Tri-Fold Pickup Cover Front Bar Fixing for Stable Full Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pickup truck covers suffer from instability in the connection of the front bar due to a single screw structure, and many cannot be fully opened, leading to inconvenience in accessing cargo.
Innovation Solution
A tri-fold semi-embedded cover with a front extension panel that includes a front bar, panel body, rotating shaft systems, locking system, support rod system, rear bar, guide rail, and front bar fixing system, featuring improved connection structures and adjustable components to enhance stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single screw structure is used to tighten the front bar to the car cover rail, then the device complexity is reduced, but the stability of the front bar connection end deteriorates
Solution Approach 1:
The front bar connection structure is segmented into multiple independent fixing points along its length. Instead of a single screw connection, multiple screws are distributed at different positions to connect the front bar with the car cover rail, dividing the connection function into several discrete attachment points that collectively provide enhanced stability
Solution Approach 2:
Multiple screw connections are merged along the front bar to create a distributed fixing system. The combination of several screw fastenings working together provides superior connection stability compared to a single screw, while maintaining relatively simple device complexity through the use of standard fastening components
2Device complexity
If a flat type cover is used, then the device complexity is reduced, but the ease of operation deteriorates because only two-thirds of the cover can be opened
Solution Approach 1:
The cover is segmented into multiple panels that can fold relative to each other. This segmentation allows the cover to be opened further than a single flat panel, improving accessibility to cargo while maintaining a relatively simple overall structure through the use of hinge connections between panels
Solution Approach 2:
The cover transitions from a static flat structure to a dynamic multi-panel folding structure. The panels can rotate and adjust their angles relative to each other, allowing the cover to open to a greater extent and providing better access to the cargo area while maintaining structural simplicity
