Vehicle Standing Pedal Debris Prevention via Rocker Axis Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standing pedals for vehicles are prone to debris accumulation, which can compromise their durability and functionality, and existing designs often require complex modifications to address this issue.
Innovation Solution
The pivot axis of the pedal arm and power transmission element are located on a common side of the rocker, with the return spring also positioned on this side, simplifying the design and enhancing durability by preventing debris entry and using hysteresis contact surfaces to maintain a defined power transmission axis, while allowing for flexible geometry and material choices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pedal arm and power transmission element are positioned on opposite sides of the rocker, then debris can be more easily cleared from the mechanism, but the structural complexity increases and durability decreases
Solution Approach 1:
The patent merges the pedal arm and power transmission element to the same side of the rocker, consolidating components that were previously distributed on opposite sides. This simplification reduces the number of parts and assembly steps while maintaining functional integrity, directly addressing the contradiction between reliability and device complexity.
Solution Approach 2:
Instead of the conventional design where the pedal arm and power transmission element are on opposite sides of the rocker, the patent inverts this arrangement by positioning both components on the same side. This inversion simplifies the overall structure and reduces complexity while improving durability through easier maintenance and fewer potential failure points.
2Reliability
If the pedal mechanism is designed with multiple components for debris protection, then durability is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple protective functions into the existing component layout by positioning all critical elements on one side of the rocker. This merging approach provides debris protection through simplified geometry without requiring additional protective components, thereby maintaining durability while reducing space requirements.
3Reliability
If the return spring is positioned on the opposite side of the rocker, then the power transmission axis remains straight, but the design complexity increases and durability decreases
Solution Approach 1:
The patent merges the return spring with the other components on the same side of the rocker, eliminating the need for complex cross-side arrangements. This consolidation simplifies the design while maintaining proper power transmission through the spring's positioning and attachment geometry.
Solution Approach 2:
The patent inverts the conventional return spring positioning by placing it on the same side as the pedal arm and power transmission element rather than on the opposite side. This inversion simplifies the overall design and improves durability through reduced complexity and easier maintenance access.

AI summary
A standing pedal is provided for a vehicle, comprising a support, a pedal arm, a rocker, a return spring for forcing the pedal arm into a direction of an idle position of the pedal arm, and a power transmission element. The return spring is linked to the support and the rocker in a power transmitting manner. The power transmission element is linked to the pedal arm and the rocker in a power transmitting manner. In order to provide a standing pedal for a vehicle, which is robust and shows an enhanced durability, the pivot axis of the pedal arm and the power transmission element are located on a common first side of the rocker with respect to a basic part of the rocker.
