Door Trim Bracket Shoulder for Precise Reveal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door trim installation systems lack a mechanism for accurate alignment and support of the top piece of door trim with respect to the door frame, leading to misalignment of side pieces during installation.
Innovation Solution
A door trim installation system comprising a right-angle bracket with a support shoulder projecting beyond the door frame, an angled reinforcement structure, and a securing assembly to temporarily secure the bracket to the frame, providing an alignment and support surface for the top piece of door trim.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional door trim installation methods are used without a support structure, then the installation process is simpler, but alignment precision of the top piece with the door frame deteriorates
Solution Approach 1:
The patent introduces a right-angle bracket as an intermediary tool between the installer and the door frame. This bracket includes a support shoulder that temporarily supports the top piece of door trim against the door frame, enabling precise alignment without requiring the installer to manually hold and align the trim piece. The bracket acts as a mediator that transfers the alignment function from the installer's hands to a dedicated alignment device.
Solution Approach 2:
The right-angle bracket is positioned and secured to the door frame before the top piece of door trim is installed. This preliminary positioning creates a pre-established alignment reference (the support shoulder) that guides the placement of the top piece. By performing the alignment preparation in advance, the actual installation of the trim piece becomes a simple placement operation rather than a complex alignment task.
2Productivity
If manual alignment methods are used for door trim installation, then fewer tools are required, but installation time and labor intensity increase
Solution Approach 1:
The right-angle bracket serves as a mechanical intermediary that handles the difficult alignment and holding functions. Instead of the installer manually positioning and holding the top piece against the frame, the bracket does this work mechanically. The installer simply needs to place the top piece on the support shoulder, significantly reducing labor intensity and improving ease of operation.
Solution Approach 2:
The support shoulder of the right-angle bracket is designed to automatically maintain the correct spacing (reveal) between the top piece of door trim and the door frame. Once the bracket is positioned correctly on the frame, the support shoulder self-maintains the proper alignment and spacing without requiring continuous manual adjustment by the installer, enabling the system to serve itself in maintaining alignment.
3Reliability
If the top piece of door trim is installed without proper support, then installation is faster, but subsequent side piece alignment becomes difficult
Solution Approach 1:
The right-angle bracket is installed and secured to the door frame before the top piece of door trim is placed. This preliminary action establishes a reliable alignment reference that ensures the top piece will be correctly positioned. By preparing the alignment structure in advance, the method prevents alignment problems that would otherwise require time-consuming corrections during or after installation of all trim pieces.
Solution Approach 2:
The right-angle bracket acts as a temporary intermediary structure that ensures reliable alignment of the top piece during installation. This intermediary device maintains the correct spatial relationship between the top piece and the door frame, which in turn provides a reference for aligning the side pieces. The bracket is removed after serving its alignment purpose, having successfully transferred the alignment function to the completed trim assembly.

AI summary
A door trim installation system includes a right-angle bracket that includes a first leg and a second leg, an angled reinforcement structure attached to and reinforcing the first leg and the second leg, and a securing assembly to temporarily secure the bracket to a door frame. Each of the first and second legs includes an outer surface abuttable against an interior surface of a corner portion of a door frame. The first leg includes a support shoulder designed to project out beyond a door frame and upwardly over a reveal to provide an alignment and support surface for a top piece of door trim or moulding to be installed.
