Motorcycle Top Case With Independent Pivoting Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top cases for vehicles, such as motorcycles, have limited storage volume and inflexible handling, as they lack the ability to expand storage capacity efficiently while maintaining compactness.
Innovation Solution
A top case design featuring a lower shell and an upper shell that can pivot independently, with the outer shell capable of opening separately to provide additional storage space, increasing the overall storage volume without compromising compact handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the top case uses a single lid design, then the structure is simple and compact, but the storage volume is limited and handling flexibility is poor
Solution Approach 1:
The top case lid is segmented into two independent shells: an inner shell and an outer shell. The inner shell can be opened independently to access frequently used items, while the outer shell provides additional storage when fully opened. This segmentation allows flexible handling scenarios - users can open only the inner shell for quick access or both shells for maximum storage, thereby improving adaptability without requiring a completely complex new structure.
2Adaptability or versatility
If the top case uses a double lid design with independent pivotability, then storage volume and handling flexibility are improved, but the structure becomes more complex
Solution Approach 1:
The inner shell is nested within the outer shell, with the inner shell's cavity positioned inside the outer shell's cavity. Both shells share a common pivot axis and can rotate independently around this axis. This nesting arrangement maximizes storage volume by creating layered storage spaces while maintaining a compact overall structure when closed. The independent pivot capability of each shell provides flexible access options without requiring separate mounting mechanisms, thus managing structural complexity.
3Volume of stationary object
If the outer shell is made pivotable independently of the inner shell, then additional storage space is accessible, but the mechanism complexity increases
Solution Approach 1:
Both the inner shell and outer shell are connected to the top case body via pivot mechanisms that share a common pivot axis. This merging of pivot axes allows both shells to rotate independently around the same axis, providing flexible access to different storage compartments. The shared pivot mechanism reduces overall mechanism complexity compared to having separate pivot points, while still enabling the outer shell to be opened independently to access additional storage space.

AI summary
The invention relates to a top case for a vehicle, in particular for a motorcycle or a motorcycle-like vehicle, comprising a bottom shell and a top shell, which is arranged in such a way that the top shell can be pivoted in relation to the bottom shell in order to open the top case. In a closed position the bottom shell and the top shell define a common interior for storing objects. The upper shell comprises an inner shell and an outer shell that surrounds the inner shell and the outer shell can be pivoted into a first open position independently of the inner shell. The invention further relates to a vehicle having a corresponding top case.
