Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing braking systems with a singular brake pedal profile, featuring offset segments, experience mechanical stress and poor interaction with the master cylinder, leading to unreliable braking conditions, especially in frontal impacts.
Innovation Solution
A braking system with a brake pedal having a first segment carrying the actuating shoe and a second offset segment, where a projecting appendage extends parallel to the first segment to interact with the master cylinder, ensuring a stable and controlled thrust for reliable braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brake pedal uses a singular profile with offset segments, then the architecture meets safety regulations and frontal impact requirements, but the interaction with the master cylinder becomes poor and braking reliability deteriorates
Solution Approach 1:
The brake pedal is divided into two offset segments: a first segment carrying the actuating pad and a second segment rotatably mounted on the pedal yoke. This segmentation allows the pedal to meet safety regulations for frontal impacts while the first segment can still effectively interact with the master cylinder through its specific geometric configuration
Solution Approach 2:
The first segment is designed with specific local geometric qualities including a major axis and minor axis with particular orientation relationships. The pad is positioned at specific locations relative to these axes, creating localized interaction zones that optimize the force transmission to the master cylinder while maintaining overall structural integrity under impact conditions
2Object-affected harmful factors
If the brake pedal has offset segments, then safety regulations are met, but mechanical stresses increase and braking conditions become random and unstable
Solution Approach 1:
The pedal segments are designed with asymmetric geometric relationships. The first segment has a major axis and minor axis with specific orientation angles, and the pad is positioned asymmetrically relative to these axes. This asymmetric configuration creates stable, predictable force transmission paths that reduce random variations in braking conditions while maintaining protection against frontal impacts
3Adaptability or versatility
If the pedal segments are offset, then regulatory requirements are satisfied, but the thrust on the master cylinder becomes uncontrolled and braking performance degrades
Solution Approach 1:
The first segment is pre-configured with specific geometric properties including oriented major and minor axes, and the pad is pre-positioned at predetermined locations relative to these axes. This preliminary geometric configuration ensures that when force is applied to the pad, the resulting thrust on the master cylinder follows a controlled, predictable path, maintaining manufacturing precision and braking performance while complying with regulatory requirements
