Adjusting Base for Door Closer with Segmented Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door closer adjusting bases face challenges in convenient and efficient adjustment due to poor installation precision, leading to the door closer's inability to drive the door back to a predetermined closed position.
Innovation Solution
An adjusting base with a fixing member, an adjustable adjusting member, and multiple adjusting units that allow for precise adjustment of the relative position and angle between the fixing member and the adjusting member, enabling easier alignment and installation of the door closer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the door closer is fixed to a surface through a mounting base, then the door closer can be installed, but poor installation precision prevents the door from returning to the predetermined closed position
Solution Approach 1:
The mounting base is divided into a fixing member (fixed to the surface) and an adjusting member (connected to the door closer), which can be relatively adjusted. This segmentation allows the fixing member to provide stable installation while the adjusting member enables precision adjustment of the door closer position and angle, thereby improving both installation precision and door return function reliability.
2Manufacturing precision
If the user repeatedly adjusts the position of the mounting base to re-mount the door closer, then the installation precision can be improved, but the adjustment process becomes time-consuming and inefficient
Solution Approach 1:
The adjusting member is designed with movable adjusting units that can be easily repositioned along the fixing member. This dynamic design allows the user to quickly adjust the door closer position and angle by simply moving the adjusting units, eliminating the need for repeated disassembly and reassembly, thereby significantly reducing adjustment time while achieving precise installation.
3Ease of operation
If the adjusting member is fixed relative to the fixing member, then the structure is simple, but the door closer position and angle cannot be adjusted
Solution Approach 1:
The adjusting unit is designed with a universal structure that combines multiple functions: it serves as both a positioning element and an adjustment mechanism. The adjusting unit can be positioned at different locations on the fixing member and fixed in various orientations, providing both position adjustment and angle adjustment capabilities. This multi-functional design achieves high adjustability without significantly increasing structural complexity.

AI summary
An adjusting base (100, 200, 300) for door closer (10) includes a fixing member (110, 310), an adjusting member (120, 320), and at least one adjusting unit (130, 140, 330, 340) . An upper surface of the fixing member (110, 310) is arranged with at least one protrusion (114, 116, 314, 316). The adjusting member (120, 320) is arranged on the upper surface of the fixing member (110, 310) in an adjustable manner, and configured to be connected to a door closer (10). The adjusting member (120, 320) is formed with at least one adjusting hole (124, 126, 324, 326) for receiving the at least one protrusion (114, 116, 314, 316). The at least one adjusting unit (130, 140, 330, 340) is movably arranged on the adjusting member (120, 320) and configured to adjust a relative position between the adjusting member (120, 320) and the fixing member (110, 310).
