Bicycle Brake Disk Parking Lock for Slope Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders face inconvenience when parking bicycles on slopes, as the bicycle may slide down due to the inclination angle, requiring constant holding of the brake lever to prevent movement.
Innovation Solution
A bicycle braking and parking device that includes a casing, brake pads, a locking pin, and an electromagnetic driver, which allows the locking pin to move between a released and locked position to clamp the brake disk, or uses a driving piston to clamp the brake disk, ensuring the bicycle remains stationary even when the brake lever is released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brake lever is released to allow free operation, then the ease of operation is improved, but the bicycle cannot remain stationary on a slope
Solution Approach 1:
The parking brake mechanism performs preliminary action by automatically engaging the brake pads with the brake disk when the brake lever is released, creating a pre-set braking force that holds the bicycle stationary on slopes without requiring continuous rider input
Solution Approach 2:
The system provides self-service functionality where the release of the brake lever automatically triggers the parking brake mechanism to engage, and subsequent release of the parking brake requires deliberate rider action through the dedicated release lever, making the system self-regulating
2Reliability
If the brake lever is continuously held to prevent sliding on a slope, then the stationary holding capability is improved, but the rider cannot leave the bicycle for other activities
Solution Approach 1:
The parking brake mechanism is pre-configured to automatically engage when the brake lever is released, providing immediate stationary holding capability that allows the rider to leave the bicycle without continuously holding the brake lever
Solution Approach 2:
The system automatically maintains the braking function through the parking brake mechanism, freeing the rider from continuous manual intervention while the bicycle remains stationary on a slope
3Reliability
If a locking pin mechanism is added to prevent movement on slopes, then the stationary holding capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the braking and parking functions into a single integrated mechanism where the brake pads, pistons, and locking pin work together as a unified system, reducing overall complexity despite adding parking capability
Solution Approach 2:
The brake pads serve dual functions: they act as friction elements for dynamic braking during riding and as locking elements for stationary parking, eliminating the need for separate braking and parking mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively prevents unwanted movement of the bicycle on a slope, allowing riders to safely leave the bicycle unattended without holding the brake lever.
Implementation Method 1
The electromagnetic driver is configured to force the locking pin to move between a released position and a locked position
Implementation Method 2
The pistons are configured to push the brake pads, and the brake pads are configured to clamp the brake disk
Implementation Method 3
The driving piston is configured to cause oil in the third chamber, the second inlet channel, and the second chambers to trigger the second pistons to push the second brake pads to clamp the brake disk

AI summary
A bicycle braking and parking device includes a casing, two brake pads, a locking pin, and an electromagnetic driver. The casing has an accommodation space and two pistons located at two opposite sides of the accommodation space. The accommodation space can accommodate part of a brake disk. The brake pads are located at the accommodation space and located between the pistons. The pistons can push the brake pads, and the brake pads can clamp the brake disk. The locking pin is movably disposed on the casing. The electromagnetic driver can force the locking pin to move between a released position and a locked position. when the locking pin is in the released position, the locking pin is separated from the brake disk. When the locking pin is in the locked position, the locking pin is inserted into the brake disk to limit a motion of the brake disk.
