Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boresight devices are cumbersome, inaccurate, difficult to align, and have limited battery life, making the firearm zeroing process time-consuming and wasteful of ammunition.
Innovation Solution
A boresight device designed to be loaded into the chamber of a firearm in place of the bolt carrier group, featuring keyed features for self-alignment with the barrel and a user-swappable laser device for efficient alignment of the sighting device with the barrel axis, along with a power actuator and removable cap for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional boresight devices are used, then alignment can be achieved, but the devices are cumbersome and difficult to align
Solution Approach 1:
The boresight device is segmented into modular components including a casing that interfaces with the firearm chamber, a separately insertable laser device, and keyed alignment features. This segmentation allows each component to be optimized independently and simplifies the overall alignment process.
Solution Approach 2:
The device incorporates keyed features and alignment mechanisms that enable automatic self-alignment when the casing is loaded into the firearm chamber. The keyed features engage with corresponding features in the chamber to automatically orient the exit port with the barrel axis, eliminating the need for manual alignment adjustments.
2Measurement precision
If multiple zeroing iterations are performed, then accurate sighting can be achieved, but time and ammunition are wasted
Solution Approach 1:
The boresight device provides preliminary alignment of the sighting device to the barrel axis before actual firing occurs. By projecting a laser beam that precisely indicates the barrel's axis, the system establishes an initial accurate reference point, eliminating the need for multiple iterative adjustments and reducing both time and ammunition consumption.
3Ease of operation
If a fixed laser device is used, then alignment is provided, but battery life is limited
Solution Approach 1:
The laser device is designed to be user-swappable rather than fixed, allowing the user to replace depleted laser modules with fresh ones. This dynamic configuration maintains operational convenience while effectively extending the total duration of action through multiple laser device cycles.

AI summary
A boresight device includes a casing designed to be loaded into a chamber of a firearm in the place of a bolt carrier group. The casing may include one or more keyed features to engage with corresponding components of the firearm such that the one or more keyed features align an exit port in the casing to a barrel of the firearm upon loading of the casing into the chamber. The boresight device may further include a laser device for generating a laser beam. The laser device is positioned within the casing to direct the laser beam through the exit port of the casing and along an axis of the barrel when the casing is loaded into the chamber.
