Universal Reverse Rotation Pedal Arm for Driver Injury Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedal designs, particularly clutch pedals, face challenges in injury prevention during vehicle collisions due to their complex structures, leading to increased manufacturing costs and differences from brake pedals, which complicates common component usage across vehicles.
Innovation Solution
A universal reverse rotation member is integrated into the pedal arm, allowing it to reversibly rotate away from the driver's leg during collisions, compatible with various pedal types, including brake, clutch, and acceleration pedals, using a mounting bracket, hinge supporters, and a reverse rotation lever to reduce manufacturing costs and enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a reverse rotation structure is applied to the clutch pedal, then driver's leg injury is prevented, but the pedal structure becomes more complex and manufacturing costs increase
Solution Approach 1:
The pedal system is divided into independent functional modules: the pedal arm, the pedal hinge shaft, and the reverse rotation member. This segmentation allows the reverse rotation function to be added as a separate component rather than redesigning the entire pedal structure, thus preventing driver injury while maintaining structural simplicity.
Solution Approach 2:
The reverse rotation member is designed as a universal component that can be applied to both brake pedals and clutch pedals. By creating a multi-functional component that works across different pedal types, the invention avoids increasing overall system complexity while achieving injury prevention across multiple applications.
2Reliability
If different reverse rotation components are used for brake pedal and clutch pedal, then each pedal's specific requirements are met, but manufacturing costs increase
Solution Approach 1:
The reverse rotation member is designed with universal applicability to both brake and clutch pedals. The same component design, including the mounting bracket and reverse rotation lever, can be used across different pedal types, significantly reducing manufacturing costs through economies of scale while maintaining the reliability needed for each specific application.
Solution Approach 2:
While the overall structure of the reverse rotation member remains universal, specific parameters such as the position body dimensions and mounting configurations can be adjusted to meet the specific requirements of different pedal types. This allows a single base design to serve multiple functions with minimal modification.
3Object-affected harmful factors
If the clutch pedal structure is modified to include reverse rotation, then injury prevention is achieved, but the pedal structure becomes more complex compared to brake pedal
Solution Approach 1:
The clutch pedal system is segmented into the existing pedal arm structure and the added reverse rotation member. This segmentation allows the complex reverse rotation function to be isolated in a separate, standardized component rather than being integrated into the pedal arm itself, thus achieving injury prevention without unnecessarily complicating the overall pedal structure.

AI summary
A driver's injury prevention type pedal may include a pedal arm which is rotatably coupled, at an upper portion to a pedal arm hinge which acts as a center of rotation of a pedal stroke, and a universal reverse rotation member which reversibly rotates the pedal arm about the pedal arm hinge and away from a driver which may include a mounting bracket to which the upper portion of the pedal arm is fitted and coupled, and a reverse rotation lever which presses the upper portion of the pedal arm by counterclockwise direction rotation formed by pushing of the pedal arm. In particular, the driver's injury prevention type pedal may be converted into a brake pedal, a clutch pedal, or an acceleration pedal, thereby allowing pedal manufacturing costs to be significantly reduced.
