Solution Overview

Problem

Conventional vehicles lack effective separation of passenger spaces, particularly between left and right seats, and struggle to maintain vehicle body stiffness and collision stability with a skateboard type floor, which is addressed by forming a vehicle body using a combination of seat frame members at the upper end of a skateboard type vehicle floor to create independent passenger spaces with individual air conditioning and display systems.

Innovation Solution

The vehicle body is formed by coupling seat frame members to the floor portion, with a main roof member connecting between them, providing annular pillars, individual air conditioning ducts, and adjustable displays, along with auxiliary partitions and storage solutions, to create independent and comfortable passenger spaces while maintaining vehicle stiffness and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a large console is centrally disposed in the vehicle interior to separate front and rear seat spaces, then space separation between front and rear seats is achieved, but the console occupies a large portion of the interior and space utility is degraded

Engineering Contradiction:
Improvespace separationVSAvoidinterior space
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The vehicle interior is segmented into multiple independent passenger spaces using partition walls between left and right seats, as well as between front and rear seats. This segmentation achieves space separation without requiring a large central console, as the partitions are integrated with the seat frame structure rather than being separate overhead components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seat frame members serve multiple functions: they provide structural support for the seats, form the vehicle body framework, and integrate with partition walls to create space separation. This multi-functionality eliminates the need for separate dedicated space-separation components like large central consoles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a skateboard type floor is used for vehicle electrification, then various vehicle types can be manufactured, but it is difficult to secure vehicle body stiffness and collision stability without a large number of additional members

Engineering Contradiction:
Improvevehicle type flexibilityVSAvoidvehicle body stiffness
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The seat frame members are merged with the vehicle body framework, where the same structural components that support the seats also provide the rigid framework for the entire vehicle body. This integration eliminates the need for separate additional members to achieve stiffness, as the seat frames themselves form the load-bearing structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The seat frame members perform dual functions as both seat support structures and vehicle body framework elements. This multi-functionality allows the skateboard platform to achieve the same stiffness and collision stability as conventional vehicles with dedicated chassis members, without requiring additional components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If conventional seat mounting is used on a skateboard floor, then seats can be installed, but vehicle body stiffness and collision stability cannot be maintained without numerous additional members

Engineering Contradiction:
Improveseat mountingVSAvoidcollision stability
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The seat mounting structure is merged with the vehicle body framework, where the seat frame members are directly integrated into the load-bearing structure. This integration ensures that the same components providing ease of seat installation also contribute to collision stability, eliminating the need for separate reinforcement members.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vehicle body of a vehicle may include a floor portion which is provided for a driving unit of the vehicle to be mounted therein, and a seat frame member mounted with a seat of the vehicle while being selectively coupled to a plurality of points on the floor portion, to form the vehicle body, for achieving seat mounting and vehicle body configuration.
