Motorcycle Case Handle Actuation Mechanism for Lid Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking and fastening devices for motorcycle storage cases require users to release the storage case from the motorcycle chassis to open the lid, posing safety risks and increasing the complexity and cost due to numerous components.
Innovation Solution
A handle actuation mechanism that allows the storage case to remain attached to the chassis in an extended intermediate position, enabling lid opening and closing without uncoupling, featuring a connecting rod system and a cylinder lock for secure operation, reducing the number of components and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage case is uncoupled from the motorcycle chassis to open the lid, then the lid can be opened, but the storage case becomes vulnerable to theft and user safety is compromised
Solution Approach 1:
The handle actuation mechanism is divided into two independent functions: a first handle for lid opening and a second handle for storage case uncoupling. This segmentation allows the lid to be opened while the storage case remains securely attached to the motorcycle chassis, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The locking element serves multiple functions: it locks both handles in their retracted positions simultaneously, preventing accidental uncoupling while allowing intentional lid opening. This multi-functionality enables the system to maintain security while providing operational flexibility.
2Ease of operation
If two separate handles are used for lid opening and storage case uncoupling, then both functions can be performed, but the device complexity and component count increase
Solution Approach 1:
The locking element is integrated into the actuation mechanism of both handles, combining the locking function with the existing handle structures. This merging approach enables dual-handle functionality without adding separate locking mechanisms, thereby reducing overall device complexity while maintaining functional capability.
3Ease of operation
If the handle is positioned to open the lid, then the lid can be accessed, but the storage case becomes uncoupled from the motorcycle chassis
Solution Approach 1:
The handles are designed with independent actuation paths: the first handle can be rotated to the active position for lid opening without requiring the second handle to be actuated. This dynamic independence ensures that lid access can be achieved while the storage case remains firmly coupled to the motorcycle chassis through the unactuated second handle.

AI summary
Locking and fastening device for a motorcycle case, comprising a mechanism for opening and closing the lid of the storage case, a handle articulated in such a way that it can be rotated from a retracted position to an extended final position for transporting the storage case, said handle being operationally connected to at least one fastening element arranged to fasten the storage case to the motorcycle chassis in a removable manner when the handle is in a retracted position, the storage case susceptible to being released from the motorcycle when the handle is actuated to the extended final position for transporting, said device comprising means for locking the opening and closing lid mechanism by means of the handle when said handle is in the retracted position, characterised in that it comprises a handle actuation mechanism configured to provide an extended intermediate position of the handle capable of releasing the actuation of the opening and closing lid mechanism while the storage case remains attached to the motorcycle chassis.
