Motorcycle Lateral Case Vertical Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lateral cases for motorcycles require inconvenient horizontal or oblique movements for coupling and release, making operations cumbersome, especially with heavy loads, and lack simple and reliable locking/unlocking solutions, often requiring a metal support frame.
Innovation Solution
A coupling device that allows vertical movement for coupling and release, featuring hooks and sliders that engage with the motorcycle frame, eliminating the need for a support frame and providing a single, intuitive, and secure locking mechanism using a single lock and lever system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If horizontal or oblique translation movement is used for coupling and release, then the coupling can be achieved, but the operation becomes inconvenient and complicated especially when the bag is heavy
Solution Approach 1:
The patent changes the movement direction from horizontal/oblique to vertical by reorienting the coupling mechanism. The bag is coupled by moving it vertically onto the support frame, which eliminates the need for awkward horizontal translations especially when the bag is heavy with luggage
2Reliability
If multiple coupling and locking mechanisms are used, then the security and reliability are improved, but the device complexity increases
Solution Approach 1:
The patent merges the coupling and locking functions into a single integrated mechanism. The coupling device includes both coupling elements and locking elements that work together in one unified system, reducing the number of separate components while maintaining security and reliability
Solution Approach 2:
The support frame serves multiple functions: it provides structural support, enables coupling through vertical movement, and incorporates locking mechanisms. This multi-functional design reduces overall system complexity while maintaining reliability
3Adaptability or versatility
If a metal support frame is installed on the motorcycle, then the coupling and support function is achieved, but the aesthetic integrity of the motorcycle is compromised
Solution Approach 1:
The support frame is designed with localized features rather than a complete metal framework. The frame includes specific coupling and locking elements positioned only where needed for bag attachment, minimizing visual impact while maintaining structural function and aesthetic integrity

AI summary
A lateral case for motorcycles provided with an improved coupling/release device for the coupling and release of the case itself to/from the vehicle frame is configured to allow the user to perform the coupling and release operations with a single and simple vertical movement of the bag with respect to the motorcycle frame, so that the coupling/release operation is simpler and more convenient for the user.Furthermore, the coupling/release device of the lateral case is easy for the user to activate and has a high degree of security towards accidental or fraudulent openings.
