pr1or.art Inc., “Advanced Multi-Industry Folding Umbrella Technology,” Published Technical Disclosure No. 24-11857041_0007_PTD, Published October 27, 2025, available at https://archive.pr1or.art/24-11857041_0007_PTD
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. 11,857,041.

Background and Problem Solved

The original patent disclosed a special-shaped folding umbrella designed for personal use. However, its limitations in terms of adaptability and functionality hindered its application in diverse industries. The present invention addresses these limitations by extending the core technology to cater to the unique requirements of various fields, offering a more comprehensive and effective solution.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for the special-shaped folding umbrella, which were not originally considered. The inventive step lies in the adaptation of the core technology to cater to the unique requirements of diverse industries, resulting in a more comprehensive and effective solution.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include variations in canopy materials, shaft designs, and anchoring systems to further expand its applicability. For instance, the umbrella could be designed with a solar panel canopy for generating electricity or a self-cleaning canopy for use in dusty environments.

Potential Commercial Applications and Market

The special-shaped folding umbrella has immense commercial potential in various industries, including agriculture, construction, emergency response, and outdoor recreation. The target market includes farmers, construction companies, emergency response teams, event organizers, and outdoor enthusiasts, offering a unique solution for their specific needs.

Field of Art

Umbrella design and portable shelter technologies, encompassing mechanical engineering of collapsible structures, fabric integration, and multi-purpose protective equipment

Person of Ordinary Skill (PHOSITA) Profile

An engineer with expertise in mechanical design, materials science, and structural engineering, familiar with umbrella mechanisms, telescoping structures, and adaptable protective equipment

Obviousness Rationale

A PHOSITA would recognize that the source patent's special-shaped folding umbrella provides a fundamental modular design that can be readily adapted to various environmental and functional contexts. The core mechanical principles of retractable shafts, interconnected ribs, and fabric canopies inherently suggest multiple potential applications beyond personal weather protection. The disclosed variations represent predictable extensions of the original umbrella technology by applying known engineering principles to specific use cases.
