Trailer Bolster Fender Bracket Single Fastener Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fender systems for trailer groups require the removal of multiple bolts for installation and removal, making the process cumbersome and time-consuming.
Innovation Solution
A bracket with upwardly extending retaining arms is secured to the bolster, allowing the fender to be retained by a single medial retaining means, enabling easier installation and removal by sliding the fender ends into gaps defined by the arms and using a post or aperture for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple bolts are used to attach the fender to the bolster, then the fender is securely retained, but the installation and removal process becomes cumbersome and time-consuming
Solution Approach 1:
The bracket is divided into two separate retaining arms (first and second retaining arms) that are spaced apart. Each arm independently retains one side of the fender, allowing the fender to be secured through two separate attachment points rather than requiring multiple bolts at each end. This segmentation enables faster installation while maintaining secure retention.
2Strength
If multiple bolts are used at each end of the fender, then the fender is securely attached, but the number of fastening points increases to four, making the process more complex
Solution Approach 1:
The invention extracts and eliminates the need for multiple bolts at each end of the fender. Instead of requiring four bolt attachment points (two at each end), the design uses a single bracket with two retaining arms that contact the fender at two separate locations. This extraction of unnecessary fastening points reduces complexity while maintaining adequate attachment strength through the distributed retention approach.

AI summary
An improved removable and installable fender for the bolsters of a trailer group relies on the use of a bracket on the bolster, the bracket having two retaining arms. A single fastening means is provided on the bolster to receive a bolt securing a medial portion of the end of the fender to the bolster, allowing the distal sides of the fender to be retained between the two retaining arms of the bracket and the body of the bolster.
