Solution Overview

Problem

Existing firearm accessories fail to provide users with the ability to accurately locate and pinpoint targets from a safe position without exposing themselves as a target, particularly in combat scenarios where they must take cover behind obstacles, and are limited in range of use, compatibility with different firearm types, and obstruct the target image.

Innovation Solution

A rotationally deployable firearm accessory with a mirror base and axle system that allows 360-degree rotational adjustability, enabling target acquisition from any position relative to the firearm, and can be mounted in front of or behind a target viewing device without obstructing the image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mirror accessory is mounted on a firearm to enable target acquisition from safe positions, then the user can locate and fire on targets without exposing themselves, but the accessory obstructs the target image and limits range of use

Engineering Contradiction:
Improveuser safety and target acquisition capabilityVSAvoidimage obstruction and limited range of use
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The mirror accessory incorporates a rotational mechanism that allows it to pivot between a deployed position (where it reflects targets to the user) and a retracted position (where it does not obstruct the target viewing device). This dynamic positioning enables the accessory to provide safety and target acquisition capability when needed while eliminating image obstruction when not in use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The accessory is designed as a separate, modular component that can be independently deployed and retracted, allowing the user to control when the mirror is active and when it is out of the way. This segmentation enables the system to switch between providing protective reflection and maintaining clear sightlines.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the mirror accessory is made rotatable for 360-degree adjustment, then the user can acquire targets from any position, but the device complexity increases

Engineering Contradiction:
Improverange of motion and target acquisition positionsVSAvoidrotational mechanism and mounting system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotational mechanism serves multiple functions: it enables 360-degree adjustment for target acquisition from any position, allows the mirror to be positioned for optimal reflection angles, and provides a means to lock the mirror in specific deployed positions. This multi-functionality justifies the added complexity by providing versatile target acquisition capability.

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

Solution Approach 2:

The rotational mechanism provides dynamic adjustability, allowing the mirror to be quickly repositioned to accommodate different target locations and user positions. This dynamic capability enhances adaptability while the mechanism is designed to be compact and integrated with the firearm mounting system.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the accessory is mounted in front of the target viewing device, then it can reflect targets to the user, but it obstructs the image provided by the viewing device

Engineering Contradiction:
Improvetarget location and reflection capabilityVSAvoidtarget image clarity and viewing device functionality
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The mirror accessory is mounted on a rotational mechanism that allows it to pivot between a deployed position (in front of the viewing device to reflect targets) and a retracted position (behind or aside the viewing device). This dynamic positioning enables the accessory to provide target reflection capability when needed while eliminating image obstruction when not in use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The accessory is designed as a separate, movable component rather than a fixed part of the viewing device, allowing independent control of its position. This segmentation enables the system to switch between providing reflective target information and maintaining clear direct viewing through the device.

Inventive Principle:
Principle #1Segmentation

AI summary

A firearm accessory is rotatable on two axes via a sleeve mounted on a bearing comprising a first and a second part, the second part being rotatable and coupled to the first part and facilitating a central opening and a first rotational motion and protrusions with at least one hinge from the sleeve attaching to a mirror device acting as a second rotational motion. An alternative teaches digital control of a swinging mirror assembly having spring acting ball actuators providing the digital action between the actuators and a surface. In another alternative, two armatures also are taught that connect a reflective device to a bearing mounted sleeve in front of or behind a target viewing device. These may be directly rail mounted with appropriate attachment devices or directly connected to or manufactured as an integral part of a reflex sight, night vision, scope or similar viewing system of a firearm.
