Vertically Adjustable Strike Plate With Fixed Jamb Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aligning the door bolt and strike plate opening vertically is challenging during installation and can become misaligned over time due to structural shifts, requiring time-consuming adjustments by removing and repositioning the strike plate screws, which is difficult with security screws and old wood.
Innovation Solution
A vertically adjustable strike plate assembly that allows for precise vertical alignment adjustments without loosening or removing attachment screws, using interlocking teeth and valleys on the strike plate and baseplate to secure the bolt position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the strike plate is adjusted vertically by removing and repositioning attachment screws, then vertical alignment of the bolt and strike plate opening can be corrected, but the adjustment process becomes time-consuming and difficult especially with security screws and old wood
Solution Approach 1:
The strike plate assembly incorporates a vertical adjustment mechanism that allows the strike plate to be repositioned vertically relative to the base plate while the assembly remains attached to the door jamb. This dynamic adjustment capability enables alignment correction without removing attachment screws, resolving the contradiction between achieving precise vertical alignment and minimizing adjustment time.
Solution Approach 2:
The strike plate assembly is divided into separate components (strike plate and base plate) that can be adjusted independently. The strike plate can be vertically repositioned on the base plate through adjustment holes and positioning screws, allowing precise alignment adjustment without disturbing the attachment screws that secure the assembly to the door jamb.
2Manufacturing precision
If the strike plate is adjusted vertically by removing attachment screws, then alignment can be corrected, but the attachment screws may be damaged or difficult to reinstall in exact original positions
Solution Approach 1:
The adjustment mechanism separates the alignment adjustment function from the attachment function. The strike plate can be vertically adjusted on the base plate using adjustment holes and positioning screws, while the attachment screws remain fixed in their original positions securing the assembly to the door jamb. This eliminates the risk of damaging attachment screws during adjustment.
Solution Approach 2:
The base plate serves as an intermediary component between the attachment screws and the strike plate. The strike plate adjusts vertically on the base plate through adjustment holes, while the attachment screws attach the base plate to the door jamb. This intermediary structure allows alignment adjustment without directly manipulating the attachment screws.
3Device complexity
If traditional strike plate installation is used without adjustment mechanism, then the structure remains simple, but vertical alignment becomes challenging and time-consuming during installation
Solution Approach 1:
The strike plate assembly incorporates a vertical adjustment mechanism that allows the strike plate to be repositioned vertically relative to the base plate while the assembly remains attached to the door jamb. This dynamic adjustment capability enables alignment correction without removing attachment screws, resolving the contradiction between achieving precise vertical alignment and minimizing adjustment time.
Solution Approach 2:
The base plate is pre-installed on the door jamb with attachment screws, providing a stable foundation. The strike plate is then added with adjustment holes that allow vertical positioning during installation. This preliminary action simplifies the overall installation process by establishing a stable base before performing the alignment adjustment.
