Pivot Mount Block Bearing Assembly for Multi-Axis Door Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hardware for mounted structures like ballistic doors cannot withstand the pressure and does not allow for efficient adjustments, especially after installation, due to misalignment and substructure variations, making adjustments time-consuming, labor-intensive, and expensive.
Innovation Solution
An adjustable mounting system featuring a pivot mount block with a bearing and pivot bolt configuration that allows for multi-axis adjustments, including x-axis, y-axis, z-axis, and rotational adjustments, using a pivot bolt with a disk feature and a pivot height-adjustment nut, enabling easy and economical adjustments without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hardware is used for ballistic doors, then the door can be installed, but it cannot withstand the pressure (800-1000 psi) and cannot be adjusted for misalignment or substructure variations
Solution Approach 1:
The hinge assembly incorporates adjustable components including a height adjustment mechanism with a slot and adjusting screw, and a pivot adjustment mechanism with a slot and adjusting screw, allowing the hinge to dynamically adapt to misalignment and substructure variations while maintaining structural integrity under pressure
Solution Approach 2:
The hinge assembly is divided into separate adjustable components (mounting plate, hinge body, adjustment mechanisms) that can be independently adjusted along multiple axes to compensate for installation variations while collectively withstanding the door's weight and pressure
2Ease of operation
If adjustments are made to mounted structures after installation using existing hardware, then alignment can be corrected, but the process requires disassembly and removal of the door, making it time-consuming and labor-intensive
Solution Approach 1:
The hinge assembly includes integrated adjustment mechanisms with accessible adjusting screws and slots that allow operators to make multi-axis adjustments (height, horizontal position, pivot alignment) directly on the installed door without disassembly, enabling the system to self-adjust to proper alignment
Solution Approach 2:
The hinge assembly is pre-configured with adjustment mechanisms and slots during manufacturing, allowing for easy field adjustments to be made later without requiring disassembly or special tools, thus saving time and labor during installation and maintenance
3Ease of manufacture
If existing hardware is used for ballistic doors, then installation can proceed, but adjustments require costly and labor-intensive reinstallation processes
Solution Approach 1:
The hinge assembly serves multiple functions: it withstands the door's weight and pressure, provides multi-axis adjustment capability, and allows for field adjustments without disassembly, eliminating the need for costly reinstallation processes and reducing both initial installation complexity and long-term maintenance costs

AI summary
An adjustment system comprising: a pivot mount block comprising an aperture configured to allow an upper portion of the pivot bolt to pass through the pivot mount block, the aperture having a lower radius greater than an upper radius so as to form ledge feature; and a bearing inserted in the aperture, wherein the ledge and a lower portion of the bearing is configured to rest on a pivot height-adjustment nut that is on the upper portion of the pivot bolt, or on a second bearing that rests on the pivot-height-adjustment nut on the upper portion of the pivot bolt, and wherein the upper portion of the pivot bolt extends out of the pivot mount block to pivotally support a frame that is mounted on the pivot mount block.
