Pickup Truck Tie-Down Anchor Structure to Prevent Buckle Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no hook in pickup trucks to connect ropes for securing goods, leading to instability and inconvenience in tying items to the carriage.
Innovation Solution
A pickup truck fastening anchor comprising a fixed part with an iron bracket and aluminum block, and a stretching part with an aluminum U-ring, secured with hexagonal screws and springs to prevent detachment, allowing the rope to be securely fastened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional buckle is used to connect the rope in the pickup truck carriage, then the connection can be established, but the buckle can easily fall off and the connection is unstable
Solution Approach 1:
The device is divided into a fixed part (iron bracket attached to aluminum block) and a stretching part (aluminum U-ring with buckles). This segmentation allows the fixed part to provide stable anchoring while the stretching part provides flexible rope connection, resolving the contradiction between stability and simplicity.
Solution Approach 2:
The iron bracket and aluminum block are combined into a unified fixed part that integrates anchoring and positioning functions. This merging creates a more reliable connection system compared to a simple buckle alone, while maintaining reasonable structural complexity.
2Reliability
If the buckle connection is used without additional fastening mechanisms, then the installation is simple, but the device can detach and fall during vehicle operation
Solution Approach 1:
The iron bracket is pre-attached to the aluminum block before use, creating a pre-assembled fixed part. This preliminary action ensures that the anchoring structure is already stabilized when installed in the carriage, preventing detachment during vehicle operation while keeping the overall installation process simple.
Solution Approach 2:
The aluminum U-ring provides dynamic flexibility in the stretching part, allowing the rope to be easily threaded and adjusted. This dynamic design maintains ease of operation while the fixed part ensures anti-detachment reliability through its rigid construction.
3Object-affected harmful factors
If a simple buckle is used for rope connection, then the device is easy to install, but it generates noise during vehicle operation
Solution Approach 1:
The device uses composite construction with both iron (bracket) and aluminum (block and U-ring) materials. This composite approach provides noise reduction through material damping properties while maintaining manufacturing simplicity through standard metal fabrication processes.
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 device provides a stable and convenient means to secure goods by preventing the buckle from falling and reducing noise during vehicle operation, ensuring the rope remains bound to the carriage.
Implementation Method 1
a thick spring is set in the through hole of the aluminum block; the front ends of the hexagonal screws abut against the thick spring, the thick spring is sleeved outside the aluminum U-ring; and the two ends of the thick spring are respectively abutted against the nuts and the iron bracket
Implementation Method 2
the front end of the hexagonal screw is sleeved with a thin spring, the front end of the thin spring is abutted against a rolling ball
