Adjustable Strike Plate Assembly for Door Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional strike plates are difficult to adjust and prone to contamination, making it challenging to maintain precise alignment and secure door retention in moving structures like vehicles and aircraft, leading to vibrations and noise.
Innovation Solution
An adjustable strike plate assembly with a cover plate, striker, alignment structure, and fastening mechanism that allows for multiple orientations of the bolt receptacle, enabling precise alignment and secure retention of the bolt, while shielding the alignment structure from contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the clearance between the bolt and the bolt receptacle is decreased to reduce door motion, then door stability is improved, but alignment precision requirements increase and adjustment difficulty increases
Solution Approach 1:
The strike plate incorporates an adjustable mechanism that allows the bolt receptacle position to be dynamically changed after installation. The adjustment mechanism enables the receptacle to be repositioned along the door edge to achieve proper alignment with the bolt, resolving the contradiction between maintaining tight clearance for stability and enabling easy alignment adjustment.
Solution Approach 2:
The invention allows changing the positional parameter of the bolt receptacle relative to the door edge through an adjustment mechanism. This enables the receptacle to be positioned at different locations along the door edge, facilitating alignment with the bolt while maintaining the required tight clearance for door stability.
2Device complexity
If traditional strike plates are used with fixed bolt receptacle position, then device simplicity is maintained, but adjustment capability is limited and contamination susceptibility increases
Solution Approach 1:
The strike plate transforms from a fixed structure to a dynamically adjustable one. The adjustment mechanism allows the bolt receptacle to be repositioned along the door edge, providing adaptability for different alignment requirements while maintaining relative structural simplicity through the use of a straightforward mechanical adjustment system.
3Adaptability or versatility
If the strike plate is mounted on a floor where particulate material collects, then installation flexibility is improved, but contamination risk increases and adjustment mechanism reliability decreases
Solution Approach 1:
The adjustment mechanism is designed to be accessible from the interior side of the door, extracting the adjustment operation away from the contaminated exterior environment. This allows users to adjust the strike plate without exposing the adjustment mechanism to particulate material on the floor, thereby maintaining reliability while preserving installation flexibility.
4Measurement precision
If multiple orientations of the bolt receptacle are enabled, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The strike plate uses a simple rotational adjustment mechanism that allows the bolt receptacle to be oriented at multiple angles relative to the door edge. This dynamic positioning capability provides precise alignment options without requiring a complex multi-component structure, achieving high alignment precision with minimal added complexity.

AI summary
Adjustable strike plate assemblies and systems and methods including the same are disclosed herein. The assemblies include a cover plate that defines a lock-facing side, an opposed striker-facing side, and a striker opening. The assemblies further include a striker that defines a bolt receptacle that is sized to receive a bolt of a lock. The bolt receptacle is aligned within the striker opening to define a bolt-receiving portion of the strike plate assembly. The assemblies further include an alignment structure that aligns the striker with the cover plate to define a plurality of orientations of the bolt receptacle relative to the striker opening. In operation, the striker-facing side of the cover plate generally faces toward the striker and the alignment structure. The assemblies further include a fastening structure that selectively retains the bolt receptacle in a selected orientation of the plurality of orientations.
