Adjustable Door Frame Assembly for Drill-Free Vertical Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door assemblies require drilling and multiple people to mount, which is time-consuming and can damage surfaces, especially when wall surfaces are not perfectly vertical, making it difficult to maintain the door in a vertical position.
Innovation Solution
A door assembly with an adjusting assembly comprising a detachable rod portion, a cam member, and a fixing element with a cushion, allowing for adjustable distance between stationary and movable frames without drilling, enabling single-person assembly and minimizing surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drilling is used to mount the door assembly, then the stationary and movable frames can be securely connected, but the operation requires at least two people and is time-consuming
Solution Approach 1:
The patent introduces an adjusting assembly as an intermediary component between the stationary frame and movable frame. This assembly includes an adjusting element with a rod portion, a fixing element with cavities, and a cam member that can rotate between open and close positions. The cam member acts as a mediator to secure the rod portion to the fixing element without drilling, enabling single-person installation while maintaining secure connection.
2Strength
If drilling is used to mount the door assembly, then the frames can be securely connected, but the drilling may inadvertently cause damages to the surfaces of the frames
Solution Approach 1:
The adjusting assembly serves as a non-invasive intermediary connection mechanism. The rod portion fits into the first cavity of the fixing element, and the cam member secures it through rotational movement without requiring holes or fasteners that could damage the aluminum frame surfaces. This maintains connection strength while avoiding surface damage.
3Adaptability or versatility
If the door is mounted completely along the wall surface, then the door follows the wall contour, but the door may not be smoothly opened or closed when the wall is not vertical
Solution Approach 1:
The adjusting assembly introduces dynamic adjustability to the door mounting system. The rod portion can be extended or retracted within the first cavity, and the cam member can be rotated between open and close positions. This dynamic mechanism allows the door to be adjusted to maintain vertical position even when mounted on non-vertical walls, ensuring smooth operation while adapting to various wall surfaces.
4Ease of operation
If the distance between the top/bottom end of door and wall surface is adjusted to keep door vertical, then the door can operate smoothly, but the mounting process becomes more complex
Solution Approach 1:
The adjusting assembly provides dynamic adjustment capability through the rod portion and cam member mechanism. The rod can be extended or retracted to adjust the distance between the door and wall surface, while the cam member's rotational movement between open and close positions secures the adjustment. This dynamic system enables smooth door operation on non-vertical walls without requiring overly complex mounting procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for secure mounting of door assemblies without drilling, reducing installation time and risk of surface damage, while enabling vertical alignment of doors on angled walls, facilitating smooth opening and closing.
Implementation Method 1
a cam member receivable in the second cavity, the cam member being rotably connected to the fixing element and movable between an open position and a close position. When the cam member is in the close position, it applies a force to one sidewall of the rod portion such that the other sidewall of the rod portion will apply a force to the fixing element.
Implementation Method 2
the fixing element further comprises a cushion received within the first cavity for contacting with the rod portion to increase the friction force there between. The cushion is made of rubber or plastic materials.

AI summary
A door assembly is disclosed which comprises a stationary frame, a movable frame, and an adjusting assembly. The adjusting assembly comprise an adjusting element detachably connected with the stationary frame and having a rod portion; a fixing element detachably connected with the movable frame and having a first cavity at its top for receiving the rod portion and a second cavity at one side; and a cam member receivable in the second cavity, the cam member being rotably connected to the fixing element and movable between an open position and a close position. The door assembly can be assembled without drilling operation, minimizing risk of damage to the frames, and can be assembled by a single person.
