Tiltable Door Storage for Mobility Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric personal mobility devices occupy a large volume in vehicle trunks and require users to bend when removing them, causing inconvenience due to their size and weight.
Innovation Solution
A mobility device storage apparatus for vehicles that incorporates a door with a storage space and a tiltable storage device, where the tiltable storage device is rotatable in a lateral direction and restricted from vertical tilting by a tilting-up locking portion, allowing easy removal of the device without bending by releasing the locking mechanism when rotated laterally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric personal mobility device is stored in the trunk compartment or back seat, then the device can be stored, but it occupies a large volume and requires the user to bend at the waist to remove it
Solution Approach 1:
The patent moves the storage location from the traditional horizontal trunk compartment to the vertical door structure. The storage box is mounted on the door panel, utilizing the vertical dimension and door space that would otherwise be unused. This dimensional shift allows the mobility device to be stored at an elevated position, eliminating the need for users to bend at the waist while removing the device, thus resolving the contradiction between ease of operation and vehicle internal volume utilization.
2Ease of operation
If the storage box is made tiltable for easy removal, then user convenience is improved, but the structure becomes more complex requiring locking mechanisms
Solution Approach 1:
The storage box is designed with tiltable functionality, transitioning from a static to a dynamic structure. The box can rotate between a horizontal storage position and a tilted removal position, allowing users to easily extract the mobility device by tilting the box forward. This dynamic design improves ease of operation while the complexity is managed through a relatively simple hinge and locking mechanism system.
Solution Approach 2:
The locking mechanism is designed to automatically lock when the storage box is in the tilted position, preparing the system in advance for safe removal. The position releasing portion and tilting-up locking portion work together to maintain the tilted position securely, so that when the user pulls the mobility device, the box remains stable and locked in the convenient tilted orientation without requiring continuous manual adjustment.
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
The solution allows for efficient use of vehicle space by storing the device in the door, enabling easy and convenient removal of the mobility device without straining the user, as the device can be tilted upward and removed directly from the door.
Implementation Method 1
a first torsion spring connected to the rotation shaft wherein the tilting portion is rotated with the rotation shaft in the lateral direction by an elastic force of the first torsion spring
