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 mount system for model vehicle engines that includes a hinge secured to the vehicle chassis, allowing the engine to pivot and adjust the center distance between the engine crankshaft and transmission input shaft, enabling engagement and disengagement with the transmission, and a throttle link assembly that accommodates vertical movement without decoupling from the engine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the engine is fixed rigidly to the chassis, then the structural stability is improved, but the handling characteristics cannot be adjusted for different driving conditions

Engineering Contradiction:

Improvestructural stabilityVSAvoidhandling adjustment capability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The engine mount uses a hinge mechanism that allows the engine to pivot dynamically between a running position and a raised position. This dynamic positioning system enables the engine to be adjusted for different driving conditions while maintaining structural stability when fixed in position, directly resolving the contradiction between stability and adaptability.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If the engine position is adjusted horizontally, then the gear mesh alignment is improved, but the throttle control link assembly becomes disconnected from the engine

Engineering Contradiction:

Improvegear mesh alignmentVSAvoidthrottle control connection

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The throttle control link assembly incorporates a vertical movement accommodation feature that allows it to move vertically with the engine when the engine is pivoted on the hinge. This dynamic accommodation maintains the throttle control connection intact during engine position adjustments, preventing disconnection while enabling gear mesh alignment through horizontal positioning changes.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If more space is allocated for engine positioning adjustments, then the handling characteristics can be optimized, but the horizontal space on the chassis increases

Engineering Contradiction:

Improvehandling optimization capabilityVSAvoidchassis horizontal space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Instead of providing additional horizontal space for engine adjustments, the invention utilizes the vertical dimension by pivoting the engine upward on a hinge axis. This vertical movement capability allows for handling optimization through position adjustment without increasing the horizontal footprint on the chassis, effectively resolving the space constraint contradiction.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
