Lean Vehicle Stand and Driving Preventing Device Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders of lean vehicles, such as motorcycles, face inconvenience as they need to separately release the parking brake and flip up the stand to start driving after the vehicle has stopped, which can lead to confusion and increased operational complexity.
Innovation Solution
A lean vehicle is equipped with a driving preventing device that includes a stand capable of switching between a landed state for self-support and a flip-up state, and an operation piece that allows the driver to select between driving enabled and disabled states, ensuring the parking brake is released when the stand is flipped up, thus simplifying the starting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rider releases the parking brake and flips up the stand separately to start driving, then the vehicle can be properly prepared for driving, but the operational complexity increases and the starting process becomes less smooth
Solution Approach 1:
The patent combines the parking brake release operation and the stand flip-up operation into a single integrated mechanism. When the stand is flipped up, it automatically triggers the release of the parking brake through a connected linkage system, eliminating the need for separate operations and reducing starting complexity while ensuring both actions are properly executed
Solution Approach 2:
The system performs the parking brake release action in advance as part of the stand flip-up sequence. By designing the linkage so that brake release is automatically triggered when the stand begins to flip up, the system prepares the vehicle for driving before the rider completes the starting motion, improving both reliability and ease of operation
2Adaptability or versatility
If the operation piece allows free movement between driving enabled and disabled positions, then the rider has flexibility in selecting driving states, but the risk of accidental brake engagement increases
Solution Approach 1:
The stand acts as an intermediary mechanism between the rider's intent and the parking brake state. The mechanical linkage ensures that the operation piece can only change the parking brake state when the stand is in the appropriate position, providing a physical mediator that prevents accidental engagement while preserving rider flexibility when the stand position is correct
Solution Approach 2:
The system dynamically links the operability of the parking brake control to the stand position. The operation piece's ability to change states is conditioned on the stand being in the correct position, creating a dynamic constraint that adapts based on vehicle configuration rather than a fixed mechanical lock

AI summary
A lean vehicle (1) includes: a driving preventing device configured to switch between a driving enabled state in which normal driving of the vehicle (1) is being enabled and a driving disabled state in which the normal driving of the vehicle (1) is being disabled; and a stand configured to swing between a landed state and a flip-up state and, in the landed state, make the vehicle (1) stand by itself while the vehicle (1) is in a stop state. When the stand is in the landed state, the driving preventing device is allowed to switch between the driving enabled state and the driving disabled state. When the stand is in the flip-up state, the driving preventing device is maintained in the driving enabled state.
