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. 11,857,082.

Background and Problem Solved

The original seating furniture chassis patent disclosed a design with releasably fastenable back and side parts. However, the assembly process was prone to errors, and the fastening mechanism lacked security features. The present invention addresses these limitations by introducing self-aligning and locking mechanisms, ensuring a more efficient and reliable assembly process

Novelty and Inventive Step

The present invention's novelty lies in the integration of self-aligning and locking mechanisms into the seating furniture chassis, which significantly improves the assembly process and ensures secure fastening. The inventive step resides in the combination of these features, providing a more efficient, reliable, and user-friendly design

Alternative Embodiments and Variations

Alternative embodiments of the invention may include different types of sensors or locking mechanisms, adjustable self-aligning mechanisms, or various visual indicators. Additionally, the invention could be adapted for use in different types of seating furniture, such as office chairs or sofas

Potential Commercial Applications and Market

The enhanced seating furniture chassis has significant commercial potential in the furniture manufacturing industry, particularly in the production of high-end office chairs and luxury sofas. The invention's improved assembly process and enhanced user experience can lead to increased customer satisfaction, reduced production costs, and a competitive edge in the market

▼

Field of Art

Furniture design and mechanical engineering, specifically seating furniture chassis with modular assembly and electrical integration

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer with expertise in furniture design, familiar with modular assembly techniques, electrical cable management, and ergonomic furniture component integration

Obviousness Rationale

A person of ordinary skill would recognize that adding self-aligning and locking mechanisms to a modular seating chassis represents a predictable engineering solution to improve assembly reliability. The source patent establishes a foundational modular chassis design, and the PTD's variations represent straightforward mechanical enhancements that solve known assembly challenges. These modifications would be considered routine design optimization within the technical capabilities of a skilled practitioner.

Obvious Combinations & Variations

Source Patent Element

Releasably fastenable back part and side parts

PTD Variation

Self-aligning mechanism integrated into the fastener to facilitate easier assembly

Obviousness Reasoning

Adding self-alignment to modular connections is a known technique to improve component mating, representing a predictable solution to reduce assembly complexity

Source Patent Element

Electrically conductive cables fastened to base body

PTD Variation

Sensor to detect back part presence and automatically lock it in place

Obviousness Reasoning

Integrating electronic sensing with mechanical locking is a standard approach in modern furniture design, representing an obvious combination of known techniques

Source Patent Element

Modular chassis with releasable components

PTD Variation

Visual indicator to signal proper fastening of back part

Obviousness Reasoning

User feedback mechanisms are common in modular designs to confirm correct assembly, representing a predictable design choice for improving user interaction

Source Patent Element

Base body with multiple electrical connectors

PTD Variation

Locking mechanism to prevent accidental detachment of back part

Obviousness Reasoning

Safety and reliability improvements through mechanical locking are standard engineering practices, particularly in furniture with multiple removable components

Source Patent Element

Seating furniture with peripheral electrical devices

PTD Variation

Alternative embodiments with adjustable self-aligning mechanisms

Obviousness Reasoning

Designing multiple implementation variants of a core mechanical concept is a routine engineering approach to expand design flexibility

35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11857082, the variations disclosed herein would be obvious to a person having ordinary skill in the art of furniture design. The incremental mechanical and electronic enhancements represent predictable solutions to known assembly challenges, and therefore fail to demonstrate non-obvious subject matter under 35 U.S.C. Section 103.
