Throttle Pedal Assembly Adjustable Idle Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing throttle pedal assemblies lack adjustability, which limits their ability to accommodate ergonomic preferences and maintain consistent throttle signal output during adjustments.
Innovation Solution
A throttle pedal assembly design featuring a pivotable pedal and sensor components with an adjustment member that allows for adjustable positioning without relative displacement between the sensed and sensing elements, ensuring consistent throttle signal output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pedal position is adjusted for ergonomic preferences, then the ease of operation is improved, but the throttle signal output consistency deteriorates
Solution Approach 1:
An adjustment member is introduced as an intermediary component between the pedal and the sensor assembly. This adjustment member enables independent adjustment of the pedal's idle position without affecting the sensor elements' relative alignment, thus maintaining signal consistency while improving ergonomic adjustability
Solution Approach 2:
The system is segmented into independent adjustment and sensing functions. The adjustment member handles pedal position adjustment separately from the sensor assembly, allowing the pedal to be repositioned without causing relative displacement between the sensed and sensing elements
2Adaptability or versatility
If the pedal structure is made adjustable, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
A simple adjustment member serves as a mediator that provides the necessary adaptability without introducing complex mechanisms. The adjustment member can be a basic mechanical component that enables position changes while maintaining simplicity in the overall system design
Solution Approach 2:
The system transitions from a fixed pedal position to a dynamically adjustable position. The adjustment member enables the pedal to be repositioned as needed, providing adaptability while keeping the adjustment mechanism simple and straightforward

AI summary
A throttle pedal assembly may include: a base; a pedal movably mounted on the base; and an adjustment member extending at least between a first reference location of the throttle pedal assembly and an adjustment surface at an end of the adjustment member. The adjustment member may be adjustable to adjust an adjustment distance from the first reference location of the throttle pedal assembly to the adjustment surface. The throttle pedal assembly may be operable to indicate a throttle level according to relative positions of a second reference location of the throttle pedal assembly and a third reference location of the throttle pedal assembly. Adjusting the adjustment distance may cause an idle position of the pedal to move relative to base and maintains relative positions of the second and third reference locations when the pedal is in the idle position.
