Rifle Stock Offset Device with Parallel Pivot Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle stock adjustment systems are complex, requiring multiple fixing devices and resulting in misalignment and difficulty in setting, especially due to significant forces acting on locking screws, making adjustments cumbersome and inconvenient.
Innovation Solution
A setting device with parallel, pivotably mounted adjusting elements and a fixing device that includes a rotatable clamping piece, preventing unintentional adjustments by utilizing frictional force for secure locking, allowing for intuitive and effective single-fixation pivoting without external help.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fixing devices are used to adjust the rifle stock, then the adjustment can be secured, but the complexity of the device and the number of parts increase
Solution Approach 1:
The patent combines multiple fixing functions into a single fixing device that simultaneously secures both adjusting elements. The fixing device includes a single fastening element that can lock both the first and second adjusting elements in their adjusted positions, eliminating the need for separate fixing devices for each element and reducing overall device complexity while maintaining reliable adjustment securing.
2Reliability
If multiple locking screws are used to fix the adjusting elements, then the adjustment is secured, but the force required for adjustment increases and handling becomes difficult
Solution Approach 1:
The patent merges multiple locking screws into a single fastening element that performs the locking function for both adjusting elements simultaneously. This single fastening element can be operated with one hand, significantly improving ease of operation while still providing secure locking of both adjusting elements in their adjusted positions.
3Reliability
If individual fixing of multiple axles is required, then each axle can be secured, but the adjustment process becomes time-consuming and may result in misalignment
Solution Approach 1:
The patent combines the fixing of multiple axles (first and second adjusting elements) into a single operational step. The fixing device is designed to simultaneously secure both adjusting elements when the fastening element is tightened, eliminating the need for sequential individual fixing and reducing the adjustment process time while preventing misalignment through simultaneous positioning.
4Adaptability or versatility
If complicated attachments are used for adjustment, then more adjustment options are available, but the device becomes expensive and complex
Solution Approach 1:
The patent designs the fixing device with multi-functionality, where a single fixing device structure can accommodate and secure multiple types of adjusting elements. The fixing device includes a fastening element and retaining structure that can work with both the first and second adjusting elements, providing versatile adjustment options without requiring separate complicated attachments for each adjustment type.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, intuitive, and misalignment-free adjustments of the rifle stock, reducing the complexity and force required for setting, allowing shooters to make adjustments independently and efficiently.
Implementation Method 1
a relative movement of the adjusting elements to one another is prevented by the frictional force that occurs
