Foldable Chair With X-Frame Locking for Compact Gaming Storage

Solution Overview

Problem

Conventional racing game seats are large and heavy, making them impractical for use at home due to their size and weight, which limits their portability and storage convenience.

Innovation Solution

A foldable chair design featuring a first and second bracket hingedly fixed in an X-shape with an adjusting mechanism that includes a fixing member with a slide groove and a movable limit member, allowing for easy folding and unfolding, and adjustable unfolding degrees, along with a rotatable third bracket and seat cover for enhanced usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional racing game seats are designed to provide comfortable gaming experience, then seating comfort is improved, but the seats become large and heavy, making them difficult to store and transport

Engineering Contradiction:

Improveseating comfortVSAvoidseat weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The chair is divided into multiple detachable components including seat, backrest, armrests, and base, allowing the user to separate and store only the necessary parts. This segmentation enables the chair to provide full seating comfort when assembled while reducing storage space and effective weight when disassembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The chair incorporates adjustable components including height-adjustable seat and backrest, rotatable armrests, and collapsible legs with locking mechanisms. These dynamic features allow the chair to adapt to different user preferences and positions while maintaining a compact form when folded or disassembled.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If conventional racing game seats are designed to provide comfortable gaming experience, then seating comfort is improved, but the seats become large and bulky, making them difficult to store

Engineering Contradiction:

Improveseating comfortVSAvoidseat volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The chair is divided into multiple detachable components including seat, backrest, armrests, and base, allowing the user to separate and store only the necessary parts. This segmentation enables the chair to provide full seating comfort when assembled while reducing storage space and effective weight when disassembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The chair features a nesting design where the seat can be placed inside the backrest, and armrests can be stored within the seat structure. This nested configuration significantly reduces the volume occupied during storage while maintaining full functionality when assembled.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of operation

If the chair structure is made foldable to improve portability, then ease of storage is improved, but the structural complexity increases

Engineering Contradiction:

Improveease of storageVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The chair is divided into multiple detachable components including seat, backrest, armrests, and base, allowing the user to separate and store only the necessary parts.
