Motorcycle Gear Shift Peg Linkage for No-Foot-Movement Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear shift systems for vehicles, particularly motorcycles, require users to move their foot between different members to perform gear shifts, leading to reduced speed and safety, and are often poorly aligned due to varying gear shift bracket shapes and orientations, making it difficult to design a universal solution.
Innovation Solution
A device is connected directly to the gear shift peg member, allowing both first and second gear shifts without foot movement, with adjustable alignment and spacing, and a pivotable connection to accommodate different motorcycle configurations, enhancing alignment and ease of retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device is connected to the gear shift bracket, then the device can be installed on different motorcycles, but the alignment of the first and second members becomes poor due to varying bracket shapes and orientations
Solution Approach 1:
The device is divided into separate components: a bracket portion that attaches to the motorcycle's gear shift bracket, and a gear shift member portion with first and second members. This segmentation allows the bracket to adapt to different motorcycle configurations while the gear shift members maintain precise alignment through their connection to the gear shift peg member.
Solution Approach 2:
The gear shift peg member serves as an intermediary connection point between the device and the motorcycle's existing gear shift system. By connecting to this standardized component rather than directly to varying brackets, the device achieves both adaptability across different motorcycles and precise alignment of its members.
2Ease of operation
If the user moves their foot between different members to perform gear shifts, then the existing gear shift system can be used, but the gear shift speed decreases and safety is reduced
Solution Approach 1:
The device combines the functions of multiple gear shift operations into a single foot position. The first member and second member are positioned such that the user can perform both first gear shift and second gear shift operations without moving their foot, effectively merging multiple shift actions into one stationary position.
Solution Approach 2:
The device extends the gear shift members in a transverse direction perpendicular to the direction of travel, creating a new spatial dimension for foot placement. This allows the user to access both first and second members simultaneously from a single position, eliminating the need for longitudinal foot movement between shifts.
3Adaptability or versatility
If a device is designed to connect to gear shift brackets extending in forward or backward directions, then it can accommodate different configurations, but the device complexity increases
Solution Approach 1:
The bracket portion of the device incorporates pivotable or adjustable connections that can adapt to gear shift brackets extending in different directions. This dynamic capability allows a single device design to accommodate various motorcycle configurations without requiring multiple specialized designs.

AI summary
A device for a gear shift system for a vehicle, the gear shift system comprising a gear shift member, the device comprises a device member, and a member connector configured to connect to the gear shift member and thereby connect the device to the gear shift system so that, in use, one of the device member and the gear shift member is beneath a rider's foot to provide a first member, and the other of the device member and the gear shift member is above the rider's foot to provide a second member, wherein in use downwards movement of the first member effects a first gear shift and in use upwards movement of the second member effects a second gear shift.
