Dual Brake Lever Assembly With Single Return Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-wheeler braking systems require multiple levers and springs for simultaneous actuation of front and rear brakes, leading to complex assemblies, increased space requirements, and potential for premature wheel skidding due to excessive braking force, especially on slippery roads.
Innovation Solution
A compact braking system with a single elastic member connecting two brake levers, allowing independent actuation and providing a return force, which reduces the need for additional delay mechanisms and minimizes the number of parts, thereby enhancing safety and reducing the risk of premature skidding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple levers and springs are used for simultaneous actuation of front and rear brakes, then braking functionality is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple brake levers and springs into a single integrated lever assembly. The single lever incorporates multiple actuation points that can independently engage with brake cables, eliminating the need for separate levers and multiple springs while maintaining the ability to actuate both front and rear brakes simultaneously or independently.
Solution Approach 2:
The single lever assembly is designed to perform multiple functions: it can independently actuate the front brake, independently actuate the rear brake, or simultaneously actuate both brakes. This multi-functional design replaces what would traditionally require multiple dedicated levers and spring mechanisms.
2Ease of operation
If multiple levers and springs are used for simultaneous actuation, then braking functionality is achieved, but space requirements increase
Solution Approach 1:
By merging multiple levers and springs into a single compact lever assembly, the patent significantly reduces the space required on the handlebars. The integrated design consolidates what would be multiple separate components into one unit, freeing up space while maintaining full braking functionality.
3Force
If excessive braking force is applied, then braking effectiveness is improved, but wheel skidding occurs on slippery roads
Solution Approach 1:
The single lever design allows the rider to apply partial braking force on slippery surfaces by not fully depressing the lever, or to progressively increase braking force as conditions improve. The independent actuation points allow selective application of braking force to front or rear wheels, enabling more controlled and gradual braking action that reduces the risk of sudden excessive force causing skidding.
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 system provides improved braking performance and feel with enhanced safety by distributing braking force effectively and reducing the risk of wheel skidding, while maintaining a compact design that fits on handlebars without interfering with other components.

AI summary
The present subject matter provides a braking system (200) for a motor vehicle (100). The braking system includes a first brake lever (205) rotatable about a first pivot point (PI) and a second brake lever (210) rotatable about a second pivot point (P2). A single elastic member (240) is operably coupled to the first brake lever (205) and to the second brake lever (210). The elastic member (240) is capable of providing a return force upon actuation of any of or both of the first brake lever (205) and the second brake lever (210). The braking system (200) provides a compact assembly with reduced number of parts. Also, the braking system (200) is mounted to the handlebar (H) without interfering with the headlamp assembly or other ancillary parts.
