Solution Overview

Problem

Existing bipod firearm supports fail to adjust to uneven terrain, leading to canting and reduced accuracy when shooting on slopes, requiring manual leg adjustments that can miss shooting opportunities.

Innovation Solution

A bipod design with pivotally movable legs connected via coil springs, allowing independent angular flexure to compensate for uneven terrain, ensuring stable firearm positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the legs of the bipod have fixed lengths, then the structure is simple and stable, but the firearm cannot be adjusted to different heights and will cant on uneven terrain

Engineering Contradiction:
Improveadaptability to uneven terrainVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the bipod legs movable and adjustable rather than fixed. Each leg can be independently extended or retracted along its respective bore segment, allowing the bipod to adapt to uneven terrain while maintaining a relatively simple overall structure. The legs can be positioned at different lengths to compensate for ground irregularities without requiring complex mechanical systems.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the legs of the bipod are manually adjustable, then the height can be changed, but the shooter may miss shooting opportunities due to adjustment time

Engineering Contradiction:
Improveheight adjustabilityVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-positioning the legs within the bore segments at various potential positions. The legs can be quickly deployed to appropriate lengths without requiring complex manual adjustment mechanisms during the shooting moment. The structure allows for rapid configuration by simply extending or retracting the legs along the predetermined paths within the bore segments.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system for a bipod. The system includes a coupler to couple at least one leg to a firearm. The leg includes one flexible joint which allows the leg to flex about a flexible joint. The system allows conversion of the flexible leg from a flexible position to a rigid position whereby flexing about the flexible joint is prevented. A lock is manipulated to convert the leg from rigid to flexible.
