Swingarm Cover Bracket Mounting for Impact-Resistant Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swingarm covers on motorbikes are prone to failure when impacting obstacles due to insecure mounting methods, such as cable lashing, leaving the swingarm unprotected.
Innovation Solution
A bracket system is integrated with the swingarm cover that secures it to the swingarm using a bracket and fasteners, with the bracket being clamped by the axle adjustment bolt, allowing it to resist forces in multiple directions, and optionally incorporating vibration dampening and cushioning materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable lashing is used to secure the swingarm cover, then the mounting method is simple, but the reliability of the mounting is poor and prone to failure when impacting obstacles
Solution Approach 1:
The mounting system is divided into separate functional components: a bracket that attaches to the swingarm, a cover that protects the swingarm, and fasteners that secure them together. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability.
Solution Approach 2:
The bracket is pre-positioned and secured to the swingarm using the axle adjustment bolt before the cover is attached. This preliminary action ensures that the mounting structure is firmly established and ready to withstand impact forces before the protective cover is added.
2Reliability
If a secure mounting method with bracket and fasteners is used, then the reliability of the mounting is improved, but the device complexity increases
Solution Approach 1:
The bracket serves multiple functions: it provides a mounting structure for the cover, acts as a reinforcement for the swingarm, and works with the axle adjustment bolt to create a secure attachment point. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The system utilizes existing swingarm components (the axle adjustment bolt and its hole) to serve the dual purpose of adjusting chain tension and securing the mounting bracket. This self-service approach eliminates the need for separate fastening hardware and reduces overall system complexity.
3Strength
If the swingarm cover is securely mounted to resist impact forces, then the protection effectiveness is improved, but the mounting structure becomes more complex
Solution Approach 1:
The mounting system combines different materials and structural elements: the bracket (likely metal for strength), the cover (possibly plastic or composite for protection), and the fasteners. This composite approach allows each material to contribute its optimal properties for impact resistance while maintaining a relatively simple overall structure.

AI summary
A motorbike swingarm cover incudes a protective cover that covers at least a portion of the outer face of the motorbike swingarm. Said cover is secured to the motorbike swingarm through a cable lashing in the frontward portion of the cover, and a bracketed attachment in the rearward portion of the cover. Said bracketed attachment will secure onto both the cover and onto the motorbike swingarm by way of an included mounting feature on the swingarm.
