Rear Bumper Cover with Top Stabilizing Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bumper protection devices are cumbersome, complicated, and time-consuming to install, and often suffer from curling, flapping, and twisting issues, which leave the rear bumper unprotected and can obscure advertisements.
Innovation Solution
A hanging rear bumper protective device with a base layer of flexible material and stabilizing blocks that reduce curling, featuring a secure attachment system to the vehicle, eliminating the need for bottom weights and ensuring easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bottom weight is added to prevent flapping, then wind-induced flapping is reduced, but the device becomes prone to twisting or rotational motion and the installation becomes more complex
Solution Approach 1:
The stabilizing function is segmented from the bottom weight concept and distributed to multiple stabilizing blocks positioned at the top portion corners. This segmentation allows the cover to achieve stability without the complexity of bottom weights, preventing both flapping and twisting through distributed top-level anchoring points.
Solution Approach 2:
Instead of weighting the bottom edge to prevent flapping, the invention inverts the approach by placing stabilizing blocks at the top portion. This inversion prevents flapping through top-level stabilization rather than bottom-level weighting, eliminating the twisting problem associated with bottom weights.
2Stability of the object's composition
If stabilizing blocks are added to the top portion, then curling is reduced, but the device complexity increases
Solution Approach 1:
The stabilizing blocks are merged with the attachment system at the top portion. The blocks serve dual functions as both structural stabilizers and attachment points for securing means, combining multiple functions into a single integrated component rather than adding separate elements.
Solution Approach 2:
Stabilizing blocks are placed specifically at the corner regions of the top portion where curling forces are most concentrated. This localized placement provides maximum anti-curling effect with minimal additional structure, rather than uniformly reinforcing the entire top edge.
3Reliability
If existing protection devices are used, then bumper protection is provided, but installation is time-consuming and cumbersome
Solution Approach 1:
The stabilizing blocks and attachment means are pre-integrated into the cover structure during manufacturing. This preliminary assembly eliminates the need for complex field installation procedures, allowing users to simply attach the pre-configured cover to the bumper without time-consuming assembly steps.
Solution Approach 2:
The attachment means is designed with universal adaptability to fit various bumper types and configurations. This multi-functionality allows a single cover design to be installed on different vehicle models without requiring model-specific components or complex adjustment procedures.

AI summary
A rear bumper protective device containing (i) a base layer of hanging flexible material having a top portion, side portions, and a bottom portion, and having a construction and thickness capable of reducing or preventing damage to a rear portion of a vehicle, and being of sufficient dimensions to at least partially cover a rear portion of a vehicle; and (ii) one or more stabilizing blocks protruding from the top portion of the base layer and positioned colinearly with or along a contour edge of the top portion and being of sufficient rigidity, thickness, width, and length to reduce curling of the rear bumper protective cover. The bumper protective device can include one or more securing features capable of attaching to a rear portion of a vehicle.
