Solution Overview

Problem

Existing vehicle seats often have seat bottoms that are difficult to remove, making it cumbersome to access areas beneath the seat for storage compartments or cleaning purposes.

Innovation Solution

A seating system with a removable seat cushion featuring a handle integrated into the cushion's projecting portion, allowing easy grasping and manipulation for access to spaces below the seat, including storage compartments or for cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the seat bottom is made without a handle, then the structure is simpler and manufacturing is easier, but the seat bottom becomes difficult to grasp and remove

Engineering Contradiction:

Improveease of manufactureVSAvoidease of removal

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The handle is merged with the seat cushion by forming it as an integrated projecting portion of the cushion itself. This combines the structural support function of the cushion with the gripping function of the handle, eliminating the need for separate handle components while maintaining ease of removal.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The seat cushion serves multiple functions: it provides seating support for the occupant and simultaneously serves as its own handle through the projecting portion. This multi-functional design allows the same structure to fulfill both comfort and manipulation requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If the seat bottom is made without a handle, then there are fewer components and device complexity is reduced, but the seat bottom becomes cumbersome to manipulate

Engineering Contradiction:

Improvedevice complexityVSAvoidease of manipulation

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The handle function is merged into the seat cushion structure itself through the projecting portion, eliminating the need for separate handle components. This reduces device complexity while maintaining ease of manipulation through the integrated gripping surface.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the handle is formed in the projecting portion of the seat cushion, then the seat cushion is easier to grasp and remove, but the cushion structure becomes more complex

AI summary

A vehicle seat includes a seat back and a seat cushion supported on a frame. The seat cushion is removable from the frame to allow access to an area beneath the seat. The seat cushion includes a cushion member forming a seating surface. A handle is formed on the cushion member to facilitate grasping the seat cushion to allow the seat cushion to be removed from the frame.
