Segmented Liftgate Assembly for Selective Cargo Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liftgates in SUVs are cumbersome and slow to open and close, and there is a need for controlled access to the rear compartment without opening the entire liftgate, especially for multiple secure storage areas.
Innovation Solution
A multi-way liftgate assembly with multiple access doors and dividers that allow selective access to multiple compartments, enabling rapid opening and closing of smaller doors and trays for enhanced control over cargo placement and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire liftgate is opened to access the rear compartment, then full access to the cargo area is achieved, but the operation becomes slow and requires more effort
Solution Approach 1:
The liftgate is divided into multiple independent access doors (left access door, right access door, and central access door) that can be opened separately. Each door provides access to specific compartments, allowing users to open only the necessary portion rather than the entire liftgate, thereby improving access speed and reducing effort while maintaining security for closed compartments.
2Productivity
If the entire liftgate is opened to access the rear compartment, then full access is achieved, but time is lost opening and closing the large door
Solution Approach 1:
The liftgate system incorporates multiple smaller access doors (left, right, and central doors) that can be opened independently and more quickly than a single large liftgate. This segmentation allows for rapid access to specific compartments without the time penalty of maneuvering and securing a large entire liftgate assembly.
3Adaptability or versatility
If the rear cargo area is divided into multiple secure areas, then controlled access is improved, but the device complexity increases
Solution Approach 1:
The rear cargo area is divided into multiple secure compartments (first, second, and third compartments) accessible through separate doors. Each door can be independently locked or unlocked, providing granular control over which compartments are accessible at any given time. This segmentation enables the vehicle operator to control access to specific portions of the cargo area while maintaining security for other portions.
Solution Approach 2:
The liftgate assembly incorporates movable dividers (first and second dividers) that can be repositioned to dynamically change compartment configurations. These dividers allow the cargo area to be adaptively segmented based on loading needs, providing versatility in access control and storage organization while maintaining a manageable structural complexity through standardized moving components.

AI summary
A multi-way liftgate assembly providing a plurality of dividers dividing the rear cargo area of a passenger vehicle into a plurality of secure areas assessable from a plurality of panels forming a liftgate to provide controlled access to one or more of those compartments. The vehicle operator has secure control of which portions of the cargo area can be selectively accessed. The multi-way liftgate assembly provides multiple secure openings to the cargo area of a vehicle that typically has only one secure opening to the cargo area.
