Solution Overview

Problem

The existing video game seat designs are limited by the dimensions of straps and mounting points, making it difficult to adjust the folded-out position accurately, and require complex strap adjustments for varying the seat configuration.

Innovation Solution

A collapsible seat frame with a hinge that serves as a structural component, allowing frame parts to be subdivided into segments connected by load-bearing hinge bodies, and incorporates locking means for precise adjustment without straps, enabling flexible positioning and easier packaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If straps are used to determine the folded-out position, then the seat can maintain structural stability, but it becomes difficult to adjust the position accurately and requires complex strap adjustments

Engineering Contradiction:
Improveease of adjustmentVSAvoidcomplexity of strap adjustment
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent changes the fundamental parameter of position determination from strap length/tension to hinge angle. The hinge mechanism allows direct angular adjustment between frame parts, eliminating the need for strap length adjustments and providing precise positional control through simple angular changes at the hinge joint.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts the position determination function from the straps and relocates it to the hinge mechanism. The straps are reduced to merely supporting armrest functions, while the hinge takes over the primary role of defining the folded-out position through its locking mechanism, thereby simplifying the adjustment process.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If the frame is constructed as a single piece, then structural strength is maintained, but packaging becomes difficult due to large size

Engineering Contradiction:
Improveease of packagingVSAvoidstructural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent divides the frame into multiple separable components including the seat base, backrest, and console assembly, all connected through hinges. This segmentation allows each component to be folded or disassembled into compact forms for easy packaging, while the hinge connections maintain structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested folding mechanism where the console and control elements can be folded or nested within the frame structure. The hinge connections enable parts to be collapsed into each other, creating a compact packaged form factor similar to nested dolls, while maintaining full structural strength when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If straps function as armrests to bound the folded-out position, then structural stability is achieved, but entry and exit becomes difficult

Engineering Contradiction:
Improveease of entry and exitVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent extracts the armrest function from the position-bounding straps. The straps are reduced to solely providing structural support and position definition through the hinge mechanism, while dedicated armrest structures are provided that do not interfere with entry and exit, thereby improving accessibility while maintaining stability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Measurement precision

If the hinge allows free movement, then flexibility in positioning is achieved, but precise positioning becomes difficult

Engineering Contradiction:
Improveprecision of positionVSAvoidcomplexity of locking mechanism
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a dynamic locking mechanism in the hinge that allows free movement during adjustment and then locks securely at desired positions. The hinge transitions between a flexible state for positioning and a locked state for stabilization, providing precise positioning capability without requiring a permanently complex structure.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a seat (101), particularly for video games, comprising a collapsible frame (102) which carries a seat surface (109) and a backrest (104). The frame (102) comprises a first part (103) carrying the backrest (104) and a second part (105) configured to carry a console (107) for a steering wheel (117) or joystick for controlling a video game. These parts are connected pivotally to each other by means of a hinge (108). According to a first aspect of the invention, the hinge (108) comprises a first load-bearing body on which the first frame part (103) is mounted, and a second load-bearing body on which the second frame part (105) is mounted. According to a second aspect of the invention, the hinge (108) has locking means for fixating the first and second frame parts (103, 105) in a desired position relative to each other. The invention further relates to a hinge (108) for application in such a seat.
