Utility Vehicle Throttle Pedal Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility vehicle throttle pedals are difficult to assemble and service due to the complexity of connecting and adjusting the throttle cable, which requires inserting the cable through openings and using retaining members or fasteners, making the process time-consuming and hard to access.
Innovation Solution
A utility vehicle throttle pedal design featuring a throttle connect rod that extends under the pedal, allowing tool-free connection and disconnection, and an adjustable sleeve for cable length and tension adjustment without openings or protruding components on the pedal face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If throttle cable is connected through openings with retaining members or clips, then the connection is secure, but the assembly and servicing becomes difficult and time-consuming
Solution Approach 1:
The patent removes the traditional retaining members, clips, and fasteners from the pedal face, extracting the problematic connection components. Instead, the throttle cable connects directly to the underside of the pedal body, eliminating the need for separate retaining elements and simplifying both assembly and servicing operations.
Solution Approach 2:
The patent changes the connection dimension by moving the throttle cable connection from the face (top surface) of the pedal to the underside. This dimensional shift allows the cable to connect through the thickness of the pedal body without requiring openings or protruding fasteners on the face, resolving the contradiction between secure connection and ease of operation.
2Stability of the object's composition
If throttle cable connection requires openings and retaining members, then the connection is stable, but the servicing and adjustment becomes hard to access
Solution Approach 1:
The patent extracts the retaining members and fasteners from the pedal face, eliminating the components that create accessibility problems. The throttle cable now connects directly to the underside of the pedal body, making the connection point accessible for servicing and adjustment without requiring disassembly of face-mounted components.
Solution Approach 2:
Instead of connecting the throttle cable to the face of the pedal as in traditional designs, the patent inverts the connection approach by attaching the cable to the underside of the pedal body. This inversion makes the connection point accessible from below, improving servicing accessibility while maintaining connection stability.
3Reliability
If throttle cable connection uses multiple components, then the connection is secure, but the device complexity increases
Solution Approach 1:
The patent merges the throttle cable connection function directly into the pedal body structure, eliminating the need for separate retaining members, clips, and fasteners. The pedal body itself provides the connection interface through its underside, reducing the total number of components while maintaining reliable connection.
Solution Approach 2:
The pedal body serves multiple functions: it provides the structural platform for the pedal mechanism and simultaneously serves as the connection interface for the throttle cable. This multi-functionality eliminates the need for dedicated retaining components, simplifying the overall assembly while maintaining connection reliability.

AI summary
A utility vehicle throttle pedal includes a one piece molded plastic body pivotably mounted to a bracket, and having a face, an underside and first and second sidewalls between the face and underside. A throttle connect rod is positioned on the underside of the plastic body and has first and second ends entering first and second openings in the first and second sidewalls. A throttle cable is adjustably attached to the throttle connect rod. The throttle connect rod may be manually connected and disconnected from the throttle pedal without use of tools.
