Removable Jamb System for Building Entryway Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delays in door and frame delivery due to supply-chain or labor issues can leave building entryways exposed, causing damage from elements and increasing theft and vandalism risks, hindering construction timelines and making it difficult for manufacturers to secure jobs with long lead times.
Innovation Solution
A temporary enclosure system comprising removably attachable left and right frame-side jambs, a transom, and temporary panels that secure the entryway until doors can be properly hung, allowing for partial assembly and glazing before door installation, and then easily removable to accommodate the doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If door and frame assembly is delayed due to supply-chain or labor issues, then manufacturing lead time is extended, but building enclosure is compromised and interior is exposed to elements and theft
Solution Approach 1:
The jamb assembly is divided into modular components: a reusable frame-side jamb portion that remains installed in the building, and removable door-side jamb portions that can be temporarily installed and then removed. This segmentation allows the building to be enclosed during manufacturing delays while preserving the ability to install the final door assembly when ready.
Solution Approach 2:
The frame-side jamb portions are installed in advance during the framing process, before the door and complete jamb assembly are ready. This preliminary action provides immediate building enclosure and protection, allowing the door assembly to be manufactured and delivered on its own schedule without delaying the building enclosure.
2Reliability
If temporary enclosure is installed to protect building during lead time, then building security is improved, but permanent door assembly installation becomes more complex
Solution Approach 1:
The jamb is segmented into frame-side and door-side portions with complementary mating features. The frame-side portions are permanently installed and include receiving features that accept the door-side portions. This segmentation simplifies the installation process by allowing separate installation of permanent and temporary components.
Solution Approach 2:
The removable door-side jamb portions serve as intermediary components that temporarily complete the jamb assembly during the lead time period. These intermediaries provide the necessary enclosure and security, and are designed to be easily removed and replaced with the final door assembly components when ready.
3Reliability
If complete jamb assembly is installed before door delivery, then building enclosure is achieved, but flexibility to accommodate door installation is reduced
Solution Approach 1:
The complete jamb assembly is segmented into permanent frame-side portions and removable door-side portions. This allows the permanent portions to provide immediate building enclosure while the removable portions can be easily removed and reconfigured to accommodate the final door assembly installation.
Solution Approach 2:
The jamb assembly transitions from a static complete installation to a dynamic configuration where door-side portions can be removed and reinstalled. This dynamic approach maintains building enclosure during the lead time while providing flexibility for the final door installation when conditions are optimal.

AI summary
An enclosure system for a building includes an entryway for the building defined by opposing left and right frame-side jambs and a frame-side transom extending between the left and right frame-side jambs, and a temporary enclosure system removably installable within the entryway. After removing the temporary enclosure system from the entryway, the enclosure system further includes a left door-side jamb attachable to the left frame-side jamb to form an assembled left jamb, a right door-side jamb attachable to the right frame-side jamb to form an assembled right jamb, and a door-side transom attachable to the frame-side transom to form an assembled transom. One or more doors are hung within the entryway and extend laterally between the assembled left and right jambs and vertically to the assembled transom.
