Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control and model vehicles are expensive to construct and maintain, and they often lack optimal handling characteristics, making it difficult to adjust them for different driving conditions.
Innovation Solution
A rocker arm design for model vehicles that allows for adjustable engine positioning and suspension components, enabling better gear meshing and improved handling by accommodating various gear sizes and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If model vehicles use fixed engine positioning and suspension components, then manufacturing is simpler, but handling characteristics are suboptimal and cannot be adjusted for different driving conditions
Solution Approach 1:
The rocker arm assembly incorporates a pivot member that allows the rocker arm to rotate about a pivot axis, enabling dynamic adjustment of engine positioning and suspension geometry. This rotational capability permits the vehicle to adapt its handling characteristics for different driving conditions while maintaining a relatively simple overall structure.
Solution Approach 2:
The rocker arm is divided into a first portion and a second portion spaced from each other along the rotational axis, with each portion having an opening for receiving a pivot member. This segmentation allows independent adjustment of different suspension parameters while using a single integrated component, balancing adaptability with structural simplicity.
2Reliability
If model vehicles use adjustable engine positioning for optimal gear meshing, then vehicle performance improves, but construction and maintenance costs increase
Solution Approach 1:
The adjustable engine positioning is achieved through the pivotable rocker arm mechanism, which allows the engine mount position to be dynamically adjusted relative to the transmission. This ensures optimal gear meshing for different gear sizes and vehicle configurations without requiring complex adjustable mechanisms, thereby maintaining cost-effectiveness while improving reliability.
Solution Approach 2:
The rocker arm assembly serves multiple functions: it acts as both a suspension component and an engine mounting structure with adjustable positioning. This multi-functionality eliminates the need for separate adjustment mechanisms, reducing manufacturing complexity and cost while ensuring reliable gear meshing across different driving conditions.

AI summary
A rocker arm for a model vehicle is provided, comprising a first portion and second portion each having an input and an output arm and each having an opening for receiving a pivot member about which the portions rotate. The first and second portions are secured for rotation together about a rotational axis through the respective openings and are spaced apart generally along the rotational axis. The rocker arm further comprises a suspension input coupling member that extends between the input arms of the first and second portions, where the input arms are spaced along the input coupling member, and a suspension output coupling member that extends between the outputs arms of the first and second portions, where the output arms are spaced along the output coupling member.
