Seat-Backrest Luggage Coupling for Easier Sports Car Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insertion of luggage in the luggage compartment of existing road cars is cumbersome and tiring due to the large size and weight of luggage and the small size of the passenger compartment, particularly in sports cars.
Innovation Solution
A storage system that allows luggage to be easily stored in the luggage compartment by coupling it to the seat backrest and the compartment using a combination of manual and electric motors, with detection devices to facilitate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If luggage is inserted through the hatch or dividing wall in known road cars, then the luggage compartment is accessible, but the operation becomes cumbersome and tiring due to large luggage size and weight combined with small passenger compartment space
Solution Approach 1:
The seat backrest is made movable between an upright position and a tilted position. When tilted, it creates a direct passage from the passenger compartment to the luggage compartment, allowing luggage to be easily transferred without manual lifting through the traditional hatch or dividing wall, thus resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The movable seat backrest acts as an intermediary element that facilitates luggage transfer. By tilting the backrest, it creates a temporary bridge or passage between the passenger and luggage compartments, enabling easy luggage insertion without requiring the luggage to be manually lifted through fixed openings
2Productivity
If the passenger compartment is kept small for sports car design, then the car maintains its sporty characteristics, but luggage insertion becomes more difficult due to limited space for maneuvering
Solution Approach 1:
The movable seat backrest dynamically changes the spatial configuration between compartments. When tilted, it efficiently utilizes the vertical space and creates a direct access path, enabling fast luggage storage despite the compact passenger compartment area typical of sports cars
3Ease of operation
If manual handling of heavy luggage is required, then no additional mechanical systems are needed, but user effort and fatigue increase significantly
Solution Approach 1:
The movable seat backrest reduces the vertical distance and effort required to transfer luggage. By tilting the backrest, it creates a more favorable angle and shorter path for luggage insertion, significantly reducing user physical effort compared to lifting through a fixed hatch or dividing wall

AI summary
A road car has a support frame (2); a passenger compartment (4) configured to accommodate, on the inside, at least a pair of seats (11) and a luggage compartment (12) obtained behind the seats (11); at least two access doors (10) to access the passenger compartment (4); at least one luggage item (16) configured to be stored in the luggage compartment (12); and a coupling unit (17) to connect the luggage item (16) and a backrest (14) of a relative seat (11) to one another in a releasable manner.
