Vehicle Door Object Support With Moving Access Shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles lack a dynamic storage solution for objects, requiring passengers to manually carry and place items within stationary storage compartments, which is inconvenient during ingress and egress.
Innovation Solution
A door system with an object receiving portion that moves relative to the door's interior surface between accessible and storage positions, utilizing an actuator and controller to reposition the object support based on passenger input, allowing for convenient loading and unloading of items during entry and exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary storage compartment is used, then the structure is simple and reliable, but the accessibility and convenience for passengers during ingress and egress deteriorates
Solution Approach 1:
The object support is designed to move between a retracted position (when door is closed) and an extended position (when door is open), transforming a static storage solution into a dynamic one that adapts to different door states, thereby improving accessibility without permanently increasing structural complexity
Solution Approach 2:
The object support serves multiple functions: it acts as a storage surface when retracted and as an accessible loading surface when extended, allowing a single component to fulfill both storage and accessibility needs across different operational states
2Volume of stationary object
If an object support extends outwardly when door is closed, then storage capacity is improved, but the risk of contact with vehicle body and potential damage increases
Solution Approach 1:
The object support dynamically adjusts its position based on door state - remaining retracted when the door is closed to avoid contact with the vehicle body, and only extending when the door is open, thereby eliminating the harmful contact while maintaining storage capacity when needed
3Productivity
If manual handling of objects is required, then the device complexity is reduced, but the productivity and convenience of loading/unloading deteriorates
Solution Approach 1:
The object support system performs self-service by automatically extending and retracting based on door position detection, eliminating the need for manual intervention to position the support, thereby improving loading/unloading efficiency without requiring complex manual operation mechanisms
4Ease of operation
If the object support moves with door opening, then accessibility during egress is improved, but the reliability of object retention may deteriorate
Solution Approach 1:
The object support moves dynamically with the door - extending during door opening to provide accessibility during egress, and retracting when the door is closed to maintain stable object retention in the protected storage position, thereby balancing accessibility and retention reliability across different states
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
Enhances passenger convenience by allowing objects to be easily loaded and unloaded without manual handling, optimizing storage and accessibility within the vehicle, while preventing contact between the object support and the vehicle body during door operation.
Implementation Method 1
a magnet coupled to the object receiving portion and configured to magnetically retain the object to the object receiving portion
Implementation Method 2
a case comprising a magnet having a first polarity. The object receiving portion comprises a ferrous material or a magnetic material having a second polarity, opposite the first polarity, with the case configured to be magnetically retained to the object receiving portion
Data Source
AI summary
An object support includes an object receiving portion extending from a panel and configured to support an object, with the object receiving portion configured to move relative to an interior surface between a first position when the panel is in a closed position and a second position when the panel is in an open position. The object receiving portion is closer to a lateral surface of the panel in the second position than the first position.
