Motorcycle Tandem Grip Unit Integrating Luggage Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motorcycle designs with pannier bags and top cases often complicate the rear frame structure, leading to increased complexity and a higher number of components, which can affect the stability and aesthetics of the vehicle.
Innovation Solution
A tandem grip unit with integrally formed elements, including a to-be-supported portion, grip portion, bag fitting portion, and casing fitting portion, which reduces the number of components and increases rigidity, allowing for stable support of pannier bags and top cases without complicating the rear frame structure, and includes a rope hook and elongated casing stay for improved luggage support and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pannier bags and top casing are supported by the rear frame structure, then the luggage storage function is achieved, but the rear frame structure becomes complicated
Solution Approach 1:
The patent merges the support function for pannier bags and top casing into the existing rear frame structure by providing dedicated support protrusions and recesses. The support protrusions on the rear frame structure engage with corresponding recesses in the pannier bags and top casing, integrating the luggage storage function into the frame without requiring separate complex support mechanisms.
Solution Approach 2:
The rear frame structure is designed with multi-functionality by incorporating support protrusions that can accommodate both pannier bags and top casing. This universal support system allows the same frame structure to provide luggage storage for different types of bags, eliminating the need for separate dedicated support structures for each bag type.
2Adaptability or versatility
If multiple separate components are used for supporting pannier bags and top casing, then the support function is achieved, but the number of component parts increases
Solution Approach 1:
The patent combines multiple support functions into integrated support protrusions and recesses within the rear frame structure. Instead of using separate support brackets, mounts, and fasteners for each bag type, the design incorporates all necessary support features directly into the frame structure, reducing the total number of component parts.
Solution Approach 2:
The rear frame structure provides self-service support by including built-in support protrusions that directly engage with the pannier bags and top casing. This self-contained support system eliminates the need for additional separate support components, as the frame structure itself performs the support function through its integrated features.
3Stability of the object's composition
If the rear frame structure is made more complex to support pannier bags and top casing, then the support stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the support features into the existing rear frame structure by providing support protrusions and corresponding recesses that are formed as integral parts of the frame. This integration provides stable support for pannier bags and top casing while avoiding the need for complex separate support mechanisms that would increase manufacturing complexity.
Solution Approach 2:
The support function is segmented into discrete support protrusions and recesses within the rear frame structure. This segmentation allows for simplified manufacturing by breaking down the support function into manageable geometric features that can be formed through standard manufacturing processes, rather than requiring complex monolithic structures.

AI summary
A tandem grip unit (24) includes a pair of left and right tandem grips (22). Each of the tandem grips (22) in turn includes a to-be-supported portion (32) supported by a vehicle frame structure (FR), a grip portion (34) to be grasped by a fellow passenger, a bag fitting portion (36) to which a pannier bag (26) is fitted, and a casing fitting portion (38) to which a top casing (28) is fitted, all of those elements being formed integrally.
