Solution Overview
Problem
Existing spacers for fastening motorcycle side bags are not stable, safe, and require complex and time-consuming application and removal processes.
Innovation Solution
A spacer system with a spacer rod and fastening plate featuring a locking mechanism with an anchoring pin and control lever, allowing easy and secure attachment and detachment to the motorcycle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple spacer rod is used without locking mechanism, then the application and removal process is quick, but the spacer is not stable and safe in use
Solution Approach 1:
The control lever dynamically switches the retention means between retracted (release) and advanced (locked) positions, allowing the spacer to transition between easily removable and securely locked states. This dynamic mechanism resolves the contradiction by providing both quick operation and stable fixation at different stages of use.
Solution Approach 2:
The retention means acts as an intermediary element between the spacer rod and fastening plate, providing a mechanical locking action that ensures stability during use while allowing controlled release. This intermediary component enables both secure fastening and easy removal without requiring complex procedures.
2Reliability
If a locking mechanism is added to ensure stability, then the spacer becomes safe in use, but the application and removal process becomes complex and time-consuming
Solution Approach 1:
The control lever and retention means are merged into a single integrated control system. Operating one control lever simultaneously manages the retention means position, providing a unified and simple operation that avoids complex multi-step locking procedures while ensuring stable fastening.
Solution Approach 2:
The dynamic positioning of the retention means (retracted or advanced) controlled by a single lever provides reliable locking without complex mechanisms. The system transitions smoothly between states, maintaining simplicity in structure and operation while ensuring stability during use.
3Reliability
If a locking mechanism with retention means is used, then the spacer provides secure fastening, but the application and removal process takes more time
Solution Approach 1:
The retention means is pre-positioned in the retracted state, allowing the spacer rod to be quickly inserted into the fastening plate before locking. This preliminary configuration enables rapid application, and the single lever operation provides quick locking and release, minimizing the time required for secure fastening and removal.
Solution Approach 2:
The dynamic control mechanism allows rapid transition between locked and released states through a single lever operation. This minimizes the time required for both application and removal while ensuring secure fastening when locked, resolving the time-consuming issue without compromising reliability.

AI summary
A spacer for fastening a side bag (2) to a side of a motorcycle comprises a spacer rod (10) and a fastening plate (12) suitable to be anchored to a side of the motorcycle frame to fasten the spacer rod (10) to the motorcycle in a removable manner. The spacer rod is provided with an anchoring pin (14) which fits into a pin seat (16) of the fastening plate (12). This is provided with a pin locking mechanism (18) operatively connected to the pin seat and comprising retention means (20) radially movable with respect to a pin axis (X) between a retracted pin releasing position and an advanced pin locking position.
