Adjustable H-Beam Anchoring with Movable Restricting Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anchoring devices for connecting safety belts to H-beams require multiple sizes due to fixed notch positions, leading to high manufacturing and storage costs due to the non-uniform widths of H-beam flanges.
Innovation Solution
A modular anchoring device with a single-sized track bar and adjustable restricting members with protrusions, allowing the locking portion to resist protrusions at different positions, enabling the device to fit various H-beam sizes without needing multiple device sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed notch positions are used on the track bar, then the locking mechanism is simple and reliable, but the device must be manufactured in multiple sizes to fit different H-beam flange widths
Solution Approach 1:
The restricting members are made movable along the track bar, allowing their positions to be dynamically adjusted. This enables a single track bar design to accommodate various H-beam flange widths by repositioning the restricting members, eliminating the need for multiple fixed-size track bars while maintaining reliable locking when positioned correctly
Solution Approach 2:
The anchoring device is divided into separable components: the track bar and multiple restricting members. This segmentation allows the restricting members to be independently positioned and adjusted along the track bar, providing flexibility to adapt to different H-beam sizes while keeping the track bar design standardized
2Adaptability or versatility
If multiple sizes of anchoring devices are manufactured to fit different H-beam sizes, then the device fits various H-beams, but the manufacturing cost and storage cost increase
Solution Approach 1:
A single standardized track bar design serves multiple functions by accommodating different H-beam flange widths through adjustable restricting members. This universal design eliminates the need to manufacture and store multiple sizes of track bars, reducing both manufacturing complexity and inventory requirements while maintaining the ability to fit various H-beam sizes
3Device complexity
If the locking portion is fixed in position, then the structure is simple, but the device cannot be adjusted to different positions on the track bar
Solution Approach 1:
The locking mechanism is designed to be dynamically adjustable. The locking portion can be repositioned along the track bar by moving the restricting members, allowing the same simple locking structure to function at different positions. This maintains structural simplicity while enabling adaptability to different H-beam configurations

AI summary
An anchoring device includes a track bar, a restricting member, and a locking device, wherein the track bar has a receiving groove. The restricting member is put into the receiving groove through open ends of the receiving groove. A width between a section of walls of the receiving groove and a width of a portion of the restricting member is greater than a width of a mouth of the receiving groove. The locking device includes a main body wherein a locking portion is disposed on the main body and is manipulatable to move between a first position and a second position. The main body slidably fits around the track bar. When the locking portion in the second position, the main body could slide to fit a flange of a fixture. After that, returns the locking portion back to the first position to fix the main body on the track bar.
