Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-up truck cargo box covers face issues such as air turbulence, noise, reduced fuel efficiency, lack of security, exposure to weather, and difficulty in installation, as well as leakage and corrosion problems.
Innovation Solution
A lightweight, durable, and rigid cargo box cover assembly with foldable panels and a releasable latch system that attaches to side rails, providing a secure and water-resistant barrier while allowing easy access to the cargo box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a rigid cover is used to reduce drag and improve fuel economy, then aerodynamic performance improves, but the cover becomes difficult to open and access cargo becomes difficult
Solution Approach 1:
The cover is divided into multiple panels (typically four panels) that can be independently folded back. Each panel is hinged to allow sequential folding, enabling the cargo box to be accessed in sections while maintaining the aerodynamic profile when closed.
Solution Approach 2:
The cover transitions from a static rigid structure to a dynamic folding structure. The panels can be folded back along hinge lines to create openings for cargo access, while returning to a flat closed position for aerodynamic efficiency. This dynamic capability resolves the contradiction between maintaining drag reduction and enabling cargo access.
2Ease of manufacture
If a simple canvas or vinyl cover is used, then installation is easy, but the cover leaks and allows rain to enter the box
Solution Approach 1:
The cover uses composite construction with rigid panels (metal, fiberglass, or plastic) providing structural integrity and weather resistance, combined with flexible sealing elements (rubber or plastic seals) at the edges and hinge joints to prevent water infiltration while maintaining durability and water-tightness.
3Reliability
If a metal or fiberglass cover is used to provide durability and security, then protection from theft and weather improves, but the cover becomes time-consuming and difficult to install
Solution Approach 1:
The cover is segmented into multiple panels connected by hinges, allowing modular assembly. The side rails attach to the box first, then panels are sequentially connected and secured with latches, simplifying the installation process while maintaining the structural integrity and security of a rigid construction.
Solution Approach 2:
The cover incorporates self-aligning features and tool-free latch mechanisms that enable easy installation and removal by the user without requiring specialized tools or complex alignment procedures, reducing installation time while maintaining security.
4Ease of operation
If a cover with multiple panels and hinges is used to allow partial opening for access, then cargo accessibility improves, but the device complexity increases
Solution Approach 1:
The cover is divided into a limited number of panels (typically four) with simple hinge connections, allowing selective opening of individual sections for cargo access while maintaining overall structural simplicity and ease of operation.

AI summary
A cover assembly for a pick-up truck cargo box includes first and second rails attachable at the sides of the box. A cover has a first resilient hinge strip connecting a first panel to a second panel and allowing the first panel to pivot relative to the second panel. A third panel is attached to the second panel by a second resilient hinge strip, which allows the second panel to pivot relative to the third panel. The panels are supported on the rails. Latches on the panels hold the panels onto the rails. The cover may be opened by sequentially releasing the latches and folding the panels over onto each other.
