Polygonal Roller Mount Axle with Asymmetric Holding Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller mounts for conveyer rollers have limited holding effectiveness due to identical positioning hole sizes, leading to detachment under force or vibration, and require two fasteners for assembly, making the process time-consuming.
Innovation Solution
A roller mount design featuring an axle with a polygonal cross section, multiple holding panels with polygonal positioning and securing holes, and a male-female combination mechanism between panels, allowing for secure attachment with a single fastener and enhanced holding capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning holes of the same size are used in the securing board and holding panels, then the structure is simple, but the holding effect is limited and the connecting end of the axle easily detaches under force or vibration
Solution Approach 1:
The positioning holes in different holding panels have different sizes to create localized variations in holding capability. The first positioning hole has a first size while the second positioning hole has a second size different from the first size, allowing each panel to contribute differently to the overall holding effect against detachment forces
Solution Approach 2:
The asymmetric design of positioning holes with different sizes breaks the symmetry of the conventional structure. This asymmetric configuration prevents the axle connecting end from easily detaching by creating uneven distribution of holding forces across the different panels
2Reliability
If two fasteners are used to secure the holding panels, then the connection is secure, but the assembly and disassembly process is time-consuming
Solution Approach 1:
The patent combines the functions of multiple fasteners into a single fastener that can secure multiple holding panels simultaneously. This merged fastening approach maintains connection security while significantly reducing the time required for assembly and disassembly operations
Solution Approach 2:
The single fastener is designed with multi-functionality to secure different holding panels with different positioning hole sizes. The fastener serves multiple purposes: securing the first holding panel with the first positioning hole and the second holding panel with the second positioning hole, eliminating the need for separate fasteners for each panel

AI summary
A roller mount for a roller of a conveyer has an axle, multiple holding panels, and a fastener. The holding panels are mounted around a connecting end of the axle, and each has a positioning hole and a securing hole. The positioning hole has a diameter larger than that of the connecting end of the axle. At least one pair of male-female combination is defined between each pair of adjacent holding panels. A distance between an uppermost one pair of the at least one male-female combination and the positioning hole in one of a corresponding pair of adjacent holding panels is different that between the uppermost pair of male-female combination and the positioning hole in the other of the pair of adjacent holding panels. The fastener is mounted through the aligning securing holes in the holding panels.
