Motorcycle Passenger Armrest with Rotating Accessory Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles lack a convenient location for passengers to store accessories like cell phones or beverages, and there is no provision for an armrest, which would enhance comfort and utility.
Innovation Solution
A passenger armrest with a built-in mount that can be attached to the motorcycle structure, featuring a keyed cavity system allowing accessories to be securely held and rotated to maintain level positioning, with optional features for locking or restricting rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a passenger backrest is mounted to the trunk lid, then passenger support is provided, but no armrest or accessory storage is available
Solution Approach 1:
The patent combines the armrest and accessory mount into a single integrated assembly that attaches to the motorcycle trunk lid near the passenger backrest. This merging of functions provides both armrest support and accessory storage in one component, resolving the contradiction between comfort and versatility.
Solution Approach 2:
The armrest assembly serves multiple functions: it provides armrest support for passenger comfort, includes a cavity for storing accessories like beverages or electronics, and features a rotatable mount that can hold various accessories. This multi-functionality addresses both comfort and adaptability needs simultaneously.
2Adaptability or versatility
If accessories are mounted on the passenger area, then storage capability is improved, but stability during motorcycle movement may be compromised
Solution Approach 1:
The accessory mount is designed to rotate about an axis, allowing it to dynamically adjust and maintain a level position during motorcycle movement. This rotational capability enables the accessory to remain stable and level despite vehicle motion, resolving the contradiction between storage capability and stability.
Solution Approach 2:
The mount's rotational parameter allows the accessory to change its orientation dynamically. By rotating the mount about a horizontal axis, the accessory can maintain a level position relative to gravity rather than the motorcycle's frame, ensuring stability during acceleration, deceleration, or cornering.
3Ease of operation
If a rotatable mount is provided for accessories, then level positioning is maintained, but device complexity increases
Solution Approach 1:
The mount mechanism is segmented into simple components: a rotational joint allowing movement about a horizontal axis and a locking mechanism. This segmentation keeps the complexity low while providing the necessary level positioning capability through straightforward mechanical means rather than complex systems.
