Adjustable Door Support for Accurate Gap Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing door slabs are challenging for DIY enthusiasts due to the difficulty in accurately determining the door gap and supporting the replacement slab at the correct height, requiring significant skill and effort, and often result in increased costs and cumbersome installation processes.
Innovation Solution
An adjustable door support system that measures and replicates the door gap between the door slab and the floor, using a frame member and tie devices to hold the replacement slab at the same height, facilitating accurate installation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional door replacement methods are used, then the door slab can be replaced, but the process requires high DIY skill and considerable time and effort
Solution Approach 1:
The patent introduces a door gap measuring tool and support system as intermediary devices that simplify the door replacement process. The measuring tool with adjustable arms and measurement scale provides an intermediate step to accurately determine the door gap, while the support system acts as a mediator to hold the replacement door slab at the correct height, making the installation accessible to DIY enthusiasts without requiring professional expertise
Solution Approach 2:
The patent applies preliminary action by having the installer measure and record the door gap from the existing door before removing it. The measuring tool is configured in advance to capture this dimension, and the support system is prepared beforehand to replicate this measurement, allowing the replacement door to be installed at the correct height without requiring complex adjustments during installation
2Ease of operation
If a pre-hung door unit is used, then installation is simpler, but the entire frame must be removed and reinstalled, increasing cost and effort
Solution Approach 1:
The patent extracts only the necessary function of the pre-hung door system - maintaining the correct door gap - while eliminating the need to remove and reinstall the entire door frame. The measuring tool extracts the door gap dimension from the existing installation, and the support system extracts the height-setting function, allowing the door slab to be replaced independently without disturbing the frame
Solution Approach 2:
The patent segments the door replacement process into independent steps: measuring the door gap with the adjustable tool, removing only the door slab (not the frame), supporting the replacement slab at the measured height, and installing hinges. This segmentation allows the frame to remain in place while still achieving proper door alignment, reducing overall complexity
3Adaptability or versatility
If the replacement door slab is lifted into place manually, then no additional equipment is needed, but the process becomes awkward and difficult without two people
Solution Approach 1:
The support system acts as a mechanical intermediary that takes the weight of the replacement door slab off the installers. The adjustable support device with its base plate and vertical support structure provides a stable platform to hold the door slab at the correct height, allowing one person to manage the installation without straining to lift and balance the heavy door manually
4Reliability
If typical supports are used to hold the replacement door, then the door can be supported, but the supports are cumbersome and require many adjustments
Solution Approach 1:
The support system incorporates dynamic adjustability through the adjustable arms with measurement scales and locking mechanisms. The arms can be extended or retracted to match the measured door gap, and the height of the support can be adjusted along the vertical structure. This dynamic capability allows the same support device to accommodate different door sizes and gap requirements without requiring multiple different support tools

AI summary
An adjustable door support for acquiring a door gap and supporting a door slab at a height off a floor equal to the door gap. The adjustable door support comprises a bendable sheet including two outer and two inner sections, and two tie devices. The two inner sections are disposed at an oblique angle relative to one another and form a support slot for receiving a portion of the door slab therein. The support slot has door support edges for engaging the door slab. Each of the tie devices includes a cable tie threaded through the inner sections of the bendable sheet and a locking washer attached to the cable tie by sliding over the cable ties in one direction only. The locking washers are lockable on the cable ties to adjust a distance between the support edges of the adjustable door support and the floor.
