Vehicle Back Door Shielding Plate for Easier Luggage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shielding plate designs in vehicles, particularly in coupe sport utility vehicles, are inconvenient for placing or removing articles due to their connection structure, leading to potential noise during driving and inefficient use of luggage compartment space.
Innovation Solution
A back door design where the rear shielding plate is connected and fixed to the back door, allowing it to move integrally with the door, enabling direct access to articles in the luggage compartment without operating the shielding plate, and forming a shielding plate when closed, with a detachable connection system for ease of assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shielding plate is divided into foldable sections connected by hanging ropes, then the shielding plate can be lifted when the back door is opened, but it is inconvenient to take or place articles on the fixed section and may generate abnormal sound during driving
Solution Approach 1:
The shielding plate is divided into a fixed section and a movable section. The fixed section remains stationary and provides stable article storage, while the movable section can be independently opened or closed to provide access to articles without moving the entire shielding plate, eliminating noise during driving while maintaining ease of access.
Solution Approach 2:
The shielding plate incorporates a movable section that can dynamically change position between open and closed states, allowing users to access articles without opening the back door. This dynamic design separates the access function from the door opening action, preventing abnormal sounds during normal driving while maintaining convenient article retrieval.
2Volume of stationary object
If extendable shielding curtains are used in the luggage compartment, then space can be utilized, but the shielding curtains have low strength and cannot hold heavy articles
Solution Approach 1:
The shielding plate uses composite material construction combining rigid and flexible components. The main body is made of strong, rigid material capable of supporting heavy articles, while incorporating flexible sealing edges or connectors that allow for space optimization. This composite approach maintains high strength for article support while enabling efficient space utilization in the luggage compartment.
3Strength
If a fixed shielding plate is used in the luggage compartment, then articles can be held securely, but it is inconvenient to take or place articles without operating the shielding plate
Solution Approach 1:
The shielding plate is segmented into fixed and movable portions. The fixed portion maintains structural strength for secure article holding, while the movable portion can be independently operated to provide access. This segmentation allows users to access articles by opening only the movable section rather than operating the entire shielding plate or back door, improving convenience while maintaining security.
Solution Approach 2:
The movable section acts as an intermediary between the fixed shielding plate and the back door. It provides a intermediate access point that allows users to retrieve or place articles without fully opening the back door or disturbing the fixed shielding structure, thereby maintaining both security and operational convenience.
