Motorcycle Transmission Locking Device for Anti-Rollaway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorcycle transmission systems lack a simple and effective mechanism for securing the vehicle against theft and undesired rolling away, as existing solutions are either complex to operate or provide inadequate protection.
Innovation Solution
A transmission system with a locking device and an operating element that can be manually actuated externally, combined with a securing device that can be wirelessly switched using a remote control, ensuring the locking element can be easily moved between locked and released positions, providing enhanced security and operation simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is added to secure the motorcycle against theft, then security against undesired rolling away is improved, but the device complexity increases
Solution Approach 1:
The locking element is designed to perform multiple functions: it locks the shaft against rotation to prevent theft, and simultaneously serves as the securing mechanism for the operating element. This multi-functionality reduces the need for separate securing mechanisms, thereby improving security without proportionally increasing device complexity.
Solution Approach 2:
The operating element is integrated within the locking device structure, with the securing device nested within the locking element. This nested arrangement allows multiple functional components to occupy the same space, reducing overall device complexity while maintaining comprehensive security functionality.
2Ease of operation
If a securing device with wireless remote control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The mechanical key-operated securing mechanism is replaced with a wireless remote control system using radio frequency communication. This substitution eliminates the need for physical key insertion and mechanical tumblers, significantly improving ease of operation. The wireless control unit and receiver are integrated into the existing locking device structure, minimizing the increase in overall device complexity.
3Ease of operation
If the operating element is accessible from outside the housing, then ease of operation is improved, but security against unauthorized access worsens
Solution Approach 1:
The locking element acts as an intermediary between the externally accessible operating element and the internal shaft. Even though the operating element is accessible from outside the housing for ease of operation, the locking element mediates by blocking the transmission path from the operating element to the shaft when in the locked position, thereby preventing unauthorized access while maintaining operational accessibility.

AI summary
A transmission for a motorcycle includes a housing, at least one shaft at least partially accommodated in the housing and which can be rotated relative to the housing, and a locking device having at least one locking element located in the housing. The at least one locking element is movable moved relative to the housing between at least one locking position in which the at least one locking element secures the shaft against rotation relative to the housing, and at least one release position in which the at least one locking element releases the shaft for rotation relative to the housing.
