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. 11,857,072.

Background and Problem Solved

The original patent disclosed a drawer rear wall for a drawer, comprising a first fastening portion for fixing the drawer rear wall to a first sidewall of the drawer, and a second fastening portion for fixing the drawer rear wall to a second sidewall of the drawer. However, the original patent did not consider the application of this core technology to other industries, such as shipping containers and transportation vehicles. The present invention addresses the problem of securing cargo in these environments, where the original patent's limitations are overcome by adapting the drawer rear wall for use in shipping containers and transportation vehicles.

Novelty and Inventive Step

The new claims introduce the novel concept of applying the core technology of the original patent to the entirely new field of shipping containers and transportation vehicles. The inventive step lies in the adaptation of the drawer rear wall for use in these environments, and the configuration of the cargo restraint system to interact with the drawer rear wall to secure cargo.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include variations in the design of the drawer rear wall, such as different materials or geometries, or alternative configurations of the cargo restraint system. Additionally, the invention could be implemented in other types of containers or vehicles, such as railcars or air cargo containers.

Potential Commercial Applications and Market

The invention has significant commercial potential in the shipping and logistics industry, where cargo security is a critical concern. The modular design and adaptability of the system make it an attractive solution for a wide range of transportation vehicles and containers. The market for cargo securing systems is substantial, and the present invention offers a unique and innovative solution to a long-standing problem.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Mechanical engineering, specifically container and drawer design, focusing on structural components for cargo management and transportation equipment

Person of Ordinary Skill (PHOSITA) Profile

An engineer with expertise in mechanical design, material selection, and transportation equipment manufacturing, capable of adapting structural components across different industrial applications

Obviousness Rationale

A person of ordinary skill would recognize the fundamental transferability of the drawer rear wall's structural principles to shipping container design. The core mechanical concept of a fastening system with multiple attachment points is readily adaptable to different transportation contexts. The PTD demonstrates predictable engineering extensions by applying the source patent's structural approach to cargo containment systems.

Obvious Combinations & Variations

Source Patent Element

Drawer rear wall with first and second fastening portions for sidewall attachment

PTD Variation

Adapting the fastening system to shipping container sidewalls

Obviousness Reasoning

Transferring attachment mechanisms between similar structural environments represents a standard design adaptation with predictable results

Source Patent Element

Metallic material construction specified in source patent claims

PTD Variation

Extending material selection to refrigerated and specialized transportation containers

Obviousness Reasoning

Material selection across similar structural applications is a routine design choice for a skilled engineer

Source Patent Element

Structural configuration with multiple attachment points

PTD Variation

Modular cargo management system using multiple drawer rear wall configurations

Obviousness Reasoning

Standardizing structural components across different vehicle types represents a predictable engineering optimization strategy

Source Patent Element

Wall thickness and material considerations

PTD Variation

Cargo restraint system integrated with drawer rear wall geometry

Obviousness Reasoning

Integrating structural components with cargo management systems is a logical extension of existing mechanical design principles

Source Patent Element

Drawer rear wall with spaced fastening portions

PTD Variation

Cargo capacity optimization through strategic wall placement

Obviousness Reasoning

Maximizing interior space through strategic structural design is a standard engineering problem-solving approach

35 U.S.C. § 103 Summary: Based on US Patent 11857072, the present publication demonstrates that a person having ordinary skill in mechanical engineering would find the disclosed shipping container and cargo management variations obvious through routine design adaptation. The technical variations represent predictable extensions of existing structural design principles, lacking inventive complexity sufficient to overcome an obviousness rejection under 35 U.S.C. § 103.
