing their positions to be dynamically adjusted. This enables flexible placement of multiple guide wires at different angles and positions without requiring a complex reconfigurable structure, as each guide can be independently positioned and locked in place.
Solution Approach 2:
The support structure is divided into multiple independent wire guides that can be individually positioned and rotated. This segmentation allows each guide wire to be placed optimally without interfering with others, while the modular nature keeps the overall structure relatively simple and manageable.
2Area of stationary object
If multiple wire guides are placed close together, then the device size is reduced, but the risk of cable interference increases
Solution Approach 1:
The wire guides are arranged not only in the horizontal plane but also at different vertical heights and angular positions around the support. This three-dimensional arrangement allows multiple guide wires to be placed in close proximity without their cables interfering with each other, as they occupy different spatial dimensions.
Solution Approach 2:
The rotatable wire guides enable dynamic adjustment of cable routing paths. By rotating guides to optimal positions, cables can be directed along separate trajectories that minimize interference, even when guides are positioned close together on the compact support structure.
3Adaptability or versatility
If the support structure is symmetric, then manufacturing is easier, but the adaptability to different mounting orientations is reduced
Solution Approach 1:
The wire guides can be rotated to change their angular parameters and positions relative to the support. This parameter adjustment capability allows the same symmetric support structure to be adapted to various mounting orientations and configurations without requiring different manufactured components for each orientation.
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
This solution enables safe passage of multiple individuals without cable interference and effectively absorbs fall energy, ensuring secure attachment of guide wires on various surfaces like roofs, walls, and ceilings.
Implementation Method 1
an energy-absorbing element (25) is present. The support (13) absorbs the energy of a person fallen. This person is captured with a jerk by the support (13) via the fuse cable (7) and the guide wire (3) and the energy of the fall is absorbed by the energy-absorbing element. This element (25) and the sleeve around this element will deform when a jerk is applied to the support (13) and thereby absorb energy.

AI summary
An anchoring device 1 for the fastening of guide wires 3 on a roof has a base 11 which is provided with a mounting surface, as well as a support 13 attached to the base, and carriers 15 to which wire guides 17 are attached for holding the guide wires. The carriers are rotatably connected to the support and can be fixed in any desired relative position to the support, so that the anchoring device has many possibilities for holding the guide wires. The support 13 has a number of parts 13a-d which are present between the carriers 15, whereby between two adjacent parts of one or more carriers can be clamped. The wire guides 17 are at different distances d1 and d2 from the central axis 9 of the support 13 and are at distances D1, D2 and D3 from each other.
