L-Shaped Door Frame Protective Device with Guide Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-hung door assemblies face damage during shipping and storage due to manual assembly errors and lack of effective protective devices, which can compromise joint integrity and increase installation costs and time.
Innovation Solution
A protective support device with a body portion and adjoining flange portion, featuring guide slots and ramped ends, is designed to attach to the bottom of door frame members for protection during transport and storage, ensuring proper fastener placement and easy removal before installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual assembly without guides is used, then assembly process is simple, but fastener location accuracy deteriorates compromising joint integrity
Solution Approach 1:
The patent introduces guide members as intermediary components that facilitate fastener placement. These guides are temporarily attached to frame members during assembly and provide precise positioning for fasteners, eliminating the need for complex permanent fixtures while ensuring accurate fastener location and joint integrity.
2Object-affected harmful factors
If permanently attached protective structures are used, then protection during shipping is improved, but installation time and complexity worsen
Solution Approach 1:
The patent employs dynamically configurable protective devices that can be temporarily attached during shipping and then easily removed during installation. The guides and protective components are designed to be non-permanently attached, allowing for quick attachment and removal without compromising the structural integrity of the door assembly or requiring excessive installation time.
3Object-affected harmful factors
If conventional protective strips are used, then some protection is provided, but proper component placement assistance is lost
Solution Approach 1:
The patent creates multi-functional components that simultaneously provide protection and guidance. The guide members serve dual purposes: protecting the frame members during handling and providing precise positioning guidance for fasteners during assembly. This eliminates the need for separate protective strips and placement aids, combining both functions into integrated components.
4Adaptability or versatility
If multiple relocations and storage are required, then distribution flexibility is improved, but damage risk to bottom components worsens
Solution Approach 1:
The patent implements protective devices that are attached beforehand to vulnerable bottom components of door assemblies. These protective elements, including guides and cushioning members, are positioned in advance to prevent damage during multiple relocations, handling, and storage operations, allowing the assembly to be distributed flexibly without compromising component integrity.

AI summary
A protective device and method for protection of a door frame member and/or door assembly. The protective device may include a body portion and an adjoining flange portion. The body portion may include a free side and a corner side running parallel to each other and may form an L-shaped device. The flange may include guide slot openings for placement of a fastener through the openings. The body portion may have a substantially planar top and a curved bottom with reduced portions forming attachment areas for securing the protective device removably to a door assembly.
