Expandable Vehicle Door Guard with Servo-Driven Vertical Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door guards only protect against objects at the height of the guard, failing to provide comprehensive protection against all potential damage sources without compromising the vehicle's appearance.
Innovation Solution
An extendable and retractable door guard system with a servomotor and gear train mechanism that allows guard panels to pivot and extend vertically, providing increased coverage when needed, controlled via a key fob-like device or dashboard interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional door guards are used, then protection against objects at guard height is provided, but comprehensive protection against all damage sources is not achieved
Solution Approach 1:
The door guard system transitions from a static conventional design to a dynamic multi-position system that can extend vertically to cover different height ranges. The guard panels can be positioned at multiple vertical locations along the door surface, allowing the same device to protect against objects at various heights by adjusting the panel positions.
Solution Approach 2:
The door guard is divided into multiple separate panels that can be independently positioned and adjusted. This segmentation allows each panel to be placed at optimal vertical positions to cover different threat zones, providing comprehensive protection while maintaining a compact form when not in use.
2Object-affected harmful factors
If a door guard covers the entire exterior surface of the car door, then comprehensive protection is achieved, but the appearance of the vehicle is negatively impacted
Solution Approach 1:
The door guard system transitions from a static conventional design to a dynamic multi-position system that can extend vertically to cover different height ranges. The guard panels can be positioned at multiple vertical locations along the door surface, allowing the same device to protect against objects at various heights by adjusting the panel positions.
Solution Approach 2:
The protective function is extracted from a permanent full-surface covering and implemented as a compact, deployable system. When retracted, the guard panels are concealed or minimized in appearance, and only extend to provide protection when needed, thus preserving the vehicle's aesthetic appearance while maintaining comprehensive protection capability.
3Adaptability or versatility
If conventional door guards are used, then installation simplicity is maintained, but adaptability to different threat heights is limited
Solution Approach 1:
The door guard system transitions from a static conventional design to a dynamic multi-position system that can extend vertically to cover different height ranges. The guard panels can be positioned at multiple vertical locations along the door surface, allowing the same device to protect against objects at various heights by adjusting the panel positions.
Solution Approach 2:
The door guard system is designed to perform multiple protective functions across different vertical zones of the door. A single device configuration can protect against threats at various heights by deploying panels to different positions, making the system universally applicable to diverse parking lot threats without requiring multiple separate guards.

AI summary
A door guard that is adapted to extend and retract as desired by the user is provided. The present door guard comprises a motor disposed within the interior portion of an automotive vehicle side door and an expandable guard assembly disposed on the exterior portion of an vehicle door. The motor is connected to a control unit, which allows the user to vertically expand and retract the guard assembly as desired.
