Cable Loop Box with Separate Angle Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rope loop boxes are complex and costly to manufacture, with difficult assembly processes due to precisely matched angle brackets and sealing plugs, making it cumbersome to install and align angled rope loops within the boxes, especially when integrating with formwork for concrete pouring.
Innovation Solution
The angle bracket is designed as a separate, movable part within the housing, allowing for easier insertion and alignment of the rope eyelet, with a plug independent of the angle bracket to close the opening, simplifying assembly and reducing manufacturing costs by accommodating various box cross-sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the angle bracket and sealing plug are precisely matched and designed to fit together, then the sealing performance and structural integrity are improved, but the manufacturing complexity and assembly difficulty increase significantly
Solution Approach 1:
The invention separates the angle bracket from the sealing plug, making them independent components. The angle bracket serves as a guide for the rope loop while the sealing plug independently seals the opening. This segmentation eliminates the need for precise matching between these two components, reducing assembly complexity while maintaining sealing performance through the dedicated sealing function of the plug.
2Stability of the object's composition
If the angle bracket is integrated with the housing as a single component, then the structural integrity is improved, but the adaptability to different box cross-sections decreases
Solution Approach 1:
The angle bracket is designed as a separate, universal component that can be used with housing openings of various cross-sections. Its independent design allows it to function as a rope loop guide across different box configurations without requiring custom integration for each housing type, thereby enhancing versatility while maintaining structural integrity through proper mounting.
3Device complexity
If the opening in the housing is closed by a plug integrated with the angle bracket, then the number of components is reduced, but the ease of assembly and alignment corrections post-installation deteriorates
Solution Approach 1:
The invention divides the closing function into two independent elements: the angle bracket that guides the rope loop and the sealing plug that closes the opening. This segmentation allows each component to be assembled independently and facilitates post-installation alignment corrections, as the plug can be adjusted or removed separately from the angle bracket without affecting the rope loop guidance function.
4Object-affected harmful factors
If a tight-fitting cover is attached to the cable loop box to prevent concrete penetration, then the protection against concrete infiltration is improved, but the assembly complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the sealing function from a complex tight-fitting cover system and implements it through a simple sealing plug that closes the opening after the angle bracket is in place. This approach provides adequate protection against concrete infiltration during formwork filling while significantly reducing assembly complexity and manufacturing cost compared to a tight-fitting cover system.

AI summary
The present invention relates to a cable loop box with a cable loop (20), comprising an elongated, tubular housing (10), wherein at least one of the ends of the housing is open, into said open end a cable eyelet (21), which is held in a position substantially deflected by 90° by a bracket support (30), can be inserted, said bracket support being separate from the housing (10), wherein the open end of the cable eyelet or the deflected ends (22) of the cable loop (20) protrude out from the open end (12) or from an opening (12a) of a bottom side (14) of the housing next to the end (12). According to the invention, it is proposed that the bracket support is a separate part separate from an end plug (15), said support able to be inserted into the housing and that the free cross section of the end not subject to load from the cable loop and the bracket support, and optionally a lateral housing opening proximate thereto, is sealed by the plug.
