Adjustable Motor Vehicle Pedal With Modular Lever Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle pedals are inflexible and difficult to adapt to various vehicle interiors and mounting positions, leading to challenges in finding a suitable design for proper mounting and comfortable operation.
Innovation Solution
An adjustable motor vehicle pedal with a sensor module and adjustable coupling between lever arms, allowing the foot pad to be repositioned relative to the controller, enabling flexible mounting and operation across different vehicle configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the second end of the lever arm extends outwardly far from the front wall of the cab or the foot pad is positioned high or low, then sufficient rotational movement range is achieved, but operation becomes difficult or uncomfortable
Solution Approach 1:
The pedal system employs a spring-biased lever arm that can dynamically adjust its position. The spring mechanism allows the lever arm to return to its at-rest position after being depressed, providing a dynamic, adjustable range of motion that adapts to different operational requirements while maintaining comfort through controlled mechanical feedback
2Adaptability or versatility
If a variety of different pedal designs with different shapes, lengths, and angles are provided, then adaptability to different motor vehicle interiors is improved, but device complexity and selection difficulty increase
Solution Approach 1:
The pedal controller is designed as a universal mounting interface that can accommodate multiple lever arm configurations. The controller housing includes a mounting plate with multiple mounting hole positions, allowing a single controller design to support various lever arm lengths, angles, and foot pad positions, thereby providing multi-functionality without requiring multiple specialized pedal designs
3Ease of manufacture
If the lever arm configuration is fixed, then manufacturing simplicity is maintained, but adaptability to different mounting positions and vehicle interiors is reduced
Solution Approach 1:
The pedal system is segmented into distinct modular components: a pedal controller with mounting means, a separable lever arm, and an adjustable foot pad. This segmentation allows each component to be manufactured independently using standardized processes, while the modular assembly enables adaptability to different mounting positions through reconfiguration of the same basic components

AI summary
An adjustable vehicle control pedal comprises a first arm having a first end rotatable along a plane between first and second positions. The first end defines a first through opening extending nonparallel to the plane. A second arm has a first end defining a second through opening extending nonparallel to a long dimension of the second arm. The second arm is repositionable in relation to the first arm among a plurality of positions in which the first and second through openings are in substantially coaxial adjacent registration with one another. An insert is receivable through the first and second through openings in each of the plurality of positions to lock the second arm against rotation in relation to the first arm along the plane. A position sensor is responsive to movement of the first arm between the first and second positions.
