Solution Overview

Problem

Conventional firearm mounts are not adjustable to accommodate different user heights and arm lengths, leading to instability and discomfort during use, and often require specialized tools or result in alignment issues with accessories.

Innovation Solution

A quick-release mounting system with a frame and base configuration that is spring-biased and adjustable via a lever mechanism, allowing for secure attachment to firearm rails without damaging the rifle or rail, and accommodating varying rail sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional firearm mounts are used, then accessories can be mounted on the weapon, but the mounts are not adjustable to accommodate different user heights and arm lengths, leading to instability and discomfort

Engineering Contradiction:
Improveadjustability to different user heights and arm lengthsVSAvoidstability of the mount
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mount incorporates an adjustable mechanism that allows the mounting position to be dynamically changed along the rail to accommodate different user anthropometry. The adjustable component can be positioned at multiple discrete locations along the rail length, enabling customization while maintaining stable attachment at each position through the locking mechanism.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional mounting systems are used, then accessories can be attached to the firearm, but specialized tools are required for installation and adjustment

Engineering Contradiction:
Improveease of installation and adjustmentVSAvoidcomplexity of the mounting system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting system employs a toolless adjustment mechanism where the user can directly manipulate the mounting component along the rail using hand operations. The design includes user-friendly features such as movable components that can be slidingly adjusted and locked into position without requiring external tools, making the system self-servicing for the end user.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If conventional rails are mounted on the handguard, then accessories can be mounted, but the alignment of the accessory relative to the barrel changes slightly during firing or if the weapon receives a shock

Engineering Contradiction:
Improvealignment precision of accessory relative to barrelVSAvoidconsistency of alignment under shock and firing conditions
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The mounting system is divided into separate functional components: a floating rail portion that can move independently to absorb shocks and maintain alignment, and a fixed attachment portion to the handguard. This segmentation allows the rail to decouple from direct shock transmission while maintaining precise accessory alignment through the floating mechanism.

Inventive Principle:
Principle #1Segmentation

4Stability of the object's composition

If floating rails attached only at the rear are used, then stability over time is improved, but alignment problems occur due to shock from firing gases and armorer assembly is required

Engineering Contradiction:
Improvestability over timeVSAvoidalignment precision
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The mounting system combines multiple functions in a single integrated design: it provides stable long-term attachment through the floating rail mechanism, maintains alignment precision through shock-absorbing features, and enables user-friendly toolless installation and adjustment. The universal design accommodates various accessory types while maintaining consistent alignment and stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
