Rotating Hanging Ring Fixing Device for High-Altitude Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety fixing devices for high-altitude operations are inefficient and restrictive due to their non-rotatable design, causing the safety belt to wind around the fixing device and limiting worker mobility.
Innovation Solution
A fixing device with a connecting member, first and second pivotable fixing plates, and a rotatable hanging ring, allowing the safety belt to rotate freely and preventing winding, while providing a stable and secure attachment point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a non-rotatable ring is used for connecting the safety belt, then the fixing device provides a stable attachment point, but the safety belt winds around the fixing device when the worker moves, limiting worker mobility
Solution Approach 1:
The patent applies the dynamics principle by making the hanging ring rotatable instead of fixed. This allows the ring to dynamically adjust its orientation as the worker moves, preventing the safety belt from winding around the fixing device while maintaining a stable attachment point. The rotatable mechanism enables the system to adapt to changing worker positions without compromising fixing reliability.
2Ease of operation
If a rotatable hanging ring is used, then the safety belt does not wind around the fixing device and worker mobility is improved, but the device complexity increases
Solution Approach 1:
The rotatable hanging ring introduces dynamic capability to the fixing device, allowing it to adapt to worker movement. This dynamic feature prevents safety belt winding and enhances worker mobility while adding manageable complexity to the device structure.
Solution Approach 2:
The fixing device is segmented into distinct functional components: the connecting member with base and bars, the pivotable fixing plates with sleeves, and the rotatable hanging ring. This segmentation allows each component to perform its specific function independently, making the overall device easier to manufacture, assemble, and maintain despite the added rotational capability.
3Adaptability or versatility
If the first and second fixing plates are made pivotable, then the fixing device can adapt to different installation angles and positions, but the manufacturing precision requirements increase
Solution Approach 1:
The fixing plates are designed with pivotable connections that allow them to rotate and adjust to different installation angles. This dynamic capability provides versatility in installation while the pivot mechanism itself (with sleeves fitting around bars) ensures sufficient precision through mechanical guidance.
Solution Approach 2:
The sleeves of the fixing plates are designed to fit around the bars of the connecting member, creating a nested structure. This nesting arrangement provides both the pivotability needed for angle adjustment and the precision required for proper alignment, as the sleeves guide the bars during assembly and operation.

AI summary
A fixing device adapted to be fixed on a structure is disclosed, which includes a connecting member, a first fixing plate, a second fixing plate, and a hanging ring. The connecting member has a base, a first bar, a second bar, and a third bar. The first bar and the second bar are respectively engaged with two sides of the base. The third bar is engaged with the base. The first and the second fixing plates respectively have a body adapted to be fixed on the structure, and two sleeves respectively fit around the first bar and the second bar, whereby the first and the second fixing plates are pivotable relative to the connecting member. The hanging ring is engaged with the third bar in a rotatable manner. Whereby, the first and the second fixing plates could be engaged with the structure to provide a firm supporting point.
