Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional firearm sights fail to accurately indicate when the firearm is not kept horizontal, affecting shooting accuracy due to the lack of a mechanism to detect and correct for non-standard attitudes.

Innovation Solution

A bi-reticle sight system featuring a first reticle that moves with the firearm's main body and a second reticle that adjusts relative to the first when the firearm is not in a standard attitude, utilizing an angular position sensor to detect deviations and adjust the second reticle's position accordingly, ensuring the user is aware of the firearm's orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If only one reticle is set in the sight, then the structure is simple, but the user cannot perceive when the firearm is not horizontal

Engineering Contradiction:

Improveuser perception of firearm attitudeVSAvoidreticle system structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The single reticle is segmented into two distinct reticles: a first reticle that moves with the main body and a second reticle that remains fixed or moves differently. This segmentation allows the user to perceive attitude deviations through the relative position of the two reticles, while keeping each individual reticle structure relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an attitude detection mechanism as an intermediary between the firearm's physical state and the reticle display. This mediator detects the firearm's attitude and controls the second reticle's position, enabling indirect visualization of attitude deviations without requiring direct mechanical coupling between the reticle and firearm orientation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the reticle moves along with the firearm, then the reticle remains aligned with the firearm's movement, but the user fails to perceive non-horizontal positions

Engineering Contradiction:

Improvereticle alignment with firearmVSAvoidfirearm attitude information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent implements dynamic behavior where the first reticle moves with the main body while the second reticle's position is dynamically adjusted based on detected attitude deviations. This dynamic configuration allows the reticle system to adapt to firearm movement while simultaneously providing attitude information, resolving the contradiction between maintaining alignment and preserving information.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The attitude detection mechanism provides feedback about the firearm's orientation to the reticle system. The second reticle's position is adjusted based on this feedback, creating a closed-loop system that maintains reliable alignment while preventing loss of attitude information through the visible deviation between the two reticles.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If a sensor is added to detect the main body attitude, then the firearm orientation can be detected, but the device complexity increases

Engineering Contradiction:

Improvefirearm attitude detectionVSAvoidsensor and control system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical attitude indication mechanisms with electronic sensors and control systems. Instead of using purely mechanical linkages between the firearm body and reticle, electronic sensors detect attitude and electronically control the second reticle's position, achieving precise measurement with potentially simpler overall system architecture.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operational parameters of the reticle system by introducing electronically controlled position adjustment. Rather than maintaining fixed mechanical relationships, the system dynamically changes reticle position parameters based on sensor input, enabling precise attitude detection while allowing flexibility in system design.

Inventive Principle:

Principle #35Parameter changes

AI summary

A bi-reticle sight includes a main body, a first reticle, a second reticle and a sensor. The first reticle is configured to move along with the main body. The second reticle is configured to move relative to the first reticle. The sensor is configured to detect the main body to determine whether the main body is in a standard attitude. Wherein the first reticle coincides with the second reticle when the main body is in the standard attitude, the second reticle is moved relative to the first reticle to a position corresponding to the standard attitude when the main body is not in the standard attitude.
