Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake systems for vehicles with a leaning body frame and two front wheels struggle to manage uneven load distribution and friction differences between the inner and outer front wheels, leading to inconsistent braking performance when turning.
Innovation Solution
A brake system that includes a link mechanism supporting shock absorbers for the front wheels, a brake activator that adjusts braking forces based on detected slipping conditions, and a central rear wheel slip detector to synchronize braking actions, ensuring balanced braking forces across all wheels during turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional brake systems are used on vehicles with leaning body frames and two front wheels, then the braking system can be simple in structure, but the braking performance becomes inconsistent when turning due to uneven load distribution and friction differences between inner and outer front wheels
Solution Approach 1:
The brake system is segmented into independent control units for each wheel, with individual brake actuators and slip detectors. This allows each wheel to be controlled independently based on its specific loading conditions and friction characteristics, resolving the inconsistency in braking performance during turns while maintaining overall system manageability through modular architecture.
Solution Approach 2:
The system applies local quality by detecting slip conditions individually at each wheel and applying braking forces tailored to each wheel's specific conditions. The brake activator adjusts braking forces locally at each wheel based on real-time slip detection, rather than applying uniform braking across all wheels, thereby achieving consistent braking performance despite varying load distribution and friction characteristics.
2Speed
If braking forces are applied to both front wheels simultaneously during turns, then the braking response is fast, but wheel slip occurs due to uneven load distribution between inner and outer wheels
Solution Approach 1:
The brake system dynamically adjusts braking forces based on real-time slip detection. When slip is detected at a particular wheel, the brake activator immediately modifies the braking force applied to that wheel, creating a dynamic response that adapts to changing road conditions and load distribution during turns. This maintains fast overall braking response while preventing wheel slip through continuous adjustment.
Solution Approach 2:
The system incorporates feedback mechanisms through slip detectors at each wheel that continuously monitor wheel rotation and provide real-time information to the brake activator. This feedback loop enables the system to detect slip conditions and adjust braking forces accordingly, maintaining traction control while preserving fast braking response through closed-loop control.

Function Achieved in This Case
The system maintains balanced braking forces across the front wheels, reducing the risk of wheel slip and improving traction by adjusting braking pressure in response to detected slipping conditions, thus enhancing safety and control during turns.
