Brake Pedal Device With Segmented Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-ride type vehicles, such as motorcycles, face challenges in maintaining stability and operability, especially during rough road conditions or competitions, due to the need for enhanced foot placement and operation of the brake pedal to prevent slippage and confusion between different operational directions.
Innovation Solution
A brake pedal device with a rotatable arm portion and a pedal portion featuring distinct operation surfaces and unevenness patterns, including a first operation portion for brake operation and a second operation portion for stability enhancement, with inclined and slit grooves to prevent slippage and inadvertent contact, allowing for improved vehicle control and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single operation portion is provided on the brake pedal, then the structure is simple, but the occupant cannot reliably push from different directions for stability enhancement
Solution Approach 1:
The pedal portion is divided into multiple operation portions (first operation portion and second operation portion) located at different positions and orientations. This segmentation allows the occupant to push from different directions (upward on the first operation portion, downward on the second operation portion) to enhance stability during vehicle operation, directly resolving the contradiction between versatility and simplicity.
2Reliability
If the pedal surface is made smooth, then the manufacturing is simple, but the occupant's foot slips during operation
Solution Approach 1:
Uneven portions are formed at specific locations on the operation surfaces (first uneven portion on the first operation portion, second uneven portion on the second operation portion) rather than making the entire surface complex. This local quality approach provides effective anti-slip performance where needed while keeping the overall manufacturing process relatively simple.
3Adaptability or versatility
If operation portions are provided on both upper and lower surfaces, then the occupant can push from different directions for stability, but the structure becomes more complex
Solution Approach 1:
The pedal portion is designed to serve multiple functions through its dual operation portions: the first operation portion on the upper surface allows upward pushing for one stability function, while the second operation portion on the lower surface allows downward pushing for another stability function. This multi-functionality approach enables the single pedal structure to handle multiple operational needs without requiring separate components.
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 brake pedal device enhances operability and stability by reducing slippage and confusion through distinct operational directions and surface features, improving the overall performance of saddle-ride type vehicles during dynamic conditions.
Implementation Method 1
a first uneven portion formed on at least a part of the first operation portion, a second uneven portion formed on at least a part of the second operation portion... the unevenness prevents slipping and slippage of the shoes is curbed
