Vehicle Load Deck Attachment Device With Adjustable Tail Lamp Guards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attachment devices for vehicles with load carrying decks require replacement when changing the retaining portion's specification, and deck extension members can obstruct load mounting due to fixed storage positions.
Innovation Solution
A multi-purpose vehicle design with adjustable tail lamp guards and rear bumpers that act as support members, and an attachment device with a sliding adjustable mounting portion on the gate's upper edge for customizable retaining portions, along with a deck extension member that can be pivoted and adjusted in the front-rear direction for non-obstructive storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire attachment device is replaced to change the retaining portion's specification, then the retaining portion can be changed to a different specification, but the cost increases
Solution Approach 1:
The attachment device is divided into two independent parts: the mounting portion (which remains fixed) and the retaining device (which can be replaced). This segmentation allows users to change only the retaining device to modify the retaining portion's specification, rather than replacing the entire attachment device, thereby reducing cost while maintaining adaptability.
Solution Approach 2:
The mounting portion is designed with universal compatibility to work with different types of retaining devices. The mounting portion includes a mounting hole that can accommodate various retaining devices (such as hooks, eyes, or other fastening mechanisms), allowing one mounting portion to serve multiple functions with different retaining specifications.
2Device complexity
If the deck extension member is stored in a fixed position, then the storage structure is simple, but it obstructs load mounting
Solution Approach 1:
The deck extension member is designed to be movable rather than fixed in storage. It can be pivoted between a stored position (along the vehicle side) and an extended position (protruding rearward). This dynamic positioning allows the member to be moved out of the way during load mounting operations, eliminating obstruction while maintaining a relatively simple storage structure.
Solution Approach 2:
The deck extension member is positioned in a different spatial dimension during storage - it is stored along the lateral side of the vehicle body rather than protruding rearward. This dimensional repositioning removes it from the load mounting area, preventing obstruction while keeping the storage structure simple.
3Volume of moving object
If the deck extension member protrudes upwardly of the tailgate, then the deck space is extended, but it cannot be retracted for normal operations
Solution Approach 1:
The deck extension member is designed with pivotal movement capability, allowing it to switch between two states: extended upwardly of the tailgate to increase deck space, and retracted along the vehicle side for normal operations. This dynamic design provides adaptability in deck configuration while maintaining both extended and normal states.
Solution Approach 2:
The deck extension member provides localized space extension only when needed - it protrudes upwardly of the tailgate specifically at the rear deck area to increase cargo volume, while the rest of the deck maintains its normal configuration. This localized modification allows deck space extension without permanently altering the entire deck structure.
