Vehicle Rear Bumper Storage Case Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle storage structures inefficiently utilize the inner space of rear bumpers, leading to insufficient storage capacity and degraded functionality due to pollution and humidity in trunk rooms, and the rear bumper is not effectively used as a storage or step/bench.
Innovation Solution
A storage apparatus that draws out the inner space of the rear bumper to create additional storage, using a back beam for support and a sliding storage case with a tray cover and bumper cover that can function as a step or bench, along with a guide bracket and support bracket to manage load and prevent excessive extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the trunk lid is opened to access storage space, then stored goods can be stored, but the operation becomes complicated and time-consuming
Solution Approach 1:
The storage system is divided into multiple compartments including a first storage compartment accessible from the trunk room and a second storage compartment accessible from the rear bumper area. This segmentation allows different storage needs to be met without requiring full trunk lid opening, improving operational convenience while maintaining storage capacity.
Solution Approach 2:
The rear bumper is designed with dual functionality: it serves as both a protective bumper component and as an access door to the second storage compartment. This multi-functionality eliminates the need for separate access mechanisms, simplifying operation while preserving storage capacity.
2Quantity of substance
If the rear bumper inner space is used for storage, then storage capacity increases, but the bumper structure becomes more complex
Solution Approach 1:
The storage compartment structure is merged with the rear bumper assembly. The bumper cover, reinforcement members, and storage compartment walls are integrated into a single unified structure, reducing the need for separate components and simplifying the overall system while maximizing storage capacity within the bumper inner space.
Solution Approach 2:
The second storage compartment is nested within the rear bumper inner space, utilizing the available void volume efficiently. The reinforcement members and bumper cover are nested around the storage compartment, creating a compact integrated assembly that maximizes storage without proportionally increasing external dimensions or structural complexity.
3Ease of operation
If the rear bumper is used as a door for storage space, then access is simplified, but the spare space inside the bumper is not utilized
Solution Approach 1:
The rear bumper cover is designed as a movable component that can be opened independently to access the second storage compartment. This dynamic design allows the bumper to function as an access door while the inner space remains available for storage, simultaneously achieving operational convenience and space utilization without compromising either function.

AI summary
A storage apparatus for a vehicle may include a rear bumper having a back beam mounted under an inner space thereof, and a storage case provided in a space above the rear bumper, having a portion exposed to the outside formed so as to coincide with an outer surface of the rear bumper, and drawn-out/drawn-in by being slid to the outside in a state in which a load is supported above the back beam.
