Solution Overview

Problem

In organized seating arrangements, such as in transportation vehicles and auditoriums, unoccupied adjacent seats can lead to reduced comfort for occupants due to unused space, as existing seats are not easily adaptable to optimize the use of available space.

Innovation Solution

A transformable seat assembly with a hinge and torsion spring mechanism that allows the seat to rotate and recline, enabling the seat to extend away from the support structure, thereby optimizing the use of adjacent space by allowing occupants to utilize unoccupied adjacent seats for additional comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the seat is designed as a fixed structure, then the structural simplicity is maintained, but the adaptability to optimize space usage is reduced

Engineering Contradiction:
ImproveadaptabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seat is designed with dynamic components including a hinge mechanism allowing rotation between upright and reclined positions, and a transformable support structure that can extend or retract. This enables the seat to adapt to different spatial configurations and optimize space usage while maintaining structural feasibility through standardized mechanical components

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the seat is designed to rotate and extend, then the space optimization capability is improved, but the device complexity increases

Engineering Contradiction:
Improvespace optimization capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The seat is divided into separable modules including the seat cushion, backrest, hinge mechanism, and transformable support structure. This segmentation allows each component to perform its specific function independently, simplifying the overall design and making the complex transformation capabilities more manageable through modular assembly

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the lumbar cushion is permanently attached, then the structural stability is maintained, but the ease of transformation is reduced

Engineering Contradiction:
Improveease of transformationVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The lumbar cushion is designed with a dynamic attachment system that allows it to be easily removed and reattached. This enables the cushion to accommodate different seat configurations during transformation while maintaining structural stability when attached, and facilitating easy transformation when removed

Inventive Principle:
Principle #15Dynamics

AI summary

A transformable seat assembly which includes a seat support structure and a seat connected to the seat support structure with a hinge. The hinge defines an axis of rotation. A back support structure connected to the seat support structure, which extends in an upward direction relative to the seat support structure. A back cushion is secured to the back support structure and a lumbar cushion extends along the back support structure positioned between the back cushion and the seat, wherein the lumbar cushion is releasably secured to one of the back cushion or the back support structure and an end portion of the seat positioned closer to the back support structure with the seat positioned in an occupant support position than the hinge, can rotate in a direction of rotation about the axis of rotation, which includes the upward direction and a direction away from the back support structure.
