Below-floor Baggage Storage with Shock-absorbing Seat Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baggage storage devices for moving objects, such as vehicles, hinder the reciprocating motion of seats when installed between the seat and floor, preventing their installation below the seat, which limits the ability to store baggage effectively.
Innovation Solution
A moving object design featuring a storage portion located below the seat, utilizing a shock absorber to allow vertical reciprocating motion and a displacement restriction portion to prevent baggage from coming out, with a detection sensor and notification system to ensure passengers retrieve their luggage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a baggage storage device is installed between the seat and floor, then baggage storage is enabled, but the seat's vertical reciprocating motion is hindered
Solution Approach 1:
The storage portion is repositioned from the vertical space between seat and floor to the horizontal space below the floor surface. This dimensional transition allows the storage function to coexist with the seat's vertical reciprocating motion, as the storage space is located in a different spatial plane that does not interfere with the seat's movement range.
Solution Approach 2:
The storage portion is divided into multiple compartments (first storage portion and second storage portion) located at different positions below the floor surface. This segmentation allows the storage system to be distributed in space rather than concentrated in a single location that might interfere with seat motion.
2Ease of operation
If storage portion is located below the floor surface, then seat motion is maintained, but baggage retrieval requires passing through floor opening
Solution Approach 1:
A movable platform is introduced as an intermediary mechanism between the storage portion and the passenger. The platform can be lowered from the floor surface to the storage portion level, allowing passengers to retrieve baggage without directly accessing the below-floor storage space. This mediator simplifies the retrieval process while maintaining the benefits of below-floor storage.
Solution Approach 2:
The movable platform system enables automatic or semi-automatic baggage retrieval where the platform can be activated to lower to the storage level, allowing passengers to independently access their baggage without complex manual intervention or assistance from crew members.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and safe storage of baggage beneath the seat, maintaining the seat's vertical motion and preventing luggage loss by using a displacement restriction and notification system.
Implementation Method 1
Each of the plurality of seats (38) includes a shock absorber (42). The shock absorber (42) absorbs a load applied to a seat portion (381) by causing the seat portion (381) to make reciprocating motion in a vertical direction (Y).
