Facing Seats Automated Driving Vehicle Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Facing seats-type automated driving vehicles face challenges in being compact while accommodating both passengers and luggage, particularly in accommodating multiple passengers and variously-shaped luggage efficiently.
Innovation Solution
The vehicle design includes facing seats with variable structures and elongation structures for the seats and luggage decks, allowing the front and rear seats, backrests, and luggage decks to be rearranged to optimize space, with shorter lengths and higher heights for the luggage decks than the floor deck, enabling more efficient use of space for both passengers and luggage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vehicle is designed to accommodate multiple passengers and luggage, then the passenger capacity and luggage capacity are improved, but the vehicle size increases
Solution Approach 1:
The patent elevates the luggage deck above the floor deck upper surface, utilizing the vertical space between the floor deck and the vehicle roof. This dimensional transition from horizontal to vertical space utilization allows the vehicle to accommodate more luggage without increasing the horizontal footprint, thereby resolving the contradiction between luggage capacity and vehicle size.
Solution Approach 2:
The patent employs variable seat structures that can change position and configuration. The seats can be adjusted, folded, or reconfigured to create additional space for passengers or luggage as needed, allowing the vehicle to dynamically adapt its interior space to meet different transportation needs without permanently increasing its size.
2Adaptability or versatility
If the vehicle is designed to accommodate variously-shaped luggage, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The variable seat structures allow the vehicle interior to be dynamically reconfigured to accommodate different luggage shapes and sizes. By adjusting seat positions, folding seats, or changing seat configurations, the vehicle can adapt to various luggage arrangements without requiring complex dedicated compartments for each luggage type.
Solution Approach 2:
The elevated luggage deck and variable seat system serve multiple functions: they can accommodate different types of luggage (various shapes and sizes), provide passenger seating, and create flexible cargo spaces. This multi-functionality reduces the need for specialized structures for each luggage type, thereby managing complexity while maintaining high adaptability.
3Length of moving object
If the luggage deck is made shorter in the vehicle front-rear direction, then the vehicle length is reduced, but the luggage capacity decreases
Solution Approach 1:
The patent compensates for the reduced horizontal length of the luggage deck by utilizing vertical space. The luggage deck is positioned above the floor deck upper surface, allowing luggage to be stacked or arranged vertically. This vertical arrangement maintains luggage capacity despite the shorter horizontal dimension, thereby reducing overall vehicle length without sacrificing luggage capacity.

AI summary
An automated driving vehicle, including facing seats, a floor deck and a luggage deck. The facing seats includes a front seat assembly having at least a front seat and a front backrest, and a rear seat assembly having at least a rear seat and a rear backrest, the front and rear seat assemblies being disposed to cause the seated passengers to respectively face rearward and forward directions of the vehicle. The floor deck is provided to allow the passengers to rest their feet, the floor deck having no level difference. The luggage deck is for at least one piece of luggage to be placed thereon, and includes a front luggage deck disposed forward of a front end of the floor deck in the forward direction of the vehicle, and a rear luggage deck disposed rearward of a rear end of the floor deck in the rearward direction of the vehicle.
