This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,852.

Summary of the Inventive Concept

A system for adjusting the center of gravity of various devices, including robotic arms, wearable devices, drones, and self-balancing vehicles, to improve their performance, stability, and agility.

Background and Problem Solved

The original patent, 'Golf club head with vertical center of gravity adjustment,' demonstrated the importance of center of gravity positioning in golf club heads. However, this technology has broader applications beyond the golf industry. The inventive concept addresses the limitations of fixed center of gravity designs in various devices, leading to suboptimal performance, instability, and reduced agility.

Detailed Description of the Inventive Concept

The movable weight assembly is a modular component that can be attached to a device, allowing for real-time adjustments to its center of gravity. This assembly consists of a weight carrier and a weight, which can be moved along a predetermined path to alter the device's center of gravity. In a robotic arm, the movable weight assembly enables precise trajectory control. In a wearable device, it enhances athletic performance by adjusting the user's center of gravity for improved balance and agility. In a drone, it ensures stable flight, and in a self-balancing vehicle, it maintains optimal balance.

Novelty and Inventive Step

The inventive concept introduces a new application of the movable weight technology, extending its use beyond golf club heads to various devices that require center of gravity adjustments. The novelty lies in the adaptation of this technology to address specific challenges in diverse industries, providing a non-obvious solution to the problem of fixed center of gravity designs.

Alternative Embodiments and Variations

Alternative embodiments may include using different types of weights, such as liquid or gas-filled containers, or incorporating sensors and AI algorithms to optimize center of gravity adjustments. Variations may also include integrating the movable weight assembly with other components, such as actuators or gyroscopes, to enhance device performance.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in industries such as robotics, wearable technology, drone manufacturing, and self-balancing vehicle production. The technology can be licensed to companies in these industries, enabling them to develop more efficient, stable, and agile devices that improve user experience and performance.
