Multi-Way Liftgate Assembly for Selective Secure Cargo Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sport utility vehicles with liftgate doors face challenges in accessing the rear compartment efficiently, as existing liftgates are heavy, slow to open and close, and lack controlled access to multiple secure areas within the cargo area.
Innovation Solution
A multi-way liftgate assembly that divides the rear cargo area into multiple secure compartments, allowing controlled access through sub-rear end compartment-sized liftgate access doors that can be opened independently or automatically, with sliding cargo trays and dividers for secure and efficient cargo management.
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 time-consuming
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. This segmentation allows users to open only the necessary portion of the liftgate for their cargo needs, rather than opening the entire liftgate, thereby reducing operation time and improving access efficiency.
2Productivity
If the liftgate is designed for rapid access, then opening speed improves, but controlled access to multiple secure areas is lost
Solution Approach 1:
The cargo area is divided into multiple secure compartments (first secure compartment, second secure compartment, third secure compartment) corresponding to different access doors. Each compartment can be accessed independently through its designated door, enabling both rapid access when needed and controlled access when security is required. The system provides versatility by allowing selective access to one or multiple compartments based on user needs.
Solution Approach 2:
The liftgate system transitions from a static single-door design to a dynamic multi-door configuration where each door can be independently operated. This dynamic design allows the system to adapt between rapid full access (opening all doors) and controlled selective access (opening only specific doors to specific compartments), providing both speed and security flexibility.
3Adaptability or versatility
If a multi-way liftgate assembly with multiple dividers is implemented, then controlled access to multiple compartments is achieved, but device complexity increases
Solution Approach 1:
The liftgate assembly is segmented into modular components (multiple access doors, multiple dividers, multiple secure compartments) that can be independently configured. This modular segmentation manages complexity by breaking down the complex multi-access system into manageable, standardized units that can be systematically arranged to create different compartment configurations as needed.

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.
