Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Picatinny rail brackets with multiple sets of dovetail grooves for different widths result in increased thickness and material consumption.
Innovation Solution
A width-adjustable Picatinny rail bracket with a fixed and movable arm, featuring lifting grooves and elastic reset members to adjust clamping widths, allowing the lifting arms to sink into the grooves when not in use, thereby reducing the overall thickness and material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sets of dovetail grooves with different widths are provided in the height direction to clamp the Picatinny rail and the quick-mount plate, then the bracket can accommodate different models and accessories, but the thickness and material consumption of the bracket increase
Solution Approach 1:
The lifting arm is designed to be movable between a lifted-up state (forming a first clamping groove with smaller width) and a storage state (forming a second clamping groove with larger width). This dynamic reconfiguration allows the bracket to adapt between different clamping width requirements without providing both grooves simultaneously, thereby reducing the bracket's thickness and material consumption while maintaining versatility
Solution Approach 2:
The lifting arm serves multiple functions: when lifted up, it forms a narrow clamping groove for Picatinny rails; when in storage state, it allows formation of a wide clamping groove for quick-mount plates. This multi-functionality enables a single component to replace what would traditionally require multiple fixed structures, reducing overall bracket thickness
2Adaptability or versatility
If multiple sets of dovetail grooves with different widths are provided in the height direction, then the bracket can clamp different widths, but the material consumption of the bracket increases
Solution Approach 1:
The lifting arm transitions between lifted-up and storage states to dynamically create different clamping groove widths. This eliminates the need to manufacture multiple permanent grooves of different widths, thereby reducing material consumption while maintaining the capability to clamp different widths
Solution Approach 2:
The bracket is segmented into fixed components (fixed bracket with fixed arm) and movable components (lifting arm that can be positioned in different states). This segmentation allows the movable lifting arm to create different clamping configurations without requiring the entire bracket structure to accommodate all possible widths simultaneously, reducing overall material usage
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 enables adjustable clamping widths without the need for a step groove channel, resulting in a thinner bracket design that uses less material and reduces costs.
Implementation Method 1
first elastic reset members that are connected to the lifting arm and used for driving the lifting arm to be lifted up are provided in the lifting groove
Implementation Method 2
a second elastic reset member that abuts against the lock rod is provided in the communication hole, an end cover that abuts against an outer end of the second elastic reset member is provided at an outer end of the communication hole, and the second elastic reset member provides an elastic force for the lock rod to move in a direction towards the fixed groove

AI summary
The present invention discloses a width-adjustable Picatinny rail bracket, which comprises a fixed bracket and a movable bracket, and a movable arm is provided on the movable bracket. By providing at least one lifting groove on a top of the fixed bracket and installing a lifting arm in the lifting groove, a clamping groove with the largest clamping width is formed by a fixed arm and the movable arm to clamp a quick-mount plate with the largest size; and when a Picatinny rail needs to be clamped, the corresponding lifting arm is controlled to be lifted up to a lifted-up state, so that the lifting arm is cooperated with the movable arm to form a clamping groove with a suitable width to clamp the Picatinny rail. The bracket has a lower entire thickness and saves materials at the same time.
