Solution Overview

Problem

Existing laser aiming apparatuses for firearms lack a compact and convenient mechanism for making fine and accurate elevation and windage adjustments, which are essential for ensuring that the laser beam's impact point accurately represents the bullet's trajectory.

Innovation Solution

A laser aiming apparatus with a pivotally mounted sleeve and rocker mechanism, where the rocker is biased and adjustable, allowing for precise adjustments of the laser beam's path by translating set screws that interact with springs and spherical surfaces to pivot the sleeve about fixed points, enabling incremental elevation and windage adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional adjustment mechanism is used for elevation and windage compensation, then the laser aiming apparatus can be adjusted, but the mechanism becomes bulky and difficult to manipulate for fine adjustments

Engineering Contradiction:
Improveadjustment precisionVSAvoidmechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The adjustment mechanism is segmented into two independent rotational degrees of freedom: azimuth adjustment (horizontal) and elevation adjustment (vertical). Each degree of freedom has its own set of adjustment screws and spring mechanisms, allowing independent fine-tuning without interfering with the other axis. This segmentation enables precise adjustments while keeping each subsystem compact and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustment mechanism employs spherical surfaces and ball-and-socket joint geometries to enable smooth rotational adjustments in multiple directions. The spherical contact surfaces allow the laser module to pivot freely around the azimuth and elevation axes, providing intuitive and precise control with minimal friction. This curved geometry replaces complex multi-link mechanisms with simple spherical articulations.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Volume of moving object

If the laser aiming apparatus is made compact, then it is more convenient to mount and carry, but the adjustment mechanism becomes harder to manipulate for fine and accurate adjustments

Engineering Contradiction:
Improveapparatus volumeVSAvoidadjustment ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The adjustment mechanism uses spring-loaded components that provide dynamic, responsive feedback during adjustment. The springs maintain constant contact pressure between adjustment surfaces, ensuring smooth and controllable movement throughout the adjustment range. This dynamic mechanism allows fine adjustments with minimal force while maintaining compact dimensions, as the spring force compensates for the reduced mechanical leverage in a compact design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Spherical intermediary elements (balls or spherical surfaces) are used as mediators between the adjustment screws and the laser module mounting structure. These spherical intermediaries convert linear screw motion into smooth rotational movement, providing mechanical advantage in a compact package. The spherical contact points reduce friction and allow precise control with minimal adjustment force, solving the conflict between compact size and adjustment ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the pivot points are spaced further apart, then the adjustment leverage is improved, but the overall device size increases

Engineering Contradiction:
Improveadjustment leverageVSAvoiddevice length
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The use of spherical contact surfaces and ball joints creates effective mechanical leverage without requiring long adjustment arms. The spherical geometry concentrates forces at the contact point, maximizing the moment arm effect within a compact volume. This allows adequate adjustment leverage to be achieved with minimal spacing between pivot points, keeping the device length short while maintaining ease of operation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The mechanism replaces traditional long-lever mechanical adjustment systems with a compact spherical pivot system. Instead of using long threaded rods or complex linkages to achieve sufficient leverage, the invention uses spherical articulations with spring-loaded adjustment screws that provide adequate mechanical advantage in a shortened configuration. This substitution reduces the device length while preserving adjustment effectiveness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
