Spool Rack Strut with Upward Pocket for Axle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spool-holding racks lack an efficient and easy-to-use strut system for supporting spools with windable materials, particularly in facilitating the loading and positioning of spools within the rack, and require a more robust yet uncomplicated axle assembly for reliable operation.
Innovation Solution
A strut system with elongated beams having upwardly-opening pockets and abutment surfaces for guiding and securing protruding spool ends, combined with a spool-holding axle assembly featuring rotating bearing assemblies to accommodate the spool's axis, ensuring secure and easy spool positioning and operation within the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple rod or axle is used to support the spool, then the structure is uncomplicated, but the ease of positioning and securing the spool is insufficient
Solution Approach 1:
The strut is divided into functional segments: the elongated beam for structural support, the pocket for spool end reception, and the abutment surface for positioning guidance. This segmentation allows each component to perform its specific function efficiently without over-complicating the overall structure.
Solution Approach 2:
The pocket acts as an intermediary element between the spool end and the strut beam. It facilitates the positioning and securing of the spool by providing a dedicated receptacle that guides the spool end into place, thereby improving ease of operation without requiring complex external mechanisms.
2Reliability
If traditional struts without pockets are used, then the structure is simpler, but the reliability of spool support is insufficient
Solution Approach 1:
The pocket is pre-formed as an integral part of the strut structure, ready to receive the spool end before the spool is actually positioned. This preliminary preparation ensures that the spool end has a predetermined, reliable path and location for placement, thereby enhancing support reliability without adding complex assembly steps.
Solution Approach 2:
The pocket structure is designed to automatically guide and secure the spool end through its geometric configuration alone, without requiring additional fastening mechanisms or external assistance. The pocket's shape and position inherently provide the necessary support and alignment, making the system self-sufficient and reliable.
3Ease of operation
If multiple components are added to facilitate spool loading, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The bearing assemblies are merged with the axle to form an integrated axle assembly. This combination allows the bearings to be pre-positioned and secured on the axle, simplifying the overall loading process by reducing the number of separate components that need to be handled and assembled during spool installation.
Solution Approach 2:
The axle assembly is designed to perform multiple functions: it provides rotational support through the bearings, positions the spool correctly via the interaction with the pocket and abutment surface, and maintains structural integrity. This multi-functionality reduces the need for separate dedicated components, thereby improving ease of operation without proportionally increasing complexity.

AI summary
Each of a pair of spool-supporting struts for a spool-holding rack having two pairs of vertical posts between which the struts are mounted utilizes an axle assembly having rotatable end portions for resting upon the struts and a beam having two opposite end portions. The beam includes an upwardly-opening pocket which is adapted to accept a rotatable end portion of the axle assembly directed downwardly therein, and there is associated with each end portion of the beam a platen portion which is positionable outboard of the pair of vertical posts. In addition, an abutment surface is associated with the upwardly-opening pocket for aiding in the locating of an end portion of the axle assembly in vertical registry with the upwardly-opening pocket, and the upwardly-opening pocket includes a pair of spool-centering guide plates along the side opening thereof.
