Motorcycle Wheel Balance Device With Threaded Pedestal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel balance devices for motorcycles lack an efficient and secure method to attach and balance the wheel, making tire and tube replacement difficult.
Innovation Solution
A cylindrical pedestal with a concave end and longitudinal channel is attached to the inner rim, allowing an arched weight body with a hole to be inserted through an orifice, secured by a threaded fastener, which aligns with the channel to provide balance and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing wheel balance devices are used, then wheel balancing function is provided, but attachment security and ease of operation deteriorate due to lack of efficient attachment method
Solution Approach 1:
The balance device is divided into separate components: a pedestal that attaches to the rim, a weight body that can be adjusted, and a threaded fastener that secures them together. This segmentation allows for easy attachment and adjustment while maintaining secure fastening through the threaded connection mechanism.
Solution Approach 2:
The threaded fastener acts as an intermediary element that bridges the pedestal and weight body, providing both ease of attachment through threading and reliable security through the engaged fastener. The fastener mediates between the need for simple installation and the requirement for secure attachment.
2Ease of repair
If existing wheel balance devices are used, then wheel balancing is achieved, but tire and tube replacement becomes difficult due to insecure fastening
Solution Approach 1:
The balance device incorporates a threaded fastener system that allows for dynamic adjustment and easy removal. The threaded connection enables the device to be securely attached during operation but easily detached when tire replacement is needed, providing both reliability during use and ease of repair when required.
Solution Approach 2:
The balance device is designed with pre-threaded holes and fasteners that allow for preliminary secure attachment before riding, but enable quick removal when tire replacement becomes necessary. The threaded fastening system is prepared in advance to provide both secure fastening and easy detachment.
3Reliability
If a secure attachment method is implemented, then attachment reliability improves, but device complexity increases
Solution Approach 1:
The threaded fastener combines multiple functions into a single element: it secures the weight body to the pedestal, allows for adjustable positioning, and provides easy attachment and removal. This merging of functions achieves reliable attachment without significantly increasing device complexity, as the threaded fastener is a simple, common component.

AI summary
A wheel balance device for a motorcycle attachable to a motorcycle wheel rim. The wheel balance device includes a pedestal vertically attachable to a crown of an inner rim of the motorcycle wheel rim in a position between a pair of spokes on opposite side of the crown and having a first end attachable to the crown, a second end, an outer wall therebetween, a transverse orifice therethrough, and a longitudinal channel continuously disposed therethrough. A weight body, having an arc substantially conforming to a shape of the inner rim, is insertable through the transverse orifice and has a hole transversely disposed therethrough, which is alignable with the channel when the weight body is inserted into the transverse orifice. A fastener, which engages both the channel pedestal and the hole of the weight body, secures the weight body to the pedestal.
