Split Jamb Bracket for Plumb Alignment and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split door jamb systems face challenges in installation accuracy and labor intensity, particularly in masonry and non-masonry structures, where misalignment and damage occur due to construction processes, and require cementaceous filling for rigidity, leading to increased costs and complexity.
Innovation Solution
A split jamb system with a unique bracket design that allows for easy installation, adjustment, and leveling, eliminating the need for cementaceous filling, and enabling installation after wall structure completion, with adaptable trim pieces for varying depths and the ability to be reused without disrupting the wall or finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If split door jamb is installed during construction process, then it provides structural support, but it is subject to being hit or moved out of plumb and square arrangement
Solution Approach 1:
The door jamb is pre-assembled with adjustable brackets and leveling mechanisms before installation, allowing it to be self-leveling and self-aligning once installed, thereby maintaining precision even after construction activities occur around it
Solution Approach 2:
The bracket incorporates adjustable components that allow the door jamb to be dynamically repositioned and re-leveled after initial installation, accommodating movement or misalignment that occurs during construction
2Stability of the object's composition
If cementaceous fill is used to obtain rigidity, then the hollow metal jamb members gain structural stability, but drilling holes becomes complex and expensive
Solution Approach 1:
The cementaceous fill material is completely removed from the system. Instead, the patent uses hollow metal jamb members with internal bracing structures and adjustable brackets that provide rigidity without requiring filling, thereby eliminating the drilling complexity associated with solidified cement
Solution Approach 2:
The patent changes the structural parameters of the jamb members by incorporating internal reinforcement elements and adjustable bracket systems that provide the necessary rigidity through mechanical means rather than through cementaceous filling
3Strength
If split door jamb is installed early in construction, then it provides support during building process, but it requires extensive finishing work to reach jamb members
Solution Approach 1:
The door jamb system is designed with pre-attached trim pieces and finished surfaces that extend to the final installation position, allowing the jamb to be installed early for structural support while eliminating the need for subsequent finishing work to reach the jamb members
4Strength
If traditional mounting brackets are used, then door support is provided, but installation is labor intensive and requires skill for leveling and mounting
Solution Approach 1:
The mounting bracket incorporates adjustable components including sliding mechanisms, telescoping elements, and removable shims that allow installers to dynamically adjust the door jamb's position and level during installation, significantly reducing the skill and labor required compared to traditional fixed brackets
