Adjustable Door Handle Mounting Post for Misaligned Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of door handlesets is challenging due to misalignment of the mounting post with the lower hole in the door, leading to customer returns and difficulties in drilling the proper location, with existing designs offering limited flexibility in adjusting the mounting post.
Innovation Solution
A door handle design featuring a lower mounting plate with a pivotable arm and a rotating arm that allows the mounting post to move up-and-down and side-to-side within a recessed area, enabling precise alignment with the door hole through a combination of rotational and sliding movements, and a retaining plate for structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting post is used, then the structure is simple and stable, but the mounting post cannot be adjusted to align with the lower hole in the door
Solution Approach 1:
The mounting post is transformed from a fixed component to a movable one through the pivotable arm mechanism. The arm can rotate about a pivot point, allowing the mounting post to dynamically adjust its position to align with the lower hole in the door while maintaining structural stability through the pivot connection.
Solution Approach 2:
The mounting mechanism is divided into separate functional components: the lower mounting plate, the pivotable arm, and the mounting post. This segmentation allows each component to perform its specific function independently - the plate provides mounting surface, the arm provides adjustment capability, and the post provides the actual mounting function.
2Reliability
If the mounting post position is fixed, then the installation process is straightforward, but misalignment with the lower hole leads to customer returns
Solution Approach 1:
The pivotable arm is pre-configured with a pivot point that allows rotational movement. This preliminary design enables the installer to adjust the mounting post position during installation by simply rotating the arm, ensuring alignment with the lower hole without requiring complex procedures or specialized tools.
3Adaptability or versatility
If existing adjustment mechanisms are used, then some flexibility is provided, but the adjustment range is limited and insufficient for proper alignment
Solution Approach 1:
The adjustment mechanism provides freedom of movement in multiple dimensions through the pivotable arm rotation. The arm can rotate about the pivot point to accommodate variations in hole position both vertically and horizontally, effectively adding dimensional flexibility to the mounting system.

AI summary
The present disclosure relates to a door handle having a grip with a first end and a second end. The door handle further includes an upper mounting plate coupled to the first end of the grip and a lower mounting plate coupled to the second end of the grip. A mounting post is coupled to the lower mounting plate and is configured to move relative to the lower mounting plate. Means for adjusting the position of the mounting post with respect to the lower mounting plate facilitate movement of the mounting post along at least two axes. The means for adjusting the mounting post may further comprise a rotating arm that is pivotally connected to the lower mounting plate and to which the mounting post is attached.
