Adjustable Pin Mounting Bracket for Rack Hole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting brackets face installation difficulties due to non-adjustable pins that cannot match the varying hole distances in equipment racks, leading to significant resistance and incomplete installation, especially when there are large tolerances between holes.
Innovation Solution
A mounting bracket with a pin assembly comprising a pin, protrusion, and fixing member, where the protrusion is movable within an elongate hole of the end plate, allowing transverse adjustment of the pin for better alignment with equipment rack holes, ensuring easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the pins on the mounting bracket are engaged with the holes in the vertical support columns with only very small gap, then the structural stability is improved, but the ease of operation deteriorates because the pins cannot be adjusted laterally to match varying hole distances
Solution Approach 1:
The pin is made movable within the elongate hole of the end plate, allowing it to adjust its position laterally. The protrusion can slide within the elongate hole, enabling the pin to move transversely to match varying hole distances on different equipment racks, thus resolving the contradiction between structural stability and ease of installation
2Device complexity
If the mounting bracket uses fixed pins without adjustment capability, then the device complexity is reduced, but the adaptability deteriorates because the bracket cannot accommodate varying hole distances and tolerances
Solution Approach 1:
The pin assembly incorporates a movable pin that can slide within the elongate hole, providing adjustment capability to accommodate varying hole distances and tolerances on equipment racks, thus improving adaptability without significantly increasing device complexity
Solution Approach 2:
The protrusion acts as an intermediary element between the pin and the end plate, allowing the pin to move independently within the elongate hole while maintaining connection to the mounting bracket, enabling adaptation to different hole positions
3Manufacturing precision
If the pins are positioned with very small gap for precise engagement, then the manufacturing precision is improved, but the ease of operation worsens because any tolerance variation prevents proper installation
Solution Approach 1:
The pin is designed to be movable within the elongate hole, allowing it to adjust its position to compensate for tolerance variations in hole distances on equipment racks. This dynamic adjustment capability maintains precise engagement while facilitating easier installation despite manufacturing tolerances

AI summary
A mounting bracket includes an end plate perpendicularly extending from a side plate and having an elongate hole. A pin assembly includes a pin, a protrusion and a fixing member, wherein the pin is connected to the protrusion and contacts the end plate. The protrusion is located in and movable in the elongate hole. The thickness of the protrusion is larger than that of the end plate. The fixing member includes a head and a shank extending from the head. The shank connects the pin and the protrusion. By this arrangement, the fixing member and the pin clamps the protrusion to be movably engaged with the elongate hole. The pin is adjustably moved in the elongate hole by the protrusion in the elongate hole of the end plate.
