Bicycle Steering Lock via Adjustable Clamp and Rotatable Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles, especially touring bikes loaded with equipment, are inherently unstable when parked, prone to rolling or falling due to the front wheel turning, which poses challenges in both parking and handling during use.
Innovation Solution
A device comprising a clamp, lever, and receiver that securely couples with the steer tube and other bicycle components, preventing the front wheel from turning by using adjustable clamps, rotatable levers, and high-friction materials to lock the wheel in place, ensuring stability when parked or being handled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bicycle is parked without any stabilization device, then the device complexity is minimal, but the bicycle becomes unstable and prone to rolling or falling over
Solution Approach 1:
The stabilization device is divided into separate functional components: a clamp that attaches to the steer tube, a lever that provides rotational control, and a receiver that anchors to the bicycle frame. This segmentation allows each component to perform its specific function while maintaining overall simplicity and effectiveness in preventing bicycle rolling or falling.
Solution Approach 2:
The clamp acts as an intermediary element between the bicycle's steer tube and the lever mechanism. It provides a secure attachment point that translates the lever's rotational motion into effective stabilization force, mediating between the simple anchor points and the complex stabilization function required to prevent rolling.
2Stability of the object's composition
If a stabilization device is added to prevent wheel turning, then the bicycle stability improves, but the ease of operation deteriorates due to the need to manually adjust and secure the device
Solution Approach 1:
The lever is designed to be rotatable through a range of motion from vertical through horizontal to the proper angle, allowing dynamic adjustment during operation. This rotational capability enables the user to easily position the lever for secure engagement with the receiver while maintaining ease of operation despite the added stabilization function.
Solution Approach 2:
The clamp is designed to be adjustable to fit many sizes of bikes by changing its dimensional parameters. This adjustability allows the same device to be easily operated on different bicycle sizes without requiring complex reconfiguration, maintaining ease of operation while providing universal stabilization functionality.
3Adaptability or versatility
If the clamp is made adjustable to fit many bicycle sizes, then the adaptability improves, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The clamp is designed with universal adaptability to fit many bicycle sizes through simple adjustment mechanisms. This multi-functionality allows a single device design to serve multiple bicycle types and sizes, achieving high adaptability without requiring complex size-specific variants or overly complicated adjustment systems.

AI summary
A device for preventing the front wheel of a bicycle from turning, comprising a clamp, a lever, and a receiver. The clamp is configured to be removably coupled with the steer tube of a bicycle, and is adjustable. The adjustable clamp is configured to be secured tightly around the steer tube to prevent rotation of the front wheel of the bicycle and to prevent rotation of the clamp around the steer tube. The lever is coupled with the clamp and is rotatable from vertical, through horizontal, to the proper angle to meet the receiver, which is disposed on a cross bar or down tube of a bicycle. The lever includes a knob and the receiver is configured to receive and slightly contract around the knob, temporarily coupling the steer tube and the cross bar or down tube, locking the wheel in its position when the lever is engaged.
