Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld weapons face accuracy issues due to recoil, which alters target alignment, especially in environments lacking stable support, and existing gyroscopes are too bulky and heavy for practical use.
Innovation Solution
A motorized weapon gyroscopic stabilizer system with a lightweight, high-speed brushless motor-driven gyroscope integrated into the weapon's structure, providing stability by altering the mass, speed, and diameter of the spinning element, and designed to be quiet and compact, allowing for attachment to the weapon's barrel or other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional gyroscopes are used for weapon stabilization, then gyroscopic stability is improved, but weight and bulk increase significantly
Solution Approach 1:
The patent changes the operational parameters of the gyroscope by increasing the rotational speed to extremely high RPMs (e.g., 50,000-100,000 RPM or higher). This parameter change allows the use of a much smaller and lighter spinning mass while achieving the same gyroscopic stability effect, as gyroscopic stability is proportional to the product of mass, radius squared, and rotational speed.
Solution Approach 2:
The patent utilizes high-frequency rotational vibration of the gyroscope rotor to achieve stabilization. The extreme rotational speed creates a vibrating spinning mass that provides gyroscopic stability through dynamic motion rather than static mass, enabling a lightweight design that would be impossible with traditional low-speed gyroscopes.
2Power
If traditional DC motors with brushes are used to drive the gyroscope, then motor power is achieved, but noise and mechanical complexity increase
Solution Approach 1:
The patent replaces the traditional mechanical brush-and-commutator system with an electronic commutation system using Hall effect sensors or other position sensors to detect rotor position and control the timing of current pulses to the stator windings. This substitution eliminates mechanical contact, removing the source of noise and wear while maintaining full motor power capability.
Solution Approach 2:
The patent introduces electronic intermediaries (microcontroller, power electronics, position sensors) between the power source and the motor to enable brushless operation. These electronic components mediate the energy transfer and control functions previously performed by mechanical brushes, achieving noise-free operation while maintaining precise motor control.
3Stability of the object's composition
If the gyroscope diameter is increased to improve stability, then gyroscopic stability improves, but device bulk and weight increase
Solution Approach 1:
The patent fundamentally changes the operational parameter of rotational speed to compensate for the reduced diameter. By increasing speed by factors of 100 or more compared to traditional gyroscopes, the patent achieves equivalent gyroscopic stability (which depends on the product of moment of inertia and angular velocity squared) with a dramatically smaller volume.
Solution Approach 2:
The patent transitions from relying on the spatial dimension (large diameter) to achieving stability through the temporal dimension (extremely high rotational speed). This dimensional shift allows the same stabilization effect to be achieved in a compact form factor by operating in the time domain rather than the space domain.

Function Achieved in This Case
The motorized weapon gyroscopic stabilizer enhances stability during single, semi-automatic, and fully automatic shots by minimizing recoil impact on target alignment, enabling faster reacquisition and improved accuracy without adding bulk or noise.
Implementation Method 1
A motorized weapon stabilizer system utilizes a relatively small diameter, low mass, high speed brushless motor driven gyroscope created with integral construction to the weapon, designed to spin on an axis parallel to the weapons direction of fire
Implementation Method 2
an electronic motor includes a rotor configured to provide gyroscopic stability, the rotor surrounding the open core and including an axis of rotation and a mass element configured to rotate around the axis of rotation

AI summary
A motorized weapon gyroscopic stabilizer which creates a stabilizing effect for single shot, semi-automatic, and fully automatic weapons. The rotating mass that generates the gyroscopic stabilizing effect is the rotor of the motor. The motor is designed to allow the mass to rotate around the open core of the motorized weapon gyroscopic stabilizer. Because of its open core design the motorized weapon gyroscopic stabilizer allows the fired projectile to pass through it, or be mounted in line with the sighting mechanism allowing the target alignment—line of sight to pass through the motorized weapon gyroscopic stabilizer, or both.
