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. 11,857,116.

Summary of the Inventive Concept

The inventive concept expands the detachable handle technology to various industries, including transportation, healthcare, construction, and music, enabling efficient and secure handling of diverse loads, devices, and instruments.

Background and Problem Solved

The original detachable handle patent focused on cooking vessels, but its core technology has broader applicability. The new inventive concept addresses the limitations of the original patent by adapting the detachable handle to tackle distinct challenges in different fields, such as securing loads on trailers, transporting bicycles, supporting medical devices, stabilizing ladders, and carrying musical instrument cases.

Detailed Description of the Inventive Concept

The inventive concept involves modifying the detachable handle's body, lever, pressing member, and spring to accommodate various attachment points and loads. For instance, the system for securing a load on a trailer features a detachable handle adapted for coupling to a trailer hitch, while the detachable handle for a medical device incorporates a device support portion at the front end of the body. The lever and pressing member enable secure attachment and detachment, ensuring efficient handling and minimizing damage.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for the detachable handle technology, demonstrating an inventive step beyond the original patent. The adaptation of the core technology to diverse industries and problems solves specific challenges and provides innovative solutions.

Alternative Embodiments and Variations

Alternative embodiments may include adjustable handles for accommodating different load sizes, ergonomic designs for enhanced user comfort, or materials tailored to specific industries (e.g., medical-grade materials for healthcare applications). Variations could also involve integrating sensors or IoT technology to monitor load stability or provide real-time feedback.

Potential Commercial Applications and Market

The versatile detachable handle technology has significant commercial potential across multiple industries, including transportation, healthcare, construction, and music. Target markets may include trailer manufacturers, medical device suppliers, ladder producers, and musical instrument case manufacturers, among others.

Field of Art

Mechanical engineering focused on detachable handles and coupling mechanisms for various load-bearing applications, with expertise in mechanical design, material selection, and ergonomic attachment systems

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer with 3-5 years of experience in industrial design, familiar with modular attachment mechanisms, capable of adapting standard mechanical coupling principles across different technical domains

Obviousness Rationale

A PHOSITA would recognize the fundamental detachable handle mechanism from US 11857116 as a versatile technical solution that could be readily adapted to multiple load-bearing contexts. The core mechanical principles of the lever, pressing member, and spring-based attachment system are universally applicable across different industries. The PTD demonstrates predictable variations that extend the original patent's core mechanical concept through straightforward design translation.
