Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional particulate material filled buttstock supports are used, then the rifle buttstock can be supported at a raised elevation, but the elevation adjustment requires awkward and time-consuming manipulations of the particulate material
Solution Approach 1:
The patent replaces the conventional particulate material adjustment mechanism with a pneumatic system consisting of an expandable airbag and air pump. By inflating the airbag, the buttstock elevation is adjusted upward; by deflating it, the elevation is lowered. This pneumatic mechanism eliminates the need for manual manipulation of particulate material, providing smooth, precise, and rapid elevation adjustments with minimal effort.
Solution Approach 2:
The invention changes the physical state and volume of the airbag to control buttstock elevation. The airbag can be inflated to increase volume and lift the buttstock, or deflated to decrease volume and lower the buttstock. This parameter-based control (volume/pressure) replaces the discrete manipulation of particulate material, enabling continuous and precise elevation adjustment.
2Measurement precision
If conventional particulate material filled buttstock supports are used, then the rifle buttstock can be supported, but the elevation adjustment is imprecise
Solution Approach 1:
The pneumatic airbag system provides continuous, smooth elevation adjustment without the discrete, jerky movements associated with manipulating particulate material. The air pump can be controlled to inflate or deflate the airbag in small increments, enabling precise elevation control. This pneumatic mechanism allows for fine-tuning of the aiming point with greater precision and ease of operation.
3Productivity
If an expansible airbag and air pump are incorporated into the buttstock support, then precise and efficient elevation adjustments are achieved, but the device complexity increases
Solution Approach 1:
The airbag serves multiple functions: it provides the elevating force, acts as a cushioning element, and functions as the adjustment mechanism itself. The air pump serves dual purposes of inflating and deflating the airbag. This multi-functionality reduces the need for separate components and mechanisms, thereby limiting the increase in overall device complexity while achieving high productivity in elevation adjustments.
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
Enables stable and precise elevation adjustments of a rifle's aiming point with minimal effort, enhancing accuracy and efficiency in long-range shooting.
Implementation Method 1
actuate the invention's air injecting means to cause the expansible airbag to begin to fill with air. Such airbag filling causes an upper surface of the airbag to bias and deflect upwardly against the overlying body of particulate material. Upward pressure exerted by the airbag, in turn causes such material to deflect upwardly, upwardly raising the rifle's rear stock.

AI summary
A buttstock support including a base plate having first and second ends; a first flexible sheet having first and second ends respectively fixedly attached to the base plate's first and second ends; a body of particulate material overlying the base plate and underlying the first flexible sheet; an air bag overlying the base plate and underlying the body of particulate material; and an air pump for injecting air into the air bag. The buttstock support includes a second flexible sheet overlying the airbag and underlying the body of particulate material. The buttstock support also includes a first pocket upwardly and downwardly bounded by the first and second flexible sheets. The buttstock support includes a second pocket, upwardly and downwardly bounded by the second flexible sheet and the base plate. The first pocket is opened by a particulate material port and the second pocket is opened by an air bag port.
