Telescopic Cargo Retention Frame with Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cargo management systems fail to efficiently accommodate varying sizes and types of cargo, as they lack adjustable frames that can securely hold and stabilize cargo during transport.
Innovation Solution
A cargo retention frame system comprising an outer and inner member that can slide and lock relative to each other, pivot about axes, and utilize snap-lock features to adjust aperture size, allowing for secure storage and stabilization of cargo through a combination of hinge systems, biasing members, and actuator mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size cargo frame is used, then the structure is simple and manufacturing is easy, but the system cannot accommodate varying sizes and types of cargo
Solution Approach 1:
The frame is divided into multiple telescoping sections with inner and outer members that can slide relative to each other. Each section can be independently adjusted to change the overall frame size, allowing accommodation of different cargo dimensions while maintaining a manageable structural complexity through modular design
Solution Approach 2:
The frame transitions from a static fixed-size structure to a dynamic adjustable structure through telescoping mechanisms. The inner and outer members are designed to slide relative to each other, enabling the frame to dynamically change its dimensions to match various cargo sizes while maintaining structural integrity through locking devices
2Adaptability or versatility
If an adjustable telescoping frame is implemented, then cargo of different sizes can be accommodated, but the mechanism for extending and retracting becomes complex
Solution Approach 1:
The telescoping frame incorporates spring-loaded biasing members that automatically provide the force needed for extension and retraction. When the locking device is released, the biasing members naturally push the inner and outer members to extend or retract, eliminating the need for complex motors or actuators and simplifying the operation to a simple lock-release action
Solution Approach 2:
The complex mechanical systems typically required for telescoping (motors, hydraulic cylinders, or multiple linkage mechanisms) are replaced with a simplified mechanical system using spring-loaded biasing members and a single locking device. This substitution maintains the adjustable functionality while dramatically improving ease of operation
3Adaptability or versatility
If the frame aperture is made adjustable to fit different cargo, then cargo stability may be compromised, but fixed aperture provides stable cargo holding
Solution Approach 1:
The frame is adjusted to match the cargo dimensions before cargo placement. The telescoping sections are extended or retracted to create an aperture that precisely fits the cargo, and the locking device is engaged to fix the frame in position. This preliminary adjustment ensures that the cargo is immediately stabilized upon placement, preventing movement during transport

AI summary
A vehicle cargo management system includes, among other things, an outer member of a cargo retention frame and an inner member of the cargo retention frame. The inner member is at least partially received within the outer member. A locking device is transitionable back and forth between a locked position and an unlocked position. The outer and inner members are slideable relative to each other when the locking device is in the locked position. The outer and inner members are fixed relative to each other when the locking device is in the unlocked position.
