Segmented Vehicle Door Guard with Replaceable Cushion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door guards for motor vehicles are expensive to manufacture and replace if damaged, and they do not adequately protect the front and rear bumpers from damage caused by adjacent vehicles during parking.
Innovation Solution
A multiple piece apparatus featuring deformable mounting components and resilient cushioning components that can be easily installed and replaced, providing protection for both doors and bumpers by wedging between the vehicle body and closure, and including a cushioned bumper guard for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one piece molded door guard is used, then satisfactory protection to the vehicle is provided, but the manufacturing cost increases due to expensive molds and replacement cost increases if vandalized or torn
Solution Approach 1:
The door guard is divided into multiple separate pieces (side pieces and end pieces) that can be individually manufactured and assembled. This segmentation allows for simpler, less expensive manufacturing processes for each component while maintaining the overall protective function, and enables partial replacement if only certain sections are damaged.
2Reliability
If conventional door guards are used, then some protection is provided, but they do not satisfactorily protect the front and rear bumpers
Solution Approach 1:
The door guard system is designed with multiple components (side pieces and end pieces) that can protect not only the door but also extend protection to the front and rear bumpers. The end pieces specifically engage with the bumper areas, providing multi-functional protection across different vehicle surfaces.
3Reliability
If a one piece door guard is used, then protection is provided, but it must be entirely replaced if vandalized or torn
Solution Approach 1:
The door guard is divided into multiple separate pieces (side pieces and end pieces) that can be individually manufactured and assembled. This segmentation allows for simpler, less expensive manufacturing processes for each component while maintaining the overall protective function, and enables partial replacement if only certain sections are damaged.
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
The solution effectively prevents door and bumper damage from adjacent vehicles with easy installation and replacement, reducing manufacturing and repair costs while offering comprehensive protection for all vehicle surfaces.
Implementation Method 1
The cushion section has an elongated shape and a resilient composition
Implementation Method 2
The mounting sections include a pair of deformable mounting components for securing to respective receptacles formed in opposite ends of the cushion section

AI summary
A multiple piece device for preventing damage to automotive vehicles includes a mounting section that is secured to the vehicle and a cushioning piece that is separate and distinct from and releasably attached to the support section. The support section itself may include one or multiple pieces that are fastened to the cushioning piece in various ways.
