Solution Overview

Problem

Existing motorcycle fender accessory mounting systems lack a secure and versatile method for attaching various accessories, such as passenger seats and luggage racks, which can lead to vibration, noise, and damage to the fender's paint.

Innovation Solution

A bracket assembly with a locating portion and a mating portion, including protrusions and slots, is used in conjunction with a chrome-plated attachment member and mounting members on the fender, allowing for secure attachment and easy removal of accessories via fasteners, with rubber spacers for protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If accessories are mounted directly to the fender using conventional methods, then the mounting process is simple, but the attachment is insecure leading to vibration and noise

Engineering Contradiction:
Improveattachment securityVSAvoidmounting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional components: a bracket with locating portion and mating portion, an attachment member with receiving area, and fasteners. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket is received within the receiving area of the attachment member, creating a nested structure. The locating portion fits into the attachment member, and the mating portion engages with fasteners. This nested arrangement secures accessories firmly to the fender, eliminating vibration and noise while maintaining a compact mounting system.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If mounting systems are designed for secure attachment, then vibration and noise are reduced, but the fender paint may be damaged

Engineering Contradiction:
Improveattachment securityVSAvoidpaint damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The attachment member acts as an intermediary component between the bracket and the fender. It provides a receiving area that accommodates the bracket while distributing mounting stresses away from the fender's cosmetic paint surface. The attachment member can be permanently mounted to the fender through appropriate methods without damaging the paint, thereby protecting the fender appearance while maintaining secure accessory attachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If a permanent mounting system is used, then accessory stability is improved, but accessory removal and switching becomes difficult

Engineering Contradiction:
Improveaccessory stabilityVSAvoidaccessory removal ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The mounting system combines permanent and removable features dynamically. The attachment member is permanently mounted to the fender to provide a stable base, while the bracket and accessory can be easily attached and removed using fasteners. This dynamic design allows accessories to be securely mounted during use for stability, yet easily removed when accessory switching is desired, maintaining both stability and operational ease.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If a versatile mounting system is designed to accommodate various accessories, then adaptability is improved, but system complexity increases

Engineering Contradiction:
Improveaccessory compatibilityVSAvoidmounting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting system is designed with universal components that can accommodate various accessories. The bracket with its locating portion and mating portion can be configured for different accessory types, while the attachment member with its receiving area provides a standardized interface. This universal design allows the same basic mounting system to securely attach different accessories (passenger seats, luggage racks, etc.) without increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present device includes a removable system for an accessory assembly mounted to the fender of a motorcycle. The accessory is generally attached to a bracket that mates with an attachment member connected to the fender. Fasteners may be utilized to ensure that the bracket remains joined to the attachment member. Upon removal of the fasteners, the bracket may be separated from the attachment member. When the accessory is removed from the fender, the attachment member represents an aesthetically pleasing component of the fender. In addition, the attachment member also provides protection for the fender so that when the accessory is attached to the fender, the accessory does not damage the paint thereof.
