Motorcycle Case Pivoting Extension Volume Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle cases have a fixed inner volume, limiting user flexibility and increasing manufacturing costs due to the need for custom locks in expandable designs.
Innovation Solution
A motorcycle case with a pivoting extension that adjusts between two positions, allowing for increased inner volume while using the same lock as fixed volume cases, featuring a latch system for easy volume adjustment and intermediate positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a flexible or telescopic part is added to enable extension of the base or lid, then the inner volume can be increased, but the lock must be different for these cases, increasing manufacturing cost
Solution Approach 1:
The extension is designed to pivot about a longitudinal axis of the lock, allowing dynamic adjustment of the inner volume between first and second positions. This dynamic mechanism enables the same lock to function with varying volumes, eliminating the need for custom locks for each volume configuration and thereby reducing manufacturing costs while maintaining expandability.
2Volume of moving object
If a flexible or telescopic part is added to enable extension of the base or lid, then the inner volume can be increased, but the design becomes more complex
Solution Approach 1:
The extension pivots about a longitudinal axis of the lock, creating a dynamic structure that adjusts volume while maintaining a relatively simple design. The lid is fixed to the extension in the pivoting movement, and the extension can be mounted on the base in a slidable way, providing volume adjustment without requiring complex mechanical systems.
Solution Approach 2:
The case is divided into a base, a lid, and an extension that can be independently positioned. The extension can be in different positions (first position for smaller volume, second position for larger volume), allowing the case to be segmented into functional parts that can be reconfigured without increasing overall design complexity.
3Ease of operation
If the extension is fixed to the lid in the pivoting movement, then the lid moves with the extension, but the structure becomes more complex
Solution Approach 1:
The extension is designed to pivot about a longitudinal axis of the lock, allowing dynamic adjustment of the inner volume between first and second positions. The lid is fixed to the extension in the pivoting movement, and the extension can be mounted on the base in a slidable way, providing volume adjustment without requiring complex mechanical systems.

AI summary
The invention relates to a case for motorcycles which comprises a base (1) and a lid (2) that define an inner housing (3), the case also comprising a lock (4) for locking the lid (2) and the base (1) together, preventing access to the inner housing (3), and it is characterized in that the case further comprises an extension (5) that pivots about the longitudinal axis (X) of said lock (4), between at least a first and a second position, said second position defining a volume of the inner housing (3) greater than the volume of the inner housing (3) when the extension (5) is in said first position. It allows the design of the case to be more flexible and aerodynamic than conventional expandable cases.
