Bumper Opening Cover With Tunable Elastic Removal Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bumper covers require excessive force and deformation for removal, leading to potential damage and difficulty in adjusting the required force for detachment.
Innovation Solution
A cover design featuring a first protrusion with an easily deformable portion and a support portion, allowing elastic deformation to securely attach to the bumper without large deformation or excessive force during removal, with a second protrusion that can be easily detached by inserting a tool between the cover and the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cover is designed with a rigid structure for stable attachment, then the attachment stability is improved, but the force required for removal becomes excessive and may cause damage
Solution Approach 1:
The first protrusion is segmented into a support portion and an easily deformable portion, allowing the structure to be divided into rigid and flexible sections. The support portion provides structural stability for attachment, while the easily deformable portion allows controlled deformation during removal, reducing the force needed and preventing damage to the rigid cover main body.
2Stability of the object's composition
If the cover requires deformation for removal, then the attachment stability is improved, but the ease of operation deteriorates due to difficulty in adjusting the removal force
Solution Approach 1:
The easily deformable portion allows for parameter changes in the deformation characteristics by adjusting its thickness, shape, or material properties. This enables the removal force to be tuned and optimized without changing the overall cover structure, improving ease of operation while maintaining attachment stability through the support portion.
3Ease of operation
If the cover main body is pushed to the bumper with excess force for removal, then the protrusions can be disengaged, but damage occurs to the cover or bumper
Solution Approach 1:
The easily deformable portion acts as an intermediary element between the cover main body and the opening. During removal, this intermediary portion deforms first to create space and reduce the force transmission to the cover main body and bumper, preventing direct excessive force contact and potential damage while still enabling successful disengagement of the protrusions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and damage-free removal of the cover from the bumper without large deformation or excessive force, with adjustable force requirements through varying the thickness and shape of the deformable portion.
Implementation Method 1
by an elastic deformation of the easily deformable portion to the another side by contacting the easily deformable portion to a hole edge of the opening

AI summary
A cover for a bumper opening, for closing the bumper opening formed in a bumper of a vehicle includes a cover main body, a first protrusion provided on one side of the cover main body and configured to be introduced into the opening, and a second protrusion provided on another side opposing the one side of the cover main body and configured to be introduced into the opening. The first protrusion includes a deformable portion which is deformably made, and a support portion for the deformable portion, and by an elastic deformation of the deformable portion to the another side by contacting the deformable portion to a hole edge of the opening, the second protrusion is closely contacted to the hole edge of the opening, and the cover main body is contacted to the bumper.
