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. 11,857,064.

Background and Problem Solved

The original tool attachment system, designed for attaching tools to a belt or job site location, had limitations in its adaptability to other industries. The present invention addresses this limitation by applying the core technology to new fields, such as medical devices, furniture assembly, bicycle accessories, sporting goods equipment, and musical instruments, providing a modular solution for diverse attachment needs.

Novelty and Inventive Step

The new claims introduce a novel application of the core technology to diverse industries, providing a non-obvious solution for attachment needs in these fields. The inventive step lies in the recognition of the core technology's potential for broader applicability and the development of a modular system that can be adapted to various industries.

Alternative Embodiments and Variations

Alternative embodiments may include different receiver designs, attachment devices, or locking mechanisms tailored to specific industries. Variations may also include additional features, such as sensors or actuators, to enhance the attachment system's functionality.

Potential Commercial Applications and Market

The modular attachment system has significant commercial potential in various industries, including healthcare, furniture, sports, and music. The system's adaptability and convenience can increase efficiency, reduce costs, and enhance user experience, making it an attractive solution for companies and individuals seeking innovative attachment solutions.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Mechanical attachment systems and modular coupling technologies, with expertise in removable mounting mechanisms for tools, equipment, and accessories across various industries

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer with 3-5 years of experience in design of attachment systems, familiar with pivot mechanisms, locking interfaces, and adaptable mounting solutions across multiple technical domains

Obviousness Rationale

The source patent discloses a fundamental attachment system with a receiver, locking mechanism, and rotatable coupling that can be readily adapted to different contexts. A PHOSITA would recognize the core technical principles as universally applicable across industries by simply substituting the specific attachment point and target device while maintaining the core mechanical functionality of the original invention.

Obvious Combinations & Variations

Source Patent Element

Receiver with channel and locking hole configured to attach to a belt

PTD Variation

Receiver configured to attach to medical gown, furniture frame, bicycle frame, equipment holder, or musical instrument

Obviousness Reasoning

Substituting attachment surfaces is a predictable design variation that would be obvious to a PHOSITA as a simple matter of mechanical adaptation

Source Patent Element

Tool attachment device with pivotal coupling mechanism

PTD Variation

Medical device, furniture component, bicycle accessory, sporting equipment, or musical instrument attachment device using identical pivotal coupling principle

Obviousness Reasoning

The rotational coupling mechanism is a known technique that can be universally applied across different technical domains with minimal modification

Source Patent Element

Locking mechanism allowing selective attachment and removal

PTD Variation

Locking mechanism adapted for medical, furniture, bicycle, sporting, and musical instrument contexts

Obviousness Reasoning

Fundamental locking interface principles remain consistent across domains, representing a finite set of predictable mechanical solutions

Source Patent Element

Single fluid motion attachment and removal system

PTD Variation

Applying single fluid motion principle to diverse attachment scenarios in different industries

Obviousness Reasoning

Ergonomic design principles are transferable across technical domains as a matter of standard engineering practice

35 U.S.C. § 103 Summary: Based on US Patent 11857064, the disclosed variations represent obvious extensions of the core attachment system technology through predictable mechanical adaptations that would be readily conceived by a person having ordinary skill in mechanical design, thereby rendering potential claims to these variations unpatentable under 35 U.S.C. § 103 as obvious variants of the prior art.
