Multi-level Rear Storage Shelf for Vehicle Trunk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle trunk storage systems are static, limiting the reconfiguration and utilization of space for items of varying sizes, which restricts efficient item placement and access.
Innovation Solution
A multi-level rear storage system with a shelf member that can transition between a retracted and extended configuration, allowing for increased surface area by dividing the storage volume into upper and lower compartments, and can be operated manually or automatically based on user input or environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static trunk storage volume is used, then the structure is simple and easy to manufacture, but the adaptability for different item sizes is limited
Solution Approach 1:
The shelf member is designed to be movable between a retracted position (near the rear floor) and an extended position (spaced apart from the rear floor), transforming the static storage system into a dynamic one that can adapt to different storage needs. This dynamic adjustment allows the storage volume configuration to change based on item sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The storage volume is segmented into an upper rear storage volume and a lower rear storage volume by the movable shelf member. This segmentation allows independent utilization of each compartment, enabling flexible accommodation of items with varying sizes and shapes, thereby improving adaptability without significantly increasing system complexity.
2Area of stationary object
If the shelf member is extended to create multi-level storage, then the surface area for item placement increases, but the device complexity increases
Solution Approach 1:
The shelf member's ability to move between retracted and extended positions dynamically adjusts the surface area available for item placement. When extended, it creates additional shelving surface and divides the storage space; when retracted, it maximizes the available floor area. This dynamic adjustment provides variable surface area without requiring multiple fixed shelves, thereby limiting the increase in device complexity.
3Adaptability or versatility
If the multi-level storage system is added, then the adaptability for different item configurations is improved, but the ease of operation decreases
Solution Approach 1:
The shelf member is designed to be manually movable between retracted and extended positions, allowing users to easily adjust the storage configuration themselves without requiring complex mechanical assistance or external help. This self-service design maintains ease of operation while providing improved adaptability for different item placement needs.

AI summary
A vehicle includes a rear door assembly having an open configuration that allows access to a rear storage volume and a closed configuration that inhibits access to the rear storage volume. A multi-level rear storage system is located in the rear storage volume. The multi-level storage system has a retracted configuration where a shelf member is relatively near a rear floor of the rear storage volume and an extended configuration with the shelf member spaced-apart from the rear floor thereby defining an upper rear storage volume above the shelf member and a lower rear storage volume below the shelf member.
